PIH routine + mild acne

I dont use this particular Snail Cleanser. I couldnt find the TiaM Snail and Azulene cleanser. Its really mild and never gives me a tight feeling.

I'm waiting for Melano CC vit c serum to add to the morning, my skin seems to tolerate BHA well, provided I slaver mucho mucho moisture after. Wake up with no irritation and calm skin.

Any other suggestions?

I have little weird bumps under my lip and nose, does anyone know what it is?

Ps. Is retinol an absolute must?
