    What Users Say About COSRX

    From an analysis of user reviews, users consistently mention the following:

    What Users Love

    Many users evaluated Cosalx products as generally gentle and non-irritating overall. In particular, pad products are effective at removing impurities and dead skin cells, with many opinions that skin becomes smooth and hydrated after use. The 6 Peptide Skin Booster Serum, despite its lightweight formula, helps with hydration and skin texture improvement, and it is frequently mentioned that makeup applies well when used before makeup application. The cleansing water product is mildly acidic, gentle yet excellent in cleansing power, and reportedly removes makeup residue cleanly. Many users preferred fragrance-free or subtle scents, and satisfaction with the pump container and hygienic packaging was also high.

    Common Concerns

    For some functional products (whitening, wrinkle improvement), there were opinions that dramatic effects are difficult to feel immediately. Lightweight serums can be difficult to control the amount or take time to absorb, causing some users to feel stickiness, and some experienced dryness when used alone. Some users of pad products experienced skin irritation from friction or tightness in dry skin, and it was also mentioned that caution is needed during daytime care. The cleansing water has limitations in removing waterproof makeup, and it was advised to use a separate remover. Some improvements were suggested regarding the containers of certain products (pad container lid, toner amount control).

    Overall Summary

    According to reviews, Cosalx products provide satisfaction to many users with their gentle and low-irritant feel and excellent cleansing and exfoliating effects. Overall, the products are faithful to basic skincare and highly versatile, but there may be individual differences in the perception of some functional effects and usage experience.
