Numbuzin Zero Blemish Clarifying 2% Sulfur Cleansing Foam 150ml

This product contains Salicylic Acid at an undisclosed concentration alongside Colloidal Sulfur. While it is a brief-contact, rinse-off cleanser (which reduces exposure compared to a leave-on product), the brand has not published the exact Salicylic Acid percentage. If you are pregnant, planning to become pregnant, or breastfeeding, consult your doctor before using this product, since the concentration cannot be independently confirmed as low-risk.

Values: 100% Genuine · Not independently confirmed Fragrance-Free.

Pros: a genuine, brand-disclosed 2% Sulfur dose, Centella buffering, amino-acid surfactant base rather than a harsh soap. Caveats: exact Salicylic Acid % not disclosed, full INCI only partially retrievable this pass, pH not disclosed.

Acne-prone skin in Mauritius heat often gets over-washed out of frustration, which strips the acid mantle (target pH 4.5-5.5) and triggers compensatory sebum — the exact oiliness that fuels more breakouts. This cleanser's amino-acid surfactants (Sodium Cocoyl Glycinate, Coco-Glucoside) are gentler than a harsh soap base, so twice-daily use should feel comfortable, not tight or squeaky.

Step 1 (When): AM and PM. Step 2 (How much): A coin-size amount, worked into a light lather. Step 3 (How): Massage for the full 60-second surfactant contact time, then rinse.

Introduce this as the ONLY new product in your routine. Wait a full 14 days before adding anything else.

1. This cleanser. 2. Toner. 3. Serum/treatment. 4. Moisturizer. 5. Sunscreen SPF50+ PA++++.

This is an encyclopedia map of all product types. You do not use all of these daily. You select modules based on your skin state.

Global rules: viscosity ladder thinnest to thickest, water-phase before oil-phase, treatments before seals.

AM Maximum Stack: Rinse/Gentle Cleanse (this product) → pH-Prep Toner (optional) → Oil-Control/Sebum-Regulating Lane → Moisturizer → Sunscreen SPF50+ PA++++ (non-negotiable).

PM Maximum Stack: Oil Cleanser (if makeup/SPF) → Water Cleanser (this product) → Toner → Anchor treatment → Moisturizer. Do not layer this cleanser's BHA with a separate leave-on acid exfoliant the same night without spacing them out.

One-lane rule: Retinoid OR Exfoliation OR Strong Vitamin C OR Acne-control active per routine; barrier/hydration can always accompany.

As a rinse-off product, this sits outside the leave-on layering ladder — applied first, rinsed fully away before any treatment step.

Purging vs. Reaction: purging occurs in usual breakout areas, is surface-level, and resolves in 4-6 weeks; a reaction (stop immediately) occurs in new areas, involves burning/swelling/hives, and worsens without improvement.

Breakouts/excess oil: Colloidal Sulfur has antimicrobial and oil-absorbing properties; Salicylic Acid and PHA (Gluconolactone) help clear follicle debris. Redness: Centella Asiatica Leaf Extract offers calming support.

What this product cannot do: a cleanser's brief contact time cannot replace a leave-on spot treatment for active, inflamed lesions — pair with a targeted product for existing breakouts.

Same-line spot treatment — primary pick: Numbuzin Zero Blemish 3X Spot Correcting Cream. Alternatives: Numbuzin Zero Blemish Azela Cica Balancing Dual Pads, Numbuzin Zero Blemish Oil-Free Micellar Cleansing Jelly (as a gentler first-cleanse pairing).

Morning seal — primary pick: Numbuzin No.1 Clear Filter Sun Essence SPF50+ PA++++. Alternatives: SKIN1004 Madagascar Centella Air-Fit Suncream Light, Beauty of Joseon Relief Sun: Rice + Probiotics.

MYTH: "Sulfur cleansers smell bad because they're not properly formulated." REALITY: Colloidal Sulfur can carry a faint sulfurous note in some formulas; this is a normal characteristic of the ingredient, not a spoilage sign, though the exact scent profile of this SKU was not independently confirmed this pass.

Mauritius tap water hardness varies by region; follow with a pH-balancing toner to counteract any calcium-stearate residue from the rinse-off step.

Partial INCI (full ordered list not retrievable this pass): Water, Glycerin, Sodium Cocoyl Glycinate, Lauryl Hydroxysultaine, Colloidal Sulfur, Gluconolactone, Centella Asiatica Leaf Extract, Zea Mays Starch, Cynanchum Atratum Extract, Althaea Rosea Flower Extract, Coco-Glucoside, Sodium Chloride, Hectorite, Hydroxypropyl Starch Phosphate, and additional ingredients (including Salicylic Acid and any preservative system) not captured in exact order this pass. Full ingredient list beyond this point not publicly disclosed by the brand at the time of writing.

Fragrance status: Not independently confirmed either way this pass. EU 26 allergen screen: not assessable from the partial INCI retrieved. Patch test advised given the sulfur/BHA combination regardless of fragrance status.

Halal: *Self-assessed by Adilsons based on available INCI data. No ethanol or haram animal-derived ingredients detected in the partial declared list. This is NOT a formal Halal certification — the incomplete INCI makes this a lower-confidence assessment than usual. Muslims with stricter requirements should consult their own scholars.

Vegan: *Self-assessed based on available (partial) INCI data. No animal-derived ingredients detected in what was retrieved. This is NOT a formal vegan certification — brand marketing separately describes this product as vegan.

Cruelty-free: the brand states this product is skin-irritation tested and antimicrobial/antifungal; *not independently certified by Leaping Bunny, PETA, or equivalent third-party audit.

MFDS classification: Not independently confirmed as Functional. Clinical claim: the brand states clinical testing showed reductions in inflammatory and non-inflammatory acne, but no institution, sample size, or date range was found this pass. Evidence confidence: Marketing-Only* for that claim. *Unpublished, brand-commissioned figure; treat as marketing-only pending a citable primary source.

Assessment: None — rinse-off product, no leave-on layering.

Store away from direct heat. A strong, unusually sharp sulfurous or sour smell beyond the ingredient's normal mild note, or a texture change, signals it should be discarded.

Patch test on the inner forearm for 24 hours before first face use, given the sulfur + undisclosed-concentration BHA combination. If adverse reaction occurs: stop all actives, use only a gentle cleanser and plain moisturizer for 72 hours, then reintroduce one product per 14 days. Seek emergency care for hives, swelling, blistering, persistent burning, or breathing difficulty.

1) Using it as a leave-on mask rather than a rinse-off cleanser. 2) Skipping moisturizer after, assuming acne-prone skin doesn't need it. 3) Combining with a separate leave-on strong exfoliant the same day without monitoring for over-exfoliation. 4) Ignoring persistent dryness as "purging." 5) Using it more than twice daily hoping for faster results.

At a coin-size amount twice daily, a 150ml bottle lasts approximately 2 months. Reorder about two weeks before you expect to run out.

Use as your primary or second cleanse, AM and PM, with a full 60-second lather-and-massage before rinsing.

If you are pregnant or nursing, consult your doctor first given the undisclosed BHA concentration. If your skin feels dry after a week, reduce to once daily and add a barrier-support moisturizer.

If you want a BHA cleanser with a brand-disclosed concentration, SKIN1004 Madagascar Centella Tea-Trica BHA Foam is a verified in-stock alternative. Further alternatives: Anua Heartleaf Succinic Cleansing Foam (0.5% Succinic Acid, brand-disclosed), SKIN1004 Madagascar Centella Poremizing Deep Cleansing Foam.

Choose this cleanser over the SKIN1004 BHA Foam if you specifically want the added Sulfur + PHA combination for stubborn, sulfur-responsive breakouts — sulfur has an antimicrobial mechanism distinct from BHA alone.

If you want a disclosed BHA %, the SKIN1004 option is worth it. If you specifically want sulfur's antimicrobial action alongside BHA, this numbuzin cleanser is the more targeted pick — but confirm you are comfortable with an undisclosed BHA concentration first.

This product's PRIMARY function is: acne-focused rinse-off cleanse. You do NOT need this if you already own a working BHA or sulfur cleanser — finish that one first.

This product is sourced through authorized Korean distributors — primarily Craver Co., Ltd (South Korea), alongside other verified distribution partners. Craver is a major Korean beauty distributor and the parent company of SKIN1004, handling authorized distribution for multiple K-beauty brands. All products are shipped directly to Mauritius via verified channels.

numbuzin is a South Korean skincare brand founded in 2019. The Zero Blemish line (also called "No.0" on the brand's own US site) is a newer, dedicated acne-care range distinct from the brand's numbered No.1-No.9 product lines, and shows a genuinely concentration-consistent formulation pattern for its headline actives.

Community reviews for this exact SKU were limited in our research at the time of writing, as it is a newly-added line. Available retailer commentary described the Sulfur/BHA/PHA combination positively for acne-prone skin, paraphrased rather than quoted. No dedicated Reddit thread was found.

What is the exact Salicylic Acid percentage? Not publicly disclosed by the brand at the time of writing.

Is this safe during pregnancy? Consult your doctor — the undisclosed BHA concentration cannot be independently confirmed as low-risk, even though it is a rinse-off product.

Can I use this twice daily? Yes, as designed, though reduce to once daily if dryness appears.

Does it smell like sulfur? Sulfur-based cleansers commonly carry a faint characteristic note; this SKU's exact scent profile was not independently confirmed this pass.
