1. Can red light therapy remove dark spots permanently?
It can fade and reduce pigmentation, but permanent results depend on the cause and consistent use.
2. How long does it take to see improvement?
Most users notice brighter skin and reduced spots after 4–6 weeks of consistent sessions.
3. Is red light therapy safe for melasma?
Yes, but results vary. It helps reduce inflammation and even skin tone when used under professional guidance.
4. Can red light therapy make pigmentation worse?
No. Unlike UV or IPL, it’s non-thermal and non-UV, meaning it won’t trigger more pigment production.
5. What wavelength is best for pigmentation?
Wavelengths between 630–660 nm (red) and 810–850 nm (near-infrared) are most effective for skin healing and tone balance.
6. Can I combine red light therapy with skincare products?
Yes. Use antioxidants or brightening serums after your session to enhance results.
7. Is red light therapy suitable for all skin types?
Absolutely — it’s safe for all skin tones and doesn’t cause burns or irritation.
8. Can red light therapy help post-acne pigmentation?
Yes. It promotes healing and reduces inflammation, helping fade post-acne marks naturally.
9. Should I use sunscreen after red light therapy?
Yes! Even though RLT is UV-free, protecting skin from sunlight prevents new pigmentation.
