Fatty skin

Oily skin can be linked to a genetic predisposition to produce the hormone dihydrotestosterone (DHT) excessively, leading to more sebum being produced in the skin. Sebum is an oily, waxy substance that keeps the skin balanced and helps retain moisture. However, excessive sebum production can become problematic. It can enlarge pores, and when trapped, sebum can mix with dead skin cells and bacteria on the skin's surface, leading to pimples. The Climate Another common trigger for oily skin is hot summer weather. Heat and humidity can lead to an increase in sebum production. You might be trying to address your oily skin by cleansing four times a day or exfoliating too often. But these methods strip the skin of its natural oils and disrupt the skin's barrier function. Hormonal Fluctuations: Excessive Sebum Production Hormones can still affect your skin, even after puberty. During pregnancy, menopause, or the menstrual cycle, hormonal fluctuations can cause excessive oiliness and pimples. According to Foreo.com: “Androgens are the hormones primarily responsible for sebum production, and sometimes they can fluctuate, resulting in an increase in sebum production. This often happens during puberty, just before menstruation, during pregnancy, and during menopause.”
