Laser Skin Tightening

Wrinkle removal by Laser especially, the non-ablative fractional laser, such as Fraxel, offers a great non-aggressive treatment to improve skin texture and quality and erase wrinkles via skin surfacing. This type can be combined with other lasers such as the Q-switch nanosecond laser to treat pigmentation and vascularity.

 

Fractional Laser

The fractional non-ablative Laser rejuvenates the skin by including college synthesis and remodeling without damaging the epidermis. The downtime of such procedure is significantly shorter than ablative Laser such as CO2. The Fraxel Dual, equipped with Thallium glass fiber and fractional hand, is the gold standard in skin tightening and wrinkle removal treatment. One of the main characteristics of photoaged skin is wrinkles. after chronic exposure to the sun, skin structure changes over time, histologically. Some of the features are Thin cellular epidermis, loss of skin elastic recoil due to the reduced dermal extracellular matrix, a significant decrease in the structural protein such as elastin and collagen. The non-ablative laser stimulates the skin’s resurfacing and collagen production without damaging the stratum corneum.

 

How does it stimulate the skin?

The fractional laser stimulates the skin by creating microthermal treatment zones (MTZs) to the reticular dermis as deep as 2 cm. These MTZs are in the shape of columns and serve as coagulation points. The untreated tissue areas between the MTZs supply the regenerative cells, the cornerstone of collagen remodeling and skin resurfacing.

fractional laser

Chromophores vary according to the type of Laser used. Some wavelengths are best absorbed by water, while others are absorbed by melanin and oxyhemoglobin chromophores. The objective is the same for all laser wavelengths, heating the skin to different degrees, creating coagulation points, and producing micro wondering investments to stimulate the fibroblast and collagen remodeling.

 

Fraxel Dual

Fraxel dual offers two different wavelengths, 1550 and 1927. The depth of penetration of these lasers is also based on their affinity for water, where shorter wavelengths such as 1550 nm have lower water absorption and deeper cutaneous penetration, which is associated with more significant dermal effects such as collagen remodeling and reduction of dermal dyschromia such as melasma. Longer wavelengths such as 1927 nm have higher water absorption with more superficial penetration and are used to treat epidermal pigmented lesions such as lentigines and ephelides.

Fraxel can be used with all kinds of wrinkle removal treatment with all skin types, with extra care applied to darker skin due to the higher risk of having PIH.
