FAQ about vitamin c and its derivatives

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

Ascorbic acid is the form of vitamin C that is the purest. While it is highly effective, the same applies to other forms, such as ascorbyl glucoside, which are more stable and better tolerated by sensitive skin.

Can one use vitamin C in the morning?

Yes, it is possible. Contrary to a fairly widespread misconception, the vitamin C is not photosensitising.

Can vitamin C combat hyperpigmentation?

Yes, vitamin C can inhibit tyrosinase, the enzyme responsible for melanin production, which helps to reduce brown spots and even out the complexion.

How long does it take to observe results from vitamin C?

The duration of action of vitamin C depends on the specific concern: if it is oxidative stress, only a few days, but in the case of brown spots or wrinkles, it can take several months.

Can vitamin C replace sunscreen?

No, vitamin C cannot replace sun protection, even though its antioxidant action helps to protect the skin from UV radiation.

Is vitamin C incompatible with retinol?

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

What are the effects of vitamin C on skin laxity?

By neutralising 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, pure vitamin C can be poorly tolerated by sensitive skin. This is one of the reasons why vitamin C derivatives are often used in cosmetics.

Does vitamin C help to reduce dark circles and under-eye puffiness?

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

Does vitamin C have beneficial effects on hair?

Yes, vitamin C is beneficial for hair. Although more studies are necessary to confirm this, some research suggests it may slow hair greying and promote hair growth.
