My skin type is combo, dehydrated, and prone to hormonal breakouts.
This isn't something I would have actively sought out, as I'm in my early twenties and wrinkles aren't my main concern. But I received a generous sample of this serum as part of a gift with purchase earlier this year and fell in love with the way it made my skin look and feel. I don't have a lot of wrinkles, but I DO have issues with hyperpigmentation from breakouts. This, paired with my HG moisturizer (Alpha Hydrox 10% Enhanced Lotion) has given me the best looking skin I can ever remember seeing. When my sample ran out, I noticed a pretty big difference in my skin. Marks from pimples lingered far longer than they did when I was using the serum, and quite a bit of redness returned to my cheeks, nose, and chin. I repurchased, and have been using it again for about a month. My old marks are fading, and any new ones I get disappear within a week. The redness in my face has also calmed down a lot, and overall my skin tone is just far more even.
I apply it under my eyes as well (the only area I really have wrinkles), and although it helps to keep the area hydrated I haven't seen any real reduction in the fine lines there. I'll give it more time though, I know nothing is an overnight process.
I think if you're looking for serious help with wrinkles, this may not be the serum for you. I don't think it's heavy duty enough for more than fine lines. But if your issues are pigmentation related, I'd give this a try. It's done great things for me, and I'll continue to repurchase it.
