The Mermaid Collagen Serum is for sure one of the products we are most proud of. The chemist we developed this with is incredible and we went back and forth with him for countless rounds of sampling to get this serum just right. We packed it full of incredible ingredients. The formula is 47% Marine Collagen, which is the only form of collagen that can effectively penetrate the skin. It also has a lot of soothing and hydrating ingredients to help that not only help diminish the appearance of fine lines and wrinkles, but it helps with pore size and leaves skin with a really beautiful, healthy glow. It took us a couple of years to get this product just right, and we are so proud of how it turned out. It’s probably the product that people ask me about most frequently, and then that they later follow up with how much they now can’t live without it.
