Abstract
Inflammatory skin diseases, such as rosacea and acne, are major causes of facial erythema and accompanying skin barrier dysfunction. Several methods to restore the impaired skin barrier and improve facial erythema, such as medication, radiofrequency, laser, and ultrasound therapy were attempted. This study evaluated the efficacy and safety of dual-frequency ultrasound with impulse mode, for improving skin hydration and erythema in Asian subjects with rosacea and acne. Twenty-six subjects with facial erythema received an ultrasound treatment once per week, for 4 weeks, over both cheeks. The erythema index and transepidermal water loss (TEWL) were measured at each visit. Clinicians assessed the erythema improvement and patients evaluated their satisfaction level. The average decrease in TEWL and erythema index at 6 weeks was 5.37 ± 13.22 g·h−1·m−2 (p = 0.020) and 39.73 ± 44.21 (p = 0.010), respectively. The clinician’s erythema assessment and the subject satisfaction questionnaire score significantly improved at final follow-up (p < 0.001; p = 0.003, respectively). No serious adverse effects were observed during the treatment and follow-up periods. The dual-frequency ultrasound with impulse mode appears to be effective and safe for improving skin hydration and erythema in patients with rosacea and acne.
Highlights
Facial erythema is caused by a variety of factors that induce cutaneous blood vessel dilatation and increase the blood flow to the skin
Persistent facial erythema was found in 87% of patients with rosacea [1] and 66% of patients with acne treated with isotretinoin [2]
Men and women aged over 18 years with facial erythema related with rosacea and acne were included in this study
Summary
Facial erythema is caused by a variety of factors that induce cutaneous blood vessel dilatation and increase the blood flow to the skin. Primary skin diseases, such as rosacea and acne, are representative inflammatory skin conditions that cause facial erythema. A recent ultrasound device called SONO STYLER (WEYERGANS® , Dueren, Germany) is differentiated from conventional ultrasound devices, in that, it utilizes a specialized impulse mode with a constant wave period. This regular interval energy transfer enables a more accurate energy delivery, intensifying it over the targeted tissue, without unnecessary thermal damage. The present study evaluated the efficacy and safety of an impulse mode dual-frequency ultrasound
