Will hyperthyroidism cause the skin to become lighter after recovery?
Disease description:
My best friend previously had hyperthyroidism, and her overall condition was quite poor, with somewhat dull skin. Recently, her hyperthyroidism has mostly improved, but her skin still appears slightly dark. She really wants her skin to become fairer and wonders whether the skin will automatically lighten after hyperthyroidism has resolved.

Hyperthyroidism refers to an overactive thyroid gland. After recovery from hyperthyroidism, the skin generally does not become lighter. The detailed explanation is as follows:
Hyperthyroidism is a condition caused by excessive secretion of thyroid hormones, leading to an increased metabolic rate throughout the body. During treatment, thyroid hormone levels return to normal, the metabolic rate stabilizes, and melanin synthesis and metabolism in the skin also return to normal, bringing the skin color close to its usual tone. However, skin color is influenced by multiple factors, including genetics, degree of sun exposure, skin disorders, anemia, and abnormal liver function. Hyperthyroidism itself typically does not directly cause skin darkening; therefore, after recovery, skin color generally does not significantly lighten.
Although skin may not necessarily become lighter after recovery from hyperthyroidism, skin condition can be improved through other means. For example, maintaining skin cleanliness by choosing suitable facial cleansers and skincare products; practicing sun protection to prevent ultraviolet radiation damage; and ensuring adequate sleep to aid skin repair and regeneration.
