How does Fractional Laser treatment work?
Fractional laser treatment is a non-invasive medication that uses a device to deliver a laser beam divided into thousands of microscopic medication zones that objective a fraction of the skin at a time. This is analogous to a photographic image being enhanced or altered pixel by pixel.
Fractional laser treatment has bridged the gap between the ablative and non-ablative laser techniques used to treat sun-damaged and aging skin. Whilst ablative laser medication work mainly on the epidermis (surface skin cells) and non-ablative medication work solely on dermal collagen (mid-layer of skin) only, fractional laser treatment works at both the epidermal and dermal layers of the skin.
The first fractional laser marketed was the Fraxel device Reliant Technologies now Solta], which emits a non-ablative 1550-nm wavelength. There are now a number of machines available that use fractional technology, based on erbium:YAG lasers for superficial medication and CO2 lasers for deeper ablative treatments (eg Fraxel Repair [Solta Medical], Active and Deep FX [Lumenis], Quadralase [Candela] and Pearl Fractional
