Laser Treatment for Sunspots: How PicoWay Removes Age Spots and Solar Lentigines

Last Updated: March 2026  ·  Reviewed by Jinli Wu, PA-C  ·  Skin Select, Brentwood Los Angeles

Quick Answer

PicoWay picosecond laser removes sunspots and age spots by targeting excess melanin with precision pulses that shatter pigment without damaging surrounding skin. Isolated sunspots typically clear in 1 to 2 sessions. The treated spot darkens for about a week, then flakes off as the pigment clears.

What Are Sunspots, and How Are They Different from Other Dark Spots?

Sunspots, technically called solar lentigines, are flat, uniformly pigmented marks caused by cumulative UV exposure. They're most common on the face, hands, chest, and shoulders. They tend to appear gradually, become more noticeable in your 40s and 50s, and then stay. Unlike freckles, which fade in winter, sunspots don't go away on their own.

The distinction matters for treatment. Post-inflammatory hyperpigmentation (from acne or injury) sits at varying depths and involves reactive melanocytes. Melasma is driven by hormonal fluctuations and has a different treatment protocol. Solar lentigines are localized deposits of excess melanin in the upper dermis, which is exactly where PicoWay's 532nm wavelength is most precise.

Solar lentigines are also among the most predictably treated pigmentation conditions. Because they're well-defined, superficially located, and not driven by ongoing hormonal activity, they respond consistently to laser treatment in fewer sessions than more diffuse types of pigmentation.

Why Creams and Serums Don't Remove Sunspots

Topical brightening ingredients, vitamin C, niacinamide, kojic acid, azelaic acid, work by interfering with the enzyme that produces melanin. They slow down production. What they can't do is break down melanin that's already there. For new or shallow post-inflammatory marks, consistent use over months can produce meaningful fading. For established solar lentigines, the realistic expectation is modest lightening at best.

Prescription hydroquinone is stronger and can fade superficial pigmentation over 12 to 16 weeks of consistent use. But it works slowly, requires breaks from use to prevent complications, and doesn't reliably clear deep-set spots. Patients who come in after years of topical treatment have usually already learned what topicals can and can't do.

Laser treatment addresses the pigment directly. PicoWay targets melanin at the cellular level, breaking it apart in a single session rather than asking the body to suppress it over months.

How PicoWay Age Spot Laser Treatment Works

PicoWay delivers laser energy in pulses measured in picoseconds, each one a trillionth of a second. At that speed, the energy creates a photoacoustic shockwave rather than a predominantly thermal effect. The rapid expansion and contraction within the target tissue shatters melanin granules into tiny particles. The body's lymphatic system then clears those fragments over the following weeks.

For sunspots, the 532nm wavelength is the primary tool. This wavelength is selectively absorbed by superficial melanin and hemoglobin. Because it targets the pigment without heating the surrounding dermis to the same degree as older lasers, the risk of collateral damage is lower and healing is faster.

After treatment, the spot turns darker for a few days as the fragmented melanin rises to the surface. A thin crust forms, then flakes away. By two weeks, the cleared area is usually noticeably lighter than the original spot. Final results settle over 4 to 6 weeks as the lymphatic system finishes the job.

PicoWay vs. IPL for Sunspot Removal: What's the Difference?

IPL (intense pulsed light) is the most common device used for sunspot treatment outside of medical practices, and it does work for some patients. The limitation is specificity. IPL uses a broad spectrum of wavelengths rather than a single targeted wavelength, which makes it less precise. On lighter skin with isolated sunspots, IPL can deliver acceptable results. On mixed pigmentation, darker skin tones, or areas with a lot of surface variation, IPL's imprecision becomes a problem.

Q-switched Nd:YAG lasers are another option still in wide use. They're effective, but they operate on pulse durations in the nanosecond range, which means more heat generated per pulse. More heat means more surrounding tissue affected, longer healing, and a higher risk of post-inflammatory pigmentation in darker skin types.

PicoWay's picosecond pulses deliver energy with less heat and more precision. For isolated sunspot removal, it typically achieves the same or better clearance in fewer sessions and with faster healing. Patients who've had IPL with partial results often see complete clearance in one or two PicoWay sessions.

Sunspot Laser Treatment Before and After: What the Healing Process Looks Like

The healing process after PicoWay sunspot treatment follows a predictable pattern. Immediately after the session, treated spots are red and may feel slightly warm. Over the next 24 to 48 hours, they darken noticeably, sometimes turning quite dark brown or grayish. This is expected and is a sign the treatment worked.

By days 5 to 7, the darkened area forms a light crust. This flakes off naturally over the following week. Picking at it delays healing and can cause scarring. By day 14, most patients see the treated area has lightened significantly. The surrounding skin looks normal. Final fading continues over weeks 3 to 6.

For patients treating the face, hands, and chest together, the hand and chest areas typically heal on the same timeline as the face. Hands can be slightly more sensitive given thinner skin, but the treatment approach is the same.

What to Expect at Your Sunspot Removal Appointment

The first step is a consultation. Your provider will examine your spots under magnification, assess their type and depth, confirm they're solar lentigines rather than other lesions requiring a different evaluation, and determine the right treatment parameters for your skin tone.

Treatment day starts with a topical numbing cream applied 20 to 30 minutes before the procedure. The PicoWay session itself is fast, typically 15 to 30 minutes for facial spots. Each pulse feels like a quick snap. Patients consistently describe it as tolerable, with the face more sensitive than the hands or chest.

After treatment, a gentle moisturizer and mineral SPF are applied before you leave. Aftercare is straightforward: keep the area clean, apply a gentle moisturizer twice daily, and wear SPF 30 or higher every morning without exception until the skin is fully healed. Sun exposure on healing skin can trigger new pigmentation and interfere with results.

How Much Does Sunspot Laser Treatment Cost?

Cost varies based on the number of spots, the treatment area (face, hands, chest, or a combination), and how many sessions your provider recommends. A patient treating three isolated spots on one cheek is a different treatment from someone addressing diffuse solar damage across the full face and décolletage.

Sunspots are one of the most satisfying things to treat with PicoWay. They're well-defined, they're superficial, and they respond fast. Most patients with a few isolated spots see them clear after a single session. The ones who've been using serums for years are usually surprised by how quickly the spot is just gone.

Frequently Asked Questions

How many sessions does it take to remove sunspots with laser?

Most isolated sunspots and age spots respond in 1 to 2 PicoWay sessions. Patients with widespread solar damage across the face, chest, or hands may need 2 to 3 sessions. Your provider will assess the depth and density of your spots at consultation and give you a specific estimate.

Can PicoWay remove sunspots completely?

Yes. Isolated solar lentigines are among the most predictably treated pigmentation conditions with PicoWay. Treated spots are typically cleared or significantly lightened after 1 to 2 sessions. New spots can form from future sun exposure, so daily SPF is essential for maintaining results.

Is laser sunspot treatment safe for all skin tones?

PicoWay is safe across a broad range of skin tones, including Fitzpatrick types III through VI. Its picosecond pulse duration generates less heat than older nanosecond lasers, reducing the risk of post-inflammatory hyperpigmentation in darker skin. Settings are always customized to your skin tone at each session.

How long does it take to see results after sunspot laser treatment?

Treated spots darken in the first 3 to 5 days as fragmented melanin rises to the surface. They then crust lightly and flake off over days 7 to 14. By two weeks post-treatment, most patients see clear improvement. Final fading continues over 4 to 6 weeks as the lymphatic system clears remaining pigment.

What is the downtime for sunspot laser treatment?

Downtime is minimal. Treated spots darken and flake over 7 to 14 days. Redness usually resolves within 24 hours. Most patients return to work the same day. Strict sun protection is required during healing to protect treated areas and prevent new pigmentation.

Will sunspots come back after laser treatment?

Treated spots do not return. New sunspots can form from ongoing UV exposure if sun protection is inconsistent. Daily SPF 30 or higher is the single most important step for maintaining results. Some patients with high cumulative sun exposure schedule one maintenance session per year.

How much does sunspot laser treatment cost at Skin Select?

Cost depends on the number of spots, the area being treated (face, hands, chest), and how many sessions your provider recommends. Pricing is discussed at consultation after your skin is assessed. You'll know exactly what's planned and what it costs before committing to anything.
