How to remove dermal spots
In general, the removal of dermal pigmentation requires specific analysis based on different types of pigmented lesions. Common dermal pigmentation includes melasma, freckles, age spots (solar lentigines), café-au-lait macules, and nevus of Ota. Improvement can generally be achieved through methods such as applying sunscreen, carrying sun umbrellas, hyaluronic acid injections, chemical peels with fruit acids, intense pulsed light (IPL) therapy, picosecond lasers, and fractional lasers. It is recommended to visit a reputable medical facility and proceed under the guidance of a qualified physician.
