Red light therapy and tanning beds are often found in the same wellness or beauty settings, but they serve very different purposes. While tanning beds are designed to darken the skin using ultraviolet (UV) radiation, red light therapy focuses on skin health and cellular support without UV exposure.
Understanding the difference is essential for choosing the right treatment—or combining them safely.
What Is a Tanning Bed?
A tanning bed uses ultraviolet (UV) radiation, primarily:
-
UVA (95–99%) for skin darkening
-
Small amounts of UVB that can cause sunburn
Primary purpose:
-
Create a darker skin tone (tan)
Key characteristics:
-
Fast, visible tanning
-
High UV exposure
-
Increased risk of skin aging and skin cancer
What Is Red Light Therapy?
Red light therapy uses non-UV wavelengths, typically:
-
Red light (around 630–660 nm)
-
Near-infrared light (around 810–880 nm)
Primary purpose:
-
Support skin rejuvenation
-
Promote collagen production
-
Improve circulation and muscle recovery
Key characteristics:
-
No tanning effect
-
No UV radiation
-
Safe for regular use when used properly
Red Light Therapy vs Tanning Beds: Key Differences
| Feature | Tanning Beds | Red Light Therapy |
|---|---|---|
| Light type | UV (UVA/UVB) | Red & Near-Infrared |
| Tanning effect | Yes | No |
| Skin aging risk | High | None from UV |
| Collagen support | No (breaks down collagen) | Yes |
| Cancer risk | Increased | No UV-related risk |
| Use frequency | Limited | Can be frequent |
Which One Works Faster?
-
Tanning beds produce visible color quickly—sometimes within a few sessions
-
Red light therapy produces gradual improvements in skin quality over weeks
Speed depends on your goal:
-
Faster color → tanning beds
-
Safer skin improvement → red light therapy
Is Red Light Therapy Safer Than Tanning Beds?
Yes. From a dermatological and safety standpoint:
-
Red light therapy does not damage DNA
-
It does not suppress melatonin
-
It does not increase skin cancer risk
Tanning beds, by contrast, are classified by health organizations as carcinogenic due to UV exposure.
Can Red Light Therapy Be Used With Tanning Beds?
Yes—when used carefully and not as a replacement for sun protection.
Many professional salons and wellness centers offer:
-
Red light therapy before or after tanning
-
Red light to support skin appearance and recovery
-
Reduced reliance on frequent UV tanning sessions
This combination is often positioned as a more balanced approach, though UV exposure should still be minimized.
Which Is Better for Long-Term Skin Health?
If long-term skin health is the priority:
-
Red light therapy is the better option
-
It improves skin quality without UV damage
-
Suitable for clients who want glow without tanning
Tanning beds may offer cosmetic results, but at the cost of cumulative skin damage.
Final Verdict
Red light therapy and tanning beds are not interchangeable.
-
Tanning beds = faster color, higher risk
-
Red light therapy = no tanning, safer skin support
For modern beauty and wellness consumers, red light therapy is increasingly viewed as the health-focused alternative, while tanning beds are used more selectively—or avoided altogether.
