Mackenzie Roach - 2021It actually works2019年6月10日I have terrible acne on my t-zone due to my combination like skin. Some days I am oily while others I am dry, but this serum did not only get rid of my acne, blemishes, redness, acne scars, and more. It also left my skin smoothe and refreshed. I noticed major improvements within the first two days.
RadaGreat serum!2019年6月7日I really enjoy using this serum. It works really well with my combination skin. My breakouts are less frequent, skin is less oily during the day and any active breakouts that I had when I started using it - disappeared.
It is not drying at all and feels calming.
Justin DunnSerum of prayers2019年6月1日helps everything look fresh and feel so good post application. great item to improve skin texture and overall appearance when that ghastly spot appears :-(
JLTested it out for a week and so2019年5月12日It has a nice, slightly medicated smell to it! It absorbs super quickly and is really runny on the skin. It really helps clear up redness and spots and no big acne spots have formed. I’ll provably get another one when I run out 👌👌👌 the grass bottle it comes in also keeps it kinda cool, so it’s refreshing to use after I wake up or after a day of going outside :)Just got it2019年4月30日Just got the product in the mail today and I’ll add on a review later to see how much it works! For now, the packaging is very sanitary and the bottle itself is frosted glass, and on the box it comes in it has instructions and ingredients in English on the side.
shiintoSO GOOD!2019年4月26日I love this serum so much! actually helped to calm down my red and angry pimples. smells great and soothed my skin a lot!! im glad costs came out with this new line! would definitely recommend the rx line!
JenefferAbsorbs in your skin quickly2019年4月11日Just using this for 2 weeks and it looks like it works wonders. One thing I noticed is it get easily absorbed. Not sticky. I will continue on using this
LuisaVery liquid serum2019年6月10日I was used to more sticky serum, but this one is very fluid one. It has a medical scent. I love the packaging, it’s essential and clean. About effectiveness, I didn’t see any great change, but maybe with patience...
AmberGood2019年6月4日It doesn't help much with my acne but it tones my skin a bit.
Amy BrownI like the smell2019年5月18日I have been using it for a week only so I have not seen any changes in my scars. I will have to use it more to see any result. I hope I will. i was using the all-in-one snail cream by mucin and it really helped me to faded some scars. now I am using this product with other new products.......not sure
SyakirSo-so2019年5月19日I've been using it for over a month and I have yet to see changes to my face. It irritates my skin and causes redness to it. We'll see in a few weeks time if it really is a good product for my skin.
AndreaNot effective!2019年5月26日I usually love COSRX products, but this product had no effect at all on my skin. I have found The Ordinary Niacinamide 10% + Zinc 1% serum to be much more effective and available at a much more reasonable price - both products contain Niacinamide which helps with acne scar clearing and skin tone refinement but The Ordinary serum was much more effective.
