Works well
I have large pores and at my last facial I was told I should find a lactic acid serum and charcoal mask. I’ve used it once a week for three weeks. I haven’t noticed my pores getting smaller, but My skin feels cleaner and clearer after using.

Must buy!
I’ve been using this stuff for over a year and I’m obsessed with it! I use about 4 drops for my face and neck so the product does go a long way. It’s great at exfoliating and keeps my skin super soft!

Shocked!
I read an article that recommended trying lactic acid because Lactic acid brightens dullness, smooths, and evens skin, while also making it look firmer. It helps reduce the appearance of fine lines, wrinkles, and dark spots. So I thought why not try it. I am a 54 year old very fair skinned woman who has very sensitive skin. Especially on my face. When I write that this product is fantastic I am not overreacting. It has made my skin look so even, brighter and has made my red cheeks almost disappear. Just after several days!!! I HIGHLY recommend this product. It really works!!!!

Effective and fast exfoliation without discomfort-May be drying
I have used a variety of exfoliating serums. This Lactic Acid 12.5 serum is fast and effective. I have found that it is very important to moisturize heavily after use. I have noticed that my skin has looked drier in areas compared to other serums I have used for exfoliation. However, it is clearer and my skin is looking balanced and clear. This serum is comparable to several professional beauty care exfoliation products. Lactic acid is said to be milder than glycolic acid. However, this seems stronger than I expected as I am experiencing dryness. I am using the serum 2-3 times per week and following up with a moisturizer. The hyaluronic acid allows it to glide on my skin with ease. It stings slightly but nothing that is too uncomfortable. I like it so far and will update as needed with further time and use. Suggestions for improvement -larger supply/container -directions for after use (moisturize and when to put moisturizer on) some products say wait for five minutes after the product is applied.

Writing this as I purchase my 2nd bottle
For this price point, you cannot go wrong trying this. It's a water like fluid that glides on your skin and absorbs quickly. I use it maybe 3 times a week to brighten and exfoliate my skin and it works great. Since it is an acid, use it sparingly and only a few times a week. I'm so glad that I took a chance on this product!
