Detailed answer

During menstruation, the levels of hormones such as estrogen and progesterone fluctuate, which can impact the skin. These hormonal changes can lead to decreased blood flow to the skin, resulting in a dull and sallow appearance. Additionally, the hormonal shifts can increase sebum production, leading to oily skin and clogged pores. The combination of reduced blood flow and increased sebum production can contribute to the sallow complexion experienced during menstruation. It is important to maintain a consistent skincare routine, which includes proper cleansing, exfoliating, and moisturizing, to help minimize the effects of hormonal fluctuations on the skin.
