The Clinical Efficacy and Statistical Evaluation of INTRAcel
TreatmentTakashi Takahashi, M.D.DermatologistTakahashi ClinicShibuya, Tokyo, Japan
Background:Minimally invasive Fractional Radiofrequency Microneedls(FRM) device is recently introduced. The device gives selective heating in the dermis using bipolar RF (or monopolar RF) through microneedles. This study is to demonstrate clinical improvement following FRM.
Methods:60 subjects with scar, facial laxity and large pore were enrolled. 60 patients were treated with a minimally-invasive FRM device (INTRAcel). Bipoloar RF energy was delivered through 49 micro-needle electrodes deployed into the reticular dermis from the papillary dermis vertically to the skin surface. Only subjects consenting to longitudinal follow-up during the study were enrolled to observe the improvement as time went by.
Results:As the result of 3 months follow-up, all patients did not have any problems during the period and any adverse events or complications weren’t observed. Patient satisfaction was high with 83.3%. Self-assessment of clinical outcome showed moderate to significant improvement in skin laxity, scar and pore.
Conclusion:Bipolar RF treatment makes deep dermal fractional heating in targeted deeper dermis. Clinical improvement by FRM treatment is related to collagen and elastin fiber which are generated by wound healing process.These results suggest Fractional Radiofrequency Microneedles treatment may become an important option for the treatment of facial skin laxity and scars.
INTRODUCTION
Previous generation ASR(Ablative Skin Resurfacing) laser devices were effective, but many of them could not avoid the problems of long down time and patient pain. On the contrary, NAR (Non-ablative Skin Rejuvenation) laser devices reduced pain and adverse effects, but these devices could not make dramatic effects. In the middle of 2000s, fractional technology opened new generation overcoming previous problems. But the fractional treatment was limitedly used because it could not control penetration depth and it gave damage on the epidermis.Recently introduced FRM opens new generation in aesthetic market by meeting the market demand. We observed wound healing process after the FRM treatment in the human body using histological and molecular biology technology. As the result, we found out the fact that FRM treatment induced a strong wound healing response drawing out collagen and elastin remodeling by Heat Shock Protein (HSPs) expression and various cytokines. Clinical improvement in skin laxity and acne scar is achieved by volume effects produced by neocollagenesis and neoelastogenesis.
STUDY DESIGN AND METHODSTUDY DESIGN
All subjects consented prior to participation. Patient consent for digital photography and adding the photos in article was also organized prior to treatment. Exclusion criteria consisted of history of injection with silicone, botox, filler, fat or a synthetic material placed in the intended treatment area, hypertrophic scar or bleeding disorder, lidocaine hypersensitivity, photosensitivity or anaphylaxis. Patients with a compromised immune system impaired wound healing, collagen vascular disease, implantable electronic device, or active infection were disqualified from participation. Only subjects consenting to longitudinal follow-up during the study were enrolled.
CLINICAL PROCEDURE
Patients were treated with a minimally-invasive FRM device. Bipolar RF energy was delivered through 49 micro-needle electrodes deployed into the reticular dermis vertically to the skin surface. The epidermis and superficial dermis were protected securely from RF heating at the insertion location by insulating the rest of each electrodes except its distal 0.3mm. Standardized photographs were taken at the baseline and at 3-month follow-up. Follow-up patients were asked to rate their overall satisfaction, the impression of scars and laxity improvement using a five-point scale.TREATMENT RESULTS60 subjects with mild to significant scar and rhytids were enrolled. All patients received one FRM full face treatment. All subjects were managed for 3 month follow-up. Mean age was 41.2 +/-23.5 years.All patients experienced transient edema and erythema, but it resolved within 48 hours. 13.3% of the patients experienced dry skin. However it was gone away within 2 weeks. Patient satisfaction was high with 1.6% dissatisfied, 15% neutral, 0% satisfied and 83.3% very satisfied (Fig 1). FRM treatment self assessment of clinical outcome showed significant improvement in acne scar and moderate to significant improvement in skin laxity.
CONCLUSIONFRM treatment has been shown to provide consistent and meaningful improvement in facial scar and laxity without complications and adverse effects. In this study, the average improvement seen following a single FRM treatment was approximately 93.3%. The result of this study may become an important option for scar and facial laxity treatment.

A high pressure RF emitted momentary on acne scar, burn scar, operation scar, traumatic scar and chapped skin regenerates skin.
Many people squeeze acne habitually to avoid it becoming a spot. However, fiddling with acne makes it inflamed and severe. What the worse thing is, patient can suffer from pain and pus come out of it. In this case, it takes long time to repair and could leave acne scar like craters on the moon If distressed woman from acne scar wears heavy make-up, it can make skin trouble even severe, therefore, applying ointment might be needed. But overused ointment can expand capillaries and make skin too sensitive to environments. Not only a scar but also a flush on face can disturb a daily life.
Skin often chaps easily on your shoulders, belly, thighs ,calves and even hips in case of gaining weight rapidly such as period of growth and pregnancy or applying steroid ointment on delicate skin for a long time. Once skin chaps, quick treatment will get good results.
Wrinkles are lines which form on a skin as dermis loose it’s collagen fiber. The appearances of the wrinkles are different slightly according to it’s location. Beside the small wrinkles which appear as aging, there are many wrinkles can appear on face and body because of gravity, folding a skin and making expressions. And each of them has it’s own treatment as per it’s cause and depth.
There are over 20 thousand pores on a face. Generally the diameter of a pore is approximately 0.02~0.05mm ,therefore, it’s difficult to see a pore for yourself. However, something like aging, change of seasons, woman’s menstrual cycle , pregnancy, stress can promote the production of sebum and then pores become as large as we can see. Many people have the misconception that a pore emits sweat but sweat comes out from sweat gland, through the skin. Large pores not only look dirty and oily but also can generate troubles on the skin by making it easy for gems to come in. In conclusion, the most important thing is to protect pores from expansion.
Whitening is not making skin to be white, but helping skin texture to be bright and transparent by making freckles and facial blemishes lightly and removing callus from epidermis.Interface controls the pigmentation of skin and effects on skin texture to be bright and clear.
Pigmentation means uneven condition of a skin texture like strains. Usually pigmentation is caused by freckles, acne scar, etc.
