Vitamin A Overview
Vitamin A Overview — a family of fat-soluble compounds, known as retinoids, that includes retinol, retinaldehyde, retinyl esters, and prescription forms like tretinoin. In skincare, vitamin A derivatives are studied for their influence on skin cell turnover and the appearance of fine lines, uneven tone, and texture.
Key points
- Vitamin A in skincare refers to retinoids, which range from gentler cosmetic forms like retinyl esters and retinol to prescription-strength options.
- Retinoids are converted in the skin toward retinoic acid, the active form that interacts with cellular receptors.
- They are widely researched for supporting the look of smoother texture and more even tone over time.
- Retinoids can cause dryness or irritation during early use, and they increase sensitivity to sunlight.
Frequently asked
What is the difference between retinol and retinoic acid?
Retinol is a milder over-the-counter form that the skin converts into retinoic acid, the active form that is also available directly by prescription.
Should sunscreen be used with vitamin A products?
Yes, retinoids can make skin more sensitive to the sun, so daily broad-spectrum sunscreen is recommended when using them.
