Freckles are autosomal dominant and their development is related to sun exposure, so pigmentation spots are limited to exposed areas. Freckles are most common on the face (especially on the nose), shoulders and upper back. Its symptoms change with the seasons. In summer, the number of spots increases, the color deepens and the damage becomes bigger; while in winter, on the contrary, the number decreases, the color becomes lighter and the damage shrinks. 1.How can I get rid of my freckles? The traditional methods to remove freckles are whitening, chemical peeling and sunscreen. However, the efficacy is poor and easy to recur. With the introduction of intense pulsed light, the treatment of freckles has only undergone an epoch-making transformation. Most patients can say goodbye to freckles after only 2-5 treatments with an interval of 3 weeks. The treatment principle of intense pulsed light is “selective photothermolysis”. The energy of the photon is only selectively absorbed by the pigment vesicles in the freckles, which are broken up in an instant by the blasting effect. The broken melanin dust either falls off with the skin flakes or is phagocytosed by macrophages and discharged from the body with lymphatic circulation. Since photons are only absorbed by pigment groups, the surrounding normal skin will not be damaged, so the effect of spot removal is very safe. The treatment process takes only 15 minutes, and you can wash your face, put on makeup and do sports immediately after the procedure. 2.What are the side effects of OPT Intense Light Treatment for freckles? The early intense pulsed light technology (compound color light, light quantum) often makes the skin thin, sensitive and afraid of sunlight. The reason for this is that the waveform of the early photons is “spike-like” and the energy spikes are easy to cause damage. The fourth generation of OPT Intense Light (King’s Style) is equipped with nine powerful capacitors, emitting a “Great Wall battlements-like” square wave, completely free from the drawbacks of traditional photorejuvenation. After the treatment, there will be no burns, pigment changes, skin thinning, skin allergies, and no need to rest. You can wash your face, take a shower and go to work as usual after the treatment. The skin will also not be more afraid of the sun than before after the intense pulsed light treatment. However, you must develop a good habit of sun protection to avoid new freckles from growing out again. 3.How is the treatment efficiency of OPT Intense Light? After 2-4 treatments, the clearance rate of all patients’ skin lesions can reach 75%-100%. 4.Can freckles be cured? The lesions that have already appeared can be completely cured. Freckles are the result of the combined effect of heredity and sunlight, and no treatment can change the hereditary gene, but as long as sufficient sunlight protection can be achieved, the new occurrence of freckles can be prevented.
