Nowadays, laser beauty is not a new word, almost in the publicity of large and small beauty salons will be mentioned, laser skin rejuvenation, laser spot removal, laser eye bags, etc., as if the laser is a magical tool that can do everything. With the continuous exploration and development of its application areas by researchers, laser scar removal and acne scar removal are now possible.
Well, don’t rush to clean up those unsightly scars, before that, we need to briefly understand how the scar is formed. The skin can be roughly divided into two layers, a superficial layer called the epidermis and a deeper layer called the dermis. When the skin is damaged, the body initiates a series of repair processes. If the damage only reaches the epidermis, the repair will basically return to the original form. Once the dermis is damaged, the repair will result in scarring, which is the overgrowth of irregularly arranged collagen fibers. Due to the reduced collagen content and abnormal arrangement in the skin, the elasticity of the skin is diminished.
After understanding the formation of keloid scars, the next step is to understand how lasers are used to treat keloid scars. Lasers applied to scar treatment can be effective in improving all types of scarring. For atrophic scars, the laser can converge on the dermis through the epidermis to produce photothermal effects that stimulate local collagen growth and active growth factors, causing the depressed skin to augment in line with normal skin and be elastic. For hyperplastic scars, the laser can carbonize the tissue and destroy the proliferating collagen, resulting in tissue grinding.
Well, now let’s go and start the beautiful laser scar removal journey.
