Scar Revision

Improving the Appearance and Texture of Scars

Scars are a normal part of the body’s healing process, but the final appearance can vary considerably. Some scars remain raised, firm or uneven, while others become indented, discoloured or noticeably different in texture from the surrounding skin. Fractional CO₂ Laser can be used for selected scars with the aim of improving texture, flexibility and overall appearance through controlled resurfacing and collagen remodelling.

At YT Medical, scar treatment begins with assessment rather than automatically applying laser to every visible scar. We consider how the scar developed, how long it has been present, whether it is raised or depressed, its colour and texture, previous treatment, surrounding skin and whether there are any ongoing symptoms. These factors help determine whether CO₂ treatment is appropriate or whether another scar-management approach should be considered.

Which Scars Can Be Treated?

Fractional CO₂ Laser may be considered for selected surgical scars, traumatic scars and other established textural scars. The treatment creates microscopic columns of controlled thermal injury within the scar and surrounding tissue, initiating a healing response that can encourage remodelling of abnormal or irregular collagen.

Scars differ considerably, however, and not every scar should be treated in the same way. Raised hypertrophic scars, keloid-prone scars, indented scars and scars with significant pigmentation may require different treatment strategies. If a scar is painful, persistently inflamed, changing unexpectedly or otherwise clinically concerning, further medical assessment may be required before cosmetic treatment is considered.

What Does Treatment Involve?

The laser is passed across the selected scar using settings determined by the scar characteristics, treatment area and patient’s skin. Depending on treatment intensity, local anaesthetic or another comfort measure may be used. Redness, swelling, heat and tenderness are expected afterwards, followed by a healing period during which the treated skin can become dry, rough, crusted or flaky.

Sun protection and appropriate skincare are especially important throughout recovery. Patients should avoid picking healing skin or attempting to accelerate peeling, as unnecessary disruption can increase the risk of complications.

How Much Can a Scar Improve?

Scar revision is about improving a scar rather than erasing it completely. Fractional CO₂ Laser can produce meaningful changes in appropriately selected scars, but the degree of improvement varies according to scar type, age, depth, location and individual healing response.

More than one treatment may be recommended, particularly for established or more prominent scars. Collagen remodelling also continues after the visible surface has healed, meaning improvement should be assessed progressively rather than immediately following treatment.

Possible complications include prolonged redness, infection, changes in pigmentation, delayed healing and further scarring. Pigmentation risk is particularly relevant for some skin types and will form part of your consultation.

A Wider Scar-Remodelling Approach

CO₂ Laser is one of several options available within YT Medical’s Scar Remodelling pathway. Depending on the scar, Medical Microneedling, PRP, PRF or another treatment may sometimes be considered either instead of laser or as part of a carefully planned programme.

The objective is to select treatment according to the individual scar rather than using the same procedure for every patient.
