I’ve been using this product for 2 years. I love using it and recommend it to all my friends and family. It truly helps visually improve fine lines and wrinkles on your face.

This serum has a positive impact on my 70 year old skin, making it more radiant and supple. I use it only at night, under my Blur Therapy Anti Aging Night cream. I am loving the compliments I get!

Absolutely love how my skin feels, it’s totally magic in a bottle.

I'm a fan of Biotherm, but they have to change this eye dropper bottle business! I'm losing way too much product!!! I know that I'm not the only one complaining too! I've been faithful for years Biotherm...your turn. Other than that, fantastic serum!

I have been using the Skin Best line for many years, and believed that I could never find a serum that I preferred to that one - but the Blue Therapy serum is wonderful, and I do prefer it to Skin Best. My only complaint is the delivery system - a regular pump would have been fine. I dislike the eyedropper - it's awkward to use, and I tend to lose product along the sides of the bottle when I'm replacing it (at this price, every drop is precious). Otherwise, 5 stars all the way!
