赤色光療法 (RLT) is famous for skin rejuvenation and pain relief—but can it actually give you asun-kissed glow like UV tanning? Let’s debunk the myths and reveal what science says.
1. The Short Answer
× いいえ, red light therapy does NOT tan your skin.
√ But it may enhance your natural complexion by improving circulation and collagen.
Why RLT Doesn’t Cause Tanning
- No UV rays – Tanning requires UVA/UVB exposure (RLT uses only visible red and near-infrared light).
- No melanin stimulation – Unlike UV light, RLT doesn’t trigger pigment-producing melanocytes.
2. Why Some PeopleThink RLT Tans Them
あ. Temporary “Glow” 効果
- Increased blood flow can make skin appear slightly rosier or brighter post-session.
- Collagen plumping may give a healthier, more radiant look (but not a true tan).
B. Misleading Marketing
- Some devices combine RLT + 紫外線 (rare, but check specs to avoid accidental UV exposure).
3. How to Safely Get a TanWhile Using RLT
If you want both RLT benefitsそして a tan:
- Use a self-tanner (RLT won’t interfere).
- Try a bronzing serum (例えば, with DHA).
- Get occasional UV tanning (but minimize risks with SPF).
⚠️Never use UV beds frequently—they age skin and increase cancer risk.
4. What RLTActually Does for Skin Tone
✔Reduces redness (great for rosacea).
✔Fades hyperpigmentation (sun spots, melasma).
✔Improves texture (less dullness, more glow).
Final Verdict
| Claim | True or False? |
|---|---|
| “RLT gives a UV-like tan.” | False |
| “RLT makes skin look healthier.” | True |
| “You can combine RLT with self-tanners.” | True |
Bottom Line:
RLT enhancesnatural radiance, but for a real tan, you’ll need UV exposure (use caution!) or self-tanners.
