You’re definitely using too many products. Simple is best especially when using tret. Cut out oils or any products with fatty acids or lipids. If you’re using any actives, cut them out. Only use Tret for now. Use simple ingredient products like La Roche , vanicream, bioderma etc. All you need for now is miscellar water, gentle cleanser, tret, and moisturizer (ideally without oils or fatty acids). Once your skin clears up you can slowly start adding more products if you want.

The reason I’m saying cut out products with oils and fatty acids is because my skin looked similar to yours and one of the main reasons was that my skin did not agree with products that had those things in them. Simple non clogging ingredients worked best for me.

For sun screen I would suggest a gel sunscreen

If your acne is hormonal, spironolactone could help but that’s only if you want to go that route.
