Terapia de luz roja (RLT), también conocido como terapia de luz de bajo nivel (LLLT) o fotobiomodulación, is widely considered safe and non-invasive. Sin embargo, like any treatment, there are some potential side effects and precautions you should be aware of.
Efectos secundarios comunes

- Skin Redness or Warmth
- Some users notice mild pinkness or warmth in the treated area.
- Typically resolves within a few hours.
- Eye Strain or Discomfort
- Direct exposure to bright red or near-infrared light can irritate the eyes.
- Use protective goggles during treatment, especially with high-intensity panels or beds.
- Dry Skin or Flakiness
- Red light may slightly increase skin cell turnover, which can cause temporary dryness.
- Hidratación after treatment to prevent irritation.
- Mild Headache

- Temporary Worsening of Acne or Skin Conditions
- Some people experience initial purging as skin renews itself.

- Skin disorders: Conditions like lupus or porphyria may react badly to light therapy.
