Retinoids is an umbrella term used to describe a family of Vitamin A derivatives. Under which you have Retinoic Acid (tretinoin), retinaldehyde, retinol and retinyl esters - the last three are controlled conversion of retinoic acid, delivering all the benefits of vitamin A to the skin at different strengths.
The strongest being retinoic acid (which can only be prescribed), followed by retinaldegyde, then retinol (the super popular one), and ending with retinyl esters the weaker of retinoic acids.
Retinoids are incredible additions to your skincare routine, as they are known to be effective for improving skin tone and texture, reversing the signs of ageing, protecting the skin against UV damage, encouraging the cell turnover, and even helping with hyperpigmentation.
