I found out about this gem of a company from a YouTube recommendation. The prices seemed very reasonable compared to the brand that I was using. I have dry and very sensitive skin. The sensitivity is what I have to be the most careful of. The review on YouTube said that the serums were ok for her sensitive skin and that, coupled with the pricing, was all that I needed to hear to take a chance. Shipping was prompt, something that one really hopes for when they are trying something new. I can say that I have experienced no sensitivity to any of the serums and I, in the short term that I have been using them, have noticed a softness, firmness and hydrated look for my face and neck. They were just what I was hoping for!
