Can you use retinol and vitamin C together?
Use at different times
Usually not in the same routine. Most people get better results using retinol and vitamin C at different times.
Why
Both are strong, and using them back-to-back increases the chance of irritation. Vitamin C also works best at a lower pH than most retinol products.
How to use them
Use vitamin C in the morning (under sunscreen) and retinol at night. This gets you the benefits of both without layering them.
