Folic Acid
Folic Acid, also known as Vitamin B9, is a water-soluble vitamin crucial for DNA synthesis, cell division, and tissue growth. While primarily associated with prenatal health and supplementation, Folic Acid has emerging applications in topical skincare due to its role in supporting cellular regeneration, epidermal repair, and hydration.
In skincare formulations, Folic Acid helps stimulate the turnover of keratinocytes in the basal layer of the epidermis, promoting faster renewal of the skin surface. It may also improve the skin’s natural barrier function and support collagen maintenance. Often used alongside other B-complex vitamins like Niacinamide (B3) and Panthenol (B5), it helps address skin fatigue, dryness, and sensitivity, making it a valuable ingredient in barrier-repair products and revitalising treatments.
Benefits for Skin
- Supports epidermal regeneration and healthy cell turnover, promoting fresher-looking skin.
- Improves moisture retention by enhancing the skin barrier and hydration pathways.
- May contribute to improved elasticity and dermal support when combined with collagen-supporting actives.
- Helps reduce visible signs of skin fatigue and dullness caused by environmental stress.
- Often used in post-treatment products to accelerate recovery and repair.
- Suitable for sensitive, dry, and mature skin types looking for hydration and repair benefits.
