Fungal Acne (Malassezia)

Not fungal acne safe. Contains PEG-60 Hydrogenated Castor Oil and Arginine, which may feed malassezia yeast when combined with skin lipids.

Sensitive Skin

Ingredient breakdown

INGREDIENTS

Willow Bark Water (Salix Alba) 88%Proven

The star ingredient and natural source of salicin, a precursor to salicylic acid. Acts as a gentle exfoliant with anti-inflammatory and antibacterial properties.

  • Function: Natural astringent that tightens pores and reduces inflammation
  • Research: Contains tannins with demonstrated antioxidant and antimicrobial effects
  • Benefit: Soothes irritated skin while providing mild exfoliation
Gentler than pure salicylic acid, making it ideal for daily use and sensitive skin types.

Betaine Salicylate 0.1%Proven

A mild BHA derivative combining betaine (from sugar beets) with salicylic acid. Provides gentle exfoliation without the harshness of traditional BHAs.

  • Function: Oil-soluble exfoliant that penetrates pores to dissolve sebum and debris
  • pH Range: Most effective at pH 3.8-4.2
  • Comparison: Less penetrating than salicylic acid, making it better for reactive skin
While gentler, still avoid use during pregnancy without consulting a healthcare provider.

Sodium HyaluronateProven

The sodium salt form of hyaluronic acid, a powerful humectant that can hold up to 1000x its weight in water.

  • Function: Attracts and retains moisture in the skin
  • Benefit: Prevents the drying effects sometimes associated with BHA products
  • Size: Smaller molecular weight allows for better skin penetration

Panthenol (Pro-Vitamin B5)Proven

A provitamin that converts to vitamin B5 in the skin, offering moisturizing and skin-barrier supporting benefits.

  • Function: Moisturizes, soothes inflammation, and supports wound healing
  • Research: Studies show it promotes fibroblast proliferation for skin repair
  • Benefit: Helps reduce irritation from other active ingredients

AllantoinProven

A naturally occurring compound found in comfrey root, known for its soothing and skin-conditioning properties.

  • Function: Calms irritation, promotes cell regeneration, and softens skin
  • Benefit: Helps balance the exfoliating effects of BHA

Frequently asked questions

FAQ

Use with caution. This product contains Betaine Salicylate (a BHA derivative) and Willow Bark Water, which are related to salicylic acid. While the concentration is very low (0.1%), it's recommended to consult your healthcare provider before use during pregnancy or breastfeeding. Many dermatologists advise avoiding BHA products during pregnancy as a precaution.

No, this product is not fungal acne safe. It contains PEG-60 Hydrogenated Castor Oil and Arginine, which can feed malassezia yeast when combined with skin's natural lipids. If you have fungal acne, look for products specifically formulated to be malassezia-safe.

Yes! Due to its very low BHA concentration (0.1%), this product can safely be layered with other acids like AHA, BHA, and even vitamin C. COSRX specifically designed it to complement other exfoliating products. However, always introduce new combinations gradually and monitor your skin for irritation. If using retinol, consider using this product in the morning and retinol at night.

This product works best for oily and combination skin types dealing with enlarged pores and excess sebum. It's also excellent for sensitive skin that cannot tolerate stronger BHA products. It's suitable for beginners to chemical exfoliation. Those with severe acne may find the 0.1% concentration too mild and should consider stronger alternatives.

Initial texture improvement can be felt within 1-2 weeks of consistent use. More noticeable pore refinement and sebum control typically appear after 3-4 weeks. Significant visible results in pore minimization usually require 6-8 weeks of daily use. This is a gradual, gentle product — patience is key for best results.

Apply after cleansing and toning, before serums and moisturizer. Use as a treatment essence step. In the morning, follow with moisturizer and sunscreen. You can also use it as a mask by soaking cotton pads and leaving on enlarged pore areas for 5-10 minutes. It can be used both AM and PM.

This product has a low comedogenic rating of approximately 1/5. The lightweight, watery formula is specifically designed to help clear pores rather than clog them. The BHA and willow bark actually help dissolve pore-clogging sebum and debris. However, individual reactions vary, so patch testing is always recommended.

The product has a PAO (Period After Opening) of 12 months. Store in a cool, dry place away from direct sunlight to maintain efficacy. The pump bottle helps minimize air exposure and contamination. With daily use of 2-3 pumps, a 100ml bottle typically lasts 2-3 months.

— Skincarisma verdict
4.2 / 5 ★★★★☆

Verdict: The COSRX Two In One Poreless Power Liquid is an excellent entry-level BHA treatment for those seeking gentle pore refinement without irritation. Its 88% willow bark water base combined with 0.1% betaine salicylate makes it one of the mildest BHA products on the market — perfect for sensitive skin and acid beginners. While too gentle for stubborn acne or deep blackheads, it excels at daily maintenance, sebum control, and skin smoothing. The cooling sensation is a bonus for hot climates. Not suitable for fungal acne sufferers or those needing aggressive exfoliation, but a solid choice for anyone wanting to dip their toes into chemical exfoliation or maintain already-clear pores.

question
lightbulb What are Notable Effects & Ingredients?

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.

muscle Pro Tip Alert!

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

question
lightbulb What is the Ingredient Safety Breakdown?

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.

muscle Pro Tip Alert!

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.
