What are the effects of increased activity of sweat and sebaceous glands during adolescence?

During adolescence, both sweat glands and sebaceous (oil) glands become more active due to hormonal changes, particularly increased androgen hormones. Sweat glands produce more perspiration, which can lead to body odor, especially in areas like armpits and feet, making regular bathing and use of deodorants important. Sebaceous glands produce more sebum (oil), which can make skin and hair oilier. When excess oil combines with dead skin cells and bacteria, it can clog pores, leading to acne (pimples and blackheads), particularly on the face, chest, and back. These changes are normal parts of puberty and can be managed through good hygiene practices, regular face washing, appropriate skincare, and in persistent cases, consultation with a dermatologist.
