Cellular changes will vary from skin concern to skin concern. For example, skin cell turnover, or the ‘sloughing off’ of the top layer of the skin, leads to more radiance and smoother texture. Adding moisture to the outer layer of the skin can have a plumping effect on skin cells, which will help minimize the appearance of fine lines. Permanent improvement in fine lines and wrinkles is slightly more complicated since it relies on new collagen production, which occurs in a deeper layer of the skin. Our skin’s collagen production naturally decreases as we get older.
