No.1 Pure-Full Calming Herb Toner
A lightweight, watery toner with 93% pure botanical extracts โ Centella Asiatica, Heartleaf, and Licorice Root โ clinically proven to calm redness, control excess oil, and clear breakouts in as little as 2 weeks. Low pH 5.5, fragrance-free, and non-comedogenic.
โจ Texture & Feel
93% Botanical Extract Base
Instead of plain water, 93% of the formula is pure Centella Asiatica (39.2%), Heartleaf (28.1%), and Licorice Root (25.7%) extracts โ delivering concentrated herbal actives with every application.
Clinically Proven Results
Independently tested: excess oil reduced by 29.9%, blackheads by 30.9%, and whiteheads by 29% in just 4 weeks. Redness reduced by 14.8% and breakouts by 46.3% in just 2 weeks.
Skin-Barrier Friendly pH 5.5
Formulated at a gentle pH 5.5, close to the skin's natural acid mantle. This preserves the microbiome and prevents disruption of the protective barrier while delivering active botanicals.
Dual Calming & Oil Control
Heartleaf extract uniquely cools down heated, inflamed skin while Centella Asiatica repairs barrier damage. Together they address both the visible redness and the underlying sebum overproduction.
๐ก๏ธ Safety & Compatibility
Contains no retinoids, salicylic acid, hydroquinone, or chemical sunscreen filters. All 18 ingredients are botanical extracts, humectants, and gentle skin-conditioning agents considered safe for use during pregnancy and breastfeeding. Always consult your OB-GYN for personal advice.
Free from fermented ingredients, fatty acid esters, polysorbates, and oils that feed Malassezia yeast. The formula is FA-safe, making it a go-to toner for fungal acne sufferers who need calming and hydration without triggering flare-ups.
No pore-clogging oils or high-comedogenic ingredients. Rated 1 out of 5 on the comedogenic scale. Officially labeled non-comedogenic by the brand and confirmed safe for acne-prone skin by the formula composition.
Contains no added fragrances, essential oils, or common allergens. The faint herbaceous scent comes naturally from the high-concentration botanical extracts. Suitable for reactive and sensitized skin types.
Contains no denatured alcohol (Alcohol Denat.), ethanol, or other drying alcohols. Safe for dry skin, eczema-prone, and compromised barriers. Propanediol and Butylene Glycol used as mild, non-irritating solvents.
Pairs well with most actives. Use before retinol, niacinamide, or AHA/BHA treatments. The calming Centella and Panthenol can help buffer potential irritation from stronger actives. Avoid layering with high-pH products to preserve its skin-barrier benefits.
๐ฌ Ingredient Breakdown
๐ Centella Asiatica Extract 39.2% Proven
The hero active in this formula and the highest-concentration ingredient. Centella Asiatica (also known as Cica or Gotu Kola) is a cornerstone of K-beauty for its multi-faceted skin-repair benefits. Rich in triterpenoid compounds including Asiaticoside, Madecassoside, Asiatic Acid, and Madecassic Acid, it actively supports barrier function restoration, collagen synthesis, and anti-inflammatory activity.
- Anti-inflammatory: Madecassoside inhibits pro-inflammatory cytokines and reduces skin redness at the cellular level.
- Barrier Repair: Stimulates keratinocyte proliferation and supports production of structural skin proteins.
- Antioxidant: Neutralizes free radicals from UV and environmental stressors that accelerate skin aging.
- Collagen Support: Asiaticoside and Asiatic Acid have been shown to stimulate fibroblast activity and collagen synthesis in clinical studies.
๐ Houttuynia Cordata Extract (Heartleaf) 28.1% Proven
Heartleaf is a traditional East Asian medicinal herb that has gained significant popularity in modern K-beauty for its ability to visibly calm heated, inflamed, and breakout-prone skin. At 28.1%, this is a meaningful active dose. Rich in amino acids, quercetin, and rutin, it works synergistically with Centella to reduce inflammatory response and balance natural oil production.
- Thermal Calming: Documented ability to lower skin surface temperature, reducing the appearance of flushing and heat-triggered redness.
- Antibacterial: Contains decanoyl acetaldehyde and other bioactive compounds with activity against acne-causing bacteria.
- Sebum Regulation: Helps balance excess sebum secretion, contributing to the formula's 29.9% oil-reduction clinical claim.
- Barrier Support: High amino acid content helps replenish and reinforce the skin's natural moisture barrier.
๐พ Glycyrrhiza Uralensis (Licorice) Root Extract 25.7% Proven
Licorice Root Extract is one of the most studied botanical ingredients in dermatology. At 25.7%, the concentration here is substantial. Its primary bioactive compounds โ Glycyrrhizin and Glabridin โ are renowned for their powerful anti-inflammatory, antioxidant, and mild brightening properties. It completes the triple-herbal complex by addressing redness, oxidative stress, and hyperpigmentation.
- Anti-Inflammatory: Glycyrrhizin has cortisone-like anti-inflammatory properties that soothe irritated skin without the side effects of topical steroids.
- Brightening: Glabridin inhibits melanin-stimulating enzymes, helping prevent post-acne dark spots and uneven tone over time.
- Antioxidant: Protects against UV-induced free radical damage, supporting long-term skin health.
- Redness Reduction: Clinical data supports licorice root's ability to visibly reduce redness associated with inflammatory skin conditions.
๐ง Glycerin + Betaine + Panthenol Supporting Actives Proven
The formula is further supported by a trio of proven humectants and skin-conditioning agents. Glycerin is one of the most effective hydrators known to science, drawing moisture to the upper skin layers. Betaine (from sugar beets) functions as both a humectant and an osmolyte, stabilizing skin cells against water loss and stress. Panthenol (Provitamin B5) penetrates deeper layers to support cell renewal and barrier recovery.
- Glycerin: Attracts water from deeper skin layers and the environment, proven to improve skin hydration significantly.
- Betaine: Naturally present in skin, helps regulate cellular water balance and supports a calmer-looking complexion.
- Panthenol: Converts to Pantothenic Acid in the skin, supporting tissue repair, hydration, and soothing of compromised skin.

๐ Where It Fits in Your Routine
Apply immediately after cleansing on damp skin as the first hydrating step. Use AM and PM. Can also be used as a multi-layer "7-skin" toning treatment for extra calming and hydration.
๐ How to Use
Cleanse Thoroughly
Start with a gentle, pH-balanced cleanser. Pat skin dry but leave slightly damp โ the toner absorbs beautifully into damp skin and helps lock in moisture more effectively.
Dispense & Apply
Pour a moderate amount (roughly a 10-cent coin size) into clean palms or onto a cotton pad. Shake the bottle gently first if product has been sitting.
Pat or Swipe onto Skin
Using your palms: gently press and pat the toner across your face and neck in an upward motion. Using a cotton pad: swipe gently in outward strokes following skin texture for light exfoliation.
Allow to Absorb
Let the toner absorb fully โ this typically takes 20โ30 seconds. It should leave skin feeling refreshed and balanced without any stickiness or residue.
Continue Routine
Follow with your essence, serum, and moisturizer. For an intensive calming treatment, layer 3โ7 thin applications (the "7-skin method") before moisturizing โ a popular K-beauty technique.
๐ค Who Is It For?
โ Perfect for you if:
- You have acne-prone, oily, or breakout-prone skin
- Your skin gets red, flushed, or inflamed easily
- You're dealing with post-acne marks and hyperpigmentation
- You want a lightweight first toner that won't feel heavy
- You're sensitive to fragrance and alcohol
- You're pregnant and need a safe, gentle toner
- You suffer from fungal acne and need FA-safe options
- You want a clean, minimal ingredient list with proven botanicals
โ Consider alternatives if:
- You need intense hydration for very dry or dehydrated skin (layer with a richer essence)
- You want strong exfoliating AHA/BHA toner action
- You expect noticeable brightening from the toner alone (niacinamide-based toners may be better)
- You are allergic to Centella Asiatica โ though rare, patch test first
- You prefer a completely scent-free formula (it has a faint natural herb scent)
๐ฏ Skin Type Compatibility
Clinically proven to reduce excess oil by 29.9% in 4 weeks. The watery, fast-absorbing formula adds zero greasiness and actively regulates sebum production via Heartleaf extract.
Specifically designed for breakout-prone skin. Reduces blackheads by 30.9%, whiteheads by 29%, and active breakouts by 46.3%. Non-comedogenic and fungal acne safe.
Fragrance-free, alcohol-free, and hypoallergenic. All three hero extracts have clinically documented anti-inflammatory properties. Redness reduced by 14.8% in clinical testing.
Balances skin beautifully across zones. Controls oiliness in the T-zone while the humectant blend keeps drier cheek areas hydrated and comfortable without overloading either area.
Glycerin, Betaine, and Panthenol provide solid hydration support. However, very dry skin types may want to layer with a richer essence or face oil afterward for additional moisture-sealing.

- Centella Asiatica, though rare, can cause reactions in those allergic to it

๐ฐ Budget-Friendly Alternatives (Dupes)
Also Centella Asiatica-focused and alcohol-free with a watery texture, but at a lower active concentration. No Heartleaf or Licorice Root. A solid budget option for Centella calming but lacks the triple-herbal synergy of the Numbuzin formula.
Features Heartleaf (Houttuynia Cordata) as the star ingredient at 77%, matching one of Numbuzin's three key actives. Great for oil control and redness, but lacks the Centella and Licorice components of the triple-extract blend. Slightly thicker consistency.
Centella-forward formula from the brand known for high-purity Madagascar Centella Asiatica. Calming and hydrating, but not specifically designed for oil control or blackhead reduction. A better match for dry-sensitive skin looking for calming without the sebum-control focus.

โ Frequently Asked Questions
Yes โ the Numbuzin No.1 Calming Herb Toner is considered safe for use during pregnancy and breastfeeding. The formula contains no retinoids (Retinol, Retinyl Palmitate, Tretinoin), no salicylic acid, no hydroquinone, and no chemical UV filters โ which are the main ingredients to avoid during pregnancy. All 18 ingredients are botanical extracts (Centella Asiatica, Heartleaf, Licorice Root), humectants (Glycerin, Betaine, Panthenol), and gentle solvents. As always, consult with your OB-GYN or dermatologist before adding any new skincare product to your routine during pregnancy.
Yes โ the Numbuzin No.1 Calming Herb Toner is fungal acne safe. The formula does not contain fermented ingredients, fatty acid esters, polysorbates, or oils โ the main ingredients that feed Malassezia yeast and can trigger fungal acne flare-ups. The 18-ingredient formula is entirely composed of botanical water-soluble extracts, polyol solvents, and skin-conditioning humectants, none of which are known to feed Malassezia. This makes it one of the better toner options for people managing fungal acne who still want calming and hydrating first-step care.
Yes โ this toner pairs well with most actives and can actually help minimize irritation when used before stronger treatments. The calming Centella Asiatica and Panthenol help soothe the skin before retinol or AHA/BHA application. Apply this toner first on clean skin, allow it to fully absorb, then apply your active serum or treatment. The low pH 5.5 also helps maintain the ideal pH environment for AHA/BHA exfoliants without disrupting their efficacy. For retinol, the Centella and Panthenol may help buffer the purging phase for sensitive skin types.
The Numbuzin No.1 Calming Herb Toner is officially recommended for all skin types, but it truly excels for oily, acne-prone, combination, and sensitive skin. The formula was specifically developed around three actives โ Centella Asiatica for repair, Heartleaf for oil control and temperature regulation, and Licorice Root for redness and antioxidant protection โ making it ideal for skin that is reactive, inflamed, congested, or prone to breakouts. Dry skin types can certainly use it, but may need to layer it with a richer essence or moisturizer for complete hydration, as the watery texture is more of a calming prep step than a deep moisture treatment.
Many users notice an immediate calming and cooling effect from the first application. For more measurable improvements: clinical testing shows redness reduced by 14.8% and active breakouts reduced by 46.3% within 2 weeks of twice-daily use. The 4-week clinical data shows oil reduction of 29.9%, blackhead reduction of 30.9%, and whitehead reduction of 29%. For longer-term benefits like barrier strengthening and fading of post-acne hyperpigmentation (supported by the Licorice Root and Centella Asiatica), consistent use over 2โ3 months will yield the most significant results.
The Numbuzin No.1 Calming Herb Toner is applied as the first hydrating step in your routine โ immediately after cleansing. The correct order is: Cleanser โ This Toner โ Essence (optional) โ Serum/Treatment โ Moisturizer โ Sunscreen (AM only). Being pH 5.5 and lightweight, it makes the ideal base layer that prepares skin to receive subsequent serums and treatments more effectively. For a concentrated treatment, try the 7-skin layering method: apply 3โ7 thin layers of this toner one at a time, patting each layer in before applying the next, before proceeding with the rest of your routine.
No โ the Numbuzin No.1 Calming Herb Toner is non-comedogenic with a comedogenic rating of 1 out of 5. The formula contains no oils, waxes, or high-comedogenic occlusives. The base is composed entirely of water-soluble botanical extracts, mild polyol solvents (Propanediol, Butylene Glycol, Dipropylene Glycol), and gentle skin-conditioning agents. The brand explicitly labels it non-comedogenic, and the ingredient composition confirms this. It is safe to use for acne-prone skin types and will not block or clog pores.
The Numbuzin No.1 Calming Herb Toner has a Period After Opening (PAO) of 12 months. Once opened, aim to use it within one year for optimal freshness and efficacy of the botanical extracts. The 100ml size typically lasts about 1โ2 months with twice-daily use. The 300ml size, which offers significantly better value per ml, typically lasts 3โ5 months depending on how generously you apply it. Store in a cool, dry location away from direct sunlight. Refrigerating the toner is optional but highly recommended by users to enhance the cooling, soothing sensation on application.
Verdict: The Numbuzin No.1 Pure-Full Calming Herb Toner is a standout in the crowded K-beauty toner market โ not because it promises everything, but because it delivers on its specific mission with remarkable focus and transparency. Replacing plain water with 93% triple-herbal extract at clinically meaningful concentrations (Centella 39.2%, Heartleaf 28.1%, Licorice Root 25.7%) is a genuine formulation achievement. The fact that efficacy is backed by published clinical data โ including 46.3% breakout reduction and 29.9% oil reduction โ makes this one of the most evidence-backed toners in its price range. Fragrance-free, fungal acne safe, pregnancy safe, and suitable for all skin types, it's an ideal first step for anyone with oily, reactive, or blemish-prone skin. If you want a clean, minimal, botanically potent toner that actually works, this is an exceptional choice.

Yes โ this toner pairs well with most actives and can actually help minimize irritation when used before stronger treatments. The calming Centella Asiatica and Panthenol help soothe the skin before retinol or AHA/BHA application. Apply this toner first on clean skin, allow it to fully absorb, then apply your active serum or treatment. The low pH 5.5 also helps maintain the ideal pH environment for AHA/BHA exfoliants without disrupting their efficacy. For retinol, the Centella and Panthenol may help buffer the purging phase for sensitive skin types.
The Numbuzin No.1 Calming Herb Toner is officially recommended for all skin types, but it truly excels for oily, acne-prone, combination, and sensitive skin. The formula was specifically developed around three actives โ Centella Asiatica for repair, Heartleaf for oil control and temperature regulation, and Licorice Root for redness and antioxidant protection โ making it ideal for skin that is reactive, inflamed, congested, or prone to breakouts. Dry skin types can certainly use it, but may need to layer it with a richer essence or moisturizer for complete hydration, as the watery texture is more of a calming prep step than a deep moisture treatment.
Many users notice an immediate calming and cooling effect from the first application. For more measurable improvements: clinical testing shows redness reduced by 14.8% and active breakouts reduced by 46.3% within 2 weeks of twice-daily use. The 4-week clinical data shows oil reduction of 29.9%, blackhead reduction of 30.9%, and whitehead reduction of 29%. For longer-term benefits like barrier strengthening and fading of post-acne hyperpigmentation (supported by the Licorice Root and Centella Asiatica), consistent use over 2โ3 months will yield the most significant results.
The Numbuzin No.1 Calming Herb Toner is applied as the first hydrating step in your routine โ immediately after cleansing. The correct order is: Cleanser โ This Toner โ Essence (optional) โ Serum/Treatment โ Moisturizer โ Sunscreen (AM only). Being pH 5.5 and lightweight, it makes the ideal base layer that prepares skin to receive subsequent serums and treatments more effectively. For a concentrated treatment, try the 7-skin layering method: apply 3โ7 thin layers of this toner one at a time, patting each layer in before applying the next, before proceeding with the rest of your routine.
No โ the Numbuzin No.1 Calming Herb Toner is non-comedogenic with a comedogenic rating of 1 out of 5. The formula contains no oils, waxes, or high-comedogenic occlusives. The base is composed entirely of water-soluble botanical extracts, mild polyol solvents (Propanediol, Butylene Glycol, Dipropylene Glycol), and gentle skin-conditioning agents. The brand explicitly labels it non-comedogenic, and the ingredient composition confirms this. It is safe to use for acne-prone skin types and will not block or clog pores.
The Numbuzin No.1 Calming Herb Toner has a Period After Opening (PAO) of 12 months. Once opened, aim to use it within one year for optimal freshness and efficacy of the botanical extracts. The 100ml size typically lasts about 1โ2 months with twice-daily use. The 300ml size, which offers significantly better value per ml, typically lasts 3โ5 months depending on how generously you apply it. Store in a cool, dry location away from direct sunlight. Refrigerating the toner is optional but highly recommended by users to enhance the cooling, soothing sensation on application.
Verdict: The Numbuzin No.1 Pure-Full Calming Herb Toner is a standout in the crowded K-beauty toner market โ not because it promises everything, but because it delivers on its specific mission with remarkable focus and transparency. Replacing plain water with 93% triple-herbal extract at clinically meaningful concentrations (Centella 39.2%, Heartleaf 28.1%, Licorice Root 25.7%) is a genuine formulation achievement. The fact that efficacy is backed by published clinical data โ including 46.3% breakout reduction and 29.9% oil reduction โ makes this one of the most evidence-backed toners in its price range. Fragrance-free, fungal acne safe, pregnancy safe, and suitable for all skin types, it's an ideal first step for anyone with oily, reactive, or blemish-prone skin. If you want a clean, minimal, botanically potent toner that actually works, this is an exceptional choice.
