Red Light Therapy for Sunburn and Skin Healing

Red light therapy is well known for supporting skin healing, so people often ask whether it helps with sunburn. The answer is nuanced.

Red light and the skin barrier

Red light (around 630-660nm) is anti-inflammatory and supports cellular repair, which is why it is studied for wound healing and post-procedure recovery. For mild sunburn that has cooled, gentle red light may help calm redness and support the skin as it recovers.

Important: do not treat an active, hot burn

Never apply any warming or near-infrared device to skin that is still hot, blistered, or severely burned. Cool and hydrate the skin first, and wait until the acute heat has passed. If the burn blisters badly or covers a large area, see a doctor. Our safety guide covers when to avoid treatment.

Better use: everyday skin recovery

Where red light shines is ongoing skin repair and collagen support, not emergency burn care. For day-to-day skin health, see our skin guide.

For routine facial skin recovery and tone, a gentle LED mask is ideal. The AWA LX300 LED Face Mask ($199.99, FSA/HSA eligible) is a great fit. See how to use your FSA/HSA to save 30-40% with pre-tax dollars.

FAQ

Can I use red light on a fresh sunburn?

No. Wait until the skin has cooled and is no longer hot or blistered, then use gentle red light only.

Will it stop peeling?

It may support faster, healthier recovery, but cannot prevent peeling from a significant burn.
