I am 37 years old. I was intrigued to find this product since most salicylic acid serums contain only salicylic 2% and the expectation is that a high percentage won't really work better. I have found that to not be the case with this serum. While I was enjoying using the ordinary's 2% salicylic serum on my breakouts, this one works better and faster. The formulation is not drying and non irritating, so using this once a day on the areas with breakouts is completely fine. It is an excellent formulation and the included niacinamide which helps with balancing sebum production as well as brightening the skin is a bonus. A little goes a long way so do not apply to much of the product because you will have to keep rubbing it in for a while for complete absorption. I am a skincare junkie and highly recommend this for persons with acne.

I'm a regular user of Paula's Choice 2% BHA Liquid. I want to try a higher percentage of salicylic acid to combat the clogged pores and blackheads on my oily combo skin. I was initially wary that this high percentage might irritate my skin if i apply twice a day (like what i did with PC BHA). To my surprise, this formulation is very gentle on the skin. It does not dry up or irritate my skin. It even feels hydrating probably due to the high aloe vera content (first on the ingredient list). It is also accompanied by the powerful skin soothing duo of Artemisia and Green Tea. I appreciate the addition of brightening Niacinamide in the formulation as well. The texture is clear viscous liquid. The only downside, it creates white milky texture when you swirl this on the skin. But it will shortly get absorbed by the skin leaving no greasiness/tackiness. I apply twice a day, concentrating on my t-zone and large pores area.

Very effective salicylic acid. However, you need to use it very carefully! For those who are not very familiar with acids, I advise you to use it carefully - be sure to do a test. The acid concentration is quite high, so this product is not for sensitive skin. And it is imperative to use sunscreen, otherwise pigmentation is guaranteed to you. If my review helped you please mark thumb up, thanks 🙏❣️

I'm already in love with this brand so i've been waiting for these serums to be available since forever once i got notified that they're back i dropped that order right away hahaha still planning to get the peptide serum and centella serum. So it comes like it appears on photos sealed and well protected from the outside and inside, has the expiration date mentioned on the bottle which is a good thing in case you throw the packaging. Not opened nor tested yet cuz i'm already using the small niacinamide, vitamin c and retinol so i don't want to make it hard for my skin, but will be back with updates (LIKE FOR POINTS PLZ🙏🏻)

I highly recommend this product. You’ll see result instantly, however you see great results after about 3-4 weeks. I recommend doing a patch test first. I really hope everyone enjoys this product as much as I do! I’ve been dealing with hormonal acne because of some meds but this has saved my skin.

I love and swear by this brand! I needed a little extra boost to make a difference on my acne prone skin (pls remember to not use too many active ingredients on your acne, moisturizing and healing the skin barrier is key!!!!) and this did the trick! I use it one to two times a week depending on the state of my skin. Absorbs easily!

Oh WOW!!!!!! All the products I have been using in order to cler my skin for the past 6 months cannot compared to this one. I was overwhalmed with the effect it had on my forehead and nose. very light texture, absorbs quickly. Be extra gentle if your skin is not used to acids (mine does). I am going to order more products of this company - very impressed.

I am 34 with persistent blackheads around my nose and cheeks. I have used other chemical exfoliants in the past, and although they've helped, it was at the cost of some major stinging. The formulation from Cos de Baha lends a gentleness while still effectively removing blackheads. I use this along with a glycolic acid toner from The Ordinary twice to thrice a week, depending on my skin's needs. If you have sensitive skin, but need to get clearer skin, this may help without all the stinging.

Cos De BAHA offers a range of great quality serums at an affordable price and in a good packaging (glass instead of plastic). I bought both the S4 Salicylic Acid Serum and the Niacinamide 10 Serum which I use at night after cleansing my skin and before my night moisturiser. Both the Niacinamide and the Salicylic Acid are working in synergy helping me regulating the sebum production, reducing inflammation and making my pores look less visible: I have a mature, combination, very sensitive skin and both this products are really performing well so far. Both serums are transparent. The Salicylic Acid is easily absorbed and doesn't leave any residue on the skin. I am planning to buy again and again... Great brand worth a try! If my review helps, please kindly leave a thumbs up for me. Many many thanks!

It is also accompanied by the powerful skin soothing duo of Artemisia and Green Tea. I appreciate the addition of brightening Niacinamide in the formulation as well.

I apply twice a day, concentrating on my t-zone and large pores area.
