Pustules on face started just 4 days ago after joining gym

I had a pretty clear skin. I started working out heavily few days back and I’ve been getting this all over my face even though I do my regular skincare. AM- toner, niacinamide, hyaluronic acid, minimalist moisturiser, lacto calamine sunscreen PM- moisturiser, glycolic acid (twice a week)or tretinoin (twice a week) , moisturiser [sandwhich method] Any suggestion is welcomed The pustules comes on and off but currently it’s at a bad state. When the pustules goes away it leaves a bumpy skin there. Help a girl out 😭
