Arm freckles, which may be related to genetic factors and sunlight exposure, can be removed through medication and physical therapy.
1. Medication: retinoic acid, 3% hydroquinone cream and other medications can be used to promote pigment metabolism and remove pigment to remove freckles.
2. Physical treatment: for example, liquid nitrogen freezing treatment can corrode and peel off freckles through rapid low-temperature corrosion; however, at present, the most commonly used clinical treatment is laser treatment, such as photorejuvenation and picoseconds, which is able to remove freckles very well, and the treatment process is less painful and quick recovery.
During the treatment period, it is necessary to follow the doctor’s instruction to strictly protect the sun, so as not to leave pigmentation.
