Why do people with anorexia and secondary amenorrhea suffer from acne?

Chest acne is treated in a similar manner as facial acne and the treatment options have be quite comprehensively discussed elsewhere in this forum which you can refer to. They include topicals, oral antibiotics and oral isotretinoin. The main difference is that chest acne tends to respond more slowly than facial acne and may be more prone to cause thickened scar (acne keloids). Also acne mimics such as Malassezia folliculitis need to be excluded.

Hi, There are much more effective and proven treatments for acne scars such as subcision, fractional lasers and micro-needling that you should consider first. Rejuran Healer may be the current craze for anti-ageing treatment but it is more targeted at maintaining skin health by stimulating natural collagen synthesis in the upper dermis.
