Your skin barrier is the outermost defense layer that keeps moisture in and irritants out. When it functions well, skin looks hydrated and smooth. When compromised, you see dryness, sensitivity and accelerated aging. Several vitamins play direct roles in maintaining this barrier.
Retinyl acetate (the form in our formula at 630mcg) supports normal keratinocyte differentiation. In practical terms, it helps skin cells mature properly as they migrate to the surface, ensuring the barrier layer forms correctly.
Collagen provides structural support beneath the barrier. Research confirms that Vitamin C is a required cofactor for collagen synthesis. Without it, the foundation beneath your barrier weakens.
Vitamin D receptors exist throughout the epidermis. At 10mcg (50% DV) in our formula, it supports the growth and differentiation of skin cells that form the barrier.
As a fat-soluble antioxidant, natural d-alpha tocopheryl acetate integrates directly into cell membranes. This is where it does its most important work — protecting the lipid bilayers that hold the barrier together from oxidative damage.
Topical products address the barrier from the outside. Oral supplements like Gelagen support it from within by ensuring the raw materials for barrier construction are available systemically. Both approaches complement each other.
