A few years ago I worked in a World Class Spa and this was the facial line the estheticians campaigned hard to get into the spa. Epicuren products are paraben-free, and the company is committed to formulating natural products that have visible results. I was able to not only use this product myself, but see the results on many spa customers. The Epicuren Colostrum Serum is expensive, but absolutely worth it, especially if you have skin that is prone to acne. You only need to use a pea-sized amount for your entire face. That seems unlikely, but it is true, because it glides and spreads easily. So an expensive bottle can go a very long way. The packaging is not the prettiest or most trendy, but the product itself is what's important. The smell is very mild and will not compete with anything else you are using. This is a great, sustainable company using only the purest of ingredients.
