Vitamin A is one of the most well-researched nutrients for skin health. In our formula, it appears as retinyl acetate at 630mcg (70% Daily Value). Here is what that means for your skin and why dosing context matters.
Vitamin A influences how keratinocytes differentiate as they move from the basal layer to the skin surface. Proper differentiation produces a smoother, more even skin texture and a stronger barrier layer.
Retinoids help regulate sebaceous gland activity. This is why Vitamin A derivatives (retinol, tretinoin) are cornerstone ingredients in both prescription and over-the-counter skincare.
The upper tolerable intake for Vitamin A is 3000mcg RAE per day for adults. Our formula provides 630mcg — well within safe limits. However, pregnant women should be especially cautious: excessive Vitamin A intake during pregnancy is associated with birth defects. Always consult your physician.
Topical retinoids work directly on skin cells at the application site. Oral Vitamin A supports skin health systemically, ensuring cells throughout the body have access to this essential nutrient. Gelagen provides the oral component. Your skincare routine provides the topical one.
