๐Ÿงด

Low pH Formula (5.0โ€“6.0)

Matches the skin's natural acid mantle to prevent over-stripping, reduce transepidermal water loss, and maintain the microbiome balance after every wash.

๐Ÿ”ฌ Ingredient Breakdown

๐ŸŒฒ Betula Platyphylla Japonica Juice (Birch Juice) 10,000ppm / ~1% Star Ingredient

Silver birch sap harvested in spring from Inje County, South Korea. Naturally rich in Natural Moisturizing Factor (NMF) โ€” a complex of amino acids, lactic acid, pyrrolidone carboxylic acid (PCA), and sugars that mirrors the skin's own moisture system.

  • Hydration: Contains 17 free amino acids that act as humectants, binding water within the stratum corneum.
  • Antioxidant: Natural vitamins C and B (niacinamide) protect against free radical damage and brighten uneven tone.
  • Anti-inflammatory: Birch polyphenols reduce pro-inflammatory cytokine activity, calming redness and stressed skin.
  • Barrier support: Minerals and trace elements reinforce the skin's lipid barrier and support collagen production.
โœ…
Sourced exclusively from Inje County's pristine birch forests. Concentration of 10,000ppm (1%) is clearly stated and represents a meaningful active dose in a rinse-off formula.

๐Ÿ’ง Glycerin Position 2 โ€” High % Proven

A foundational humectant that forms the hydrating backbone of this cleanser. Glycerin is naturally present in skin as part of NMF and is widely regarded as one of the most effective moisturizing agents in skincare science.

  • Mechanism: Attracts water from the environment and deeper skin layers to the stratum corneum, maintaining surface hydration even post-rinse.
  • Barrier function: Keeps intercellular lipids flexible, strengthening the skin barrier against environmental stressors.
  • Penetration: Small molecular weight allows it to carry other humectants and actives into deeper epidermal layers.

๐Ÿงฌ Sodium Hyaluronate + Hyaluronic Acid Dual-weight HA Proven

This cleanser features both forms of hyaluronic acid. Sodium Hyaluronate (lower MW) penetrates deeper into the epidermis, while free Hyaluronic Acid provides surface-level plumping and moisture retention.

  • Water binding: HA holds up to 1,000ร— its own weight in water, delivering immediate and sustained hydration.
  • Rinse-off benefit: Even in a wash-off formula, HA leaves behind a conditioning film that reduces post-cleanse tightness.
  • Anti-aging: Regular use supports plumpness and reduces the appearance of fine lines caused by dehydration.

๐ŸŒฟ Artemisia Annua Extract (Sweet Wormwood) Active botanical Proven

A powerful anti-inflammatory botanical widely used in K-beauty for its ability to soothe redness, calm breakouts, and support skin recovery. Clinically studied for eczema and dry skin relief.

  • Anti-inflammatory: Artemisinin and flavonoid compounds inhibit NF-ฮบB pathway, reducing inflammatory skin responses.
  • Anti-bacterial: Exhibits antimicrobial properties against acne-causing bacteria without disrupting the skin microbiome.
  • Dermatologically recommended: Used in clinical settings for itch, eczema, and post-treatment skin calming protocols.

๐Ÿ”ต Glyceryl Glucoside Aquaporin activator Promising

An innovative hydration ingredient originally isolated from extremophile organisms that survive extreme dryness. It triggers the skin's own aquaporin-3 (AQP3) water channels, improving internal moisture transport.

  • Aquaporin activation: Studies show Glyceryl Glucoside upregulates AQP3 expression, improving long-term moisture retention from within.
  • Barrier repair: Supports lamellar body secretion and helps rebuild the lipid matrix of the stratum corneum.
  • Clinical data: A 2019 study demonstrated statistically significant improvements in skin hydration and barrier function after 4 weeks of use.
๐Ÿ’ก
Its presence in a cleanser โ€” even at rinse-off stage โ€” leaves a residual conditioning effect that contributes to the "soft skin" feeling users report post-wash.

๐ŸŠ Ascorbic Acid (Vitamin C) Antioxidant dose Proven

Pure L-ascorbic acid provides antioxidant protection and mild brightening during the cleanse. At low concentrations in a rinse-off formula, it primarily works as an antioxidant and free radical scavenger rather than a treatment-level active.

  • Antioxidant: Neutralizes free radicals caused by UV, pollution, and environmental stressors before they degrade collagen.
  • Collagen support: Essential cofactor for collagen synthesis, contributing to skin firmness over time.
  • Brightening: Inhibits tyrosinase activity, helping to even skin tone with consistent use.
โš ๏ธ
At rinse-off concentrations, the brightening effect is mild compared to leave-on vitamin C serums. For targeted hyperpigmentation treatment, pair with a dedicated vitamin C serum after cleansing.

๐Ÿ“ How to Use

1

Wet Your Face & Hands

Splash your face with lukewarm water. Dispense a pea-to-nickel-sized amount (about 1โ€“2 pumps or small squeeze) onto damp palms.

2

Lather into a Rich Foam

Rub your palms together with a little water to activate the gel into a creamy, airy foam. The gel transforms into lather quickly โ€” no foaming net needed.

3

Massage Gently onto Face

Apply foam to face using gentle circular motions, working outward from the center. Spend 30โ€“60 seconds massaging โ€” include the hairline, nose creases, and jawline. Avoid the eye area.

4

Rinse Thoroughly

Rinse off completely with lukewarm water. Finish with a brief cool rinse to help close pores and lock in the dewy feel. Pat โ€” do not rub โ€” dry with a clean towel.

5

Continue Your Routine Immediately

Apply your toner, essence, or serum while skin is still slightly damp to maximize absorption. Follow with moisturizer to seal in the hydration delivered during cleansing.

๐Ÿ‘ค Who Is It For?

โœ… Perfect for you if:

  • Your skin feels tight or dry after cleansing
  • You have sensitive, dehydrated, or barrier-compromised skin
  • You're pregnant or breastfeeding and need a safe cleanser
  • You have fungal acne or malassezia-prone skin
  • You prefer fragrance-free, low-irritant formulas
  • You want a cleanser that actively hydrates while it cleanses
  • You wear sunscreen or light makeup that needs a thorough water-based cleanse
  • You're looking for a gentle everyday cleanser suitable for morning and evening

โŒ Consider alternatives if:

  • You wear heavy, full-coverage foundation or waterproof makeup (use an oil cleanser first)
  • You have a known coconut or tree nut allergy
  • You prefer a non-foaming, lotion-style cleanser
  • You need strong exfoliation (use a dedicated exfoliant separately)
  • You have extremely oily skin that needs a more clarifying, oil-control cleanser
  • You want a single-step makeup remover and cleanser in one

๐ŸŽฏ Skin Type Compatibility

Dry Skin โ˜…โ˜…โ˜…โ˜…โ˜… Excellent

The dual HA complex and birch juice NMF leave skin feeling conditioned rather than stripped. No post-wash tightness โ€” a common complaint for dry skin users with other cleansers.

Combination Skin โ˜…โ˜…โ˜…โ˜…โ˜… Excellent

Balances oil-prone T-zones without over-drying drier cheek areas. The low-pH formula respects the skin's natural balance across different facial zones.

Sensitive Skin โ˜…โ˜…โ˜…โ˜…โ˜… Excellent

Fragrance-free, no drying alcohols, and Dermatest "EXCELLENT" certified for skin compatibility. Artemisia Annua actively soothes redness and reactive skin during cleansing.

Acne-Prone Skin โ˜…โ˜…โ˜…โ˜…โ˜… Excellent

Non-comedogenic (1/5 rating), fungal acne safe, and contains Glyceryl Caprylate with antimicrobial properties. Cleanses pores effectively without disrupting the skin microbiome.

Oily Skin โ˜…โ˜…โ˜…โ˜…โ˜† Good

Effectively removes sebum and pore buildup without over-stripping. Those with very oily skin may prefer pairing with an oil-control toner after cleansing for more matte results.

Dehydrated / Compromised Barrier โ˜…โ˜…โ˜…โ˜…โ˜… Excellent

Glyceryl Glucoside activates aquaporin channels to restore water transport. Ideal for skin recovering from over-exfoliation, retinoid purging, or environmental barrier damage.

๐Ÿ“ˆ Results Timeline

First Use

Immediate Softness & No Tightness

The most common first-use feedback: skin feels unexpectedly soft and supple after rinsing off, with none of the post-wash dryness typical of cleansers. The gel-to-foam experience feels luxurious yet gentle.

92% noticed instantly
Week 1โ€“2

Reduced Post-Cleanse Dryness

Skin begins adapting to the low-pH environment. Users with previously tight, reactive skin after washing report a noticeable reduction in the "squeaky clean" sensation. Redness and irritation around the nose and cheeks begins to calm.

78% saw improvement
Week 3โ€“4

Improved Skin Texture & Hydration

With consistent AM/PM use, the glyceryl glucoside-driven aquaporin activation begins to show in improved skin plumpness. Skin texture feels smoother, and the overall hydration level throughout the day improves noticeably.

71% noticed improvement
Month 2+

Calmer, More Balanced Complexion

Long-term users report fewer breakouts (likely from non-comedogenic, microbiome-friendly surfactants), more even skin tone (from antioxidant Vitamin C and birch polyphenols), and an overall more resilient skin barrier.

โ“ Frequently Asked Questions

Yes โ€” this cleanser is considered safe for use during pregnancy and breastfeeding. It contains no retinoids, salicylic acid, hydroquinone, chemical sunscreen actives, or other ingredients flagged as unsafe during pregnancy. All surfactants are coconut-derived, and the botanical extracts (birch juice, artemisia, chamomile) are used at cosmetic concentrations in a rinse-off formula. As with any skincare product during pregnancy, consult your healthcare provider if you have specific sensitivities or medical concerns.

Yes โ€” this cleanser is considered fungal acne safe. It contains no polysorbates, fermented ingredients, or long-chain fatty acids that are known to feed malassezia. Notably, it contains Glyceryl Caprylate, which is an antimicrobial ester shown to inhibit fungal and bacterial growth. As a rinse-off product, even borderline ingredients pose minimal risk. This cleanser is widely used by the fungal acne community without reported issues.

Absolutely โ€” this cleanser is an excellent pairing for all actives. Its low pH (5.0โ€“6.0) prepares the skin for AHAs and BHAs by maintaining an acidic environment that allows these acids to function optimally. It does not disrupt the skin barrier before retinol application and its hydrating properties can help reduce the dryness or irritation sometimes associated with retinoid use. Apply actives after cleansing, once skin is slightly damp, for best absorption.

This cleanser is best suited for dry, combination, sensitive, dehydrated, and acne-prone skin types. It excels for anyone who experiences post-wash tightness, dryness, or irritation from most cleansers. It also works well for oily skin, though very oily skin types may prefer pairing it with an oil-control toner. The formula is genuinely suitable for all skin types thanks to its balanced pH, gentle surfactant blend, and hydrating actives.

Most users notice an immediate difference after the first use โ€” skin feels soft and non-tight after rinsing. Over 1โ€“2 weeks of twice-daily use, post-cleanse dryness and redness typically diminish significantly. By weeks 3โ€“4, skin texture improves and overall hydration levels throughout the day increase. For the full benefits of aquaporin activation and skin barrier strengthening, allow 4โ€“8 weeks of consistent use. Cleansers work cumulatively โ€” consistency is key.

Use this as Step 1 of your skincare routine, both morning and evening. In the evening, if you wear sunscreen, foundation, or heavy makeup, use an oil-based cleanser first (double cleansing), then follow with this as your second, water-based cleanse. In the morning, this cleanser alone is sufficient. After cleansing, continue with toner, essence, serum, moisturizer, and sunscreen (AM only).

No โ€” this cleanser has a comedogenic rating of 1/5, which is considered very low. It contains no heavy oils or waxes. Chamomile Flower Oil (Anthemis Nobilis) and Pine Needle Oil (Pinus Sylvestris) both have comedogenic ratings of 0โ€“1. As a rinse-off formula, even ingredients with slightly higher ratings pose minimal risk since they do not remain on the skin long enough to occlude pores. This cleanser has been used extensively by acne-prone users without reported pore-clogging issues.

The recommended Period After Opening (PAO) is 12 months. With twice-daily use, a 150ml tube typically lasts 3โ€“4 months for most users, well within the PAO window. The 1,2-Hexanediol, Caprylyl Glycol, and Disodium EDTA in the formula act as preservatives to maintain stability and prevent microbial contamination throughout the product's lifespan. Store at room temperature away from direct sunlight. Discard if texture, color, or scent changes notably.

โ˜…โ˜…โ˜…โ˜…โ˜…
4.7 out of 5

Verdict: The Round Lab Birch Juice Moisturising Cleanser is one of the most compelling hydrating cleansers in K-beauty today. Its combination of a clinically measured low pH, genuine aquaporin-activating technology (Glyceryl Glucoside), dual-weight hyaluronic acid, and a clean, fragrance-free surfactant system delivers a cleanse that leaves skin measurably better-hydrated โ€” not just "less stripped." The Dermatest "Excellent" certification, fungal acne safety, and pregnancy-safe status make it a genuine all-rounder. Best suited to dry, sensitive, combination, and barrier-compromised skin types, it earns its cult status as a daily-use cleanser that works harder than most people expect from a step they rinse down the drain.

At rinse-off concentrations, the brightening effect is mild compared to leave-on vitamin C serums. For targeted hyperpigmentation treatment, pair with a dedicated vitamin C serum after cleansing.

๐Ÿ“ How to Use

1

Wet Your Face & Hands

Splash your face with lukewarm water. Dispense a pea-to-nickel-sized amount (about 1โ€“2 pumps or small squeeze) onto damp palms.

2

Lather into a Rich Foam

Rub your palms together with a little water to activate the gel into a creamy, airy foam. The gel transforms into lather quickly โ€” no foaming net needed.

3

Massage Gently onto Face

Apply foam to face using gentle circular motions, working outward from the center. Spend 30โ€“60 seconds massaging โ€” include the hairline, nose creases, and jawline. Avoid the eye area.

4

Rinse Thoroughly

Rinse off completely with lukewarm water. Finish with a brief cool rinse to help close pores and lock in the dewy feel. Pat โ€” do not rub โ€” dry with a clean towel.

5

Continue Your Routine Immediately

Apply your toner, essence, or serum while skin is still slightly damp to maximize absorption. Follow with moisturizer to seal in the hydration delivered during cleansing.

๐Ÿ‘ค Who Is It For?

โœ… Perfect for you if:

  • Your skin feels tight or dry after cleansing
  • You have sensitive, dehydrated, or barrier-compromised skin
  • You're pregnant or breastfeeding and need a safe cleanser
  • You have fungal acne or malassezia-prone skin
  • You prefer fragrance-free, low-irritant formulas
  • You want a cleanser that actively hydrates while it cleanses
  • You wear sunscreen or light makeup that needs a thorough water-based cleanse
  • You're looking for a gentle everyday cleanser suitable for morning and evening

โŒ Consider alternatives if:

  • You wear heavy, full-coverage foundation or waterproof makeup (use an oil cleanser first)
  • You have a known coconut or tree nut allergy
  • You prefer a non-foaming, lotion-style cleanser
  • You need strong exfoliation (use a dedicated exfoliant separately)
  • You have extremely oily skin that needs a more clarifying, oil-control cleanser
  • You want a single-step makeup remover and cleanser in one

๐ŸŽฏ Skin Type Compatibility

Dry Skin โ˜…โ˜…โ˜…โ˜…โ˜… Excellent

The dual HA complex and birch juice NMF leave skin feeling conditioned rather than stripped. No post-wash tightness โ€” a common complaint for dry skin users with other cleansers.

Combination Skin โ˜…โ˜…โ˜…โ˜…โ˜… Excellent

Balances oil-prone T-zones without over-drying drier cheek areas. The low-pH formula respects the skin's natural balance across different facial zones.

Sensitive Skin โ˜…โ˜…โ˜…โ˜…โ˜… Excellent

Fragrance-free, no drying alcohols, and Dermatest "EXCELLENT" certified for skin compatibility. Artemisia Annua actively soothes redness and reactive skin during cleansing.

Acne-Prone Skin โ˜…โ˜…โ˜…โ˜…โ˜… Excellent

Non-comedogenic (1/5 rating), fungal acne safe, and contains Glyceryl Caprylate with antimicrobial properties. Cleanses pores effectively without disrupting the skin microbiome.

Oily Skin โ˜…โ˜…โ˜…โ˜…โ˜† Good

Effectively removes sebum and pore buildup without over-stripping. Those with very oily skin may prefer pairing with an oil-control toner after cleansing for more matte results.

Dehydrated / Compromised Barrier โ˜…โ˜…โ˜…โ˜…โ˜… Excellent

Glyceryl Glucoside activates aquaporin channels to restore water transport. Ideal for skin recovering from over-exfoliation, retinoid purging, or environmental barrier damage.

๐Ÿ“ˆ Results Timeline

First Use

Immediate Softness & No Tightness

The most common first-use feedback: skin feels unexpectedly soft and supple after rinsing off, with none of the post-wash dryness typical of cleansers. The gel-to-foam experience feels luxurious yet gentle.

92% noticed instantly
Week 1โ€“2

Reduced Post-Cleanse Dryness

Skin begins adapting to the low-pH environment. Users with previously tight, reactive skin after washing report a noticeable reduction in the "squeaky clean" sensation. Redness and irritation around the nose and cheeks begins to calm.

78% saw improvement
Week 3โ€“4

Improved Skin Texture & Hydration

With consistent AM/PM use, the glyceryl glucoside-driven aquaporin activation begins to show in improved skin plumpness. Skin texture feels smoother, and the overall hydration level throughout the day improves noticeably.

71% noticed improvement
Month 2+

Calmer, More Balanced Complexion

Long-term users report fewer breakouts (likely from non-comedogenic, microbiome-friendly surfactants), more even skin tone (from antioxidant Vitamin C and birch polyphenols), and an overall more resilient skin barrier.

โ“ Frequently Asked Questions

Yes โ€” this cleanser is considered safe for use during pregnancy and breastfeeding. It contains no retinoids, salicylic acid, hydroquinone, chemical sunscreen actives, or other ingredients flagged as unsafe during pregnancy. All surfactants are coconut-derived, and the botanical extracts (birch juice, artemisia, chamomile) are used at cosmetic concentrations in a rinse-off formula. As with any skincare product during pregnancy, consult your healthcare provider if you have specific sensitivities or medical concerns.

Yes โ€” this cleanser is considered fungal acne safe. It contains no polysorbates, fermented ingredients, or long-chain fatty acids that are known to feed malassezia. Notably, it contains Glyceryl Caprylate, which is an antimicrobial ester shown to inhibit fungal and bacterial growth. As a rinse-off product, even borderline ingredients pose minimal risk. This cleanser is widely used by the fungal acne community without reported issues.

Absolutely โ€” this cleanser is an excellent pairing for all actives. Its low pH (5.0โ€“6.0) prepares the skin for AHAs and BHAs by maintaining an acidic environment that allows these acids to function optimally. It does not disrupt the skin barrier before retinol application and its hydrating properties can help reduce the dryness or irritation sometimes associated with retinoid use. Apply actives after cleansing, once skin is slightly damp, for best absorption.

This cleanser is best suited for dry, combination, sensitive, dehydrated, and acne-prone skin types. It excels for anyone who experiences post-wash tightness, dryness, or irritation from most cleansers. It also works well for oily skin, though very oily skin types may prefer pairing it with an oil-control toner. The formula is genuinely suitable for all skin types thanks to its balanced pH, gentle surfactant blend, and hydrating actives.

Most users notice an immediate difference after the first use โ€” skin feels soft and non-tight after rinsing. Over 1โ€“2 weeks of twice-daily use, post-cleanse dryness and redness typically diminish significantly. By weeks 3โ€“4, skin texture improves and overall hydration levels throughout the day increase. For the full benefits of aquaporin activation and skin barrier strengthening, allow 4โ€“8 weeks of consistent use. Cleansers work cumulatively โ€” consistency is key.

Use this as Step 1 of your skincare routine, both morning and evening. In the evening, if you wear sunscreen, foundation, or heavy makeup, use an oil-based cleanser first (double cleansing), then follow with this as your second, water-based cleanse. In the morning, this cleanser alone is sufficient. After cleansing, continue with toner, essence, serum, moisturizer, and sunscreen (AM only).

No โ€” this cleanser has a comedogenic rating of 1/5, which is considered very low. It contains no heavy oils or waxes. Chamomile Flower Oil (Anthemis Nobilis) and Pine Needle Oil (Pinus Sylvestris) both have comedogenic ratings of 0โ€“1. As a rinse-off formula, even ingredients with slightly higher ratings pose minimal risk since they do not remain on the skin long enough to occlude pores. This cleanser has been used extensively by acne-prone users without reported pore-clogging issues.

The recommended Period After Opening (PAO) is 12 months. With twice-daily use, a 150ml tube typically lasts 3โ€“4 months for most users, well within the PAO window. The 1,2-Hexanediol, Caprylyl Glycol, and Disodium EDTA in the formula act as preservatives to maintain stability and prevent microbial contamination throughout the product's lifespan. Store at room temperature away from direct sunlight. Discard if texture, color, or scent changes notably.

Verdict: The Round Lab Birch Juice Moisturising Cleanser is one of the most compelling hydrating cleansers in K-beauty today. Its combination of a clinically measured low pH, genuine aquaporin-activating technology (Glyceryl Glucoside), dual-weight hyaluronic acid, and a clean, fragrance-free surfactant system delivers a cleanse that leaves skin measurably better-hydrated โ€” not just "less stripped." The Dermatest "Excellent" certification, fungal acne safety, and pregnancy-safe status make it a genuine all-rounder. Best suited to dry, sensitive, combination, and barrier-compromised skin types, it earns its cult status as a daily-use cleanser that works harder than most people expect from a step they rinse down the drain.
