Who has never heard of Vitamin C? Impossible to see a raised hand. We have always heard about the great benefits of this vitamin which is essential for the efficiency of the immune system, for optimal iron absorption and for the healthy maintenance of our organs and tissues. Vitamin C or L-ascorbic acid is a water-soluble vitamin that is not produced by our body and is not even storable; for this we must take it every day through food with a balanced diet. It is also an excellent cosmetic ingredient that we can apply to the skin on a daily basis for its health. But exactly what role does it play in relation to our skin?
When we talk about Vitamin C in cosmetics we are mainly referring to the properties and benefits it brings to the skin of our face.
It has antioxidant, photo-protective and illuminating properties; its constant use therefore stimulates the production of collagen helping to prevent skin aging, the appearance of wrinkles and fine lines. It also inhibits the production of melanin resulting in a depigmenting effect. Let's see its effects in detail.
Lightening - Decreases hyperpigmentation
Vitamin C, once penetrated into the epidermal cells, exerts an antimelanogenic effect, i.e. it significantly reduces melanin (black, brown, reddish pigments – “from the ancient Greek μέλας mèlas = black”) present in the skin and its biosynthesis .
This occurs through the inhibition of the enzyme tyrosinase, a fundamental enzyme for the biosynthesis of melanin, which occurs starting from tyrosine in melanocytes, epidermal cells responsible for the biosynthesis of melanin. In practice, it helps to lighten age-related spots or due to incorrect sun exposure but also acne scars.
It protects the skin from oxidative stress induced by UV rays
In fact, UV radiation favors the massive production of free radicals, highly unstable and reactive molecules which cause oxidative stress and damage DNA, lipids and proteins. The lipids of the stratum corneum of the epidermis are particularly susceptible to the action of free radicals which they induce a deconstruction, with consequent premature ageing.
Stimulates the production of collagen
Vitamin C is essential for the production of collagen. Collagen is a protein present in large quantities in the dermis, where it performs an important support and structure action for the skin. As age progresses, collagen synthesis inevitably decreases and this leads to a reduction in skin tone and the appearance of the first wrinkles. That's why stimulating the production of new collagen is essential for firm and youthful skin.
Is it better to use the serum with Vitamin C if you have dry or combination/oily skin?
Thanks to the properties we have just seen, Vitamin C can be used in the skincare routine of all skin types. From the more mature ones to the younger ones, from the driest ones to the fat and impure ones, everyone can benefit from its use.
For all these reasons, the serum with Vitamin C can also be used on very young skins, aged 18-20 and up.
When to use it in your beauty routine
The application of the Vitamin C uniform booster serum has no particular contraindications, it can be applied in the morning or in the evening, depending on your preferences.
