Can I use vitamin C, niacinamide and retinol together?

Many people can, but introduce one at a time and patch-test. Retinol and vitamin C are commonly split between night and morning. If your skin stings or flakes, scale back.

Is retinol safe during pregnancy?

Retinoids are generally avoided in pregnancy, so ask your doctor or midwife before using any retinol product. This site gives general product information, not medical advice.
