However, poor compliance caused by adverse events and antibiotic resistance is a major cause of treatment failure.<\/jats:p><\/jats:sec><jats:sec><jats:title>Aims<\/jats:title><jats:p>To determine the effectiveness of photodynamic therapy (PDT) with intense pulsed light (IPL) in the treatment of acne when combined with a cream containing licochalcone A, L\u2010carnitine and decanediol (so\u2010called, \u2018active formulation\u2019) versus PDT alone.<\/jats:p><\/jats:sec><jats:sec><jats:title>Patients\/Methods<\/jats:title><jats:p>Twenty\u2010nine volunteers, aged 21\u201039 years (26 women and 3 men, mean age 29.41 \u00b1 5.24 years), with mild to severe facial acne, were enrolled.

Reduction in acne quantity, melanin index and erythema index were assessed 2 weeks after the second treatment (day 28), 1 week after the fourth treatment (day 49), and 1 month after the fourth treatment (day 70).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Compared to baseline, patients in the active formulation group demonstrated a faster onset of reduction in the number of lesions at 2 weeks after the second treatment (p=0.010 for inflammatory acne and p=0.001 for non\u2010inflammatory acne). A significantly greater reduction in lesion count was observed in the active formulation group compared with the vehicle group at all timepoints of evaluation for noninflammatory acne (day 28, day 49, and day 70; p=0.003, 0.005 and 0.002 respectively), and at 1 month after the fourth treatment for inflammatory acne (p=0.036).

Significant acne reduction and improvements in post\u2010inflammatory hyperpigmentation were observed, which offers acne patients a better therapeutic option.
