Acne Treatment + Prevention

Fights existing breakouts while preventing new ones by controlling excess sebum and keeping pores clear.

02

Safety & compatibility

SAFE
Pregnancy & Breastfeeding

Contains 0.5% Salicylic Acid. While topical SA under 2% in rinse-off products is generally considered safe, consult your healthcare provider before use during pregnancy.

Fungal Acne (Malassezia)

NOT safe for fungal acne. Contains multiple fatty acids (Stearic, Myristic, Palmitic, Lauric, Oleic, Arachidic Acid) that can feed Malassezia yeast.

Non-Comedogenic

Dermatologist tested and formulated to not clog pores. Comedogenic rating of 1/5 - very low risk of causing breakouts from pore blockage.

Sensitive Skin Friendly

Hypoallergenic formula clinically tested for skin irritation. Free from artificial fragrance, parabens, and sulfates.

Ingredient breakdown

INGREDIENTS

Salicylic Acid 0.5%Proven

A beta-hydroxy acid (BHA) that penetrates oil to exfoliate inside pores, dissolve dead skin cells, and reduce inflammation. The gold standard for treating acne, blackheads, and whiteheads.

  • FDA Approved: Concentrations of 0.5-2% are recognized as OTC topical acne treatments
  • Oil-Soluble: Penetrates sebum to clean deep within pores
  • Anti-Inflammatory: Related to aspirin, helps calm redness and swelling

CentellAC-RX Complex ProprietaryProven

COSRX's signature blend of three active compounds from Centella Asiatica: Madecassic Acid, Asiaticoside, and Asiatic Acid. Known for wound healing, anti-inflammatory, and skin barrier repair properties.

  • Madecassic Acid: Promotes collagen synthesis and wound healing
  • Asiaticoside: Potent anti-inflammatory and antioxidant
  • Asiatic Acid: Strengthens skin barrier and reduces scarring
Centella compounds help counteract potential irritation from Salicylic Acid, making this cleanser gentler than typical acne cleansers.

Glycerin HighProven

A powerful humectant that draws moisture into the skin. Second ingredient on the list, indicating a significant concentration to help maintain hydration during cleansing.

  • Research: Studies show glycerin is more effective as a humectant than hyaluronic acid
  • Barrier Support: Helps maintain skin's moisture barrier during cleansing

Lavandula Hybrida Oil LowSupportive

Natural lavender essential oil that provides the product's subtle herbal scent. Also offers mild antibacterial and calming properties.

Contains Linalool and Limonene (natural fragrance components). May cause sensitivity in those allergic to essential oils.

24 ingredients

How to use

HOW TO USE
1

Wet Your Face

Splash your face with lukewarm water. Avoid hot water as it can strip natural oils and irritate acne-prone skin.

2

Dispense & Lather

Squeeze a small amount (about a cherry-sized dollop) onto your palm. Add a little water and work into a rich, creamy foam.

3

Massage Gently

Apply the foam to your face using gentle, circular motions for 30-60 seconds. Pay extra attention to oily areas like the T-zone.

4

Rinse Thoroughly

Rinse completely with lukewarm water, ensuring no residue remains. Pat dry with a clean towel—don't rub!

06

Frequently asked questions

FAQ

Use with caution. This cleanser contains 0.5% Salicylic Acid. While topical salicylic acid at concentrations under 2% in rinse-off products is generally considered safe by the American College of Obstetricians and Gynecologists (ACOG), it's always best to consult your healthcare provider before use during pregnancy or breastfeeding. Since it's a rinse-off product with short skin contact time, absorption is minimal.

No, this cleanser is NOT safe for fungal acne. It contains multiple fatty acids including Stearic Acid, Myristic Acid, Palmitic Acid, Lauric Acid, Oleic Acid, and Arachidic Acid. These fatty acids can feed Malassezia yeast and potentially worsen fungal acne. If you have fungal acne, consider alternatives like Paula's Choice CLEAR Cleanser or Vanicream Gentle Facial Cleanser.

Yes, but with care. Since this cleanser contains 0.5% Salicylic Acid (BHA), be cautious about layering too many exfoliating actives. Using it with additional BHA products may cause over-exfoliation. It's generally safe to use with retinol and Vitamin C (apply these after cleansing). If using AHAs, consider alternating days or using this cleanser in the AM and AHA treatments in the PM. Always listen to your skin and reduce frequency if irritation occurs.

This cleanser is best suited for oily, combination, and acne-prone skin types. It's specifically formulated to control excess sebum, unclog pores, and prevent breakouts while the Centella complex soothes inflammation. It can also work for sensitive skin (hypoallergenic, dermatologist-tested), but those with very dry skin may find it slightly drying and should follow with a hydrating routine.

Most users notice cleaner-feeling skin immediately after first use. Visible improvements in acne and skin texture typically begin around weeks 2-4 with consistent use. Significant clearing and prevention of new breakouts is usually achieved by weeks 6-8. Some users may experience initial purging in the first 1-2 weeks as pores clear out—this is normal and temporary.

Use this as your water-based cleanser (Step 2) in a double-cleanse routine after an oil cleanser, or as your only cleanser if not wearing makeup/sunscreen. Follow with toner, serum, moisturizer, and sunscreen (AM). It can be used both morning and evening. The cleanser is meant to be rinsed off, so apply to damp skin, massage for 30-60 seconds, then rinse thoroughly.

No, this cleanser is non-comedogenic with a rating of 1/5 (very low). It's dermatologist-tested and specifically designed NOT to clog pores. In fact, the Salicylic Acid actively works to unclog pores by dissolving the bonds between dead skin cells. The formula is also oil-free and silicone-free, further reducing any risk of pore congestion.

The product has a 12-month Period After Opening (PAO). Once opened, use within 12 months for optimal efficacy and safety. The 150ml tube typically lasts 2-4 months with twice-daily use, as a little product goes a long way. Store in a cool, dry place away from direct sunlight and keep the cap tightly closed to maintain freshness.

— Skincarisma verdict
4.5 / 5 ★★★★★

Verdict: The COSRX AC Collection Calming Foam Cleanser is an excellent daily cleanser for those battling oily, acne-prone skin. The combination of proven Salicylic Acid with the soothing CentellAC-RX Complex delivers effective acne treatment without the harsh, stripping sensation of typical acne cleansers. While not suitable for fungal acne sufferers and containing natural fragrance that may bother some users, it offers outstanding value, gentle-yet-effective cleansing, and visible results within weeks. A worthy upgrade from the original COSRX Salicylic Acid Cleanser and a solid K-beauty staple for clearer skin.

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.

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.
