Sequential facial skin rejuvenation with intense pulsed light and non-ablative fractionated laser resurfacing in fitzpatrick skin type II-IV patients: A prospective multicenter analysis.

ABSTRACT: BACKGROUND:While skin aging is triggered by multiple factors and typically presents with multiple manifestations, conventional treatment regimens deploy a single treatment modality. Typical approaches exploit ablative techniques, which involve considerable patient discomfort and downtime and can induce adverse events. Non-ablative fractionated laser (NAFL) resurfacing promotes neocollagenesis, with significantly fewer complications and discomfort. At the same time, intense pulsed light (IPL) therapies have a marked impact on skin tone, with an effect on collagen deposition. This study evaluated the combined effect of same-day, sequential IPL-NAFL treatment on photoaging of the face. DESIGN:In this prospective study, 30 patients presenting Fitzpatrick skin types II-IV, elastosis scores 3-6 and mild to moderate pigmentation, underwent three sessions, of full-face IPL therapy, followed immediately by NAFL treatment, conducted at 4-6 weeks intervals. Wrinkle/elastosis and skin qualities were scored at 1, 3, and 6 months after the last treatment session. Immediate responses were evaluated up to 30?min following treatment and adverse events were monitored throughout the study period. RESULTS:Wrinkle/elastosis scores gradually improved over the treatment period, with 59% of patients presenting a ?1-point improvement in FES scores by the 1-month follow-up session, which persisted also at the 6 months follow-up visit. Good to excellent pigmentation responses were recorded for ?63% and improvements in texture, brightness, and tightness were recorded for ?80% of patients throughout the follow-up period. Over 90% of the treated patients exhibited improved or much improved overall appearance. Patient scorings and satisfaction level reflected physician assessments. Treatments were well tolerated and the social downtime observed was of 1.5?±?0.25 days. CONCLUSION:The same-day combined IPL-NAFL regimen proved safe and elicited a significant skin rejuvenating effect, in a similar manner to that shown in other same-day combined therapies, without prolonging downtime of each individual modality.

Project description:Ablative fractional laser treatment is considered the gold standard for skin rejuvenation. In order to understand how fractional laser works to rejuvenate skin, we performed microarray profiling on skin biopsies to identify temporal and dose-response changes in gene expression following fractional laser treatment. The backs of 14 women were treated with ablative fractional laser (Fraxel®) and 4 mm punch biopsies were collected from an untreated site and at the treated sites 1, 3, 7, 14, 21 and 28 days after the single treatment. In addition, in order to understand the effect that multiple fractional laser treatments have on skin rejuvenation, several sites were treated sequentially with either 1, 2, 3, or 4 treatments (with 28 days between treatments) followed by the collection of 4 mm punch biopsies. RNA was extracted from the biopsies, analyzed using Affymetrix U219 chips and gene expression was compared between untreated and treated sites. We observed dramatic changes in gene expression as early as 1 day after fractional laser treatment with changes remaining elevated even after 1 month. Analysis of individual genes demonstrated significant and time related changes in inflammatory, epidermal, and dermal genes, with dermal genes linked to extracellular matrix formation changing at later time points following fractional laser treatment. When comparing the age-related changes in skin gene expression to those induced by fractional laser, it was observed that fractional laser treatment reverses many of the changes in the aging gene expression. Finally, multiple fractional laser treatments, which cover different regions of a treatment area, resulted in a sustained or increased dermal remodeling response, with many genes either differentially regulated or continuously upregulated, supporting previous observations that maximal skin rejuvenation requires multiple fractional laser treatments. In conclusion, fractional laser treatment of human skin activates a number of biological processes involved in wound healing and tissue regeneration.

Project description:ImportanceErosive pustular dermatosis (EPD) is a rare condition that typically affects actinically damaged skin of the scalp. Characterized by sterile pustules, erosions, and crusts, EPD is difficult to treat and heals slowly. The exact cause of EPD is unknown, although trauma is an inciting factor.ObjectiveTo describe 3 women who presented with prolonged facial erosions after cosmetic resurfacing procedures, specifically fully ablative carbon dioxide laser or medium-depth chemical peel.Design, setting, and participantsThis case series describes the clinical features, histopathological findings, laboratory results, and treatment of 3 patients with an ultimate diagnosis most consistent with facial EPD. Patients were evaluated between September 10, 2010, and May 6, 2016, in a dermatology clinic in an academic medical center. The patients were 3 women seeking diagnostic evaluation and therapeutic options for nonhealing facial erosions occurring after ablative procedures (carbon dioxide laser resurfacing or Jessner solution/trichloroacetic acid chemical peel).Main outcomes and measuresHistologic examination and wound culture from initial presentation as well as clinical follow-up documenting improvement with therapeutic interventions.ResultsAll 3 patients were women in their 50s or 60s for whom EPD was deemed to be the best diagnosis, after infection, immunobullous disorders, and other pustular dermatoses were considered. Histologic features were nonspecific. Treatment included a combination of topical and systemic therapies, such as corticosteroids, dapsone, isotretinoin, and/or antibiotics. Watchful waiting (tincture of time) appeared to be central to the healing process.Conclusions and relevanceAfter cosmetic resurfacing, patients may develop EPD isolated to the face. As a diagnosis of exclusion that should be considered in patients who have nonhealing wounds following ablative procedures, EPD is challenging to treat and may require the use of anti-inflammatory agents. Recognizing this condition is important, especially as cosmetic procedures become more widespread.

Project description:ImportanceThere remains little experimental evidence and no randomized clinical trial to date to confirm the benefit of platelet-rich plasma (PRP) for facial rejuvenation.ObjectiveTo investigate whether PRP injection improves the visual appearance, including texture and color, of photodamaged facial skin.Design, setting, and participantsIn this randomized clinical trial, participants and raters were masked to groupings. The setting was an academic-based, urban outpatient dermatology practice in Chicago, Illinois. Participants were adults aged 18 to 70 years with bilateral cheek rhytids of Glogau class II or greater. The duration of the study was August 21, 2012, to February 16, 2016.InterventionsEach participant received 3 mL intradermal injections of PRP to one cheek and sterile normal saline to the contralateral cheek.Main outcomes and measuresPrimary outcomes were photoaging scores (with subscores for fine lines, mottled pigmentation, roughness, and sallowness) as rated by 2 masked dermatologists. Secondary outcomes included participant self-assessment scores of improvement on a 5-point scale (worsening, no change, mild improvement, moderate improvement, or significant improvement), participant overall satisfaction scores on a 4-point scale (not satisfied, slightly satisfied, moderately satisfied, or very satisfied), and participant-reported or investigator-observed adverse events.ResultsOf 27 enrolled participants, 19 (mean [SD] age, 46.37 [10.88] years; 17 female) were analyzed. Reported adverse events, which were not associated with the study agent, included redness (n = 18), swelling (n = 16), bruising (n = 14), pruritus (n = 1), skin scaling (n = 1), and dryness of skin (n = 1). No participants reported any adverse events at 12 months. Mean (SD) photoaging scores rated by 2 dermatologists showed no significant difference between PRP and normal saline for fine lines (baseline, 1.00 [0.75] vs 1.05 [0.78]; 2 weeks, 0.95 [0.71] vs 0.95 [0.71]; 3 months, 0.95 [0.71] vs 0.95 [0.71]; 6 months, 0.95 [0.71] vs 0.95 [0.71]), mottled pigmentation (baseline, 1.21 [0.53] vs 1.21 [0.54]; 2 weeks, 1.16 [0.60] vs 1.16 [0.60]; 3 months, 1.00 [0.47] vs 1.11 [0.46]; 6 months, 1.16 [0.69] vs 1.16 [0.69]), skin roughness (baseline, 0.47 [0.61] vs 0.47 [0.61]; 2 weeks, 0.47 [0.61] vs 0.47 [0.61]; 3 months, 0.47 [0.61] vs 0.47 [0.61]; 6 months, 0.37 [0.60] vs 0.37 [0.68]), and skin sallowness (baseline, 1.11 [0.88] vs 1.11 [0.88]; 2 weeks, 0.95 [0.85] vs 0.95 [0.85]; 3 months, 0.58 [0.61] vs 0.58 [0.61]; 6 months, 0.37 [0.68] vs 0.37 [0.68]). At 6 months after a single treatment, participants rated the PRP-treated side as significantly more improved compared with normal saline for texture (mean [SD] self-assessment score, 2.00 [1.20] vs 1.21 [0.54]; P = .02) and wrinkles (mean [SD] self-assessment score, 1.74 [0.99] vs 1.21 [0.54]; P = .03).Conclusions and relevanceMasked participants noted that both fine and coarse texture improved significantly more with a single treatment of PRP than with normal saline. Both participants and raters found PRP to be nominally but not significantly superior to normal saline.Trial registrationClinicalTrials.gov Identifier: NCT01372566.
