Good MoleculesMandelic Acid Serum

This stuff really works. I did some research and chose this over glycolic acid because this seemed better for sensitive skin. And it was! It actually removed dead skin, like actual dead skin came off. I know it was skin because it gradually became less and less. I also don't experience any burning or irritation with this product. It's great! I will keep using it. I love good molecules!

This is a must have in my very very simple skincare routine, good molecules never disappoints. i have extremely sensitive skin and I use tretinoin so I was hesitant to try a chemical exfoliating, but this was gentle enough not to bother my skin and I actually found it to be more effective than the tret. I use it with hyaluronic acid and squalene oil on top

This item has become a skin care staple for me. I use it twice a week after my evening shower.I have found this product is very effective and has helped clear my skin. It is a light weight formula and lightweight. It is slightly sticky but after I apply moisturizer, it's very comfortable.I'll continue to purchase this product.

Bought in lieu of Paulas choice pricier version. effective at improving texture and reducing dark areas. it is thicker and will pill slightly if apples in the AM so I stick with PM application before moisturizer

Good molecules is a such a great brand. I enjoy all of their products because they have made a real difference in my skin.

Great product!

I should start by saying I haven't been using this long enough to notice any significant changes. However I love this line so much and I haven't ran across a product from them that performs poorly yet. The texture is super thick and leaves a bit of stickyness but it eventually absorbs and your skin does have that primed look after. I hope this will be great as all the others.

This is easy to apply like a serum and a great price for what it is. Helps with redness tremendously and just making your skin look more healthy. Would highly recommended to add to your routine. I use it every night before moisturizer. Hydrating and great quality.
