Photothermic and photochemical action will be triggered by the radiation of IPL. On one hand, IPL will promote collagen reproducing and recombining which makes the skin more flexible and smooth. On the other hand, the light with long wavelength can easily pass through epidermis layer and will be absorbed selectively in priority by pathological pigments which will be destroyed by high heat, and get the effect of remove pigmentations, vascular lesions and unwanted hair.

当强脉冲光照射皮肤时，会产生生物刺激作用和光热解作用，一方面使皮肤中的胶原纤维和弹力纤维再生并重新排列，恢复皮肤弹性，从而减轻皱纹；另一方面，强脉冲光能穿透皮肤，被组织中的病变色素团优先选择性吸收，热能在不破坏正常皮肤组织的前提下，击碎病变色素团，从而达到治疗毛细血管扩张，祛除色斑，和脱除多余毛发的效果。
