Greetings. Thyroid issues per se commonly do not cause acne. However may be involved in patients who have concomitant pcos problem. However look at more common reasons of worsening of acne like use of make up/ cosmetics/ pollution / unhealthy junk diet etc. See a qualified dermatologist near you and discuss the issue with him in detail with direct examination of your problem. Further queries may be sent on follow up messaging. Warm regards
