Answer :
Final answer:
Acne, or pimples, indicate acute tissue texture change. Commonly occurring during puberty due to hormonal changes, they form when overproduction of sebum and keratin block hair follicles. This can cause infection and potential scarring.
Explanation:
Pimples or acne is an indicator of acute tissue texture change. Acne is a skin disturbance that typically occurs on areas of the skin that are rich in sebaceous glands such as the face and back. It is most common during puberty due to associated hormonal changes, but can also occur in infants and continue into adulthood. Hormones like androgens stimulate the release of sebum, and an overproduction and accumulation of sebum along with keratin can block hair follicles, leading to acne. This is initially indicated by a white plug that turns black when the sebum is oxidized by exposure to air. The infection by acne-causing bacteria such Propionibacterium and Staphylococcus can lead to redness and potential scarring due to the natural wound healing process.
