Low-level LED therapy: what to know

LED devices deliver visible or near-infrared light to the skin without the heat used by many lasers. Blue light may target acne-related bacteria, while red or near-infrared light is used in plans aimed at inflammation or repair. A session does not remove a lesion or clear every cause of pimples. The device, wavelength, dose, eye protection, and treatment schedule all affect the experience. Home panels are not interchangeable with professionally supervised treatment.

A clinician can decide whether LED Light Therapy fits your skin concern and check medicines or conditions that increase light sensitivity. Follow the device instructions, protect the eyes as directed, and keep the skin routine gentle. Tell the clinician about photosensitising medicines, eye disease, seizure-related light sensitivity, or a history of unusual reactions to light. Results are usually assessed over a planned course rather than after one exposure, and maintenance may be discussed.

Arrange an assessment for painful, deep, scarring, or rapidly worsening acne, or for a changing spot mistaken for a pimple. Stop treatment and seek advice for blistering, marked swelling, persistent pain, vision symptoms, or a new rash after exposure. LED should not delay evaluation of infection or another diagnosis.

Ask which wavelength is intended for your concern, whether your medicines affect light sensitivity, how often to use the device, and how progress will be measured.
