Remove freckles and nevus

Age spots

The cause of age spots is similar to that of other spots. It is mainly caused by the damage of ultraviolet rays in the sun to the skin. Age spots are also due to the cumulative damage caused by ultraviolet rays to the skin, causing melanin to be produced at the bottom of the skin, which then slowly emerges from the bottom of the skin over time, forming common spots. In addition, benign keratin hyperplasia appears on the skin surface, and excess keratin accumulates at the location of age spots, making the surface of age spots rough and protruding.

Flat warts

Flat warts are viral infections and are contagious. If you scratch them a little, the virus can inoculate itself and grow in the direction of the scratches. Flat warts are a chronic skin disease caused by infection with the human papillomavirus (HPV). They commonly occur on the face or back of hands of teenagers. They appear clinically as skin tags, with flat and smooth raised surfaces that appear scattered or densely. It comes out of the skin and feels hard, about the size of a grain of rice or a mung bean, and is light brown in color. Most of them do not pose any further harm to human health. It is better if they can be treated early to avoid leaving scars or pigmentation.

mole

Moles generally do not cause discomfort to patients. Common benign changes include:
1) Hormones: Moles all over the body change together and usually become larger. They often occur during pregnancy and adolescence, oral medications, chemotherapy, immunosuppression, etc.
2) Local changes: Several moles on the hands turn black together due to sun exposure, or changes caused by skin diseases.
3) Changes in a single mole: Moles also have hair follicles, and folliculitis may occur, sometimes even accompanied by acne and inflammation.
