Hydration
As the most water dense molecule, vitamin C prevents skin cells from losing their natural hydration. It also helps the skin absorb hyaluronic acid, which boosts collagen and keeps skin plump and hydrated. Vitamin C can help reduce sun damage by inhibiting the production of enzymes that cause oxidation and also quells redness and hyperpigmentation by blocking the formation of melanin in the skin, says dermatologist Anna Guanche, founder of Bella Skin Institute in Calabasas, California.
Antioxidant
As well as brightening a dull complexion and fading dark spots, vitamin C acts as a powerful antioxidant to protect against free radical damage. These are destructive high energy particles that come from pollution, smoke, dust and UV rays from the sun. Free radicals are the leading cause of premature skin-ageing, so it’s important to use ingredients that fight them.
When used topically, vitamin C neutralizes free radicals, which prevents oxidation and sagging skin. It also blocks abnormal production of pigmentation, which helps to even skin tone and fade dark spots.
Brightening
When it comes to treating common complexion concerns like uneven skin tone, rough texture and fine lines, vitamin C is among the best treatments you can add to your regimen. This is thanks to its ability to brighten and soothe skin.
As an antioxidant, one of vitamin C’s key benefits is its ability to scavenge and neutralize free radicals caused by normal cellular processes and environmental stressors (like pollution and UV rays). This helps prevent the oxidation of collagen and elastin, which leads to fine lines, wrinkles, dullness and discolorations.
