In the 23 years I’ve been researching and writing about skin care, retinol has evolved a ton. But one thing hasn’t changed: It’s still confusing. There are some straightforward questions, like “Are prescription retinoids more effective than the stuff at Sephora?” and “How long should it take for your skin to get used to retinol — and what if it never does?” And then there are more complicated ones, like “What’s the difference between retinyl palmitate and retinaldehyde?” and “Is retinyl sunflowerate really a thing now?” Leave questions like that (or any others you have, plus your experiences) below, and I’ll answer them here on Tuesday, December 5.
