Laser treatment helps sun damaged skin by targeting two different things: the brown marks left by years of UV exposure, and the general texture and redness changes that come with photoageing. Which one is being treated matters, because they respond to different settings and sometimes different devices.
What laser will not do is undo the damage itself. Sun exposure changes the deeper structure of skin permanently, and treatment improves how that skin looks rather than reversing what happened to it.
Important clinical note. Medical-grade laser skin rejuvenation is a higher risk non-surgical cosmetic procedure. All laser treatments carry risks, including temporary redness, swelling, blistering or changes in skin pigmentation. Outcomes depend on your skin type, your biology and the extent of existing sun damage, and results are not guaranteed.
A clinical consultation is required, and you are encouraged to seek a second opinion from an appropriately qualified health practitioner. This page is general information, not medical advice.
What sun damage actually looks like
Photoageing is the accumulated effect of UV exposure on skin structure, and it shows up as several separate signs rather than one. They do not all respond the same way, which is why an assessment matters more than picking a device.
| Sign | What it is | How it typically responds |
|---|---|---|
| Flat brown spots | Solar lentigines, the classic sun spot | Often responds well to pigment-targeting laser |
| Diffuse redness | Dilated surface vessels | Needs a vascular-targeting approach, not a pigment one |
| Rough or crusty patches | Solar keratoses | Medical, not cosmetic. Needs assessment before anything else |
| Fine lines and coarse texture | Collagen and elastin change in the dermis | Gradual improvement through collagen stimulation over a course |
| Enlarged pores and dullness | Surface texture change | Usually improves alongside the texture work |
The one to get checked first. Rough, scaly or crusty patches that do not settle can be solar keratoses, which are a medical finding rather than a cosmetic one. The Cancer Council Australia recommends that any new, changing, bleeding or non-healing spot be assessed by a doctor before cosmetic treatment is considered. Treating a lesion cosmetically can remove the visible sign of something that needed proper attention.
What laser can and cannot change
Being clear about the limits matters, because sun damage is often advertised as something that can be erased.
- Discrete brown spots can often be cleared or substantially faded
- Redness and visible vessels can be reduced with the right device
- Texture and fine lines improve gradually as collagen responds, across a course rather than a single session
- Deep wrinkles, significant laxity and structural change are not corrected by resurfacing alone
- New damage still accumulates afterwards, so results are maintained by sun protection or they are not maintained at all
How laser works on sun-damaged skin
Laser delivers focused light energy at a specific wavelength. Different wavelengths are absorbed by different targets in the skin, which is why no single laser does everything.
- Pigment-targeting wavelengths are absorbed by melanin. The energy breaks up clusters of pigment so the body can clear them through its normal processes over the following weeks.
- Vascular-targeting wavelengths are absorbed by haemoglobin in dilated blood vessels, reducing visible redness and broken capillaries.
- Resurfacing wavelengths create a controlled thermal effect in the dermis. The healing response prompts the body to produce new collagen and elastin, which can gradually improve texture, fine lines and pore size over months.
The depth, intensity and pattern of energy delivery all vary between devices and settings. That is why a clinical assessment determines the approach rather than a device name.
Types of laser approach for sun damage
Several broad categories exist, each with a different balance of intensity, recovery and what it can address.
- Ablative laser resurfacing removes the outer layer of damaged skin and heats the dermis beneath. CO2 laser treatment is the most established ablative option for significant sun damage and textural change. Recovery takes longer, but the degree of improvement in a single course can be greater.
- Non-ablative laser heats the dermis without removing the surface. Downtime is minimal or absent, making it suited to people who cannot take time off for recovery. Results build over a course of sessions.
- Fractional delivery treats microscopic columns of skin rather than the entire surface, leaving untreated tissue between them. This speeds healing compared with full-surface treatment and can be applied in both ablative and non-ablative modes.
- IPL (intense pulsed light) uses broad-spectrum light rather than a single wavelength. It can address both pigment and diffuse redness in the same session, making it a common starting point for general photoageing.
For pigmentation that sits deeper or responds poorly to laser alone, Cosmelan depigmentation treatment or professional chemical peels may be considered as alternatives or additions to a laser-based plan.
Where Laser Genesis fits
Laser Genesis works by gently heating the upper dermis to stimulate collagen, which is why it is generally used for overall tone, texture and diffuse redness rather than for removing individual spots. It involves no downtime, and results build over a course.
Where the concern is defined brown marks rather than overall tone, a pigment-targeting approach is the better fit. Those are covered on our solar lentigine treatment and pigmentation removal pages. Scaly patches that turn out to be solar keratoses are handled differently again.
Most people with genuinely sun damaged skin have more than one of these at once, so a plan often combines approaches rather than relying on a single treatment.
What recovery involves
Recovery depends on the type and intensity of treatment. General principles apply across most laser work for sun damage.
- Non-ablative treatments such as Laser Genesis typically involve little or no downtime. Mild redness that settles within hours is common.
- Ablative resurfacing involves a proper recovery period. The treated area may be red, swollen and may peel or crust over the first one to two weeks. The skin underneath is new and more sensitive than usual.
- Sun protection is not optional. Treated skin is significantly more sensitive to UV. Daily broad-spectrum sunscreen and physical protection (hat, shade, avoiding peak UV hours) are part of the treatment plan, not aftercare extras.
- Collagen takes time. Texture and firmness improvements develop over weeks to months as the body’s healing response progresses. What you see at one week is not the final result.
Your clinician will explain the specific recovery expectations for your plan, including what products to use and what to avoid during healing. Skin needling is sometimes used as a complementary treatment for collagen stimulation between laser sessions, depending on the plan.
Who is a good candidate
Most adults with visible sun damage can be considered for laser treatment, but several individual factors affect which approach is appropriate and how the skin is likely to respond.
- Skin type and tone. Lighter skin types tend to respond more predictably to certain wavelengths. Darker skin types carry a higher risk of post-inflammatory pigmentation and may need adjusted settings or a different device.
- The type and depth of damage. Surface-level spots, deeper collagen change and vascular redness each call for different approaches, and an assessment identifies which combination is present.
- Medical history. Certain medications, active skin conditions and immune factors can affect healing and are covered during consultation.
- Sun exposure habits. Ongoing unprotected sun exposure works against treatment outcomes. A plan includes how to protect treated skin going forward.
Anyone with a new, changing or irregular spot should have a skin check before cosmetic treatment is considered.
Why this comes up so often in Adelaide
South Australia carries high UV for much of the year, and the damage being treated now is usually the result of exposure decades ago. That lag is why sun damage tends to appear in your forties and fifties despite better sun habits in the years since. SunSmart notes that UV in southern Australia is strong enough to cause skin damage for much of the year, not only in summer.
Timing also matters for treatment. Laser work is generally better started in the cooler months, because treated skin is more sensitive to UV and fresh exposure during a course can trigger pigmentation rather than clear it.
Common questions
How many sessions does sun damage take?
The number depends on what is being treated. Discrete brown spots can respond in a small number of sessions, while tone and texture work builds across a course. You will be given a realistic expectation at consultation rather than a fixed number up front.
Is there downtime?
It varies by approach. Laser Genesis is generally a no-downtime treatment, while ablative resurfacing involves a recovery period of one to two weeks. Temporary redness is common after most laser work.
Will the sun damage come back?
Existing damage that has been treated can return with further UV exposure, and new damage continues to accumulate. Daily sun protection is what holds a result, which is why it is treated as part of the plan rather than optional aftercare.
Can laser treat a spot I am worried about?
Not before it has been assessed. Anything new, changing, irregular, bleeding or not healing needs a medical look first. Cosmetic treatment is only appropriate once a lesion is known to be harmless.
Is it safe on darker skin?
It can be, with adjusted settings and a more gradual course, because darker skin types carry a higher risk of post-inflammatory pigmentation. Tell us about any previous reaction to laser or light treatment at your consultation.
Treatment and aftercare
Which type of laser works best for sun spots?
Pigment-targeting lasers tend to be the most direct option for discrete sun spots (solar lentigines). IPL can also address them, particularly when there is broader discolouration alongside individual spots. The right choice depends on the depth of pigment, your skin type and what else is being treated at the same time.
Can chemical peels help with sun damage?
Professional chemical peels can improve surface-level pigmentation, texture and dullness caused by sun exposure. They are sometimes used alongside laser treatment as part of a broader plan, or as a standalone option for milder photoageing. Your clinician can advise whether a peel, laser or combination approach suits your skin.
What should I do after treatment to protect my skin?
Follow the specific aftercare instructions from your clinician. In general, daily broad-spectrum sunscreen (SPF 30 or higher), physical protection such as a hat, and avoiding extended midday sun are standard.
Gentle cleansing and keeping the skin hydrated help the healing process. Avoid exfoliating products or active ingredients until your clinician says the skin is ready.
Is laser treatment for sun damage uncomfortable?
Sensation varies by treatment type. Non-ablative treatments like Laser Genesis are generally well tolerated, often described as a warming feeling.
More intensive resurfacing may involve numbing cream or cooling to manage discomfort during the session. Your clinician will discuss what to expect before the treatment begins.
The short version
Laser helps sun damaged skin by clearing pigment, reducing redness and improving texture. The right approach depends on which of those is your main concern, how deep the damage sits and how much recovery time you can manage. Results improve how the skin looks rather than undoing the underlying damage, and sun protection is what keeps them.
