Feels good on skin - non-irritating [SEP] This BH DERMCENTER Retinol Serum is made in the USA. This serum is paraben free, vegan, non-GMO, and gluten free. A little of this serum goes along way. It can be used daily under your moisturizer. It contains retinal which is supposed to restore collagen to your skin, lighten dark spots, and hide fine wrinkles. Only time will tell if this serum lives up to its claims. However, I like the way it feels on my skin and it was non-irritating. Overall, I recommend this product.
