The Derma Corner: What you need to know about retinoids, according to a dermatologist

When we talk of retinoids, we mean the big group of vitamin A derivatives which includes the non-potent forms like retinol, retinaldehyde, and retinyl palmitate found in skincare and the medical-grade forms like tretinoin, adapalene, tazarotene and the oral isotretinoin. These are typically prescribed for acne. Scientifically speaking, they work by binding to the retinoic acid receptors in the skin cells which will increase skin cell turnover, increase production of dermal collagen, minimize pores, and brighten hyperpigmentation.
