Brief Summary

1. Fractional laser has become an important laser modality in management of a number of skin conditions and photoaging. Fractional photothermolysis is the fractional emission of light into microscopic treatment zones, creating small columns of injury to the skin in a pixilated fashion. Epidermal and dermal disruptions occur in these focal zones of thermal injury, stimulating dermal collagen production and elastic tissue formation. Fractional laser has been used successfully to treat photodamage and overall dyschromia in the Caucasian population. However, there is not much improvement in Asian population.

2. Photoaging refers to the skin caused by intense and chronic exposure to sunlight. The visible effects of photoaging are fine wrinkles, mottling, pigmentation and roughness of the skin. These changes are usually associated with chronologic aging. However, photoaging is not a good indicator of chronologic age. It just makes a person look older than his or her chronologic age. Skin ageing may be divided into two processes: intrinsic ageing and extrinsic ageing (or photoageing). Both are accompanied by changes in the morphological and biomechanical properties of skin.

3. Profile HaloTM dual-wavelength fusion fractional laser is the first hand tool in the world that integrates ablative and non-ablative fractional lasers. It includes a non-ablative fractional laser with a wavelength of 1470nm and an ablative fractional laser with a wavelength of 2940nm. A day after treatment, new epithelial tissue began to appear, and the necrotic epidermis formed microepidermal necrotic debris (MENDs). MENDs were surrounded by keratin 2-7 days after treatment, and collagen sequence in MTZs was changed 7 days later. The 2940 ablative fractional laser can be added with 20-100 micron lattice stripping, ensuring safety while enabling MENDs to be peeled off 2 days earlier and reducing the risk of side effects. This makes the laser safe and effective compared with the single fractional laser and reduces the downtime.
