Fraction Laser

Fractional laser treatment is a non-invasive treatment that uses a device to deliver a laser beam divided into thousands of microscopic treatment zones that target 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 treatments work mainly on the epidermis (surface skin cells) and non-ablative treatments work solely on dermal collagen (mid-layer of skin) only, fractional laser treatment works at both the epidermal and dermal layers of the skin.

How does fractional laser treatment work?

To understand how fractional laser treatment works a basic understanding of skin structure is required. Briefly skin consists of 3 layers, the epidermis (uppermost layer), dermis (mid-layer) and subcutis (lower fat layer). The epidermis contains pigment-producing cells called melanocytes, which are responsible for skin colouring. The dermis is made up of collagen and elastin fibres that provide skin with strength, toughness, elasticity and pliability (click here for detailed information on skin structure).

As the body ages, the appearance and characteristics of the skin alter. The epidermis becomes thinner so blemishes become more visible, and collagen in the dermis is gradually lost which contributes to the formation of facial lines, sagging skin and wrinkles.
