1. How does red light therapy work on KP at the cellular level?
It improves mitochondrial function and reduces local inflammation, leading to smoother skin and improved texture.
2. Does RLT help with the dryness associated with KP?
Yes. It strengthens the skin barrier and improves moisture retention.
3. What wavelengths are best for KP?
630–660 nm (red) and 810–850 nm (near-infrared) provide optimal skin benefits.
4. Should I exfoliate before or after RLT?
Use gentle exfoliation before treatment and moisturize afterward for best absorption.
5. Can RLT reduce KP on the face?
Yes. It is safe for facial KP, common on cheeks.
6. Is daily use safe?
Yes, but most users benefit from 3–5 sessions weekly.
7. Does RLT help prevent KP flare-ups?
Regular use improves skin barrier function, reducing future flare-ups.
8. Can children or teens use red light therapy for KP?
RLT is generally safe, but younger users should consult a healthcare provider.
9. Should I use a handheld device or a panel?
Panels or full-body systems like Merican RLT panels provide more even, efficient coverage than small handheld units.
10. What results can I realistically expect?
Smoother skin, reduced bumps, less redness, and better overall texture with consistent use.
