The full review.
A cleanser promising centella-powered gentleness while using a true soap formulation with a pH near 9 is a contradiction. The COSRX Pure Fit Cica Creamy Foam Cleanser works in two directions; which side wins depends on your cleansing priorities.
The foam is excellent. Squeeze a small amount onto damp hands, add water, and the saponified fatty acid base produces a dense, pillowy, whipped-cream-like lather. This is not the thin, bubbly foam of a sulfate-based cleanser or the light lather of a gentle gel. It is a thick, satisfying foam. For anyone who associates a rich lather with a thorough cleanse, this product delivers.
The chemistry behind the foam is complicated. Myristic acid, palmitic acid, stearic acid, and lauric acid are saponified with potassium hydroxide to create the cleansing base. This is true soap—the same chemistry used since ancient Babylon. True soap produces exceptional foam, but it also produces a pH of approximately 9, which independent testing confirmed for this product. Skin’s natural pH sits between 4.5 and 5.5. A cleanser at pH 9 temporarily disrupts the acid mantle. Decades of dermatological research show that chronic exposure to high-pH cleansers can compromise barrier function, increase TEWL, and cause irritation and sensitivity.
This is the central issue. COSRX formulated this product with their proprietary CICA-7 Complex—seven distinct centella asiatica derivatives, including three whole-plant extracts and four isolated triterpenoids—and placed it in their sensitive skin recovery line. Centella asiatica has clinical evidence for soothing inflammation and supporting barrier repair. But in a wash-off product with 30 to 60 seconds of skin contact, at a pH that undermines the barrier the centella tries to protect, the soothing claim is inconsistent. It is like running a hot bath and adding ice cubes.
Essential oils add more contradiction. Eucalyptus, lavender, mandarin, and pine oils provide a fresh, herbaceous scent that works if you like a woodland profile. However, these are documented contact sensitizers. Including them in a product for sensitive skin repair is a questionable decision. Descriptions of the scent range from refreshing greenery to stale dustiness.
For oily and combination skin, this may matter less. Oily skin often wants a thorough cleanse that strips excess sebum, and a subsequent toner in a routine can quickly correct the temporary pH disruption. The dense foam feels more effective than some gel and cream cleansers. For users whose skin produces enough oil to buffer the high pH, post-cleanse tightness may be minimal. The sulfate-free claim is accurate, even if the formula’s gentleness does not match the label’s implication.
The 150ml tube at approximately 4 offers good volume, lasting two to three months with twice-daily use. The packaging is functional and travel-friendly. Glycerin is listed second after water, providing meaningful humectant support during cleansing to defend against the stripping potential of the soap base.
The COSRX Pure Fit Cica Creamy Foam Cleanser reveals a tension in the Pure Fit Cica line. The original low-pH gel-type Cica Cleanser focused on sensitivity. The Creamy Foam Cleanser targets users wanting a satisfying foam experience, but using true soap chemistry contradicts the line’s gentle identity. COSRX could have used amino acid-based surfactants at a lower pH to get a rich foam. Choosing saponified fatty acids shows they prioritized foam quality over pH optimization.
For oily skin users who enjoy a rich lather, use a hydrating toner, and tolerate essential oils, this is a serviceable daily cleanser at a fair price. If you chose this product because “cica” promised gentleness for sensitive, reactive, or barrier-compromised skin, the formulation does not deliver. The centella is a passenger, not the driver.

The science.
The Science
This cleanser uses fatty acid saponification with potassium hydroxide. This chemistry produces potassium salts of fatty acids (true soap) with an alkaline pH. Korting et al. published research in Dermatology (1997) showing that repeated use of alkaline cleansers (pH 8-10) increases transepidermal water loss and changes skin surface lipid composition compared to acidic or neutral cleansers. The study shows even brief daily exposure to high-pH cleansing disrupts the acid mantle's recovery, with cumulative effects over weeks.
The centella asiatica compounds in this formula — specifically asiaticoside and madecassoside — have documented anti-inflammatory and barrier-supportive properties in leave-on applications. However, the pharmacokinetics of these compounds in a wash-off context are unfavorable. A 2011 study in the Journal of Pharmaceutical Sciences examining topical delivery of asiaticoside found that meaningful epidermal accumulation requires sustained contact times of 30 minutes or longer at optimal pH. The 30-60 seconds of contact time in a cleansing step, plus an alkaline pH that may alter the ionization state of these triterpenoids, results in minimal active delivery.
Lauric acid, one of the four fatty acids in the soap base, has documented antimicrobial activity against Cutibacterium acnes (formerly Propionibacterium acnes). Nakatsuji et al. found in a 2009 Journal of Investigative Dermatology study that lauric acid has stronger bactericidal activity against C. acnes than benzoyl peroxide in vitro. However, at pH 9, the saponified lauric acid exists as potassium laurate rather than free lauric acid, which may reduce its direct antimicrobial efficacy.

Dermatologist Perspective
Board-certified dermatologists recommend cleansers with a pH between 4.5 and 6.5 to maintain the skin's acid mantle. Most dermatologists would flag a cleanser at pH 9 as barrier-disruptive, especially for patients with rosacea, eczema, or compromised skin barrier. Dermatologists specializing in sensitive skin would note the gap between the centella branding and the formulation — centella asiatica is a respected soothing ingredient in leave-on products, but its inclusion in a high-pH wash-off product does not offset the alkaline disruption. The essential oils present also disqualify this cleanser from dermatological recommendations for sensitive or reactive skin.
Where it fits in your routine.
Wet your face and hands with lukewarm water. Squeeze about a centimeter onto your palms and lather with water. Massage the foam over your face in gentle circles for 30-60 seconds, targeting the T-zone and oily areas. Rinse well with lukewarm water; the dense foam needs more rinsing than thinner cleansers. Apply a low-pH hydrating toner immediately to rebalance the skin's acid mantle. Use this as a second cleanser in a double-cleansing routine after an oil-based first cleanser.
At about 4 for 150ml (with -12 discounts common on K-beauty retailers), the Creamy Foam Cleanser offers good volume for the price. The cost per use is low — roughly 15-20 cents for twice-daily use over 2-3 months. For oily skin types who like the thick foam and do not care about pH optimization, the value is reasonable. However, the gap between the premium cica branding and the basic soap chemistry means you do not pay for a sophisticated formulation — you pay for a well-packaged soap with centella ingredients that have limited practical benefit in this format.
Oily and combination skin types that want a thick foam and can tolerate essential oils will enjoy this cleanser most. It works as a second-step cleanser in a double-cleansing routine to remove oil and impurities.
Avoid this cleanser if you have dry, sensitive, or barrier-compromised skin. The pH of approximately 9 and essential oils contradict the gentle soothing the cica branding implies. People with rosacea, eczema, or fragrance sensitivity should use a low-pH, fragrance-free cleanser instead.

The backstory.
COSRX expanded its Pure Fit Cica cleansing line in June 2021, adding the Creamy Foam Cleanser alongside a cleansing balm and cleansing oil. The foam cleanser was designed for users who preferred a more traditional, foam-rich cleansing experience compared to the original low-pH gel-type Cica Cleanser. The true soap formulation was a deliberate choice for the dense lather it produces, though it came at the cost of a higher pH than skin science generally recommends.

Common myths.
The centella complex in this cleanser soothes the skin.
With 30-60 seconds of skin contact, a wash-off product gives centella compounds little time to penetrate and deliver anti-inflammatory benefits. The high pH (~9) also reduces the efficacy of these actives. Leave-on products in the routine do the real soothing work.
Sulfate-free means this cleanser is gentle on the skin.
This cleanser is technically sulfate-free, but its saponified fatty acid base has a pH of approximately 9. This is well above the skin's natural pH of 4.5-5.5. High-pH cleansers disrupt the acid mantle and compromise barrier function, even without sulfates.
FAQ.
What is the pH of the COSRX Pure Fit Cica Creamy Foam Cleanser?
Independent testing shows the pH is approximately 9.0, well above the skin-friendly 4.5-5.5 range. This high pH comes from the true soap formulation (saponified fatty acids). Use a low-pH hydrating toner after use to rebalance the skin's acid mantle.
Is the COSRX Cica Foam Cleanser good for sensitive skin?
This cleanser is not ideal for sensitive skin, despite the "cica" branding. A pH of approximately 9 disrupts the skin barrier. The formula also contains multiple essential oils (eucalyptus, lavender, mandarin, pine) that are known potential irritants. Sensitive skin types should use a low-pH, fragrance-free gel cleanser instead.
Does the centella in the COSRX Cica Foam Cleanser actually work?
The CICA-7 Complex has seven centella-derived ingredients. Because this wash-off product only touches skin for 30-60 seconds, these actives have little time to penetrate or work. Leave-on products like the COSRX Pure Fit Cica Cream or Serum provide better centella soothing benefits.
Why does the COSRX Cica Foam Cleanser feel tight after use?
The tightness comes from the saponified fatty acid base's high pH (~9). True soap formulations strip natural skin oils more aggressively than synthetic surfactants and temporarily disrupt the acid mantle. Using a hydrating, low-pH toner immediately after helps mitigate this effect.
Is the COSRX Cica Foam Cleanser sulfate-free?
Yes — this cleanser uses saponified fatty acids (myristic, palmitic, stearic, and lauric acid with potassium hydroxide) instead of sulfate-based surfactants like SLS or SLES. But sulfate-free isn't always gentle. The saponification process creates a high-pH formula that can strip skin more than some sulfate-based cleansers.
