What is the difference between the effects of Vitamin C and those of Resveratrol on the skin?

It is true that these two substances are recognised for their excellent antioxidant properties. However, some nuances can be made regarding their use.

Derived from Japanese knotweed, a plant from East Asia used in traditional Chinese and Japanese medicine, resveratrol is primarily recommended to combat oxidative stress and the damage to cells caused by free radicals. As a reminder, these are unstable molecules that are highly reactive and produced in excess by various factors such as stress, smoking, pollution, poor diet... They destroy the cells and healthy proteins of the skin, accelerating its ageing and the appearance of ageing signs such as wrinkles and/or pigmentation spots. Resveratrol works upstream by blocking the formation of free radicals and downstream by neutralising existing free radicals. It thus has a dual preventive and corrective action against sources of oxidation, which helps to limit the premature ageing of the skin.

Vitamin C also effectively combats oxidative stress, but it is primarily recommended for its impact on the skin'sradiance and uniformity of complexion. Indeed, several studies have demonstrated its brightening power when applied topically, which even helps to combat hyperpigmentation, a skin disorder that can occur at any age and is characterised by brown spots on the skin's surface. Furthermore, it stimulates the synthesis of collagen in the skin, enhancing its firmness.
