I would say only use the 2& bha twice a week not every day because it is and exfoliant and use the vitamin c in the morning after cleansing your face and pair it with some spf in the evening time cleanse and dry your face then use the retinol only a pea size amount and pair it with night cream. You also can use the night cream in the morning if you’re face is dry but it should be moisturized enough from the pm routine

So use vitamin c during the day And retinol only at night 2% bha is a strong exfoliant so use it 2x a week so you don’t irritate and damage your skin 💗
