Introduction
The severity of acne varies among patients, and thus the cost of red-light therapy for acne also differs. During acne treatment, many patients are eager to recover quickly and regain their health, leading to psychological impatience. Each session of red-blue light therapy for acne typically lasts about 30 minutes. During treatment, red and blue light are applied separately—or alternatively, focused irradiation may be used. For red-light therapy, it is essential to strictly follow the physician’s instructions and adhere to the prescribed treatment protocol.

How Long Do the Effects of Red-Blue Light Therapy for Acne Last?
The efficacy of red light therapy for acne is often long-lasting—potentially permanent—provided appropriate skin care is maintained to prevent acne recurrence. Red light exerts antibacterial and anti-inflammatory effects; consequently, inflammatory acne lesions such as pimples and papules gradually resolve. After completing red-blue light therapy, meticulous skin cleansing and care are essential: gently wipe the skin with normal saline, followed by thorough facial cleansing each night before bedtime.
A typical course of red-blue light therapy for acne consists of approximately five sessions; however, treatment duration and cost may vary depending on individual disease severity. Each red light session lasts about 30 minutes, though exact timing may vary per patient. For optimal safety and efficacy, patients should seek treatment at reputable local hospitals. Red-blue light therapy improves and repairs skin health: blue light specifically targets and eliminates *P. acnes*, while red light reduces inflammation. Importantly, blue light contains no ultraviolet radiation and is non-irritating to the skin, making it suitable for patients with mild-to-moderate acne.Given variations in acne severity among individuals, red light therapy costs also differ. During treatment, many patients experience significant psychological stress and impatience, driven by their strong desire for rapid recovery and restored skin health.
Each red-blue light therapy session for acne typically lasts about 30 minutes. During treatment, red and blue light are administered either sequentially or simultaneously. Patients undergoing red light therapy should strictly adhere to their physician’s instructions and prescribed treatment protocols. While undergoing therapy, acne patients should avoid using cosmetics to prevent post-inflammatory hyperpigmentation and minimize potential skin damage.
