Acne
Causes of Acne:
Excessive Sebum Production: Sebaceous glands produce an oily substance called sebum, which helps keep the skin lubricated. However, in individuals with acne, these glands produce an excessive amount of sebum, leading to clogged pores.
Bacterial Overgrowth: Propionibacterium acnes, a type of bacteria commonly found on the skin, can multiply in clogged hair follicles, leading to inflammation and the formation of acne lesions.
Hormonal Changes: Hormonal fluctuations, especially during puberty, menstruation, pregnancy, or hormonal disorders, can contribute to the development of acne. Androgens, a type of hormone, stimulate the sebaceous glands to produce more sebum.
Genetic Factors: Acne can run in families, suggesting a genetic predisposition to the condition. If your parents or siblings have had acne, you may have a higher likelihood of developing it as well.
Types of Acne:
Whiteheads and Blackheads: These are non-inflammatory acne lesions. Whiteheads occur when pores become clogged with sebum and dead skin cells, while blackheads result from oxidized sebum.
Papules and Pustules: These are inflammatory acne lesions. Papules are small, red, and tender bumps, while pustules are pus-filled lesions with a red base.
Nodules and Cysts: These severe forms of acne are deep, painful, and often leave scars. Nodules are large, solid, and painful bumps, whereas cysts are pus-filled, painful, and prone to infection.
