You might have chosen anti-ageing skincare products that contain retinol, not knowing about the potential consequences of using too much of the ingredient or maybe not even knowing that the ingredient is in your products. Dry, scaly skin is a common side effect of retinol-based products, since it sloughs off the top layer of skin to reveal new, brighter skin underneath. That means you'll experience flakiness
Read the ingredients of your skin care closely to determine if retinol is to blame for your dry skin. If so, take a night or two off between usages to use hydrating and soothing creams that won't irritate and will add moisture.
