Freckle is a pigmented and capacitive skin disease, which is related to genetic factors and sun exposure. The treatment of freckles includes topical medicine and laser treatment. Topical drugs mainly include hydroquinone cream, azelaic acid and other treatments, as well as chemical peeling treatment of fruit acid and compound acid. For laser treatment of freckles, including intense pulsed light therapy, Q-switched laser, picosecond and other treatments, laser treatment of freckles is better. However, it must be noted that after laser freckle removal, we must pay attention to the sunscreen and moisturizing of the skin to avoid the recurrence of freckles.
