Need help with acne before top surgery

i have really sensitive/thin skin, and in less than 2 months i'm getting top surgery. However, i need to have the acne/acne scabs on my chest healed before i get surgery because it can effect my ability to even qualify..... I was on antibiotics for a week awhile ago, but had to stop because i was vomiting every single time i took them (no matter how much food i took with it... it just makes me throw up), so i had to stop taking it. i was wondering if there's any specific skin care products that y'all would recommend or anything else? rn im just alternating between Vitamin E cream (which usually helps me heal rlly fast but it's not doing much), bliss body acne spray (i have no idea if this is a good product or not i just started using it, if it's not pls tell me), and bliss acne spot treatment, if that helps
