Can you use retinol with vitamin C?
Yes. The idea that vitamin C and retinol cancel each other out isn't supported; splitting them, with vitamin C in the morning and retinol at night, is mostly about comfort and timing.
Why
Pure vitamin C (L-ascorbic acid) has few true incompatibilities, such as benzoyl peroxide and copper, and a cream containing both retinol and vitamin C was used twice daily for months in clinical studies. Both can sting on sensitive skin, so layering an acidic vitamin C serum with retinol may add to dryness. Vitamin C's antioxidant benefits are most useful in the daytime, while retinoids break down in light, which makes a morning and night split practical.
How to use them
Apply vitamin C in the morning before sunscreen and retinol at night. If your skin is comfortable with both, using them together at night is fine too.
