R.Abu-Eittah, M., Fractional Radio Frequency for Acne Scar Treatment, , 2014.


Acne is a common skin condition specially in adult age group. Its course varies according to its severity, mishandling and management. Acne scars are quite common and lead to disfigurement and psychosocial problems. Acne scars are dermal deprasion commonly caused by the destruction of collagen. Various procedures like chemical peeling, dermabrasion, punch excision, fillers and laser resurfacing have been used with varying degrees of succees.
Acne scars are classified as rolling, ice-pick, shallow boxcar and deep boxcar. Rolling scars appear like hills and valleys without sharp borders. Ice-pick scars also known as pitted scars appear as round deep depreasions. Boxcar scars have flat-u-shaped base, broader than ice-pick scars they are round or linear at the skin surface. Shallow boxcar scars terminat in the mid-dermis, and deep boxcar scars penetrate to the reticular dermis.
Ablative laser therapies with CO2 fractional laser and Er:YAG lasers are well accepted treatment for post acne scars for creation of a controlled thermal injury to the dermis with subsequent neocollagenesis and remodeling of scarred skin.
In this study we examined the efficacy and safety of ablative CO2 fractional laser(10,600nm) in twenty patients with mild and moderate acne scars.
Patients and methods
Twenty patients(14females and 6males) with age ranging from18 years to30 years, skin type III and IV with mild to moderate acne scars ,they were treated at skin clinic in laser institute of cairo university.
Treatment with ablative CO2 fractional laser of 10,600nm wavelength. The laser fluence was delivered with settings of 20 to 40 mJ /cm2 , density level 3 using the deep resurfacing mode. Those who have any procedures such as chemical peeling , dermabrasion or retinoids treatment before they were excluded.
Patients were informed about the procedure as complications and outcomes.A written consent was taken and photographs before and after each laser sitting. Topical anesthetics were used , superficial cooling after laser sitting by chilled air. Every patient was treated for six sittings each every month apart.
