Feels like it's working
Feels like it's working. Only used for a little while but it feels as though it's actively trying to improve my skin when I put it on.

caused breakouts for me
I used only this product alongside a moisturizer I have been using for years and the morning after using this product, every time, i break out. I try to use it only every few days but to no avail. I then went on vacation and didn't use it at all, and my skin cleared up. would not recommend

I need a help. What serum should I use? I have combination skin with open pores on my cheeks and nose and chin area. I have bumpy skin on chin area. Also have clogged pores full with some sort of semi solid and oily thing on nose and chin. Skin looks dull. In summer I get too oily skin especially nose and chin but in winter I get a dry skin.

Amazing!
I had a breakout of adult acne due to stress. I should’ve read the ingredients list but I initially had a horrible reaction against the medication I was taking. After adjusting the dosage and checking how much my skin could tolerate, I’ve been using this at night on alternative nights alongside antibiotics tablets. Previously my skin was reacting terribly but for the last two months I have seen major improvement. The acne was so bad that wearing matte makeup made it look worse. Not I can wear matte make up and not feel horrible. I’m hoping to using sheer make up with blemish corrections soon.

Cleared my Skin up in 6 weeks
I suffer with hormonal, bacterial acne. In summer months it worsens, I was hunting for a routine to keep blemishes at bay. I have been using this for 6 weeks, morning and night with my cleanser. I can honestly say its changed my skin, I don’t have spots come as much, it’s made scars fade and skin overall looks brighter. It’s a must for me now!
* it did cause my skin to “purge” that lasted about a week.

Burnt my skin
My face was on fire for days after using this serum. Gave me a chemical burn! Feels too strong and I can't find any information on what is the concentration of acids in there.

Sensitive skin... Doesn’t work. If you have acne……
It didn't work for me. My skin is sensitive and I have mild acne, but this product helped increase my tolerance to acne and now I have two problems. I had no results in 4 weeks of application, as mentioned in the packaging that it would have worked. I stopped using it.

Hello, Is this ok for sensitive skin? also, can I use this 2-3 times a week when I do not use my retinol, as I use 0.1% retinol?

Is this suitable for Rosacea

Hiya, Can this be used with retinol?
It contains salicylic acid which is a BHA (chemical exfoliant) so not a good match with retinol due to risk of irritation
