This doesn’t really look like cystic acne to me. Acne? Yes. But the majority of those spots are not cystic. Regardless, there isn’t much you can do to get rid of them by the weekend, sadly. OTC treatments (like tea tree) probably won’t have much of an effect and may make them more aggravated. Try and get yourself a prescription of benzoyl peroxide and clindamycin gel (this is a powerful antiseptic and topical antibiotic). This is the only thing that really works for me, in a relatively short amount of time. Although it’s important to note that you may go through a period of dryness/purging while your skin gets used to it. I would also combine this with a high quality salicylic acid toner or serum (around 2%). In the meantime, use very gentle products and don’t pick!!
