    Good up to a point ...
    January 1, 2019
    This would be a good starting point for those who haven't used any type of BHA before as it is quite a low concentration. Very easy to apply at night before bed. Not at all irritating and I do notice the reduction of those annoying little bumps the next day.

    love it!
    February 25, 2020
    I have oily combo acne prone skin, and the first time I tried this cream I felt quite uncertain about whether it was suitable for me or not. the cream is quite thick and usually thick creams tend to clog my pores and cause breakout, but I luckily didn’t experience any of that with this cream! I’ve used up a whole tube now and I but another one! I can definetely see an improvement on my skin after using the cream regurlarly on a daily basis. I use it mainly as a night cream, but also used it sometimes as a day cream since it was really cold this winter. The cream is really moisturizing, nourishing and gentle on the skin! good for any skintype I feel. After using this cream, my skin looks and feels much smoother and a lot of my acne bumps have settled down. This tube of cream lasts for quite a while! since a little goes a long way! highly recommend!

    Clearer Skin
    November 24, 2018
    After a week of use my face appears to be more clear and smooth. My marks from pimples has gradually faded, it may take more time but I see the difference. I use this on top of rosehip oil every night.

    Bye bye dull skin
    July 10, 2020
    This overnight mask could really drive away the dull skin that I had. Next day when I woke up, my face looked hydrated. I had little small bumps under my skin, so I decided to try this product.
    Small bumps are gradually disappearing.
    I am using this product two times a week.

    Perfect for spot treatment
    June 25, 2020
    I used the previous version, Cosrx BHA Blackhead power cream, only for spot treatment with pimples and the odd stubborn blackhead. This feels like the same cream, it speeds up the process of my pimples a lot and protects from bacteria, just out a little blob on the spot and it either opens or goes away.
    I can’t use this on all my face because I am extremely sensitive
  • Liyah Hamilton
    love this
    June 24, 2020
    my skin cleared up after a week of using this. it has a nice texture and is not too tacky in the skin

    must have combi oily acne skin
    June 15, 2020
    I use the mask at night a couple of times a week. It is quite dense, absorbs well, slides when applied, you can adjust the number of applications, if you overdo it by applying to the neck area, it sticks there, but I agree, because the result is amazing!
    Acids in it cleanse and narrow pores, open them and prevent the formation of clogged pores and rashes.
    The composition also includes tea tree oil, which works great for me as an anti-inflammatory and antibacterial agent.
    Some also have a primary rash of bha addiction. I didn't know about it at all, I never had it. But the more we discuss this mask in a group, the more I learn the details.
    If you are saved by products with bha, pha, dairy, tea tree oil and panthenol, then this is the remedy for you!
    Panthenol soothes the skin after acids and helps it to recover. Niacinamide, pha and milk help fight pigmentation. Niacinamide itself also improves microcirculation, rids the skin of age-related pigmentation and helps it take on a younger solid color.
    And the highlight of this mask is the base of the whole composition, it is an extract of everyone's favorite soothing and relieving redness, preventing inflammation of the Asian centella.

    I have used this for almost a month now and I can really tell the difference it has made on my skin. The texture is amazing!

    Love it!
    May 18, 2020
    As the title states it, I am loving it. It is a nice thicker consistency that doesn't feel sticky, like some of my night creams feel like. It has a nice cooling sensation and to be honest, has a light vapor rub scent to it that I absolutely love! The scent does desapade. I feel my face hydrated and not drying.

    ABSOLUTELY LOVE THIS STUFF!! is great for my skin even though it’s sensitive, leaves my face feeling baby smooth.

    it doesnt have a strong scent and is very easy to use. it spreads out easily as it has a light consistency. rather than the bha i think its more moisturizing. i find it more moisturizing than the rice mask which is also great. the tube design is very hygienic, somwthing that i love.
