Overview — What LED light therapy does?

LED (light-emitting diode) therapy delivers narrow-band light wavelengths to the skin to reduce inflammation, combat acne bacteria, and stimulate collagen. Red and near-infrared wavelengths are most commonly used for anti-aging and wound healing; blue light targets acne-causing bacteria (P. acnes). LED is painless, non-ablative, and appropriate as a stand-alone therapy or complementary treatment between more aggressive procedures.

How it works? (science, simply)

Different wavelengths penetrate to different depths and interact with skin cells and chromophores. Red light (~630–660 nm) can stimulate mitochondria in skin cells to boost collagen synthesis and reduce inflammation; near-infrared penetrates deeper and supports tissue repair. Blue light (~415 nm) can rupture the cell walls of acne-causing bacteria, reducing active breakouts. Treatment dosing and consistency determine outcomes.

Ideal uses & limitations

• Acne reduction and maintenance therapy.
• Mild to moderate photoaging and inflammation reduction.
• Safe for nearly all skin types, though results require repeated sessions and are more subtle than lasers.

Treatment schedule & sensation

Sessions are typically 10–30 minutes; many providers recommend weekly sessions for an initial course followed by maintenance every 2–4 weeks. The treatment is warm and soothing with no downtime.

Benefits

• Painless, calming therapy with no recovery time.
• Complements other procedures (HydraFacial, microneedling) to speed healing and improve results.
• Useful for ongoing acne management and skin maintenance.
