Plaques can be divided into chloasma, freckles, age spots, etc. They are generally pigmentation on the skin, but the specific symptoms and performance of each kind of plaque are different and cannot be generalized.
1. Chloasma: Chloasma is common in middle-aged women, which will appear on the face as gray-black or yellow-brown patches as high as the skin surface, with different shapes and sizes, and the color of the patches will be aggravated by sunlight.
2. Freckles: related to genetic factors, mainly grow on the skin that is easily exposed to ultraviolet rays, belonging to small patches.
3. Age spots: Age spots are related to age and long-term sun exposure, and can grow on the face or hands, and red patches or edema may appear on the skin in this area.
It is usually difficult for patients to judge which type of plaque they belong to, so it is recommended to consult a doctor in time, do a systematic examination for a clear diagnosis, and follow the doctor’s instructions to carry out regular treatment.
