Do not use at the same time as AHAs, BHAs, and retinols. Low concentrations of AHA and BHA can be used as a nightly routine. One night I take vitamin C and the other I take retinol. Or take vitamin C in the morning and AHA, BHA, or retinol at night. People with acne-prone skin should be careful when using vitamin C. Vitamin C can cause breakouts. It is better to do a patch test beforehand.
Optimal usage
L-ascorbic acid is a powerful form of vitamin C that becomes unstable when exposed to light, so some doctors recommend using it at night. However, it also protects from UV rays, so you can apply sunscreen over it and use it during the day. Other forms of vitamin C can be used during the day and at night.
After washing your face, apply 3-4 drops of vitamin C serum, followed by a moisturizer. Apply sunscreen over it. It takes approximately 6 to 8 weeks to see results.
