FAQ about vitamin c

What is the difference between ascorbic acid and other forms of vitamin C?
Ascorbic acid is the most vitamin C pure and potent form, 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 photosensitising.
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 in the case of brown spots or wrinkles, it takes several months.
Can vitamin C substitute 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 sagging?
By neutralising free radicals and stimulating collagen synthesis by fibroblasts, vitamin C aids in preventing 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 assist in reducing dark circles and bags under the eyes?
Some studies suggest that vitamin C may help to diminish 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. Although more studies are needed to confirm this, some research suggests that it could slow down hair greying and enhance hair growth.
