Frontal freckles are related to endocrine disorders and decreased estrogen levels. The spot on the forehead is commonly known as chloasma. In addition, irregular menstruation and pregnancy can also cause chloasma. Traditional Chinese medicine believes that the generation of chloasma is related to the usual temperament, especially those with impatient personality are most prone to chloasma. The spots on the forehead are mostly senile spots, which are considered as benign intradermal tumors caused by aging skin and slow maturation of epidermal keratinocytes. However, the disease has familial inheritance, especially generalized senile plaque, which can be manifested as autosomal dominant inheritance. The occurrence of the disease is related to age and sex, and most of the female patients are perimenopausal women.
Suggestion: Be sure to avoid eating fish, shrimp, spicy and allergic foods, such as Flammulina velutipes, Auricularia auricula, figs, grapefruit and gray vegetables, which will aggravate the sensitivity to ultraviolet rays. Before you go out with long spots on your forehead, you should do a good job of sun protection and apply sunscreen. When the sun is strong, you can take an umbrella or a sun hat.
