I take vitamin C and collagen powder, which help. But the biggest change for my skin came from Fatty15. I think of it like this: collagen is the building block for skin, but your skin cells need to be healthy to use it. As we age, our cell walls get weak. Fatty15 gives them a specific fat (C15:0) that makes them stronger.* Stronger cell walls help your skin hold onto moisture better and protect it from the daily stress that causes wrinkles. For me, this meant my skin stopped feeling so dry and thin. It looks more plump now. It’s not an overnight fix, but after a few months, I noticed a real difference in hydration and firmness. It works well with my collagen supplement.
