脈衝光全名是「強力脈衝光」（IPL；Intense Pulse Light），屬連續光波（波長在560~1200nm），不像雷射是固定波長（不同雷射的波長不同）。因為脈衝光具有不同波長及高能量脈衝式瞬間強光，比雷射溫和，卻涵蓋所有常用雷射的波長，可同時解決色素斑、膚色暗沉、微血管擴張的泛紅、毛孔粗大、細紋等多種皮膚老化問題而進行全面性改善；脈衝光是「光回春術」代表。再者，脈衝光沒有恢復期，但雷射有恢復期。
The full name of IPL is Intense Pulse Light. It’s a continuous light (wavelength of about 560-1200nm). It differs to lasers as lasers have a fixed wavelength (different lasers have a different wavelength). Because pulsed light has different wavelengths, it also has different energy levels. Thus, it is more gentle than laser, but covers all the commonly used laser wavelengths. IPL simultaneously solves pigment spots, dull complexion, dilated blood capillaries, redness, large pores, aging skin, fine lines, and also carries out other improvements.
Furthermore, IPL requires no recovery time whilst laser does.
