"If you want to know my favorite retinol, and the one that most of my patients use now and absolutely love, it's the AlphaRet Overnight Serum from SkinBetter Science. The regular one has lactic acid, retinoic acid, and glycolic acid in it, so it has some exfoliating benefits plus that retinol, and it's available over the counter. The main benefit to AlphaRet is the very low level of irritation."

"It improves hydration as well as the bioavailability of the retinoid, since they're made together. This is a really awesome serum. Texture-wise, it's very creamy and very luxurious, but it's not over the top heavy. I just use a pump or two all over my face and neck, and it spreads really nicely. So if you're looking to splurge on a retinoid product, this is one that I highly recommend, especially if you have rosacea or sensitive skin."
