I love this product - shockingly, it seems to help my cystic acne more than anything else. I do use the whole skin type 1 system, but I honestly think if you only can choose one product from the line, it should be this one. I have bought two full sized bottles over the past few years and it is worth the money.
I have had cystic acne for about 8 years, and had “dry” (combination) skin, that flaked, peeled, and somehow still got cysts all over it anyway. But this product keeps my skin from flaking and drying out and somehow makes my cysts smaller and less angry so quickly. And while my skin isn’t intensely oily, it does help my skin feel more balanced.
I do want to say that I also take spironolactone, which also helps me a lot, but without this serum my skin will still get new cysts. So this is 2000% my holy grail product. I had no idea the importance of actually healing and repairing my skin until I tried it.
Your skin will thank you!
