How retinol works in cosmetics
Retinol has several characteristic features that allow it to be considered one of the most active and effective components for many years.
- Due to its small molecular size and lipophilicity (it is a fat-soluble element), retinol overcomes the lipid barrier of the skin and penetrates the epidermis.
- Retinol stimulates active cell division of the basal layer of the epidermis, that is, it accelerates the renewal of the cellular composition and, in addition, affects not only keratinocytes, but also deeper dermal structures – fibroblasts, melanocytes, which are responsible for skin elasticity and pigmentation uniformity.
In general, retinol has a powerful renewing and tightening effect on the skin.
However, this miracle substance has a number of features that must be taken into account when applying.
- Retinol products can cause active flaking, redness, and dryness. Therefore, it is extremely important to follow the manufacturer’s instructions, which usually recommend introducing care with retinol, gradually increasing the frequency of use.
- Retinol products increase the photosensitivity of the skin, therefore they are usually categorized as night care, requiring a high SPF sunscreen every morning for the duration of the application.
- Retinol is an unstable ingredient, it oxidizes quickly. Of particular importance is the packaging, which must isolate the formula from contact with air.
