How Does CO2RE Work?

The CO2RE fractional laser removes layers of skin in a fractionated method (columns of skin are removed, leaving the skin surrounding each column intact to aid in healing), resulting in new healthy and youthful skin.

This CO2RE laser technology is so precise that treatments can be tailored according to the nature and extent of the skin damage, skin type and individual requirements for recovery time. The CO2RE laser provides four variations of fractional resurfacing treatments – light, mid, deep and fusion. Because each treatment level is targeting specific skin problems (adjusted to treat both superficial and deep skin layers simultaneously), multiple settings can be used in one facial treatment, allowing for complete customization and optimal results.


Depth:  20 – 40 microns.

A complexion refresher that improves sun damage, uneven skin texture, enlarged pores and fine lines.


Depth:  100 – 200 microns.

Improves skin tone, texture as well as sun damage.


Depth:  500 – 800 microns (most effective treatment level).

Improves appearance of scarring, moderate to deep lines and wrinkles and skin laxity.


Depth:  Combines CO2RE Mid and Deep.

Improves skin tone, texture, scarring, lines and wrinkles – all in a single treatment pass.

How Many CO2RE Treatments Will I Need?

Generally, you will achieve significant improvement after one treatment.  Following laser treatment, your skin will gradually look softer and smoother.  Age spots and uneven skin texture will start to show gradual improvement. 

How Long Will the Results Last?

There are a number of variables that will determine how long you can expect the results to last, including your health, age and how well you maintain your skin post laser.  Dr McKerrow and his staff will be happy to provide you with useful skin care tips to make your results last as long as possible. 

What are the Side-Effects?

Redness:  Redness occurs as a natural response to the treatment and is to be expected.  It reflects collagen re-modelling as the skin heals.


Scarring:  Scarring may occur with any technology in which heat is produced such as lasers but it is rare overall.

Infection:  Infection is also rare.  The most common infection is actually a viral infection where a virus lays dormant in almost everybody and a herpetic outbreak can occur with the stress of laser resurfacing.  For this reason, all patients undergoing laser resurfacing will be given antiviral medication prior to commencement of treatment.

Post-inflammatory Hyperpigmentation:  Post-inflammatory hyperpigmentation is a condition in which the melanocytes in the dermis disperse melanin pigment in response to inflammation.  This occurs more commonly in darker skin types and is most common in Asian and/or Pacific Rim nationalities.  The condition is usually self-limiting and fades over time and can be treated with topical medications to hasten recovery.

How do I Prepare for Fractionated Resurfacing?

  1. Avoid sun exposure two weeks before treatment, and after treatment for as long as the area remains red or pink.
  2. Remove make-up and/or jewellery.
  3. Remove contact lenses if the area around the eyes is to be treated.
  4. Wear clothing that buttons down the front (no pullovers).
  5. Have someone come with you who can drive you home if the area around your eyes is to be treated.

Is the CO2RE treatment Painful?

The CO2RE treatment can be painful.  This will depend on the depth of treatment for the condition being treated.  At the Skin Specialist Centre, topical anaesthetic cream is supplied in conjunction with nerve blocks and oral pain relief to minimise pain during the procedure, and even the hours following it.

What Can I Expect Following Treatment?

Depending on the area and aggressiveness of the treatment, it will take 7 – 14 days for the skin to heal.  This downtime will include significant redness and crusting (possibly minor bleeding and oozing depending on treatment depth), dryness, peeling and flaking.  It is important to keep the skin moist following treatment. 

 After the first day your skin will be raw.   We usually review you in the clinic on the first and seventh day after the procedure to ensure that healing is proceeding according to plan.  By one week you can usually apply make-up and go out in public but your skin will still be pink and very sensitive for up to one month.  In order to minimize the risk of complications, it is important to follow all post-operative wound care instructions completely.  A strict skin care regime and sun avoidance is recommended for optimal healing;  failure to do so may result in sub-optimal results or side-effects. 

 To maintain the results we will achieve for you, we recommend a healthy skin care programme  including cosmetic products and possibly other procedures.
