Fractional Laser Treatment Bloomfield

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.

What is it used to treat?

Fractional laser treatment is used for the treatment of facial lines and wrinkles (rhytides) and skin pigmentation associated with photoaging, surgical and acne scarring, and chloasma.

Fractional laser treatment can be used on any part of the body, but is particularly useful on the neck, chest and hands when compared to traditional ablative modalities.

Fractional laser treatment may also be of benefit for poikiloderma of Civatte and stretch marks.

How does it 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-lay) 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.

Fractional laser treatment works by targeting both the epidermis and dermis. It does this by delivering a laser beam that is divided into thousands of tiny but deep columns of treatment into the skin. These are called microthermal treatment zones (MTZs). Within each MTZ old epidermal pigmented cells are expelled and penetration of collagen in the dermis causes a reaction that leads to collagen remodelling and new collagen formation. By using MTZs, the laser targets and treats intensively within the zone whilst surrounding healthy tissue remain intact and unaffected. This fractional treatment results in a faster healing process than if all tissue in the treatment area was exposed to the laser.
