Fractional Laser Introduction: Erbium fractional laser technology is a minimally invasive treatment between invasive and non-invasive that has gained global attention in the past two years and can effectively treat acne scars and other causes of scarring, laser resurfacing, wrinkle reduction, Civatte skin heterochromia, skin laxity and other photoaging problems. What is a fractional laser? Fractional laser is the output of a single wavelength of light in the form of micro-laser beams arranged in a matrix. These fine micro-laser beams selectively act on the target tissue to stimulate the production of new collagen in the dermis for the purpose of wrinkle reduction and skin rejuvenation. What is the principle of fractional laser wrinkle reduction? The energy of the fractional micro-laser beam is absorbed by the epidermis and dermis it passes through, resulting in columnar thermal denaturation or the formation of true apertures (columnar skin loss) in these areas, which can uniformly initiate the skin repair process, leading to remodeling and reconstruction of the entire skin layer, including the epidermis and dermis, for the purpose of wrinkle reduction. How long does the treatment effect of fractional laser last? The effect of fractional laser treatment depends on the nature of the patient’s lesions, recovery time, personal constitution, skin type and personal habits, so the final effect and the duration of maintenance vary from person to person. Can fractional laser treat scarring? Fractional laser has better treatment effect on depressed atrophic scars such as post-acne, chickenpox and other disease scars, post-surgical hyperplastic scars, etc. Keloid scars can be treated by photodynamic therapy or botulinum toxin injections. Who is suitable for fractional laser? Fractional laser treatment is suitable for a wide range of people, especially for those with forehead lines, crow’s feet, perioral wrinkles, skin laxity and other photoaging and post-acne scarring. Who is not suitable for fractional laser? Not all people with wrinkles or scars are suitable for fractional laser: e.g. people with a history of scar allergy, hypersensitive people and pregnant women. Fractional treatments must be carefully selected by the physician in order to achieve better results and avoid serious adverse events. Fractional laser treatment requires attention: 1. Depending on the purpose of treatment, the immediate reaction and the degree of treatment may vary, so you should communicate more with your physician within 3 days after treatment. 2. Avoid excessive makeup. 3, sun protection is very important (use physical sunscreen with SPF ≥ 30-50, apply 30 minutes before going out; both indoor and outdoor). 4, some patients will appear hyperpigmentation, usually in 3-6 months will be reduced. 5.Avoid forceful massage of the treated area and sweaty exercise.
