Red Light Therapy for Age Spots: Tone, Safety and Set-Up
Red light therapy for age spots is best seen as support for a more even skin tone, not as a way to remove the spots themselves. Dermatologists list dark spots among the concerns LED red light may help, while lasers, IPL, freezing and prescription creams remain the tools that fade individual spots. Below: spot checks, light colours, study settings, hands, darker skin, clinic treatments, timelines and set-up.

Does red light therapy for age spots work?
It can support a more even tone in skin with age spots, but it is not a spot remover. The closest evidence comes from facial studies that measured overall tone and signs of sun damage, not individual spots.
Age spots, also called liver spots, sun spots or solar lentigines, are flat, oval patches from tan to dark brown. They range from freckle size to about 13 mm and appear on the face, hands, shoulders, arms and upper back. Mayo Clinic, 2025
"Age spots are not harmful." Harvard Health, 2026 Treatment is a cosmetic choice.
| Type of evidence | What it showed | What it means for age spots |
|---|---|---|
| Human face studies | More than 90% of 90 patients reported improvement, including lighter dark spots (AAD summary); tone 34.9% more even at 12 weeks (Couturaud, 2023) | Support for overall tone and sun-damaged skin |
| Expert consensus | A 21-expert consensus says light "can be used for skin rejuvenation" | Skin quality is a recognised use |
| Colour comparisons | 630 nm red did not darken skin; 415 nm violet did | Choose red, keep blue low or off |
| Lab and animal work | 660, 830 and 850 nm lowered melanin or its key enzyme | A plausible way light could influence pigment |
The consensus figure comes from Maghfour, 2025.
In human pigment cells, 830 nm and 850 nm light significantly reduced melanin and tyrosinase, the enzyme that makes it. Kim, 2012 A 660 nm LED reduced UVB pigment in hairless mice. Oh, 2017
A 2024 review found red light "more effective in reducing blemishes and dark stains", and near-infrared better for elasticity and wrinkles. Hernández-Bule, 2024 See our guide to red light therapy for hyperpigmentation for dark marks generally.
How do you tell an age spot from skin cancer before using light?
Have a doctor look at any spot that is new, changing, growing, bleeding, itchy, black, multicoloured or irregular before you use any light on it. True age spots are flat, evenly coloured and stable, and a quick check rules out lookalikes.
The AAD warns that treating a skin cancer as an age spot can let it grow and spread. AAD, 2021 Its melanoma checklist is a useful guide:
- Asymmetry: "One half of the spot is unlike the other half."
- Border: irregular, scalloped or poorly defined.
- Colour: varying shades within one spot.
- Diameter: usually greater than 6 millimetres, though melanomas can be smaller.
- Evolving: a spot that changes in size, shape or colour. AAD ABCDEs
The NHS adds a new skin mark that has not gone away after a few weeks, or one that is painful, itchy, bleeding or crusty. NHS
Lentigo maligna, an early melanoma, appears on sun-damaged faces, with peak diagnosis between 60 and 80. Early on it "often resembles common freckles or brown marks". DermNet, 2023 A doctor can tell them apart. Mayo Clinic, 2025
Rough, scaly patches may be actinic keratoses rather than age spots. Our article on red light therapy for sun damage explains why those need a GP.
Can an LED mask make age spots darker?
Red light has not darkened skin in the studies that compared colours, but blue and violet light can. Anyone prone to dark marks should use the mask's red mode and leave the blue mode off.
In the colour comparison, 630 nm red "did not induce hyperpigmentation", while 415 nm violet light raised pigment as the dose increased. Photochem Photobiol Sci, 2020
In an acne study, 633 nm red light significantly decreased melanin, while 415 nm blue slightly increased it. He, 2023
In human skin cells, 457 nm blue light raised a pigment-signalling hormone 1.31-fold. Barolet, 2025
Our mask's blue mode uses 460 nm, and the panel has a 480 nm channel. Both sit in the blue band, so for skin with age spots use the red mode and turn the panel's 480 nm channel to its lowest. Our melasma article maps each colour to its setting.
In a 2019 study of 72 people, standard UV filters did not protect against visible light. Kohli, 2019 The AAD suggests a tinted sunscreen with iron oxide, SPF 30 or higher. AAD, 2025
What settings did the skin tone and pigment studies use?
Most face studies used red or near-infrared light about twice a week for 4 to 12 weeks. Sessions in the mask study lasted 12 minutes.
| Study | Light | Dose | Session | Schedule | Main result |
|---|---|---|---|---|---|
| Couturaud, 2023 (20 adults, no control) | 630 nm LED mask | 15.6 J/cm² | 12 minutes | 2 a week, 12 weeks | Tone 34.9% more even |
| Lee, 2007 (76 people, sham split face) | 633 nm, 830 nm or both | Not given in abstract | Not given | 2 a week, 4 weeks | Wrinkles down up to 36%, elasticity up to 19% |
| AAD summary (90 patients) | LED light | Not given | Not given | 8 sessions in 4 weeks | Over 90% improved, including lighter dark spots |
| Acne study (via He, 2023) | 633 nm red | 96 J/cm² | Not given | 2 a week, 4 weeks | Melanin decreased |
| Colour comparison (via reviews) | 630 nm vs 415 nm | 10 to 150 J/cm² red | Single exposures | Single | No new pigment with red |
The split-face trial is described in its abstract, Lee 2007.
Trial doses do not convert into a home session. What carries over: red light, regular sessions, 8 to 12 weeks.
Does red light therapy for sun spots on the backs of the hands help?
The closest evidence comes from face and neck studies, since the backs of the hands have not been studied on their own. The hands are a classic site for sun spots, and the panel is the Kivorla device that reaches them.
Harvard Health notes that age spots commonly show up on the hands. DermNet lists the backs of the hands and forearms among the most usual sites. DermNet, 2024
The AAD says age spots on the hands tend to grow larger with sun. AAD, 2023 Its advice for hands:
- Sunscreen: broad-spectrum, water-resistant SPF 30 or higher on the backs of the hands every day.
- Driving: a thin sun-protective glove, since hands on the wheel get steady sun.
For a panel session, rest both forearms in front of the panel at about 12 inches, palms down. The 6-inch distance in our hands and feet guide is for a joint. Wear the goggles even though your face is not the target.
Is red light safe for age spots on darker or Asian skin?
Start lower and see a dermatologist first, because darker skin is more sensitive to visible light and can mark more easily. Our panel is not for Fitzpatrick skin types V or VI.
The AAD notes that darker skin is "more sensitive to visible light, such as red light", and that dark spots from visible light can be more intense and longer-lasting. AAD, 2024 Harvard Health advises people with darker skin to "start with lower doses". Harvard Health, 2025
Solar lentigines are common in Asian populations, often on the face, and harder to see on darker skin. DermNet, 2024
With the mask, begin in the red mode at 50% brightness with the 5-minute timer. Stop if nearby skin turns darker.
How does red light compare with laser, IPL, freezing and fade creams?
They do different jobs: clinic treatments and prescription creams fade individual spots, while red light supports overall tone. You can pair a dermatologist's treatment with daily sunscreen and add light for skin quality.
| Option | Typical course | Trade-offs |
|---|---|---|
| Laser or IPL (clinic) | Typically 2 to 3 sessions | Crusting and temporary darkening |
| Freezing with liquid nitrogen | 5 seconds or less per spot | Blister and redness; rare permanent darkening, lightening or scarring |
| Prescription creams | Hydroquinone, often with tretinoin and a mild steroid, over several months | Itching, redness, burning or dryness |
| Chemical peel | 47% had 50% fading in one comparison | Risk of scarring, lightening or darkening |
| LED red light (home) | Several times a week for months | Supports overall tone; does not remove spots |
Courses and side effects come from Mayo Clinic, 2025 and the AAD, 2021.
A 2025 systematic review of clinical trials judged lasers the most effective option, with mostly mild side effects. Mardani, 2025
If you buy a fade cream, avoid any product containing mercury. Cleveland Clinic lists names such as calomel and quicksilver. Cleveland Clinic, 2021
Can you use red light after freezing or laser, or alongside fade creams?
After a clinic treatment, follow your dermatologist's aftercare and keep light off any blister, crust or scab until the skin has fully healed. With creams, use light first on bare skin and apply the cream afterwards.
The AAD reports that patients who had in-office red light after laser treatment had less discolouration and swelling. AAD, 2024 No source sets a waiting time for home light after freezing or laser, so ask the clinic when your skin is ready.
- Morning order: cleanse, light, serum or fade cream, moisturiser, then sunscreen.
- Evening order: cleanse, light, then your prescription cream.
- Irritated skin: hydroquinone can cause redness or burning, so skip sessions while skin is red, raw or peeling.
Our guide to masks, makeup and sunscreen covers the full routine. Harvard Health advises avoiding red light with light-sensitising medicines such as certain antibiotics. Our precautions rule out use with photosensitising medication, so if you take a medicine or use a prescription cream, check with your pharmacist or doctor before using the device.
How long does red light take to even out tone around age spots?
Expect weeks to months: in the 12-week mask study, tone had not changed at week 4 but was 32.7% more even by week 8. Harvard Health suggests home devices are used multiple times a week for four to six months.
By week 12 the gain reached 34.9%. Results held 28 days after people stopped. Couturaud, 2023
- Photos: weeks 0, 4, 8 and 12, same light and position, no makeup.
- Decision: compare week 12 with week 0.
Can red light prevent new age spots, and do old ones fade on their own?
Prevention is sun protection, not light: red light makes no UV and gives no UV protection. Existing age spots often lighten over time but probably will not disappear completely.
Mayo Clinic's prevention advice:
- Timing: avoid the sun between 10 in the morning and 2 in the afternoon.
- Sunscreen: broad-spectrum SPF 30 or higher, 15 to 30 minutes before going out, reapplied every two hours.
- Clothing: UPF 40 to 50 fabrics and a broad-brimmed hat. Mayo Clinic, 2025
Harvard Health says reducing sun exposure can keep existing spots from growing or darkening. Unlike freckles, age spots do not fade in winter.
Despite the name, liver spots are unrelated to liver function. Cleveland Clinic, 2021
How do you use a Kivorla mask and panel for age spots?
Use the mask's red mode for spots on the face and the panel for the backs of the hands and forearms, starting low and short. Keep the same routine for 8 to 12 weeks and compare photos.
The 4-Wavelength Red Light Therapy Mask is a cordless, full-face silicone shell with an eye opening and no diodes over the eyes.
- Mode: the red mode (665 nm red with 850 and 1064 nm near-infrared). Leave the blue mode (460 nm with 850 nm) off for skin with age spots.
- Week 1: 50% brightness, 5-minute timer, on clean, dry, bare skin.
- Building up: if skin stays even, move to 10-minute sessions up to 4 times a week at high brightness, or 15-minute sessions up to 3 times a week after three 10-minute sessions the week before. Never more than 20 minutes a day.
- Eyes: keep them closed and never look into the light.
The 9-Spectrum Red Light Therapy Panel carries 480, 590, 630, 660, 670, 810, 830, 850 and 1060 nm, each dimmable from 1 to 100%.
- Position: hang it on a door or wall with the included door hook and pulley, or stand it upright on the floor (a stand is sold separately).
- Hands and forearms: about 12 inches away, palms down, goggles on.
- Channels: 480 nm at its lowest and the others dimmed well below full to start.
- Timer: from 1 minute, working towards 10 to 15 minutes per area if skin stays calm. Leave at least 6 hours between 30-minute sessions.
- Not for: Fitzpatrick skin types V or VI, or after sunburn on the body in the past 2 weeks.
Stop and see a dermatologist if the spots or the skin around them darken, redness does not settle, or skin stings or burns. Goggles and a controller come with the panel; see our goggles guide for why they matter.
