1.Why do you have freckles? Freckles are autosomal dominant, and their development is related to sun exposure, so the pigment spots are limited to the exposed areas. Freckles are most common on the face (especially on the nose), shoulders and upper back. The number of freckles increases in summer, the color deepens and the damage becomes bigger; on the contrary, the number decreases, the color becomes lighter and the damage shrinks in winter. 2.Can freckles be cured? The skin 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 genetic genes, but as long as we can achieve sufficient sun protection, we can prevent the new occurrence of freckles. 3.How can I get rid of freckles? The traditional methods of removing freckles are nothing but 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 seen an epoch-making transformation. Most patients can say goodbye to freckles after only 3-5 treatments with an interval of 4 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 exercise immediately after the procedure. In addition, lasers that can be selectively absorbed by melanin vesicles are able to remove freckles, such as Q-switched Nd:YAG (1064nm) Q-switched Purple Jade Gemstone laser (755nm) Q-switched KTP multiplier laser (532nm) For freckles on upper eyelids and lips, these selective lasers are preferred instead of intense pulsed light. 4.What are the side effects of intense light treatment for freckles? The new generation of intense light completely gets rid of the drawbacks of traditional photorejuvenation. After treatment, there will be no burns, pigment changes, skin thinning, skin allergy, and no need to rest. You can wash your face, 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 back.
