Ms. Wu of Qingdao, Shandong Province: I grew up at the beach, which know what sunscreen is when I was a child! But now I’m 40 years old and a lot of deep and shallow spots have started to appear on my face. I heard a friend say that this is a sun spot, go to do photorejuvenation can be removed, is it really so effective? Huang Luping: Our skin will remember every sunburn, which will not only lead to skin aging and discoloration, but will also increase the risk of skin malignancy in the future. Women should pay extra attention to dull skin tone and sun spots from the age of 25 onwards. It is recommended that at this time, women can undergo photorejuvenation to remove sun spots. Photorejuvenation for sun spots works through the principle of selective absorption of light. Pigmented spots are heated by absorbing more light energy due to their darker color than skin tone, thus leading to the destruction of pigmented tissues and shedding them in the form of microscabs to achieve the effect of pigmentation removal. Due to the biological effect of light, it will stimulate the collagen in the dermis to proliferate and arrange regularly, thus photorejuvenation has the effect of brightening and whitening at the same time. The process of photorejuvenation for sun spots removal usually requires 3-5 sessions, with an interval of 3 weeks between each two treatments, and each treatment is a comprehensive treatment to achieve a uniform cosmetic effect.
