ABSTRACT: SUMMARY BACKGROUND: Many over the counter topical products claim to reverse the signs of cutaneous photo-damage. To date, the two most studied ingredients for improving the texture, tone, and pigmentation of the skin are topical retinoids and hydroquinone.1
OBJECTIVE: This split face study compares a mass market skincare regimen with a prescription skin care regimen for improvement in photo damaged skin.
METHODS: Twenty-seven subjects with moderate photo damaged facial skin were enrolled. Each subject was consented and assigned with the mass market anti-aging system (Treatment A) to one side of the face and the prescription anti-aging system (Treatment B or Treatment C) to the other side of the face. Treatment B contained 13 subjects whom did not use 0.025% Retinol cream. Treatment C contained 14 subjects who used a 0.025% Retinol Cream. Subjects had 4 visits over 12 weeks for digital photography and surveys. Photographs were evaluated by blinded physicians.
RESULTS: Physician objective analysis showed all three systems to have a statistically significant clinical improvement in photoaged skin seen in as little as 4 weeks of use. Participant’s surveys rated the mass market system higher than both of the professional systems for visible skin changes, ease of use, and likelihood to recommend to a friend. Twelve of twenty-seven subjects preferred the mass market system for overall improvement while twelve thought each system gave the same improvement.
CONCLUSION: This study demonstrates that a mass marketed skin care system can give similar clinical improvements in photo-aged skin as a professionally dispensed prescription system and the majority of participants preferred the mass-marketed system.

ABSTRACT: BACKGROUND: Noninvasive antiaging neck and décolletage treatments are highly sought after by aging patients. A topical cosmetic antiaging cream was formulated with skin matrix building and smoothing ingredients to help reverse visible signs of aging on the neck and décolletage, including laxity, crepiness, deep lines, and hyperpigmentation.
OBJECTIVE: A clinical study was conducted to evaluate the efficacy and safety of the antiaging neck/décolletage cream over a 16-week treatment period.
METHOD: Caucasian women with moderate texture (including wrinkles, fine lines, laxity, and/or crepiness) on the neck and hyperpigmentation on the décolletage used the test cream for 16 weeks. At weeks 0, 8, 12 and 16, the dermatologist investigator graded neck texture, décolletage texture and décolletage pigmentation using a 0-5 scale, and irritation/tolerability using a 0-4 scale. Subjects were photographed and provided self-assessment of their aging parameters as well as product tolerability. Chromameter measurements were collected in triplicate on the chest at weeks 0, 8, and 16 to quantitatively and objectively assess pigmentation.
RESULTS: Forty-two women completed the study. All dermatologist-graded aging parameters were significantly improved at each time point, P<0.001. Chromameter measurements demonstrated significant improvements in brightness (L*) and redness (a*), P<0.05. Self-assessed aging parameters were significantly improved on the décolletage and neck, P<0.05. Digital photography demonstrated obvious antiaging effects including improved texture of neck and décolletage areas, reduced appearance of lines and wrinkles, reduced mottled hyperpigmentation, and a more youthful, firm appearance. The test cream was well-tolerated with no significant changes in irritation parameters throughout the study.
CONCLUSION: The antiaging neck/décolletage cream delivered significant firming and smoothing effects with reduced appearance of hyperpigmentation and can be considered an effective topical homecare treatment option for patients seeking rejuvenation of this challenging area.

ABSTRACT: BACKGROUND: Radiofrequency has long been successfully employed for medical and, more recently, aesthetic indications due to its ability to cause tissue contraction by thermal induction of neocollagenesis and the subsequent wound healing cascade, leading to collagen
remodeling and a tightening effect. Percutaneous RF treatment provides therapeutically relevant thermal stimulation directly to the tissue target in a minimally invasive manner, which is therapeutically ideal because of limitations inherent in transcutaneous RF heating. A novel device combines percutaneous RF with thermistor-controlled temperature regulation and external tissue temperature monitoring, providing the ability to safely deliver RF energy.
METHODS: Percutaneous subdermal RF treatment was performed on 48 samples of abdominoplasty tissue; samples were marked to standardize measurement of surface area in the treatment zones, and a subdermal temperature target of 51°C was preprogrammed into the treatment device. The treatment cannula was inserted parallel to the dermal plane at four points with a single pass per insertion.
Surface area was then re-measured.
RESULTS: Approximate average reduction in surface area was 91.23±19.33 mm2, ranging between 124.45 mm2 and 35.39 mm2 (median 96.83 mm2). Results were statistically significant (P<0.0001). Statistical analysis via analysis of variance (ANOVA) plus Tukey post-hoc testing revealed no statistically significant difference between the sides in all comparisons, demonstrating symmetry in contracture.
CONCLUSION: Percutaneous subdermal monopolar RF creates dramatic, immediate tissue contraction in vitro and is a viable technology for tissue tightening.
