I got the Acne.org regimen and added this after playing around with the regimen for 3 months and thinking I needed something to deal with the ice pick texture and the post-acne pigmentation. Prior to this, I had never really had any other AHA so I didn't know what to expect. Even though I don't have sensitive skin, it definitely tingles, especially after I've already exfoliated (either with other chemical toners) or with dermaplaning, which doesn't mean that the product is bad necessarily, I recognize that I am exfoliating a lot more than perhaps recommended. Anyways, I don't use this all over, just as a spot treatment moisturizer...if that makes sense. I can't use the Acne.org moisturizer during the day because it pills up like crazy, even without any makeup. Instead I use this, but please not that it is not advised since it is a chemical exfoliate and makes you more sun-sensitive. To compensate for this, I reapply sunscreen every 3-4 hours and use a sun umbrella if I go outside even just for a few minutes.
Anyways, back to the product...it applies light yellow, like the Acne.org moisturizer but dries clear. It has a little bit of sheen but nothing that a dab of powder can't handle. I do like how it seems to dry out my whiteheads faster and encourages skin cell turnover. It is still a slow process, so I have seen just a bit of progress on the ice pick scars but I'm hopeful!
Keep at it and maybe don't use it exactly like I do, but it works.
