The Difference Between Red Light Therapy and Tanning Beds
They look alike. Both are bed-shaped devices you lie inside, and both emit visible light. That is where the similarity ends. A red light therapy bed and a UV tanning bed operate on different parts of the electromagnetic spectrum, trigger different biological responses, and carry different risk profiles. Confusing the two is common, but the distinction matters if you care about your skin health.
- "Red light tanning beds" is a misleading term. Red light therapy beds use wavelengths around 630 to 660 nanometers and do not tan your skin. Traditional tanning beds emit ultraviolet light (280 to 400 nm) to darken skin through melanin production.
- UV exposure from tanning beds is associated with increased risk of premature aging and skin cancer. Red light therapy does not emit UV light and does not carry UV-related risk.
- Red light therapy focuses on skin health, collagen production, and muscle recovery. Results are gradual and require multiple sessions. Tanning beds produce immediate color changes but accumulate UV damage over time.
- Red light therapy is considered safe with minimal side effects when used at appropriate doses with proper eye protection.
- Body Balance Medical in Las Vegas, Henderson, and Summerlin offers medically supervised red light therapy sessions and does not offer UV tanning beds.
Red Light Therapy vs. Tanning Beds: The Core Difference
Red light therapy beds and UV tanning beds may sit in the same category of "light-based devices," but they use completely different types of light with very different effects on skin cells.
- Tanning beds emit ultraviolet light, specifically UVA rays (320 to 400 nm) and UVB rays (280 to 320 nm). This UV light triggers melanocytes to produce melanin, creating a darker skin tone. That same UV exposure is associated with premature aging and higher skin cancer risk.
- A red light therapy bed uses visible red wavelengths (around 630 to 670 nm) and often near-infrared light (around 800 to 850 nm). These wavelengths sit entirely outside the UV range and do not tan or burn skin.
- UV light damages DNA in skin cells and stresses the skin's surface. Red light therapy is designed to support cellular repair, collagen synthesis, improved circulation, and muscle recovery, without any UV radiation.
The phrase "red light tanning beds" blurs these distinctions. Any device producing a true tanning effect must use UV light. Red light alone does not create a bronzed glow because it does not activate the tanning process. If a device you are using produces a lasting change in skin color, UV is involved somewhere in its output.
Understanding Red Light Therapy
Red light therapy, also called low-level light therapy or photobiomodulation (PBM), is a non-UV treatment used in dermatology, sports medicine, and wellness centers. Its wavelengths, from roughly 600 to 850 nm, place it well outside the ultraviolet spectrum.
- Red and near-infrared wavelengths are absorbed by cytochrome c oxidase inside mitochondria. This interaction increases cellular energy (ATP) and stimulates cellular activity involved in natural repair processes.
- Typical wavelengths used in professional red light therapy beds range from 630 to 700 nm for red light and 800 to 850 nm for near-infrared. None of these are ultraviolet.
- Common goals include improving skin texture and tone, supporting collagen production, easing muscle and joint discomfort, and helping with post-exercise recovery.
- Red light therapy enhances cellular repair and circulation at the tissue level, which is why it appears in clinical and athletic recovery settings alongside standard care.
The broader evidence base for photobiomodulation is covered on our red light therapy benefits page, including how the mechanism translates to specific skin and recovery goals.
How Tanning Beds Work
Tanning beds are designed to darken skin by exposing it to artificial UV light, replicating some effects of direct midday sun exposure.
- Tanning bulbs emit both UVA and UVB. UVA rays penetrate deeper into the skin, creating immediate pigment darkening. UVB rays contribute to delayed tanning and sunburn.
- UV light activates melanocytes to produce melanin, which creates the bronzed appearance. That melanin production is also a signal that the skin is responding to damage. The tanning process itself is a marker of UV injury.
- The FDA reclassified indoor tanning devices as Class II medical devices in 2014, imposing warning labels, exposure schedules, and restrictions for users under 18.
- Repeated tanning bed use is associated with premature aging and increased skin cancer risk. UV exposure accelerates changes in skin texture, elasticity, and pigmentation evenness over time.
- Tanning beds are cosmetic devices focused on color, not on long-term skin wellness. Body Balance Medical does not provide UV tanning beds.
Key Differences at a Glance
| Feature | UV Tanning Bed | Red Light Therapy Bed |
|---|---|---|
| Light type | UV (280 to 400 nm) | Red and near-infrared (630 to 850 nm) |
| Biological effect | Melanin production, DNA damage | Mitochondrial support, collagen synthesis |
| Visible outcome | Fast tan, fades in days | Gradual skin quality changes over weeks |
| UV exposure risks | Burns, premature aging, skin cancer risk | None (no UV emitted) |
| Session frequency | 1 to 2 sessions for visible tan | Multiple sessions for cumulative results |
| Regulatory status | FDA Class II medical device, 2014 | Varies by device; clinical beds follow manufacturer protocol |
Results from red light therapy are gradual, typically across 4 to 12 weeks of consistent sessions. "Red light tanning" is a marketing phrase, not a scientific description. Unlike a UV tanning bed, a red light bed does not darken your skin.
Does Red Light Therapy Tan You?
No. A true red light therapy bed does not tan your skin because it does not emit UV light and does not stimulate melanin production.
Red and near-infrared wavelengths pass through the epidermis and interact with mitochondria, not melanocytes. Melanocytes respond to UV radiation by producing melanin. Red wavelengths at 630 to 660 nm do not trigger that pathway at all.
After a red light therapy session, skin may look temporarily flushed or more even. That is from increased blood flow and hydration at the skin's surface, not from pigment change. It is not a tan and it is not skin damage. The temporary flush fades within an hour and does not represent UV injury.
What about hybrid tanning beds? Some tanning salon environments combine UV bulbs and red light LEDs in a single unit. These carry the same risks as standard UV tanning because the tan comes from the UV component. Red light in the same device does not cancel or offset UV damage. If a device gives you a lasting darker skin tone, UV is doing the work.
People with sensitive skin often tolerate dedicated red light therapy better than UV tanning because there is no burn risk, though provider guidance and eye protection still apply.
Health and Safety: UV Risk vs. Red Light Therapy
UV tanning beds and non-UV red light therapy beds carry very different risk profiles. The distinction is straightforward: one emits a known carcinogen, the other does not.
- UV exposure is associated with increased risk of basal cell carcinoma, squamous cell carcinoma, and melanoma. The International Agency for Research on Cancer (IARC), part of the World Health Organization, classifies tanning beds as a Group 1 carcinogen, meaning they are known to cause cancer in humans. This places them in the same classification category as tobacco. Frequent tanning bed use increases lifetime UV burden with each session.
- Red light therapy does not include UV light, so it does not cause UV-type sunburn, does not produce a tan, and is not linked to UV-related skin cancer risk when used appropriately. Red light therapy is considered safe with minimal side effects at therapeutic doses.
- Direct exposure to high-intensity red light may cause retinal strain, which is why eye protection is required at every session. Proper dosing and device quality also matter. These are manageable factors in a supervised clinical setting and are not comparable to the cumulative UV risk of a regular tanning routine.
- Individuals on photosensitizing medications should discuss red light therapy with a provider before starting, since some medications increase sensitivity to light broadly.
Benefits of Red Light Therapy for Skin and Recovery
Many patients choose red light therapy for skin support and overall wellness, not for a tanning effect. The therapeutic applications target cellular function, not pigment.
- Red light therapy promotes collagen production and skin healing. A randomized, double-blinded study found that LED treatment at 633 nm and 830 nm produced measurable increases in collagen and elastin fibers after twice-weekly sessions over four weeks.
- It may complement care for acne, redness, and skin texture concerns when overseen by a medical provider, though individual responses vary. It supports skin rejuvenation goals through cellular mechanism rather than surface color change. Patients managing skin aging and volume loss are among those who explore it most consistently.
- Near-infrared wavelengths penetrate deeper tissues and are used in sports medicine and physical therapy settings to support muscle recovery after activity.
- At Body Balance Medical, red light therapy may be combined with other in-clinic services like IV therapy as part of a broader approach to skin health and recovery. It is not a replacement for medical treatment of diagnosed conditions.
Legitimate Uses of Each Device
Both devices have defined roles. Choosing between them depends on the primary goal: cosmetic color versus skin wellness and recovery support.
- UV tanning beds are cosmetic tools for people who prioritize a bronzed appearance and accept the UV exposure risks. Multiple public health organizations discourage routine indoor tanning because of cumulative UV radiation effects. A tanning session delivers fast, visible color. A regular tanning routine adds lifetime UV exposure with each visit.
- Tanning beds are not designed for skin healing, collagen support, or muscle recovery and should not be treated as therapeutic devices.
- Red light therapy beds are used in clinical and wellness settings for skin health and collagen support, managing discomfort, and muscle recovery. Red light therapy works by supporting cellular function rather than altering pigment.
- Body Balance Medical provides red light therapy and not UV tanning, which reflects the clinic's focus on long-term skin support and overall well-being rather than short-term cosmetic color.

In-Clinic vs. At-Home Devices
Patients often compare in-clinic red light therapy beds with smaller at-home red light devices, as well as with tanning salon memberships.
- Professional red light therapy beds provide full-body coverage and consistent power output, which is more efficient than small panels or masks used at home. Clinical devices deliver appropriate irradiance per session more reliably than consumer products, which vary widely in wavelength accuracy and build quality.
- At-home red light devices may be helpful for maintenance between in-clinic sessions, but they should not be confused with UV tanning equipment or marketed as red light tanning beds. The distinction in mechanism and risk profile is the same whether the device is small or large.
- Body Balance Medical focuses on clinically supervised red light therapy and does not recommend UV tanning methods as a skin care, skin health, or long-term wellness strategy.
Frequently Asked Questions
Does red light therapy give you a tan?
No. Red light therapy does not produce a tan because it uses specific wavelengths (630 to 850 nm) that sit entirely outside the UV spectrum. Without UV light, melanocytes are not triggered to produce melanin, which is the pigment responsible for tanning. Any post-session flush or glow comes from increased circulation and skin hydration, not from pigment change. This temporary effect fades within an hour and does not represent UV damage or a tanning effect. If a device gives you a lasting darker skin tone, UV is involved in that device's output.
Can red light therapy cause UV damage or skin cancer?
True red light therapy beds do not emit UV rays, so they are not associated with UV-type DNA damage or the skin cancer risk linked to UV tanning. Red light wavelengths do not carry enough photon energy to create the pyrimidine dimers (DNA lesions) that UV light produces in skin cells. Red light therapy should still be used as directed, with proper eye protection and at appropriate dosing. No light-based treatment is entirely without considerations, but the UV-specific risks associated with tanning bed sessions do not apply to red light therapy.
Is red light therapy safer than a tanning bed?
From a skin cancer and premature aging standpoint, red light therapy does not carry the UV-related risk that tanning beds do. Traditional tanning beds add to lifetime UV exposure with each session, and prolonged use is linked with higher rates of melanoma, squamous cell carcinoma, and basal cell carcinoma in epidemiologic studies. Red light therapy does not contribute to cumulative UV burden. Skin sensitivity to red light is lower than to UV, though individuals on photosensitizing medications should speak with a provider before starting any light-based treatment.
Can I use a tanning bed and red light therapy in the same session?
Some tanning salons and wellness centers allow both in the same visit, but combining them still means adding UV from the tanning bed. The red light portion does not cancel or offset UV damage from the tanning component. If you combine red light therapy with a UV tanning session, the UV exposure risks remain. Anyone considering this should speak with a medical provider, especially if they have fair or sensitive skin, a history of skin cancer, or take medications that increase light sensitivity.
What is near-infrared light, and does it tan skin?
Near-infrared light occupies wavelengths just beyond visible red, roughly 700 to 1,200 nm. It penetrates more deeply into tissue than visible red light, reaching muscles, joints, and deeper dermal layers. Near-infrared wavelengths support circulation, muscle recovery, and tissue repair. They do not tan skin because they fall well outside the UV spectrum and do not activate melanocytes or stimulate melanin production. Near-infrared light is a core component of many clinical red light therapy beds and is used in sports medicine and physical therapy for recovery, not for any cosmetic tanning purpose.
