There are two types of marks left by acne, one is a red mark and the other is a pigmented spot. Both types of marks can fade over time. If you feel that the fading time is too long or too slow, affecting your daily life and aesthetics, you may want to try phototherapy. Photons can be very good at making capillaries shrink and red acne marks are actually caused by dilated blood vessels, so they can be easily removed; photons can also make smash pigment spots and gradually absorb them. Photorejuvenation can play a more significant role in treating and promoting these two skin problems.
