In addition to its well-known whitening function, vitamin C also has a good antioxidant effect.
It is a natural antioxidant that can supply electrons, neutralize free radicals, and protect intracellular structures from oxidative stress.
It achieves antioxidant effects through the redox process of forming ascorbic acid free radicals, which then turn into dehydroascorbic acid and finally restore to L-ascorbic acid.
In simple terms, vitamin C can “defeat” oxygen free radicals in dermal cells and help you tighten your skin. At the same time, vitamin C can also stimulate collagen production.
The higher the concentration of vitamin C, the less likely you are to age?
After knowing the benefits of vitamin C, many people’s first reaction is: I will use more vitamin C!
Wait, understand the following three points about vitamin C to better achieve a “win-win” situation with vitamin C:
1. Absorption
The skin has its own ideas. Applying vitamin C 2 to 3 times a day is enough. Applying more will be a bit wasteful.
The topical concentration of vitamin C is generally divided into 10%, 15% and 20%. Different skin types are suitable for different concentrations. Before using vitamin C, understand your own skin first.
2. Penetration
Vitamin C itself has strong ability. If there is an efficient formula, it can help vitamin C to be absorbed through the skin to the greatest extent, and then further exert its powerful effect.
3.Types
The most famous vitamin C is L−（+）−ascorbic acid, which does not lose its effectiveness due to the change of form.
Although its stability is average compared with A6P (ascorbic acid-6-palmitate) and SAP (sodium ascorbyl phosphate), L−（+）−ascorbic acid is still a leader in the field of skin care because of its effectiveness at a certain concentration, and many brands choose it.
If there is a good stabilization system (such as an encapsulation system) or a reasonable formula (combined with other active ingredients to maximize the effect),L−（+）−ascorbic acid is a very good choice for skin care.
