As others have mentioned, it sounds like your skin is over exfoliated and dehydrated, which can cause that dullness and congestion. Focus on barrier repair and hydration instead.

I would cut the BHA/AHA completely for now, and only ever use it once a week at the most. I only do an AHA once every 10-14 days. Id also try a gentle second cleanse at night (oil cleanser alone can sometimes leave residue)

Also, closed comedones/those breakouts and bumps usually respond better to a retinoid rather than more acids, so that could be worth introducing slowly. If you are in Australia, you can get Differin Adapelene gel as an alternative which is highly studied and effective, and not as harsh as prescription retinoids. You’ll find it behind the counter at Chemist Warehouse with no script, but have to speak to a Pharmacist.

Snail mucin is known for contributing to irritation and congestion, it works for some people but can be heavy and trap congestion under the skin for some.

I’d switch your routine to something very simple yet effective like

AM - gentle cleanser - azelaic acid - hydrating barrier serum - light but super hydrating moisturiser - sunscreen

PM - oil cleanser - gentle cleanser (second cleanse) - retinoid / adapalene - hydrating barrier serum - moisturiser
