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!

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 saw another review that said Blue Therapy worked well with Skin Vivo. I agree. The only thing I don't like is the medicine dropper delivery system. I'd prefer a pump like Source Therapy.

This product provides/promotes a beautiful & healthy look; it gives me a young glow, but I hate the dropper. I do not understand the purpose of the dropper; it is very user Unfriendly. I also assume that this dropper would be very diffiucult for an elderly to handle. I am a little younger then 60 years of age and have a hard time squeezing out the drops on to my face and fingers. I feel it should be packaged differently. Other then the bottle packaging, I love Blue Therapy Serum & would recommend it to my friends and family

I started using this product when I was no longer able to get Skin Vivo Serum. It's a wonderful product and goes on very easily. I am not a fan of the eye dropper. I do not think it works as well as it may have been intended to work. I would much prefer a pump.

I love the product, but like the tube on the sample better than the dropper style on the purchase product. I end up not using the dropper because the product is too thick for the dropper. I just place a small drop on my hand and use it. Using the dropper is clumsy and annoying. Also the sample lasts quite a long time due to the style of tube

Wonderful serum, smooth and easy to use. My only complaint is the bottle. It's impossible to see how much is left in it. So ordering new product gets tricky.

I've only been using this product as a sample but I love it. I've been using it around my eyes and I've noticed smoother and tighter skin already after only a few days. I'm not crazy about gels but this one is cooling and not sticky at all. I will be buying it for sure in the future.

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!

It works. My age spots are fading and my skin feels smoother.
