Sunburn is UV radiation damage to the skin, causing redness, pain, and inflammation. Red light therapy can't undo the UV damage, but it can reduce the inflammatory response and speed healing. The key is using it correctly — at the right time and intensity.

The Science

Red light therapy helps sunburn through:

  • Reduced inflammation: RLT lowers inflammatory cytokines in sunburned skin
  • Improved circulation: Better blood flow brings healing nutrients
  • Cellular repair: RLT stimulates fibroblasts to repair UV-damaged skin
  • Pain reduction: Anti-inflammatory effect reduces sunburn pain

Important: RLT does NOT reverse UV damage to DNA. Sunscreen prevention is always better than treatment.

The Sunburn Protocol

  1. Cool the burn first. Cool compress or cool shower for 10–15 minutes to reduce heat.
  2. Apply aloe vera gel. Soothes and hydrates sunburned skin.
  3. Use RLT 24–48 hours after sunburn. Don't use immediately — let initial inflammation peak.
  4. Treat for 5–10 minutes per area, 2x daily. Use lower intensity — sunburned skin is sensitive.
  5. Apply moisturizer after RLT. Hydrated skin heals faster.
  6. Stay out of the sun until healed. Prevent further UV damage.

When to Use RLT

Don't use RLT immediately after sunburn. The initial inflammatory response (first 12–24 hours) is part of the healing process. Wait 24–48 hours before starting RLT.

Best timing: 24–48 hours after sunburn, when inflammation has peaked but hasn't started resolving.

Use lower intensity: Sunburned skin is sensitive. Use a panel from 12+ inches away, or use a low-intensity mask setting.

Frequently Asked Questions

Yes — RLT can reduce sunburn inflammation and speed healing. Best used 24–48 hours after sunburn, not immediately.
No — wait 24–48 hours. The initial inflammatory response is part of healing. RLT works best once inflammation has peaked.
No — RLT can't reverse UV damage to DNA. It reduces inflammation and speeds healing, but prevention (sunscreen) is always better.
For face sunburn: HigherDOSE mask ($249). For body sunburn: MitoMIN panel ($199) — use from 12+ inches away on low intensity.
No — RLT doesn't provide UV protection. Sunscreen (SPF 30+) is the only way to prevent sunburn.
Consult a doctor for severe sunburn with blisters. RLT may help healing but severe sunburn requires medical evaluation.
