Most users notice bright red light and may feel mild warmth. A session should not feel painful or produce a burning sensation. Afterward, temporary warmth or mild redness may occur, but a strong or lasting reaction should not be dismissed as proof that the treatment is working. Wash or moisturize your skin only as appropriate for your normal routine and according to your provider’s advice.
Do not judge the result from one appointment. Light-based treatments are often evaluated over a series of properly controlled sessions, and outcomes depend on the purpose of the treatment. A red light therapy bed designed for general wellness is not automatically validated for a medical condition, and a marketing claim is not the same as a clinical endpoint.
Record changes objectively. 例えば, note the date, settings, body area, symptom score, and photographs taken under similar lighting if appearance is the goal. This makes it easier to separate a real trend from normal daily variation and gives a clinician useful information if a reaction occurs.
