1. Does red light therapy really help fade dark spots?
Yes. It cannot bleach pigment directly, but it improves cellular renewal and skin healing, which gradually fades dark spots.
2. How long does it take to see results?
Most people see improvements in 4–12 weeks with consistent use.
3. Can red light therapy treat melasma?
It may help mild melasma by reducing inflammation, but severe melasma often requires dermatologist-guided treatment.
4. Is red light therapy safe for all skin tones?
Yes. Red light therapy is safe for every skin tone and does not increase pigmentation like some lasers.
5. Can red light therapy prevent new dark spots?
It can reduce inflammation and repair sun damage, indirectly lowering the chance of new spots forming.
6. Can I use red light therapy every day?
Yes. Daily use is safe, though 3–5 sessions per week are generally enough.
7. Does red light therapy replace sunscreen?
No. You must still use sunscreen to prevent hyperpigmentation from returning.
8. Will red light therapy irritate my skin?
No. It is non-invasive, non-heating, and safe even for sensitive skin.
9. Can I combine red light therapy with skincare products?
Yes—Vitamin C, niacinamide, and peptides work especially well with red light therapy.
10. Which type of device works best for dark spots?
High-quality LED systems with 630–660 nm wavelengths—like MERICAN’s devices—provide optimal results for pigmentation and skin tone improvement.
