Curcumin-mediated photodynamic therapy for mild to moderate Acne: A self-controlled split-face randomized study

Area of Science:

• Dermatology
• Photomedicine
• Biochemistry

Background:

• Acne vulgaris is a common skin condition affecting millions worldwide.
• Current treatments for mild to moderate acne have limitations and potential side effects.

Purpose of the Study:

• To evaluate the efficacy and safety of Curcumin-PDT for treating mild to moderate acne.
• To compare Curcumin-PDT with monotherapy blue light treatment.

Main Methods:

• A randomized split-face controlled study involving 11 patients with mild to moderate acne.
• One side of the face received Curcumin-PDT (1% curcumin mask followed by 445 nm LED light), while the other received only 445 nm LED light.
• Treatments were administered twice weekly for two weeks, with assessments conducted before and two weeks after treatment.

Main Results:

• Curcumin-PDT achieved a significantly higher total lesion clearance rate (54.7%) compared to monotherapy light (28.1%) (P=0.001).
• Clearance rates for inflammatory lesions were also significantly higher with Curcumin-PDT (59.3%) versus monotherapy light (36.5%) (P=0.013).
• Both treatments were well-tolerated, with mild erythema resolving within hours and transient pigmentation in two patients.

Conclusions:

• Curcumin-PDT is a safe and effective therapeutic option for mild to moderate acne.
• The study demonstrates the potential of Curcumin-PDT in improving acne vulgaris.
• Further research with larger cohorts may be warranted to confirm these findings.
