Vitamin C has long been the go-to ingredient for brighter skin. Your daily serum or a refreshing citrus-packed smoothie, is often packed with vitamin C and is said to offer its glow-boosting, antioxidant powers. Many people swear by it to help fade dark spots, even out skin tone and protect against pollution damage. It’s that little daily ritual that feels like self-care in a bottle or glass, promising smoother, fresher-looking skin with every use.

Several people turn to Vitamin C because it makes their skin feel brighter, softer and healthier. It’s often seen as a skin shield, fighting dullness and boosting glow after sun exposure or stress. You apply it, sip it, or mix it into your routine, expecting that glowing, more even look.

Vitamin C does more than just improve the surface of your skin. According to a recent study from Tokyo Metropolitan Institute for Geriatrics and Gerontology, Vitamin C could play a bigger role in skin health. Researchers found it protects skin, and can also help rebuild it. The study revealed that Vitamin C helps to activate specific genes responsible for skin cell growth, thickening the skin from within by promoting DNA changes that allow cells to grow and multiply.

Here are some ways Vitamin C may support your ageing skin:

• Reactivate your skin’s youth: Vitamin C helps to turn on genes linked to skin renewal, potentially reversing thinning caused by age or damage.

• Strengthen from within: It boosts the production of keratinocytes, key skin cells that form the protective outer layer and maintain skin thickness.

• Encourage deep repair: By promoting DNA demethylation, Vitamin C supports deeper healing and cellular repair at the genetic level.

• Support longer-lasting results: Vitamin C’s effects go beyond temporary protection, it actively encourages your skin to rebuild itself over time.

• Mirrors youthful processes: This vitamin triggers biological processes similar to youthful skin, supporting both cell growth and natural skin defence mechanisms.

• Help ageing skin bounce back: Particularly helpful for mature or damaged skin, Vitamin C may restore resilience and slow the thinning that often comes with age.
