Hi i have bought a few products (already have facial wash and scrubs and masks but very poor routine and don't use things right)
I have open pores and some acne. Starting to age. Aged early 40s
I have the
salicylic acid serum
Niacinamide
Glycolic acid and zinc moisturiser
I want to start using them and also but the retinol (I know to start very low and sparingly)
But I am at a loss do I apply the glycolic after cleansing and then the salycilic serum and then moisturize??
Please help
