Rated 5 out of 5 by High Inflation! Love this product, have been using it for years! Just came on to reorder it and the cost has gone up $12 since the last time I ordered it...why? May 21, 2015
Rated 5 out of 5 by Amazing product but too expensive I agree with all comments. The product is amazing but the price went up tooooo much. I've been using this for years but will probably start to shop around and see what's out there. December 15, 2014
Rated 5 out of 5 by Leaving water on my face when I use this product, I feel as if I save water on my face. Calming fragrance and light texture makes me feel relaxed. I recommended this product to my mother and she loves it too. October 21, 2014
Rated 5 out of 5 by Excellent Product but too pricey now! I have used this moisturizer for YEARS and it is the best that I have ever used. Unfortunately, the price just went up to $47. Last time I bought it, I paid about $36 or $38 (reasonable price) Now, I am going to have to shop around ....Too bad the price went up. I think this will be the last time I buy this product.

Rated 3 out of 5 by Shiny-shine I got it as a sample with purchase. I'm not going to get a full size. I have sensitive skin and this product irritated my skin. Besides it made my skin glow so much that it looked like oily shine. The fragrance is like men's perfume, which is not bad at all. September 19, 2014
Rated 4 out of 5 by Great product, just not worth it anymore. Like all the other reviewers mentioned, this is a great product for all skin types even the sensitive ones. The main reason I used aquasource is because it has the same result and of similar quality than other brands that has more expensive moisturizers. With the price increase (it used to be $36 and with 20% off promo from time to time it was $28.8!!!) I don't have any reason to stay with Biotherm. I don't know what Biotherm is thinking really...

Rated 4 out of 5 by love this moisturizer,but.. i've been using this product for many years. The price can be changed, I understand that, but I think this amount of increase is a little too much. I purchased this at $39 in this July, but now it is $47. Aquasource moisturizer for dry skin is also $47, but Aquasource skinperfection which came out to the market like an year and a half ago is still $41. I'm just hesitating to click order.
