This liquid exfoliant is a cult-favorite for those struggling with blackheads, enlarged pores, and oily skin. [cite_start]It uses a gentle form of BHA to clear out pores, control sebum, and improve skin texture, leaving you with a smoother, clearer complexion[cite: 1994, 2030].

Best for: Oily, combination, and acne-prone skin types with blackheads and congested pores[cite: 1994, 2033]. It is also suitable for mid-level acid users.

Beginner Note: Start slowly to allow your skin to adjust to chemical exfoliation. [cite_start]You may notice an initial period of purging as it works to clear clogged pores[cite: 2035, 1994].

For a beginner-friendly evening routine, you can integrate this product into your existing regimen:

• [cite_start]
• 1) Cleanser — use a gentle cleanser to start with a clean base[cite: 2035].
• [cite_start]
• 2) This product — apply a thin layer to congested areas[cite: 2035].
• [cite_start]
• 3) Moisturiser — follow with a simple, non-comedogenic moisturizer to seal in hydration[cite: 2035].

Note: Already own a similar step? Finish that first (substitute, don’t stack).

This product is recommended for evening use due to its exfoliating nature. [cite_start]Your morning routine should focus on cleansing, hydrating, and protecting your skin from the sun[cite: 2035].

• 1) Cleanser — quick wash; clean base.
• 2) Hydrating Toner/Essence (optional; adds slip) → 3) Moisturiser — seal & protect.
• [cite_start]
• 3) Sunscreen SPF 30+ — always the last step[cite: 2035].

This product is an exfoliant, so it's recommended for use in your evening routine.

• 1) Cleanser (double-cleanse if makeup/water-resistant SPF: oil → water) — thoroughly wash away makeup, sunscreen, and daily grime.
• [cite_start]
• 2) This product — see amount in “How to Use”[cite: 2035].
• 3) Moisturiser/Oil — lock in hydration with a lightweight moisturizer to prevent dryness.

Note: Do not use other strong actives (like retinoids or other acids) on the same night[cite: 2036, 1994].

Daily Use — PM only:

• [cite_start]
• Amount: 1–2 pumps for the entire face[cite: 2035].
• Apply to: Your face and neck, focusing on congested areas like the T-zone and chin. [cite_start]Avoid the lip and eye area[cite: 2035].
• [cite_start]
• Method: After cleansing, dispense the liquid onto a cotton pad and gently swipe a thin layer over the skin, or use your fingers to pat it in[cite: 2035].
• Frequency: Begin by using it once a week, then gradually increase to 2–3 times per week as your skin adapts. [cite_start]Do not use this with other highly concentrated AHA, BHA, or Vitamin C products[cite: 2035].
• Wait times: Allow the liquid to be fully absorbed before applying your next skincare product. Waiting for about 20 minutes before the next step may yield better results.

Dosage quick-table:

• [cite_start]
• Serum/Essence: 1–2 pumps[cite: 2035].

If-This / Then-That:

• Very oily T-zone? [cite_start]Focus application on the T-zone and chin to help control excess oil and clear blackheads[cite: 2033].
• Sensitive/reactive? [cite_start]Start with once a week and ensure you moisturize well afterward[cite: 2033].

Watchouts: Pilling = not an issue with this product's texture; sensitivity = can be caused by overuse or using other strong actives[cite: 2036]. You may experience purging in the first weeks of use. [cite_start]Patch test advised for all new products[cite: 2040].

Safety: Do not use on damaged or broken skin. Stop if burning rash. [cite_start]Do not use if you are allergic to aspirin[cite: 2040]. Teens: start with a very low frequency (once a week) and always follow with a hydrating, gentle moisturizer and daily sunscreen.

Example week (PM focus): Mon Soothing night (no strong actives) · Tue This Product (BHA) · Wed Soothing night · Thu Soothing night · Fri This Product (BHA) · Sat Soothing night · Sun Off.

Rules: One strong active per night. [cite_start]Do not use strong retinoids and strong acids on the same night[cite: 2036].

PM/AM cheat-sheet: AHA/BHA/PHA PM 1–3×/week; Retinal/Retinol PM 2–4×/week; Vitamin C AM daily; Niacinamide AM/PM (safe to use on non-active nights to support the barrier).

Mauritius note: In heat/humidity, keep layers thin. Hydrating SPF may replace AM moisturizer.

Safety: If irritation occurs, reduce frequency to 2×/week, switch to soothing nights, and follow patch-test guidance.

Immediate: Skin may feel smoother and appear refreshed the next day. Some users report a slight tingling sensation upon application. [cite_start]Some may experience an initial purge (small breakouts in problem areas) that lasts for a few weeks[cite: 2017, 2030].

2–4 weeks: You may notice a reduction in sebaceous filaments (blackheads) and an improvement in skin texture[cite: 2030]. Oily areas may feel less shiny as sebum production begins to normalize. [cite_start]Blackheads on the nose, chin, and cheeks may start to diminish, and pores may appear cleaner and smaller[cite: 2030]. Some users report that bumps and blockages become less prominent.

4–8+ weeks: With consistent use, blackheads should be visibly reduced, and your skin should appear smoother and brighter. [cite_start]The product can also help fade post-acne marks and keep new breakouts at bay[cite: 2030]. Pores and sebaceous filaments will be noticeably minimized. Patience is key for long-term results.

• [cite_start]
• Exfoliants: This uses a gentle BHA exfoliant to safely clear out pores, unlike harsh scrubs that can cause micro-tears and worsen breakouts[cite: 2030].
• [cite_start]
• Cleansing: This product helps remove excess sebum and debris without the need for over-cleansing or harsh stripping soaps that can damage the skin barrier and lead to more oil production[cite: 1458, 2030].

Works with:

• [cite_start]
• Niacinamide: Pairs well to reduce sebum and improve skin barrier health[cite: 1464, 1994, 2036].
• Moisturizers: Use a lightweight, hydrating moisturizer after this product to prevent dryness and support the skin barrier.
• [cite_start]
• Sunscreen: Must be used daily when incorporating any chemical exfoliant to prevent sun damage and potential irritation[cite: 1450, 1475].

Use carefully:

• [cite_start]
• Vitamin C: Use on a different night, or at a different time of day, as combining exfoliants with pure vitamin C can be too irritating[cite: 1473, 2036].
• [cite_start]
• Peptides: While not a direct conflict, layering with strong acids may reduce peptide efficacy[cite: 1471].

Avoid on same night:

• Retinoids (Retinol, Retinal): Combining with BHA can lead to over-exfoliation, irritation, and a damaged skin barrier. [cite_start]Alternate nights for best results[cite: 1473, 2036].
• [cite_start]
• Other strong acids (AHA/BHA/PHA): Avoid layering with other strong exfoliants in the same routine to prevent irritation[cite: 1473].

Key Actives Explained:

• [cite_start]
• Betaine Salicylate (4%): A gentle exfoliant and keratolytic agent that clears clogged pores by dissolving excess sebum and dead skin cells[cite: 1468, 1994]. [cite_start]It's a milder form of salicylic acid that works deep within the pores[cite: 1468, 1994].
• Salix Alba (Willow) Bark Water (68%): A natural alternative to purified water that contains anti-inflammatory salicylates, a close relative of salicylic acid. [cite_start]It has soothing, astringent, and antiseptic properties[cite: 1994].
• [cite_start]
• Arginine: An amino acid that helps hydrate and strengthen the skin barrier while also helping to soothe potential irritation from exfoliants[cite: 1994].
• [cite_start]
• Sodium Hyaluronate: A form of hyaluronic acid that attracts and binds moisture to the skin, helping to keep it hydrated and plump after exfoliation[cite: 1467].

Full INCI: Salix Alba (Willow) Bark Water, Butylene Glycol, Betaine Salicylate, Niacinamide, 1,2-Hexanediol, Arginine, Panthenol, Xanthan Gum, Ethyl Hexanediol, Allantoin, Sodium Hyaluronate[cite: 1994].

Fragrance Status: Fragrance-free[cite: 1994]. This product has a natural, mild scent from the ingredients themselves.

EU Allergens: The brand has not declared any of the 26 EU allergens[cite: 1994].

Who should use with caution: Individuals with very sensitive skin and those who are allergic to aspirin[cite: 2040]. [cite_start]Do not use if you are pregnant or breastfeeding as a precaution[cite: 2048, 1994].

Patch test protocol: Apply a small, pea-sized amount of the product to a discreet area like your jawline or behind your ear. Assess the area after 24–48 hours for any signs of redness, itching, or irritation. Re-check the area again at 72 hours. [cite_start]If any burning or rash occurs, discontinue use immediately[cite: 2040].

Teens: This product can be used by teens but should be introduced slowly and at a lower frequency to prevent irritation[cite: 1994]. Ensure a consistent routine of gentle cleansing, moisturization, and daily SPF.

Texture: A watery, lightweight liquid that absorbs quickly into the skin[cite: 2017, 1994].

pH: The formula is at a pH of around 4.0, which is ideal for BHA to exfoliate effectively[cite: 1475].

This product is an excellent choice for Mauritius’s humid climate. [cite_start]It helps manage the excess sebum and sweat that can lead to clogged pores, making it ideal for the hot, sticky weather[cite: 1458, 1994]. Due to its lightweight texture, it absorbs quickly and won't feel heavy on your skin. [cite_start]BHA is a great option for keeping your pores clean, which is a major skincare goal in a humid, tropical environment[cite: 1450, 1994].

This product uses Betaine Salicylate as its primary active ingredient. [cite_start]This is a gentle BHA exfoliant that works to clear pores and reduce inflammation[cite: 1468, 1994]. [cite_start]Willow bark water contains natural salicylates to soothe the skin[cite: 1994]. [cite_start]Niacinamide helps with sebum regulation and post-acne marks[cite: 1464]. [cite_start]The inclusion of Panthenol and Sodium Hyaluronate helps to maintain a healthy skin barrier and prevent dehydration that can sometimes result from exfoliation[cite: 1467, 1466]. [cite_start]The product’s effectiveness is supported by in-house clinical tests that demonstrate its ability to reduce blackheads and sebum[cite: 1994].

Based on a 1-2 pump dosage used 2-3 times per week, one 100ml bottle should last for several months. For a beginner using it twice per week, it would last approximately 8-10 months, so a reorder would likely be needed annually. For more frequent use (4 times a week) it may last closer to 4-5 months.
