Detailed answer

Dehydrated skin lacks moisture, which can lead to an imbalance in the skin's natural barrier function. As a result, the skin may become dry, flaky, and rough. This can disrupt the even distribution of melanin, the pigment responsible for skin color, leading to an uneven skin tone. Dehydration can also make existing hyperpigmentation or dark spots appear more prominent. Additionally, when the skin is dehydrated, it may produce more oil to compensate for the lack of moisture, which can further contribute to clogged pores and the development of acne or blemishes. Therefore, maintaining adequate hydration is crucial for maintaining a healthy and even skin tone.
