A lack of estrogen can cause which of the following symptoms?

A lack of estrogen can lead to dehydration and possible hyperpigmentation due to the hormone's role in maintaining skin hydration and elasticity. Estrogen is crucial for the production of collagen and the regulation of moisture levels in the skin. When estrogen levels are low, there can be a decrease in the skin's ability to retain moisture, leading to dehydration. This lack of hydration can also make the skin more susceptible to damage from environmental factors, which may contribute to hyperpigmentation as the skin responds to stress or injury by producing more melanin in certain areas.

This connection highlights the importance of estrogen in skin health and emphasizes why symptoms related to dehydration and uneven skin tone, such as hyperpigmentation, can be linked to its deficiency. Understanding the role of hormones in skin conditions is vital for estheticians when assessing and treating various skin issues.
