Review (5/5): Works as the other 50+ raters have stated...
I have adult onset acne. I have had it for over a decade. Nothing would cure it. Benzyl peroxide makes me break out worse and rash up. >2% salicylic acid spot treatment products help, but nothing really evened everything out and made the acne start to go away. I wouldn't say this is a miracle, but it certainly is the only thing that I have found in the past 10 years that works (and yes I have seen 3 dermatologists for this issue with no permanent resolution).
The Routine:
I apply this glycolic product 1x at night and a light face moisturizer 1x in the morning (plus an eye cream when I remember). I started seeing immediate results within less than 2 weeks. I also, after reading so many scarey reviews about negative product interactions, am happy to report that I had NO additional breakouts with the product and only light tingling for the first few minutes of application. I would compare this tingling to the feeling you get just after applying a witch hazel cotton pad (for those with pain concerns regarding the 'tingle' reported by others).
Regarding Results 2 Weeks In:
For those of us that have had long term acne and know how good we look in summertime (due to the sun hiding your acne spots) this is how I feel now, two weeks later, when I see myself in the mirror. I don't know how well it will treat these recesses (old acne scars) I have in my cheek area, but the red splotches are gone and skin tone has evened substantially.
I also should be honest and say that the use of a glycolic product was recommended to me from my identical twin sister (yay for matching DNA and two people trying to solve the same problem at once). Anyways, she used a similar AHA product for a year (not this one exactly). However, her acne, red splotches, break outs, and scars are completely gone after 1 year of use of an AHA glycolic product. After seeing her results I thought I would find a similar product to try. (keeping fingers crossed over this year!)
Opinion Section:
I saw a number of negative reviews. In reflection, I would suspect that sensitive youth skin may not benefit as much from this product as adult skin. I noticed that the product is far less drying on my face than advertised by others. Heck, I don't even bother to moisturize at night and have no ill over-drying effects. However, I worry that if you are purchasing the product for 'oil control' or have much oil production on your face this may aggravate your acne situation. I only comment this because when I get up in the morning I can still feel this product on my face - it's not greasy or oily, I just feel a sheen. This could explain some of the negative posters comments. In my experience, I think youth acne needs drying more than adult acne, which needs exfoliation. If you are in your mid 20s and up (and DO NOT have sensitive, oil - prone, raging hormone youth skin), then this product is relatively inexpensive and delivers!
PS: If there is a youth out there that has the opposite of this experience, please flag this (if this review section will allow it) to remove this last paragraph for accuracy as i do not want my speculation to mislead people on a product that is in my opinion, from first hand experience, absolutely wonderful.
