In our quest to eradicate zits we’ve tried our fair share of pimple-busting products—with mixed results. This radical serum may very well be The One. The doctor-developed formula penetrates the skin, going straight to the source to eliminate trapped bacteria, dirt, and oil to restore damaged skin. It gets the job done quickly and gently, without irritating or over-drying your skin. The patent-pending YS3 Complex delivers blemish-banishing ingredients, like tea tree oil and salicylic acid, beneath the skin’s surface. Willow bark extract reduces inflammation and redness. Bonus: The serum also tackles surface scars and hyperpigmentation.
This product is amazing! I use it as a spot treatment, during my monthly break outs and I notice a difference within 24 hours. This serum is light and not oily on the skin.5
This sample lasted me so long because it worked so well that I babied the little guy to the last drop, then cut it open to use the last little bit! I just came back to buy the full size because I have some stubborn blemishes that need this right now!5
Does truly help get rid of blemishes. I put it on at night and when I wake up the blemishes have reduced greatly. Will definitely be buying more of this!!5
This is the first skincare product I've used that clears up my breakouts without drying out my skin or irritating. I also saw results after the first use. I highly suggest for spot treatment or for overall preventative use every day. Definitely purchasing a full size bottle!5
This product worked wonders! Was very pleased. When first received did not know what to expect but was for sure great!5
Everyone's skin reacts differently to every product...mine, for one, hardly ever clears blemishes with something I bought at ulta or the drug store. THIS IS MY FAVORITE SAMPLE. This stuff is amazing. I definitely say the price is worth it for the full size. It doesn't get used everyday, so you can easily make it last.5
I never had acne in my life until about 8 months ago, after switching my birth control. I also have very dry skin and most spot treatments that I have tried were not effective enough at clearing my hormonal acne to be worth the drying side effects. This stuff is amazing. I've been using it for about a month now and my skin is almost completely cleared up. I just have a few slight red spots left from some serious cystic pimples, but they are becoming less noticeable daily. This is the only spot treatment I have tried that not only works, but actually leaves my face feeling just as moisturized as it was before applying it. It didn't work instantaneously, but a month in I am definitely seeing the results I want.5
I have chronic, very red and inflamed acne all along my jawline. After a particularly bad breakout, I went back to my Birchbox stash and found this serum. I've used it at night the last two nights, completely covering my jawline, and the redness has decreased dramatically, the bumps are half the size, and none of the bumps are painful any longer. I have dealt with bad breakouts for so long that I am hoping this may be the perfect treatment!5
I loved this serum and am going to buy the full size. It was the best combination of mighty power without causing any tenderness, redness, or dryness to breakouts - tough enough for spot treatment, but also gentle enough as an all-over serum. Dark spots and acne scars were also minimized after consistent use over about a week+. Great product.5
This product is seriously amazing. I have never had a blemish treatment that gave results overnight and this did!! Put it on when you are feeling a blemish coming on, and it will be cleared up before you know it.5
