Rated 5 out of 5 by Love the way it feels on my skin I really like the way my skin feel when I use this product. The price is more than I can continue to pay unless there are deals offered. I have only been using this product for a while and can already tell a difference in my skin. I do love your products. December 13, 2014
Rated 3 out of 5 by Good product, bad design I had free samples of this serum, and I liked it a lot, so I've ordered the full size, and it's a total disaster - very inconvenient in use. I wish they had it in tubes, like their free samples, or a pump would be a good solution. Even a simple dropper would do, but not that kind of dropper they've got. Still a good serum :-) December 10, 2014
Rated 3 out of 5 by I just started using it 10 days ago. I don't see any results yet. Not enough moister for my face. But I love Biotherm so I will finish the product and then see the results. I have been using Biotherm since I was 20 years old and Now in my 50's I still love it. October 3, 2014

80% of the signs of aging can be visibly reduced.


Wrinkles appear smoother, contours feel tighter as though uplifted and dark spots appear reduced for a visible transformation. For all skin types.
