Review: I bought this honestly kind of thinking that it was probably a fake product, since I had never seen any skincare with more than 2% salicylic acid, and it just sat on my shelf for a couple years until very recently, when my skin was the worst it has been in several years and I had several deep cystic pimples literally all over my face. I was desperate and had tried all of my other serums and treatments to no avail, and I decided to give this one a shot since I hadn’t ever really tested it and, again, I was desperate. Well, almost 2 weeks later and my skin is more or less totally clear again and the hyperpigmentation from the pimples are also fading very nicely! And I’ve experienced no dryness, redness or irritation. I just put a squirt of it into my palm and mix that with my moisturizer and put them on together each night and it does the trick. So, I give this product 5 stars, because it works so much better than I could have ever hoped and it’s very affordable, even now with inflation prices! Buy this if your skin is sensitive but you need serious acne fighting ingredients. This product seems to do it all, at least for me :)
Review: 治り方バグ！高校生ニキビが治らなくて困ってたけど毛穴のポツポツ？みたいなのが原因でニキビ繰り返してる人とかにはすごいくらい効きます！自分は3日でざらつき減ったのがわかりました笑後保湿はかなり必須でクリームで蓋をしても翌朝少し突っ張ります連続しようは3日までですね。ニキビの薬使っても治らないって人は毛穴詰まりがあってそもそも薬が浸透しないってことが多いと思うのでその原因である詰まりをこれで解消すればすごいくらい肌綺麗になってニキビも治ります！自分は脂性肌でざらつきがあったので乾燥肌の人にはお勧めしません！脂性肌で毛穴詰まりの人特化という感じですね

## Questions & Answers

**Q: Why does it have Cocamidopropyl Dimethylamine?**
A: Cocamidopropyl Dimethylamine and Salicylic Acid are sold together as Curcylic 40 by cosmetic ingredient suppliers. It helps make the salicylic acid water soluble and more sense since usually SA is lipid soluble only.

**Q: Has anyone found that this serum reduces an oily face?**
A: I did not find that it helped to reduce sebum production. My sebum production remained the same when wearing the serum, which I only put on at night. If you wear it during the day, you'll need to make sure that you put sunscreen over it. Alternately, you can wear it with a mattifying moisturizer.

**Q: Can this be used on my scalp under my hair?**
A: Well guess your scalp is under your hair  but dear this is a face serum. Try ACV once a week mixed with same amt of water as a rinse. Use tree tea shampoo also if you have oily scalp issues. The ACV will also clean any product build up and makes your hair soft. Good luck. BTW, I returned this product as it was too drying for my skin.

**Q: What is the pH level?**
A: Ph level is between 3.3 ~ 3.7.

After trying everything and going backwards and forwards to the Drs about my acne, it's lovely to FINALLY find something that works! I use this morning and night, after washing my face with Cetaphil Oily Skin Cleanser and then waiting 30ish mins and applying Cetaphil Moisturising Cream - this combo has worked wonders and my skin is looking so much healthier! Can't recommend enough!
