The time it takes for cystic acne to subside on its own varies from person to person, taking about 4-8 weeks, or longer in some cases, and there are some cysts that do not subside on their own and may form secondary infections or even ulcers and scars. Acne, also known as pimples, is generally classified as acne, inflammatory papules, pustules, nodules, cysts, and scars. Cysts are a more serious type of acne with a cystic structure containing fluid or other components inside and located deeper in the skin, part of which can be elevated on the surface of the skin and another part of which cannot be seen but can be felt. Because of the deeper location, the absorption is slower (4-8 weeks) and some of the cysts may become infected, break out, sinus tracts, and scars due to inflammatory reactions and secondary infections. Therefore, for cystic acne it is recommended not to wait for it to subside on its own, but to treat it promptly under the guidance of a dermatologist. It is recommended that after the occurrence of cystic acne, you must not casually squeeze or pick with your hands to prevent aggravating the infection, which in turn makes treatment more difficult and affects recovery.
