About *new* routine

My new routine after a major hormonal shift. my skin changed after spending the summer in a very humid country, after returning home, this winter my skin has been dryer than ever although my acne has improved a lot. I've changed all my products except my face wash and tried a ton of new things the past few months, and I haven't experience any irritation or acne. I've been inconsistent with my differin and still no longer have hormonal acne.
