Hi so I'm kind of an amateur when it comes to how to look after skin and what I should do, I've been looking up AHA and BHA recently and discovered BHA would actually be better for oily, blackhead, whitehead prone skin. My question is should I replace the Pixi Glow Tonic (AHA) at AM and PM with something like Paula's Choice 2% BHA Liquid Exfoliate or just use the BHA at PM and AHA at AM? 

My skin type I would say is Oily/Combination, if I were to wash my face with just water or come out of the shower without using moisturiser it would go dry and tight, but later on in the day it would start to become oily, and especially when I wake up in the morning its quite oily and I might have 1 or 2 whiteheads which made me think using the BHA at PM might be a good idea?

Some people told me to use a moisturiser with SPF but I never thought this was necessary much as I live in UK and its quite hard finding one especially when the Aveeno is so nice 

Current Routine: 

AM

CeraVe Hydrating Cleanser

Pixi Glow Tonic (AHA)

Aveeno Daily Moisturising Lotion

PM

CeraVe Hydrating Cleanser

Pixi Glow Tonic (AHA)

Aveeno Daily Moisturising Lotion

Thanks.
