The degree of fading of laser scars is related to the severity of the scars and there is individual variability. In general, those with lighter shades and thinner scars have the potential to fade completely to normal skin tone, while those with darker shades and thicker and harder scar tissue are able to reduce the shade to a certain extent, but usually cannot bring them back to full skin tone. The exact recovery may vary depending on the body type of each individual. Laser scar removal is a physical treatment, including pulsed dye laser, carbon dioxide laser and many other types. Laser heat can produce a series of effects on the epidermis and dermis, inhibit scar vascular density, and promote collagen proliferation and improve alignment, etc., so as to achieve the effect of fading scars. Laser scar removal can be used for people with proliferative, depressed, and atrophic scar conditions caused by burns, cuts, and facial acne remnants, etc. It may not always get rid of the scars completely, but it helps to lighten and soften them. For severe scars, such as scars that may have limited improvement, surgical scar removal, such as skin soft tissue expansion, can be chosen to have some effect on scar repair and improvement. It should be noted that both laser and surgical scar removal processes may have adverse reactions, such as burning the skin, scar fading effect is not obvious, etc. Sometimes multiple treatments are needed to achieve the desired effect, and the area should be kept clean and dry after laser treatment. In addition, patients with scars can consume more protein-rich foods such as eggs and lean meat, as well as fresh vegetables and fruits rich in vitamins in their daily diet. Avoiding spicy and stimulating foods during treatment, quitting smoking and alcohol, and paying attention to sun protection will help promote scar fading.
