Can Red Light Therapy Damage the Skin?

Red light therapy is generally considered safe for the skin when used properly. Unlike ultraviolet light, which can damage DNA and contribute to premature aging, therapeutic red light does not cause the same harmful effects.

The wavelengths used in red light therapy are designed to penetrate the skin without damaging surface cells. Instead, they stimulate cellular activity that may support collagen production and tissue repair.

In fact, red light therapy is commonly used in skincare treatments aimed at improving skin appearance.

Skin damage is unlikely unless the device is used improperly—for example, by exposing the skin for excessively long periods or using high-powered equipment incorrectly.

Following device guidelines helps prevent any potential irritation.
