很多美容院都有IPL treatment，说是可以用来minimize or remove: age spots sun damage freckles birthmarks varicose veins broken blood vessels on your face rosacea hair on your face, neck, back, chest, legs, underarms, or bikini line 还有的说IPL treatment uses intense wavelengths of light to heat the surface enough to stimulate the skin to naturally regenerate while boosting collagen production 什么波长的IPL会对皮肤起到上述的作用呢？家用的脱毛机，比如飞利浦Lumea是用IPL脱毛，那对皮肤有没有其他正面的作用呢？
