[Product Question] Started using 2% BHA and Vitamin C. Skin is red and dry, is this normal?

Beauty Tips For Body Care
Hey guys,I started using BHA and Vitamin C two days ago. The first day I used both morning and night. The second day, I only used the BHA at night because It made my foundation application horrible in the morning (dry and flaky). I think I will continue to do this.My skin type is oily/combo. Prior to these products, I simply used olive oil to wash my face and a moisturizer.Now, my routine is: Cleanse with Olive oil, apply BHA (wait 15 mins), Apply Vitamin C (Wait), Moisturizer/Sunscreen.Anyways, after applying these products my skin feels very tight and dry. It also looks very red. I already have a pimple on my chin, and I usually only get pimples around my period. Is this normal? Should I do something different? Thanks!
