Texture & feel
SENSORYDeep Pore Cleansing
Oil-soluble BHA penetrates deep into pores to dissolve sebum, dead skin cells, and impurities that cause blackheads and breakouts.
Antioxidant Protection
Resveratrol from red grapes and EGCG from green tea neutralize free radicals and protect against UV-induced skin damage and premature aging.
Hydrating Formula
Sodium PCA, a natural moisturizing factor, locks in hydration while the BHA exfoliates, preventing the dryness often associated with acid treatments.
Optimal pH Level
Formulated at pH 3.8 for maximum BHA efficacy while remaining gentle enough for sensitive skin when used as directed.
Safety & compatibility
SAFENot recommended. Contains 2% Salicylic Acid which should be avoided during pregnancy and breastfeeding per brand guidelines.
Not FA-safe. Contains Leuconostoc/Radish Root Ferment Filtrate which may feed Malassezia yeast.
Rating 0/5. No pore-clogging oils or heavy emollients. Safe for acne-prone skin.
BHA increases photosensitivity. Always use SPF 30+ during the day when using this product.
Avoid if allergic to aspirin (acetylsalicylate). Salicylic acid is chemically related to aspirin.
Start with 1x per week and gradually increase. pH 3.8 is effective but may cause initial tingling.
Ingredient breakdown
INGREDIENTSSalicylic Acid 2%Gold Standard
The star ingredient. This oil-soluble BHA penetrates deep into pores to dissolve sebum plugs, exfoliate inside the pore lining, and reduce inflammation associated with acne.
- FDA Approved: 0.5-2% concentration recognized for OTC acne treatment
- Clinical Evidence: Reduces blackheads and whiteheads within 1-2 weeks of consistent use
- Anti-inflammatory: Structurally similar to aspirin, calms redness and irritation
ResveratrolProven Antioxidant
The "red wine antioxidant" derived from grape skins. Provides powerful protection against oxidative stress and environmental damage while supporting skin's natural repair processes.
- Research: Strong antioxidant, anti-inflammatory, and anti-aging properties documented in dermatological studies
- UV Protection: Helps protect against UV-induced damage when used with sunscreen
Epigallocatechin Gallate (EGCG)Proven Antioxidant
The primary polyphenol in green tea, EGCG is one of the most studied antioxidants in skincare with documented anti-inflammatory and sebum-regulating properties.
- Sebum Control: Studies show EGCG can reduce sebum production in oily skin
- Anti-acne: Antibacterial properties help combat acne-causing bacteria
- Photoprotection: Provides additional defense against UV damage
Sodium PCASkin-Identical
A naturally occurring component of human skin's Natural Moisturizing Factor (NMF). Attracts and binds water to keep skin hydrated even during exfoliation.
- Humectant: Highly effective moisture-binding ingredient
- Comedogenic Rating: 0 - will not clog pores
- Irritancy: 0 - extremely well tolerated
Succinic AcidPromising
A naturally occurring acid with antimicrobial and anti-inflammatory properties. Works synergistically with BHA to combat acne and support elastin production.
- Antimicrobial: Helps fight acne-causing bacteria
- Elastin Support: May help maintain skin elasticity
Superoxide Dismutase (SOD)Proven Antioxidant
A powerful enzyme that neutralizes superoxide radicals - one of the most damaging forms of free radicals. Supports skin's natural defense mechanisms.
- Antioxidant: Breaks down radical molecules into harmless oxygen and hydrogen peroxide
- Anti-inflammatory: Helps reduce chronic inflammation

Where it fits in your routine
ROUTINEApply immediately after cleansing on dry skin. No cotton pad needed - dispense into palm and pat onto face. Wait for absorption before next step.
How to use
HOW TO USEStart Slowly
Begin with 1x per week application. Gradually increase to up to 4x weekly as your skin adjusts to the exfoliation.
Apply to Clean Skin
After cleansing, dispense a small amount into your palm (no cotton pad needed) and gently pat onto dry skin, avoiding eye area.
Let It Absorb
Allow the product to fully absorb before applying subsequent skincare products. This typically takes 30-60 seconds.
Follow with Sunscreen
Always apply SPF 30+ during the day. BHA increases sun sensitivity - sunscreen is essential to prevent UV damage.

- Can cause initial purging period
- May be too drying for very dry skin types
- Limited international availability
- Requires sunscreen use (increases photosensitivity)
- Plain packaging compared to luxury competitors
Budget-friendly alternatives (dupes)
DUPESThe gold standard BHA. Contains 2% salicylic acid with green tea. More expensive but clinically tested with cult following. Simpler formula without ferments - fungal acne safe option.
Uses 4% Betaine Salicylate (gentler BHA derivative) instead of pure salicylic acid. Contains Niacinamide for additional brightening. Higher pH (4.85) makes it gentler but potentially less effective.
Most affordable option with same 2% concentration. Very basic formula without antioxidants. Discontinued and relaunched - availability may vary. No-frills approach to BHA exfoliation.
German drugstore alternative with 2% BHA. Even more affordable but simpler formula. Good entry-level BHA for those new to chemical exfoliation. Different ingredient approach.

Frequently asked questions
FAQNo. The brand explicitly recommends avoiding this product during pregnancy and breastfeeding due to the 2% Salicylic Acid content. While topical salicylic acid in low concentrations is considered low risk by some sources, it's best to err on the side of caution. Consider AHA alternatives like lactic acid or switch to purely hydrating products during this time.
No. This product contains Leuconostoc/Radish Root Ferment Filtrate, which is a ferment that can potentially feed Malassezia yeast. If you have fungal acne, consider Paula's Choice BHA (though it contains Polysorbate 20) or COSRX BHA Blackhead Power Liquid which is fungal acne safe.
Use caution when combining acids. Avoid using Liquid Refiner on the same day as retinol, AHAs, or other BHAs to prevent over-exfoliation. Vitamin C can be used in a different routine (morning vs. evening). Always introduce new actives slowly and monitor your skin's reaction. A good approach is alternating nights between this BHA and retinol.
This product is best suited for oily, combination, and acne-prone skin types. The BHA penetrates oil to unclog pores and regulate sebum. It's also suitable for sensitive skin when used sparingly (start 1x weekly). Those with dry skin should use with caution and always follow with a rich moisturizer.
Most users notice smoother skin texture within 1-2 weeks. Visible reduction in blackheads typically occurs by weeks 3-4. Full results including pore refinement and clearer skin are usually achieved within 6-8 weeks of consistent use. Note that some initial purging may occur in the first 2-3 weeks as clogged pores clear.
Apply immediately after cleansing on dry skin, before any toners, serums, or moisturizers. No cotton pad is needed - dispense a small amount into your palm and pat onto skin. Wait for it to absorb (30-60 seconds) before continuing with the rest of your routine. Always finish with sunscreen during the day.
No, this product has a comedogenic rating of 0/5. It contains no pore-clogging oils or heavy emollients. In fact, the 2% BHA actively works to unclog pores and prevent future congestion. It's specifically designed to clear pores, not clog them.
The product has a 12-month PAO (Period After Opening). The 100ml bottle typically lasts 2-4 months with regular use (3-4x weekly). Store in a cool, dry place away from direct sunlight to maintain efficacy. The opaque bottle helps protect light-sensitive ingredients like Resveratrol.
Verdict: The Nø Cosmetics Liquid Refiner delivers impressive results at a fraction of the cost of premium BHA treatments. With its effective 2% Salicylic Acid, optimal pH 3.8, and bonus antioxidants (Resveratrol, EGCG, SOD), it offers excellent value for oily and acne-prone skin. The clean, fragrance-free formula is well-tolerated by most skin types. However, the inclusion of ferment filtrate makes it unsuitable for fungal acne sufferers, and it's not safe for pregnancy. If you're looking for a budget-conscious BHA that punches above its weight class, this German gem deserves a spot in your routine.
Product Overview
Quick product notes are a great way to check if a product is free from commonly avoided ingredients by skincare enthusiasts. These preferences come about for different reasons depending on the ingredient such as personal experiences, sensitivities, health preferences & etc.
Just because a product is not free from a common preference does not mean it's a bad product! You can make a personal decision whether or not you want to use a product that contains these ingredients or not - click the labels of the preference to read more about them.
Quick Product Notes
Ever used a product that promised a certain effect but provided no results? It might not have contained any notable ingredients that could have been responsible for that promised effect. It doesn't matter what the marketing or packaging «promises» it can do, if it doesn't contain anything that can help - then the likelihood of it helping is low.
We help you identify key notable ingredients that have been shown to help with effects such as acne-fighting, brightening, UV-protection, wound healing & anti-aging to help you achieve your skincare goals smarter. Please note that different notable ingredients have varying levels of research behind them, some are extremely well proven yet some have mixed research in their efficacy.
Just because a product doesn't contain any notable ingredients doesn't mean it's bad. And a product with notable ingredients (or even many) doesn't necessarily guarantee the efficacy of the product performing these effects either. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine this.
Be smart and use this as just a starting point for you to make more informed and smarter choices and compare it with reviews to see if the product is right for you
Notable Effects & Ingredients
Why are some products great for some people and horrible for others? Well everyone has different skin types and different reactions to the same ingredients.
We've identified a range of ingredients that are commonly regarded as potentially good or bad for those with Dry, Oily/Acne-Prone or Sensitive skin.
A product that contains good or bad ingredients for your skin type doesn't always flat out make the entire product good or bad for your skin. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine your skins reaction.
One of the best ways to use this section is to troubleshoot products you've had bad experiences with in the past. Check if it contains any of the marked ingredients to point out suspect ingredients to avoid in the future!
Ingredients Related to Skin Types
Ingredient Safety Breakdown refers to the percentage % of ingredients in different risk categories as classified by EWG (Environment Working Group) if they are available. There are almost endless cosmetic ingredients and they are one of the few organisations globally that have assigned ratings to a lot of the more commonly used ingredients which is why we reference them.
EWG is seen by many to be more on the alarmist side in their assignment of health ratings resulting in rating ingredients as riskier than they actually are. We recommend using this a reference point rather than a strict guide of ingredient safety and to always do further research if into ingredients that you may find suspect.
