Avoid combining retinol with potent AHAs/BHAs like glycolic or salicylic acid. Using them simultaneously significantly increases irritation risk. Instead, alternate their application–use retinol one night, an AHA/BHA the next. This minimizes irritation while maximizing benefits.
Vitamin C and Retinol: A Powerful Duo (With a Catch)
Many find success using vitamin C and retinol together. However, the best approach is to apply vitamin C in the morning and retinol at night. This prevents potential inactivation of each ingredient. Choose a stable vitamin C derivative like tetrahexyldecyl ascorbate for better compatibility.
Hyaluronic acid is a great addition to any retinol routine. Apply it after your retinol serum to lock in moisture and soothe potential dryness. Niacinamide can also help minimize retinol irritation and enhance its effects; apply it after retinol. Avoid combining retinol with benzoyl peroxide, as this combination can be overly drying and irritating.
