How Red Light Therapy Works on the Skin
Red light therapy uses wavelengths typically between 630–660nm (and sometimes near-infrared up to 850nm) to penetrate the skin and stimulate cellular activity. It helps boost collagen production, meningkatkan peredaran, and support skin repair.

What Does Sunscreen Do?
Sunscreen is designed to protect the skin from harmful ultraviolet (UV) sinaran. It works by:
- Absorbing UV rays (chemical sunscreens)
- Reflecting or scattering light (mineral sunscreens like zinc oxide or titanium dioxide)
Although red light is not UV, sunscreen can still act as a physical or chemical barrier on the skin, which may affect light penetration.
Does Sunscreen Block Red Light Therapy?
1. Reduced Light Penetration
Sunscreen—especially mineral formulas—can partially block or reflect light, including some red and near-infrared wavelengths. This means:
- Less light reaches deeper skin layers
- Treatment effectiveness may be reduced
2. Uneven Absorption
If sunscreen is applied unevenly, it can lead to inconsistent exposure across the skin, resulting in uneven treatment outcomes.
3. Product Layer Interference
Thick layers of skincare products (including sunscreen) may create a barrier that limits how much light energy your skin absorbs.
Should You Use Sunscreen During a Session?
