Precautions for Red and Blue Light Therapy for Acne

Acne (comedones) is a common chronic inflammatory skin condition affecting the pilosebaceous units, particularly during adolescence. It frequently occurs on areas rich in sebaceous glands—such as the face, back, and chest—and is often accompanied by seborrhea (excessive sebum production). Following red light therapy for acne, direct sun exposure must be avoided to prevent post-inflammatory hyperpigmentation. Gently cleanse the face with lukewarm water and a mild facial cleanser several times daily to reduce skin oiliness. This helps minimize the accumulation of dust and other impurities on the skin surface, thereby effectively preventing follicular pore obstruction and secondary bacterial infection.

Additionally, avoid squeezing or picking at acne lesions with your fingers. Refrain from consuming high-fat and high-sugar foods, as well as fried foods, scallions, garlic, chili peppers, and other spicy or irritating foods. Instead, increase your intake of fruits and vegetables to help prevent constipation and indigestion—both of which may contribute to acne improvement.

Key considerations for red and blue light acne therapy include strict sun protection following treatment—minimize sun exposure whenever possible. If outdoor activities are unavoidable, apply appropriate sun protection measures. It is strongly recommended to undergo this procedure at a reputable, large-scale hospital under the care of an experienced dermatologist. We hope this article has been helpful.
