Vitamin C

Vitamin C, or ascorbic acid, is a potent antioxidant that plays a key role in skin health. It aids in protecting against external aggressors such as pollution and UV rays, stimulates collagen production, and reduces the appearance of pigmentation spots. When used regularly, it brightens the complexion and improves skin texture. Learn more here about vitamin C and its various forms.

FAQ about vitamin c

What is the difference between ascorbic acid and other forms of vitamin C?

Ascorbic acid is the vitamin C form that is the purest and most potent, but other forms, such as ascorbyl glucoside, are more stable and better tolerated by sensitive skin.

Can we use vitamin C in the morning?

Yes, this is possible. Contrary to a widely held misconception, vitamin C is not photosensitive.

Can vitamin C combat hyperpigmentation?

Yes, vitamin C can inhibit tyrosinase, the enzyme responsible for melanin production, which aids in reducing brown spots and evening out skin tone.

How long does it take to see results with vitamin C?

The duration of action of the vitamin C depends on the targeted issue: if it's oxidative stress, only a few days, but for brown spots or wrinkles, it takes several months.

Can vitamin C replace sun protection?

No, vitamin C cannot replace sun protection, even though its antioxidant action contributes to protecting the skin from UV rays.

Is vitamin C incompatible with retinol?

Contrary to some misconceptions, vitamin C can be combined with retinol, but this combination may prove slightly irritating for sensitive skin.

What are the effects of vitamin C on skin laxity?

By neutralizing free radicals and stimulating collagen synthesis by fibroblasts, vitamin C helps to prevent skin sagging.

Is vitamin C suitable for sensitive skin?

Due to its acidity, vitamin C in its pure form may not be well-tolerated by sensitive skin. This is one of the reasons why vitamin C derivatives are often used in skincare products.

Does vitamin C help to reduce dark circles and bags under the eyes?

Some studies suggest that vitamin C may help fade brown under-eye circles due to its brightening properties. However, it has no effect on vascular under-eye circles.

Does vitamin C have hair benefits?

Yes, vitamin C is beneficial for hair. While more studies are needed to confirm this, some research suggests that it may slow down hair graying and enhance hair growth.
