Synopsis
Source of validity: Scientific
Rating (out of 5): 4
Vitamin C is a well-established ingredient in skin care, supported by substantial scientific evidence. Ascorbic acid (vitamin C) acts as a potent antioxidant, helping to neutralize free radicals generated by UV exposure and environmental pollutants, both of which contribute to skin aging and damage. Numerous in vitro and in vivo studies demonstrate that topical vitamin C can stimulate collagen synthesis, which is essential for maintaining skin elasticity and reducing the appearance of fine lines and wrinkles. Clinical trials have shown that vitamin C can help brighten skin tone, diminish hyperpigmentation (such as dark spots), and improve overall skin texture. Its role in inhibiting melanin production makes it effective for treating melasma and other forms of hyperpigmentation.
Vitamin C is also known to aid in wound healing by supporting dermal fibroblast function and facilitating the formation of the skin barrier. Topical formulations are often preferred in dermatology, as oral supplementation has limited direct impact on skin due to tightly regulated blood levels of vitamin C. However, formulation stability is a concern, as vitamin C degrades with exposure to light and air.
Overall, the scientific literature supports the use of vitamin C in skin care for its antioxidant, anti-aging, and skin-brightening properties, making it a mainstay ingredient in many dermatological and cosmetic products.
