The effectiveness of laser treatment for scars is definite, but several treatments are usually required to achieve satisfactory results. Do you have scars that significantly affect your function? Do you have conditions such as fingers that cannot be straightened or eyes that cannot be opened? After surgery has been performed to resolve the functional impairment, laser treatment can be used to further improve the appearance. Are your scars red, hard, itchy and painful? Is it still growing slowly? If your scars are in a significant growth phase, then a combination of radiation therapy and local injections are usually needed, not just laser treatment. After the growth of scars is controlled, laser treatment can be performed. For the timing of scar treatment, the current trend is early laser intervention. Laser treatment of scars gives improvements in three main areas: 1. Improvement of pigmentation abnormalities of scars. Scars with hyperpigmentation, which are darker than normal, can be made lighter and lighter by laser treatment; scars with hypopigmentation, which are lighter than normal, can be gradually darkened by laser treatment by stimulating pigment cells. However, generally hypopigmentation is more difficult to treat than hyperpigmentation, that is to say, it is more difficult to make light colors darker and relatively easy to make dark colors lighter. 2.Improve the flatness of scars. Scars commonly have an uneven appearance, and the use of appropriate equipment can gradually improve the depressed scars and make the prominent thickened scars shrink and flatten. 3.Improve the texture of scars. Most scars are poorly elastic, stiff and thickened or have a weak texture. Laser treatment can gradually restore the elasticity of scars and make them soft and resilient. Overall, for scars that are not obviously hyperplastic, have no obvious dysfunction or are no longer undergoing surgical treatment, laser can help you improve the appearance of scars that appear obvious and gradually become less obvious.
