superficial RF treatment option has 6000 pulses, and improves skin tone and reduces wrinkles through mild fractional RF resurfacing. It is useful for treating the upper and lower eyelids and in combination treatments for wrinkles in the periorbital, perioral and neck areas. It can also used as an individual treatment mode.


Acne and acne scar treatment INTRAcel FRM-bipolar and monopolar modes can be used for the treatment of mild acne. As most of the sebaceous glands can be found at a 1 mm depth, the treatment depth of 0.8–1.5 mm will result in decreased sebum production and the tightening of enlarged pores. The heat may also reduce the growth of bacteria. The treatment is performed on a monthly basis for between three and five treatment sessions. The improvement in skin condition can usually be seen from the second treatment session. INTRAcel has been widely used for acne treatment in Asian countries; however, the European experience for this indication is still limited and requires further study. In acne scars, both FRM-bipolar and


FRM-monopolar, as well as superficial RF, can be used. The final clinical result will be visible within 3 months. In the study conducted by Cho et al6


,


bipolar FRM resulted in improvement of acne scars in 22 patients, and a reduction of large pores in 21 out of 30 patients7


. The patient satisfaction profile


was favourable, with 26 patients being very satisfied or satisfied with the treatment results. The mean duration of erythema was 7.8 days and mild folliculitis was observed in two patients. With regular topical anaesthesia, with 5% Emla cream, the pain was mostly mild (n=18; 60%), but severe in two patients (n=6; 7%) and moderate in four patients (n=13; 3%). It is possible that the discomfort can effect compliance to serial treatments9


. INTRAcel is effective for a variety of types of acne scars.


The author has seen clear improvements — even with the most difficult ice-pick scars.


Results In Asian countries, the INTRAcel has been available since 2009, and in Europe since 2011. In the author’s clinic, treatments using this device began in April 2011 and over 800 treatments have been performed to date. The main indications for the treatment have been rejuvenation and acne scars. In addition of the tightening effect, the lifting effect of the sagging skin of the face and neck is remarkable. The author has treated a range of patients including


cases of tightening the upper arms, elbows, and knees, and treating stretch marks and other scars on the body — all of which have reaped good results. The INTRAcel treatment also reduces telangiectasia, but is not the treatment of choice for this indication. INTRAcel is effective for a variety of types of acne


scars. The author has seen clear improvements — even with the most difficult ice-pick scars. It can also be used safely for patients who have undergone previous ablative laser resurfacing treatments. Indeed, the author’s personal experience with


INTRAcel treatment in mild acne is encouraging — sebum secretion is diminished and inflammation decreased. However, in moderately inflamed acne the sebum secretion can be increased for a short period after the first treatment, resulting in a transient worsening of acne and requiring supportive topical treatment or oral medication. Good treatment response can be achieved by combining topical treatments and LED therapy. At present, the INTRAcel treatment option for acne remains for cases unresponsive to common treatment strategies. Severe acne should first be treated with oral medication. In skin rejuvenation there is an immediate treatment


effect followed by a gradual improvement over 4–8weeks. In facial rejuvenation, the full face, including eyelids and neck, can be treated in the same session.
