Long arm spots are considered to be related to factors such as prolonged sun exposure and skin aging, which can be alleviated by strengthening sun protection, drug intervention and physical therapy.
1. Strengthening sun protection: long-term exposure to ultraviolet rays in the sunlight on the arm area may cause skin melanin aggregation and increase, thus causing the symptoms of arm spotting, so it is necessary to do a good job of sun protection in order to reduce the incidence of arm spotting.
2. Pharmacological intervention: topical application of vitamin A cream, hydroquinone, tretinoin and other drugs can play a role in inhibiting melanin cell metabolism and chemical exfoliation, enhance the effect of local discoloration, and improve the symptoms of arm spotting.
3. Physical therapy: patients can also be treated with laser therapy to remove the pigmentation on the skin surface to lighten the spots on the arm area.
It is recommended that patients go to the dermatology department of regular hospitals, choose the appropriate treatment under the guidance of doctors, and do not blindly self-medication.
