Should I use bakuchiol and a retinoid (retinol/retinal) together?

Usually there's little reason to stack them. Bakuchiol is a plant-derived ingredient that acts as a gentle, retinol-like stand-in: it supports the look of firmness and more even tone by nudging the skin's own signals, rather than converting into active vitamin A in the skin the way a retinoid (retinol or retinal) does. Because their roles overlap, layering bakuchiol on top of a retinoid tends to raise irritation with little added benefit. Many people pick bakuchiol as the calmer option instead of a retinoid, or use one rather than layering both at once. If your skin is sensitive, bakuchiol paired with soothing, hydrating ingredients (such as niacinamide, hyaluronic acid or ceramides) is often the gentler route.
