1. Brightens skin

Brightens skin

For those seeking a brighter and more even complexion, Vitamin C is the hero ingredient you need. It is effective in diminishing the appearance of dark spots and brightening dull complexions. A study found that Vitamin C is useful in fighting pigmentation caused by UV rays. This ingredient inhibits melanin production, which helps to effectively lighten skin and areas of hyperpigmentation to give us a more even complexion.1

2. Fights free radicals

Other than its brightening properties, Vitamin C is known to be a powerhouse antioxidant. Free radicals are molecules that damage healthy cells and break down our skin’s collagen, leading to saggy skin. It is often caused by environmental aggressors such as harmful UV rays. Vitamin C is able to neutralise these free radicals, thus reducing damage and ensuring our skin remains healthy.

Vitamin C Helps Anti-Ageing

Vitamin C is not only great for brightening our skin, but it also helps with anti-ageing too. Vitamin C is found to help with anti-ageing by reducing the appearance of fine lines, wrinkles, and dark spots. Studies have shown that Vitamin C is effective in promoting collagen synthesis and helps increase collagen production in both young and aged human skin.2 Supple and glowing skin is not far away with the use of Vitamin C.

When should we use Vitamin C?

Most people incorporate Vitamin C in their night routine in the form of a serum. As our skin regenerates and repairs itself at night, applying Vitamin C before bed helps to boost these processes. Our skin is also able to better absorb and process the benefits of the ingredient at night.

You can also choose to add Vitamin C to your day routine too for added protection against harmful UV rays. If you’re applying a Vitamin C product in the day, remember to double up your sun protection by applying sufficient sunscreen after! Include it in both your AM and PM routine to maximise its benefits!
