Wrinkles, sun spots, redness, and scars each answer to a different kind of laser, and a few concerns are better handled without one at first.

This guide is the wider map. It walks through five common concerns, names the technology the sources cited here pair with each one, and is plain about where the evidence is strong, where it is thin, and where a laser is the wrong first step. Several of these topics have their own deeper posts and service pages, so instead of repeating them here, we point you to the right one as we go.

• Each laser emits light of one specific wavelength, and different lasers are used for different jobs, so your concern should decide the tool.[1][3]
• For general facial rejuvenation, a pooled analysis of small randomized trials found that ablative lasers did not beat non-ablative ones on improvement or side effects.[4]
• In a review of 48 studies, lasers fully cleared sun spots in 43 percent of cases, while the AAD treats melasma first with sun protection and medicine applied to the skin.[8][9]
• For rosacea redness, pulsed dye laser and intense pulsed light performed similarly on most measures in a meta-analysis of four studies, which is a small evidence base.[7]
• Lasers can make a scar less noticeable, but the American Academy of Dermatology (AAD) is clear that they cannot remove one.[6]
• In medium to dark skin, the most common problem after non-ablative laser work was dark marks, at about 8 percent, and the risk rose with more energy.[10]

Why does your concern matter more than the machine?

The FDA describes laser light as having a specific wavelength, focused into a narrow, very intense beam.[3] That single wavelength is the point. Dermatologists use some lasers to target blood vessels, others to remove pigment, and others to resurface or tighten skin.[1] Because the jobs differ, it helps to name your concern before anyone chooses a tool.

The second variable is how much skin the laser wounds. Ablative lasers, such as carbon dioxide (CO2) and erbium (Er:YAG), resurface the skin, while non-ablative lasers, such as Nd:YAG, send heat deep into the skin without wounding the top layer.[2][4] The AAD calls laser resurfacing the most effective procedure for tightening loose skin, and notes that it requires downtime and has a greater risk of side effects such as scarring.[2]

The FDA lists the risks of laser surgery plainly: incomplete treatment of the problem, pain, infection, bleeding, scarring, and changes in skin color.[3] Notice the first one: the FDA counts incomplete treatment of the problem as a risk in its own right. That is one more reason to be clear about the concern before choosing a tool.

Which laser approach fits which skin concern?

Here is the map in one place. The second column names the technology used for each concern in the sources cited here, not every device that exists. The last column tells you where to read next, on our site or in the research.

Read down the evidence column and one pattern stands out. Several of the numbers come from reviews that pool smaller studies, and the authors of those reviews point to small samples or to differences in study design, patient groups, and treatment regimens.[4][7][8] So a pooled percentage describes the studies, not your personal odds. In two rows (melasma and raised scars), the sources describe a laser as one part of a plan rather than the whole plan.[6][9]

Wrinkles, rough texture, or loose skin: resurfacing or heat?

These three concerns are often discussed together, but the AAD describes different tools for them. Resurfacing works on the surface, and the AAD says it can diminish fine lines, wrinkles, and dark spots on the skin as well as tighten.[2] The gentler option for looseness sends heat deep into the skin while the surface stays whole.[2]

The AAD calls laser resurfacing the most effective procedure for tightening loose skin, and the one with the fastest results.[2] The cost is real: about 5 to 7 days at home, and a greater risk of side effects such as scarring.[2] The heat-only route has little downtime, but the AAD says you may need 3 to 5 treatments, with results appearing gradually 2 to 6 months after the last one.[2]

Here is the honest twist. A 2022 meta-analysis of randomized trials compared ablative lasers (erbium and CO2) with non-ablative lasers (including Nd:YAG and erbium glass) for facial and hand rejuvenation. Across 124 pooled participants, ablative lasers were not more effective and not safer.[4] The authors flagged the small samples and asked for larger trials.[4] In plain terms: in these trials, deeper was not automatically better for general rejuvenation.

If texture is your main concern, our skin resurfacing page explains the erbium options we use, and the laser facial page covers a lighter erbium peel with a shorter recovery. If firmness is the goal, read skin tightening first, then our post on how long laser skin tightening lasts, which looks at what the studies measured over time. Crepey skin right around the eyes and dry, thinning lips have their own erbium treatments, SmoothEye and LipLase, each with a page that is frank about how small its research base is.

Brown spots and melasma: why the same color gets different plans

Brown on the face is not one condition. Sun spots (solar lentigines) and melasma are two different problems. Melasma has its own triggers: the AAD lists sunlight, birth control pills, and even stress, and notes that pregnancy or a medication can set it off too.[9] They can look alike, yet the AAD and the research below handle them differently.[8][9]

For sun spots, a 2023 systematic review of 48 studies and 1,763 patients found complete clearing in 43 percent of laser-treated cases, compared with 21 percent for topical retinoids, 15 percent for freezing (cryotherapy), and 6 percent for chemical peels.[8] Combination treatments did best, at 65 percent.[8] Side effects were reported in 23 percent of laser-treated cases, and the studies varied widely in design, so read these numbers as a ranking, not a promise.[8]

Melasma flips the order. The AAD describes the most effective treatment as sun protection combined with medicine applied to the skin, sometimes with a procedure added.[9] On lasers specifically, the AAD says a few studies found that adding a laser or light treatment can help people who are already using those medicines and protecting their skin.[9] In the AAD's description, then, a laser is an add-on for melasma rather than the first step. The AAD also notes that melasma can last for years, or even a lifetime.[9]

We wrote two posts so this hub does not have to repeat them. For sun spots, including the warning signs that mean a dermatologist should see a spot before anyone treats it, read laser for dark spots. For melasma and the marks acne leaves behind, read laser treatment for melasma and dark marks, which explains why a laser used too early can make them darker. Our hyperpigmentation page covers how we sort pigment types at a visit.

Redness and small facial veins: what the comparison studies show

Redness has its own target: the blood inside small vessels. Describing light therapy for redness, the AAD says it heats up and destroys blood vessels under the skin.[1] According to the AAD, lasers can reduce rosacea, red birthmarks, broken blood vessels, and other red spots, and a dermatologist it quotes says lasers are safe for targeting blood vessels in all skin types but often require several treatments.[1] Intense pulsed light (IPL) is not a true laser, yet it is used for the same redness and enlarged facial vessels.[1]

The research comparing the two directly is small. A 2024 meta-analysis pooled four studies with 141 people with rosacea.[7] Pulsed dye laser and IPL did not differ in how often patients reached more than 50 percent clearance, and changes in redness were similar. IPL reached more than 75 percent clearance more often, while pulsed dye laser was less painful.[7] The authors called the direct comparisons limited and asked for larger, well-designed studies.[7]

Our own vascular work uses a different wavelength, a long-pulsed 1064 nm Nd:YAG laser, and the skin rejuvenation page lays out what the studies of that laser found and where it is not the first choice. The AAD lists several different red concerns that lasers treat, from rosacea to red birthmarks to broken blood vessels, so ask at your visit what is behind your redness before a setting is chosen.[1]

Can a laser fix scars? What the evidence supports

The AAD answers this directly: laser treatment cannot get rid of a scar.[6] It can make a scar less noticeable, reduce scar pain and itch, help prevent a raised scar after surgery, and improve movement when a scar limits it.[6] The AAD's framing is useful to keep in mind: you are replacing one scar with another, less noticeable one.[6]

Take pitted (atrophic) acne scars. Fractional CO2 and fractional erbium lasers are both used for them, and a 2024 meta-analysis of eight studies and 418 patients compared the two head to head.[5] Fractional CO2 had a significantly higher effective rate, but it also scored higher on pain and left redness that lasted longer.[5] The rate of dark marks afterward did not differ significantly between the two in the pooled results, although the authors' conclusion still says CO2 may carry a higher risk of pigmentation after treatment.[5]

We mention that result because our own platform uses erbium for resurfacing, not CO2, and you deserve to know how the options compare before you choose. In that same analysis, erbium was less painful and its redness faded sooner, although CO2 had the shorter overall downtime.[5] If your scars are deep or you want the strongest tool available, raise it at your visit and ask whether another option fits you better. The AAD also notes that scar plans often combine a laser with something else, such as filler for deep acne scars, and that results can take months to show.[6]

For raised scars and other scar types, the AAD says dermatologists often use more than one treatment for scars, so a laser may be one part of a combined plan.[6] Our acne and acne scars and scars and stretch marks pages explain how scar type changes the plan. Active breakouts are treated separately from scarring, on our acne treatment page.

Skin tone, safety, and choosing who treats you in Charleston

The AAD says lasers can be used on all skin types, and also that darker skin is more prone to burns and dark marks after laser treatment.[1]

A 2022 meta-analysis of 43 studies and 1,654 people with Fitzpatrick skin types IV to VI found the overall rate of side effects from non-ablative lasers and similar devices was low.[10] Dark marks after treatment (post-inflammatory hyperpigmentation) were the most common problem, at 8.1 percent, and they rose with darker skin type, denser laser settings, and more total energy.[10] The authors found diode, Q-switched Nd:YAG, and erbium-doped lasers tended to have higher rates, while IPL and radiofrequency carried minimal risk.[10]

Preparation is part of the plan too. Before treatment, the AAD says you may need to stop topical retinoids, stop smoking, or start an antiviral or antibiotic your clinician prescribes, and you should list every product, medicine, and supplement you use, because some make skin more sensitive to laser light.[1] For scars, the AAD adds stopping vitamin E, aspirin, and other medicines and supplements that can delay healing, and pausing retinoid or glycolic acid products for 2 to 4 weeks.[6] A tan or sunburn on treatment day means no treatment.[6] Our post on what to expect from your first laser treatment walks through the weeks before and after in order.

The person holding the laser counts too. The AAD puts it simply: results depend largely on the skill of whoever performs the procedure.[1] It also warns that a consult should come before any laser scar treatment, and that a promise to treat without one is a reason to walk away.[6] At Solcara, laser plans are set by Ashley Harwyn, PA-C, who is board certified in anti-aging and functional medicine through A4M and holds the ABAAHP credential.

Our platform is a Fotona system that pairs an erbium laser with a 1064 nm Nd:YAG laser. Our service pages describe what we use each one for: the erbium laser for skin resurfacing, the laser facial, SmoothEye, and LipLase, and the 1064 nm laser for brown spots, small red veins, and finely lined skin on the skin rejuvenation page. If a technology on the map, such as CO2, pulsed dye, or IPL, is not among the services listed on our site, ask at your visit how it compares for your concern.
