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, 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 ageing skin. While 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 fractional laser treatment used to treat?

Fractional laser treatment is used for the treatment of:

  • Facial lines and wrinkles  (rhytides)
  • Sun damage
  • Skin pigmentation associated with photoaging
  •  Acne scar

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 stretch marks.

Fractional laser treatment can be used in all skin types and patients, but techniques vary depending on patient age, skin type, sun exposure and body location. Fractional laser treatment can be combined with surgery and other skin treatments

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.

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 the 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 while surrounding healthy tissue remain intact and unaffected and helps heal the wound. This fractional treatment results in a faster healing process than if all tissue in the treatment area was exposed to the laser.

Pre-treatment assessment/preparation

  • Define problem areas and tailor a treatment pattern to target the areas for correction.
  • Take pre-treatment photographs.
  • Pre-treatment with bleaching cream   may be necessary for patients with darker skin or pigmentation problems.
  • Consider medications  prophylaxis against herpes simplex virus.
  • The patient needs to remove all jewellery and makeup. Wash face with soap and water before treatment.
  • An anaesthetic cream is applied to the treatment area. It takes about 45-60 minutes for the anaesthetic to take full effect.

Post-treatment and recovery

  • Patients may experience a mild sunburn sensation for about an hour after the procedure.
  • Swelling is usually minimal and should resolve in 2–3 days.
  • The skin will have a pinkish tone for 3–5 days.
  • Within 24 hours new epidermal skin develops and the skin will have a bronze appearance that can last 3–14 days. Flaking of the skin may also occur as new skin replaces dead skin tissue, which can be treated with a moisturising cream.
  • Skin peeling can be pronounced after ablative therapy when the skin should be gently removed with tap water, petrolatum and gauze once or twice daily.
  • During the healing phase and for several months after treatment, it is recommended that the treatment area is protected using a moisturising sunscreen with an SPF of at least 50+. Protective clothing and wide-brimmed hats should also be used to protect the skin from sun exposure.

Four to five treatments with Fraxel® are required, depending on the energy level used and the condition of the treated skin. These are spaced one month apart. The results are not immediate and are slowly progressive, with optimal improvement visible over a three to four month period. This timeframe and treatment regimen allows for complete healing and replacement of damaged tissue with new collagen and elastin, and viable, healthy skin cell growth.

Ablative fractional resurfacing lasers are more aggressive than non-ablative devices, so recovery takes a little longer.

What are the side effects and complications of fractional laser treatment?

Fractional laser treatment appears to be well tolerated by most patients. Shaving or application of mineral make-up can be done soon after treatment. In most cases, patients can return to work directly after treatments or the following day, depending upon their skin condition and treatment.
