Hey Ndapanda , Gycolic acid should only be used 2-3 times in a week because it’s a chemical exfoliant and it helps with hyperpigmentation But only evening time and not during morning routine as your skin can be irritated from exposure of the sun. And Niacinamide serum it’s not a hydrating serum ,it reduces large pores if you have them on your face skin, helps with fine lines and especially it helps with skin tone and dark marks. However if you’re looking for a hydrating serum you will need Hyaluronic acid serum.
