Which Vitamin Improves the Look of Your Skin?


Vitamin C, also known as ascorbic acid, is important for maintaining skin health and enhancing appearance. Its functions range from promoting collagen synthesis to providing antioxidant protection against environmental damage. Other elements, such as iron, also play a role in the appearance and health of the skin.


Collagen Synthesis and Skin Structure: Vitamin C stimulates collagen production, crucial for maintaining the skin’s structural integrity. Collagen is a protein that helps keep the skin firm and elastic, reducing the appearance of wrinkles and fine lines (Pullar et al., 2017).

Antioxidant Protection: Vitamin C is a powerful antioxidant that protects the skin from oxidative stress caused by UV radiation and pollution. This helps in preventing photodamage and reducing the risk of skin aging and hyperpigmentation (Wang et al., 2018).

Wound Healing and Anti-inflammatory Effects: Vitamin C enhances wound healing by promoting fibroblast proliferation and migration. It also has anti-inflammatory properties that can help manage conditions like atopic dermatitis and psoriasis (Duarte et al., 2009).

Skin Whitening and Brightening: As an effective depigmenting agent, vitamin C inhibits melanin synthesis, which helps in reducing dark spots and promoting a brighter, more even skin tone (Sugiura & Sugiura, 2018).

Topical vs. Dietary Vitamin C: Topical application and dietary vitamin C intake are beneficial. However, topical formulations are particularly effective in delivering high concentrations directly to the skin, enhancing its protective and reparative functions (Al-Niaimi & Chiang, 2017).

Photoprotection: Vitamin C provides photoprotection by reducing the formation of reactive oxygen species caused by UV exposure. This helps minimise sunburn and long-term UV damage (Darr et al., 1992).


Vitamin C plays a multifaceted role in skin health and appearance, from enhancing collagen synthesis and providing antioxidant protection to aiding in wound healing and skin brightening. Incorporating vitamin C into diet and skincare routines can significantly benefit overall skin health and aesthetics.
