The virtues of vitamins in cosmetics: benefits for the skin

The different types of vitamins

Les provitamines

Issues of food, provitamins are substances that can be transformed into vitamins by the body. This is for example the case of beta-carotene, which is found in carrots, dandelions, spinach, parsley, apricots and various other foods. It is a precursor of the vitamins A which plays, among other things, an important role in preventing cell oxidation and vision.

The body converts only the substances it needs into vitamins, which means that even when you consume too many, the provitamins present no risk of overdose.

THE provitamins are precursors of vitamins. To transform into the latter, they must first be converted by enzymes. This is how provitamins become beneficial to the body. Since the body only converts the necessary amount of provitamins into vitamins, they cannot cause poisoning. Examples of provitamins: beta-carotene, precursor of vitamin A, and 7-dehydrocholesterol (cholesterol), converted to vitamin D3 (cholecalciferol) in the skin when exposed to the sun.

water-soluble vitamins

As their name suggests, these water-soluble vitamins dissolve in water: that of our body and cells or, for example, in that of cooking.
Eliminated through urine, water-soluble vitamins accumulate very little in the body. Their consumption can therefore be regular, because the body evacuates what is not necessary while retaining only what it needs. Here again, there is therefore no risk of overdose.

THE vitamins B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 ​​(pyridoxine), B8 (biotin), B9 (folic acid), B12 (cobalamin) and C (ascorbic acid) belong to the water-soluble vitamin family.

fat soluble vitamins

This family of vitamins dissolves in fate, which means that the body has the capacity to store them. You must be careful not to consume them in excess quantities, as they then accumulate in the organs (liver, etc.), which can be risky, even fatal, in the event of an overdose. For example, the polar bear feeds mainly on seal fat, which is very rich in vitamin A. The bear's liver stores this vitamin. If a human were to consume even a single tablespoon of polar bear liver, it would be fatal.

THE vitamins A, D, E and K are fat-soluble.

Vitamins and oxidation

Oxidation of vitamins occurs when they are exposed to air, light, heat or even water. THE vitamins A, C and E are the most sensitive of them.

It is therefore an essential parameter for cosmetics, especially when choosing packaging. It is for this reason in particular that at Grangettes Switzerland, we chose aluminum and glass bottles, considered the best option to prevent oxidation of formulations. In fact, they do not allow air or light to pass through and are more suitable than plastic to protect against heat. And of course, they are ecological, because 100% recyclable.

Finally, antioxidants such as vitamin C, vitamin E and selenium help prevent the oxidation of vitamins, helping to neutralize free radicals that can damage them.
