Retinoid vs Retinol?

RETINOID is an umbrella term for all Vitamin A. Retinol is part of the Retinoid cascade. In order of strength (strongest to weakest) Tazarotine tretinoin Retinal Retinol Retinol Palmitate Retinol esters. As you go higher up the cascade it gets more effective BUT irritation is also higher and some are unable to tolerate them. Higher dose not equate effectivity. As for need, ill ask back, whats your skin concern first?

From what my friend told me that retinol & retinoid are similar it just that retinoid are more powerful. you can read more here https://www.healthline.com/health/beauty-skin-care/retinoid-vs-retinol
