tier1 Therapeutic efficacy of metronidazole by needle-free jet injection combined with blue light therapy in Moderate-to-Severe facial acne vulgaris.
Abstract summary (English) BACKGROUND: Acne vulgaris is one of the most common dermatological diseases. Some topical treatments for acne used in combination, such as blue light and topical antibiotics (such as metronidazole) by needle-free jet injection (NFJI), are becoming prevalent in clinical practice, but the efficacy remains uncertain. METHODS: In order to investigate the effect of blue light combined with metronidazole by NFJI in the...

View on PubMedtier1 Efficacy and safety of low-level light therapy by delicate pulsed light combined with low-dose oral isotretinoin for the treatment of acne vulgaris: a randomized split-face study.
Abstract summary (English) Acne vulgaris (AV) is a common dermatosis that causes psychological problems. Isotretinoin is the first-line treatment for moderate-to-severe AV, but its onset of effect is delayed. Although light-based therapy is widely used in the treatment of AV, there is a lack of reports on delicate pulsed light (DPL) which has a narrow therapeutic spectrum (500-600 nm).

Abstract summary (English) BACKGROUND: Photodynamic therapy had made great progress in the treatment of acne vulgaris. However, there is no meta-analysis on the effectiveness and safety of red light therapy for acne vulgaris. OBJECTIVE: To assess the efficiency and safety of red light therapy for acne vulgaris.

Abstract summary (English) Acne is a dermatosis that affects almost 90% of the adolescent population worldwide and its treatment is performed with retinoids, antimicrobials, acids, and topical or systemic antibiotics. Side effects such as skin irritation in addition to microbial resistance to antibiotics are the main side effects found. Phototherapy with blue light is being used as an alternative treatment.

View on PubMedtier1 A Comparative Study Between Once-Weekly and Alternating Twice-Weekly Regimen Using Blue (470 nm) and Red (640 nm) Light Combination LED Phototherapy for Moderate-to-Severe Acne Vulgaris.
Abstract summary (English) BACKGROUND AND OBJECTIVE: Phototherapy for acne with a combination of blue and red light-emitting diodes (LEDs) appears to have excellent potential in treating inflammatory acne. However, a standard twice-weekly protocol administered 3 days apart may not be practical for patients. This study aims to seek the efficacy of LED treatment in moderate to severe acne, comparing between once and alternating twice-weekly...

View on PubMedtier1 A randomized controlled study for the treatment of acne vulgaris using high-intensity 414 nm solid state diode arrays.
Abstract summary (English) The treatment of acne vulgaris poses a challenge to the dermatologist, and the disease causes emotional anxiety for the patient. The treatment of acne vulgaris may be well-suited to home-use applications, where sufferers may be too embarrassed to seek medical treatment. This randomized controlled study is designed to quantify the effectiveness of using a blue light device in a therapy combined with proprietary...

View on PubMedtier1 Randomized trial of three phototherapy methods for the treatment of acne vulgaris in Chinese patients.
Abstract summary (English) BACKGROUND AND AIMS: Acne vulgaris is common in Asian populations. We compared three methods of phototherapy for the treatment of moderate to severe facial acne vulgaris in Chinese patients. METHODS: Patients were randomly assigned to receive photodynamic therapy (PDT), intense pulsed light (IPL) or blue-red light-emitting diode (LED) phototherapy to the right side of the face until the inflammatory lesion count...

View on PubMedtier1 The clinical and histological effect of home-use, combination blue-red LED phototherapy for mild-to-moderate acne vulgaris in Korean patients: a double-blind, randomized controlled trial.
Abstract summary (English) BACKGROUND: Blue and red light have been reported to have beneficial effects on acne. However, there has been no double-blind, randomized study of acne treatment for combined blue and red light-emitting diode (LED) devices, and the associated molecular mechanisms have rarely been investigated. OBJECTIVES: To evaluate the efficacy, safety and histological changes of combined blue and red LED phototherapy for acne...

View on PubMedtier1 Clinical efficacy of home-use blue-light therapy for mild-to moderate acne.
Abstract summary (English) INTRODUCTION: Blue-light light-emitting diode (LED) therapy has become widely used for the treatment of inflammatory acne. In this study we evaluated the efficacy of a home use blue-light LED application in improving lesions and shortening their time to clearance. METHODS: This was an IRB approved randomized self-control study.
