Detailed answer

During puberty, hormonal fluctuations can stimulate an increase in melanin production. Melanin is responsible for giving color to the skin. When there is an excess of melanin, it can lead to hyperpigmentation, the darkening of certain areas of the skin. This is particularly common in individuals with darker skin tones. The surge of hormones, such as estrogen and androgens, can stimulate the activity of melanocytes, the cells that produce melanin. This increased activity can result in the development of dark spots, such as acne scars or melasma. It is important to use appropriate skincare products and practices, such as sun protection and gentle exfoliation, to minimize the appearance and prevent further hyperpigmentation during this period.
