Rated 5 out of 5 by Blue Therapy Serum I think it works very effectively for my skin. I receive compliments all the time on how few wrinkles I have for a 72 year old. I definitely recommend this product. I love it! April 12, 2015
Rated 5 out of 5 by perfect! I had really dry skin before use it.. After I used 2 times...get better! !!! March 12, 2015
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
Rated 5 out of 5 by The best! I've tried many products, just this one really works May 31, 2014
Rated 4 out of 5 by Easy to apply It feels good on my skin. I have dry skin and this product goes on smoothly and makes my skin feel velvety. It is a good anti-aging product. Using it in conjunction with a night cream seems to create softer skin. The product is great for firming the skin and lessoning wrinkles. The texture of the serum feels good going on May 9, 2014
Rated 5 out of 5 by Quality product with easy and clean application This is one of the best products I have used to improve my skin condition, and I can see the difference. April 2, 2014
