Laser and light treatments often fade or clear age spots, but how well they work depends on the device, your skin tone, and whether the spot is actually a harmless sun mark. A 2022 systematic review found complete clearance in some cases, with pigment reduction ranging widely by technology. A medical exam before treatment matters as much as the laser itself.
TL;DR:
- Shorter wavelengths target superficial pigment with less risk, but deeper wavelengths can reach and affect tissues at higher danger.
- Q-switched lasers treat superficial spots in one to three sessions with minimal downtime, whereas ablative lasers clear deeper pigment faster but involve longer healing.
- Darker skin tones increase the risk of postinflammatory hyperpigmentation, requiring cautious device selection and patch testing before treatment.
- Operator training impacts safety significantly, with nonphysician operators responsible for most injury claims and the importance of choosing certified providers.
- Sun protection and avoiding recent tanning are essential pre- and post-treatment to prevent new pigmentation and maximize results.

How laser and light therapies work on pigmented spots
Lasers and intense pulsed light target melanin, the pigment that makes age spots visible. The light energy heats and fragments that pigment, and the body clears the debris over the following weeks. This process, known as selective photothermolysis, works best on solar lentigines, the flat brown marks that show up on sun-exposed skin like the face, hands, and chest.
Not every dark spot responds the same way, and some need a biopsy instead of a laser. Wavelength and pulse duration determine how deep the light travels and how much risk comes with it:
- Shorter wavelengths target superficial pigment with less risk to surrounding tissue.
- Longer wavelengths reach deeper layers but carry a higher chance of affecting nearby skin.
- Shorter pulse durations shatter pigment quickly, which suits small, concentrated spots.
Comparing device types: IPL, Q-switched, and fractional lasers
Clinics use several categories of devices for age spots, and each comes with its own trade-offs in speed, downtime, and risk.
- Q-switched lasers (including Nd:YAG and alexandrite) deliver short, high-energy pulses well suited to superficial pigmented lesions, typically requiring one to three sessions with minimal downtime.
- Intense pulsed light (IPL) treats broader areas at once and performs comparably to many laser devices for pigmentation, often with fewer severe side effects, though it may take more sessions to reach the same result.
- Non-ablative fractional lasers create controlled microscopic injury without removing the surface layer, balancing moderate downtime against steady improvement over several treatments.
- Ablative fractional lasers, such as fractional CO2, remove tissue directly and can clear deeper pigment and texture issues faster, but they involve longer healing time and a higher risk of pigment changes than non-ablative options.
Faster clearance generally trades off against a higher chance of complications, so the right choice depends on the depth of the pigment and your skin’s healing pattern, not just how quickly you want to see results.
Who is a good candidate, and how your skin tone changes
A benign solar lentigo is usually flat, evenly colored, and stable in size over time. A spot with an irregular border, mixed coloring, or a rough, scaly texture needs medical attention before any cosmetic treatment, since it could point toward an actinic keratosis or another lesion that requires biopsy rather than a laser.
Skin tone changes the calculation, too. Darker skin carries a higher risk of postinflammatory hyperpigmentation after laser treatment, so clinicians often adjust their approach:
- Choosing longer wavelengths and lower energy settings to reduce heat-related pigment changes.
- Running a patch test 48 to 72 hours before treatment on a small area of similar-toned skin.
- Using topical regimens before and after treatment to calm the skin and support even healing.
Treatment should also wait if you have had recent sun exposure or tanning, are pregnant, or take medications that increase photosensitivity.
Pro Tip: Bring a list of your current skin care products and medications to your consultation. Something as simple as a recent retinoid or an antibiotic can change which laser settings are safe.
What to expect from consultation through visible results
A laser consultation starts with a close look at the lesion, a review of your medical history, and photographs to track progress. This step also serves as informed consent, since your provider should walk through what the device does, what results are realistic, and what could go wrong.
From there, most people need somewhere between one and six sessions, spaced two to eight weeks apart depending on the device and how your skin responds between treatments. A few points to keep in mind before your first appointment:
- Avoid sun exposure and tanning beds for several weeks beforehand, since tanned skin absorbs laser energy differently.
- Stop retinoids, exfoliating acids, or other irritating products on the schedule your provider recommends.
- Expect some redness or darkening of the treated spot immediately after, which typically fades over one to two weeks.
Visible lightening usually appears within a few weeks of a session, with full results building over the full course of treatment rather than after a single visit.
Risks, side effects, and how to vet a provider
Redness, swelling, and temporary darkening of the treated spot are common after laser sessions and usually resolve within days. Less common but more serious risks include burns, scarring, and permanent changes in pigment, either lighter or darker than the surrounding skin.
Who operates the device matters as much as which device is used. A review of 69 laser-related liability claims between 2012 and 2020 found burns and scarring were common injuries, and 71% of the claims involved nonphysician operators performing delegated procedures.
71% of reviewed laser liability claims from 2012 to 2020 involved nonphysician operators, according to that same review, underscoring how much operator training affects safety outcomes.
Before booking, check for:
- Board certification of the supervising physician.
- Confirmation of who actually operates the laser and whether a physician is on-site during treatment.
- A patch test policy for anyone with darker skin.
- Before-and-after photos of patients with a skin tone similar to yours.
The American Academy of Dermatology recommends seeing a board-certified dermatologist specifically to reduce these risks.
Aftercare, maintenance, and what “permanent” really means
Sun protection after treatment is not optional. Unprotected treated skin can develop new pigment or lose the improvement gained during treatment, and it can also increase the chance of complications while the skin heals.
- Apply a broad-spectrum sunscreen daily, reapplying if you spend extended time outdoors.
- Use topical retinoids or brightening agents only as directed by your provider, since combining them too soon after treatment can irritate healing skin.
- Schedule periodic touch-ups if new sun exposure or aging brings new spots, since clearing existing pigment doesn’t prevent future sun damage from creating more.
Even effective treatments don’t make you immune to new age spots, and consistent sun protection habits do more for long-term results than any single laser session.
Pro Tip: Keep a small tube of sunscreen at your desk or in your bag. Reapplication, not just the first coat in the morning, is what actually protects treated skin.
A diagnosis-first approach to laser care
The biggest mistake in age spot treatment isn’t picking the wrong laser. It’s skipping the exam that tells you whether a laser is even the right tool. Age spots can look nearly identical to early actinic keratoses or other lesions that need biopsy, not light therapy, and treating them cosmetically first can delay a diagnosis that matters more than smoother skin.
At a reputable dermatology practice, that exam comes first. The approach pairs a physician-led evaluation with device selection matched to lesion depth and skin type, including patch testing for patients with darker skin tones before any laser touches the skin. A spot worth treating is a spot worth diagnosing correctly.

FAQ
Does laser treatment work on age spots?
Yes, lasers and light-based treatments commonly reduce or clear age spots, particularly solar lentigines. A 2022 systematic review found complete clearance in some cases, with pigment reduction ranging between approximately 67.9% and 94.4% depending on the device used.
What are two drawbacks of laser therapy?
Laser therapy can cause temporary side effects like redness and swelling, and less commonly, more serious ones such as burns, scarring, or permanent pigment changes. It can also require multiple sessions spaced weeks apart, which means a longer timeline and cost than a single visit.
How much does it cost to get age spots lasered off?
Cost varies by device, treatment area, and number of sessions, and insurance typically treats age spot removal as cosmetic, meaning it’s usually an out-of-pocket expense. A dermatology consultation is the most reliable way to get a specific estimate for your case.
What permanently removes age spots?
No single treatment guarantees a spot never returns, since new sun exposure and aging can create new pigment over time. Laser and light treatments can clear existing spots effectively, but lasting results depend on consistent sun protection and, in some cases, periodic touch-up sessions.
