Treatment of Coffee Spots In the past, most of the treatments were done by freezing, CO2 laser, skin resurfacing, etc. However, they tend to leave scarring and permanent pigmentation, and the results are not good. With the introduction of the ruby laser, the treatment of coffee spots has shown excellent results. The wavelength of ruby laser is 694nm, which can be selectively absorbed by the pigment cells and pigment particles of the skin, causing them to be heat dissolved and broken, and gradually metabolized and absorbed by the body, without damaging the surrounding normal skin. The new Q-switch unique flat cap output technology, change the previous “point to point” mode, using “face to face” laser parallel emission mode, the spot energy density is uniform, the pigment particles to produce blasting effect, the skin damage is small, the skin is not easy to It is less likely to bleed. Ruby laser treatment for coffee spot patients Treatment times: At least 1~6 treatments are needed to avoid repigmentation of nearby unirradiated melanocytes. Age of treatment: Patients who develop the disease before the age of one and those who are actively treated before the age of five have good efficacy, but there are some patients who are more prone to recurrence the younger they are. Treatment interval: Generally, the interval is 2~3 months. If there is pigmentation after one treatment, you need to wait for the pigmentation to subside before the next treatment. Post-treatment care: Ice pack cold compress immediately after treatment. Avoid sun exposure between treatments and apply moisturizer and sunscreen externally. Efficacy: After several treatments, most patients can achieve satisfactory results with a low recurrence rate, but in a very small percentage of patients the results are sometimes unpredictable.
