Freckles are a very common skin disorder that manifests as scattered or dense, pinhead to rice-sized brown spots of varying shades on the face. The occurrence of freckles is mainly related to ultraviolet rays, which are usually obvious in summer and improve in winter, and have a hereditary tendency to occur continuously in the same area in several generations. Freckles affect the appearance of people, and patients urgently demand treatment. At present, the treatment of freckles adopts a variety of means to achieve satisfactory results and reduce recurrence. The all-round treatment of freckles includes: intense pulse laser treatment (photorejuvenation) + Q-switched 1064/532nm laser treatment + post-treatment care. Photorejuvenation technology uses the selective pyrolysis and photochemistry of Intense Pulsed Light (IPL) to micronize pigment particles in the skin without damaging the epidermis so that they can be engulfed by phagocytes and transported away through blood circulation. Photorejuvenation makes the skin smoother and improves skin dullness. For some deep freckles, the Q-switched 1064/532nm laser can be used to treat those who cannot achieve good results with strong pulsed light laser. After laser treatment of freckles, no scar will be left, and the treated area should be kept clean and protected by antibiotic ointment, in principle, it is not suitable to scrub with water. The occurrence of freckles is closely related to sunlight, if you often expose to sunlight recklessly after treatment, freckles may still come back. After the laser treatment of freckles, using special sunscreen and taking vitamin C orally can prevent the recurrence.
