In short. What each of the three reaches, what a course involves, and the pigment risk that is higher in darker skin tones. Choosing by the change rather than by the device.
Key points
- Fractional resurfacing, whether ablative or non-ablative, is the only rung that reaches widespread textural change, because it works in the dermis as well as at the surface.
- It costs days to weeks of visible recovery, a redness that outlasts the healing, and a real risk of pigment change afterwards — higher in darker skin tones, and higher again when protection is not maintained.
Peels, light treatment and resurfacing are often discussed as one thing and are three: they reach different depths, address different changes, and cost different amounts of recovery. What decides between them is the change being treated rather than the device being offered.
Peels: the surface, in a course
A chemical peel removes a controlled layer of the surface and lets the skin renew. Depth is the variable that matters: a light peel refreshes the surface with little or no visible recovery, and a deeper one reaches further and costs several days of peeling and redness. Peels are used mainly for tone, pigment and surface texture, and are given as a course. Their effect is real and it fades, because the light that produced the pigment continues to arrive.
Light treatment: colour rather than texture
Intense pulsed light and pigment-specific lasers target pigment and, in some cases, the vessels that give a background redness. They are given over a series of sessions spaced weeks apart, work on colour, do very little for texture and nothing at all for laxity. A common disappointment is a person who expected light treatment to change the quality of their skin and found only the colour improved.
Resurfacing is a different proposition
Fractional resurfacing, whether ablative or non-ablative, is the only rung that reaches widespread textural change, because it works in the dermis as well as at the surface. It costs days to weeks of visible recovery, a redness that outlasts the healing, and a real risk of pigment change afterwards — higher in darker skin tones, and higher again when protection is not maintained.
The risk that is shared, and who carries it
Every one of these treatments can leave the treated skin darker or lighter than it was. The risk is highest in darker skin tones, after deeper treatments, after treatment in summer, and in anyone who has had the problem before. This is not a reason to refuse treatment to people with pigmented skin; it is a reason to plan it differently, to prepare the skin beforehand, and to treat the risk as part of the consent.
Choosing between them honestly
The question to ask is which change is being treated. Colour and uneven tone point to the topical and light rungs. Surface roughness and fine texture point to peels and to non-ablative resurfacing. Laxity is a loss of support rather than a surface problem, and a plan offering light treatment for a face whose main complaint is sagging has not matched the treatment to the problem.
Before agreeing to a course
- Ask what will be done about pigment risk afterwards, given your own skin tone.
- Ask what protection is required during the course, and whether the timing is right.
- Be cautious of a package sold before the change being treated has been named.
The limits of the rung below this one are covered in what topicals can and cannot change, and the maintenance these results depend on is described in living with sun damage.
Frequently asked questions
How many sessions does sun-damaged skin usually need?
It varies with the change being treated, the depth chosen and how the skin responds, and a course is usually described as a range rather than a fixed number. Sessions are spaced weeks apart so that the skin recovers between them, and the plan is reviewed as it goes. Anyone quoting an exact number before examining the skin is guessing.
Why is pigment risk higher in darker skin tones?
Because the cells that produce pigment are more active, and any injury to the skin stimulates them. The same treatment that lightens uneven colour in one person can leave a darker patch in another, which is why preparation, conservative settings, a small test area where appropriate, and protection afterwards matter more in these skin tones rather than less.
Does resurfacing remove sun damage permanently?
It improves texture and tone, and the improvement is real, and it does not return the skin to how it was before the exposure. The light that produced the problem continues to arrive, so the result is held by protection and by repeating treatment rather than completed once. Anyone presenting it as a one-off correction is describing something that does not exist.
Risks & Limitations
- Damage already in the dermis is improved by treatment rather than removed by it, and the improvement fades while the exposure that produced it continues.
- Peels, light treatment and resurfacing can leave the treated skin darker or lighter than it was, and the risk is higher in darker skin tones.
- Resurfacing costs days to weeks of visible recovery, and redness often outlasts the healing.
- Skin with a large cumulative dose stays at raised risk of further lesions after treatment, which is why review continues rather than ends.
When to Seek Care
- A mole or patch that changes in size, shape, colour or height.
- A spot that bleeds without being knocked, crusts, itches persistently or fails to heal over a few weeks.
- A new lump or nodule on skin that has had a great deal of sun, particularly on the face, ear, scalp or lip.
- Persistent redness, scaling or roughness across an area of skin rather than in a single spot.
