What is Vitamin C?

Vitamin C is also known as ascorbic acid. It promotes the synthesis of collagen in the skin and helps prevent photoaging caused by ultraviolet rays. As we get older, its presence diminishes.

Way into the skin

When we apply vitamin C to our skin, it has to pass the superficial layers of the skin to reach deeper ones. We can facilitate its penetration submitting the skin to an exfoliation.


Some studies show the improvement of skin lines after applying vitamin C for at least 12 weeks at concentrations between 3 and 10%, probably due to an increase in collagen production and a decrease in the destruction of elastin fibers.

How does it work?

Vitamin C limits the damage to the skin caused by UV radiation. Its antioxidant action diminishes the damage produced by the free radicals of UV light (decreasing the damage on the DNA of the skin). It seems that the topical use of vitamin C is more effective than the oral ingestion. However, studies suggest that its oral use could protect against skin cancer by improving the tolerance to UV light.

Molecular challenge

However, the vitamin C molecule is unstable. It undergoes a degradation that makes it less effective. Therefore, many “vacuum” containers are used in dermatocosmetics. Moreover, this is why antioxidants like ascorbylpalmitat (or ascorbate phosphate) are usually added to improve its formula.
