    Abstract Introduction: Seborrheic dermatitis (SD) is a chronic, relapsing, inflammatory disorder of the head and trunk.
    Objectives: To explore the potential of a 1% Selenium disulphide (SeS2)-based shampoo to prevent relapses of scalp SD (SSD) following corticosteroid/salicylic acid (TCS/SA) treatment.
    Materials & methods: After a 2-week treatment with TCS/SA, adult patients with moderate-to-severe SSD received either the SeS2-based shampoo or its vehicle for eight weeks in a randomized, double-blinded fashion. Visits took place at baseline, weeks 2, 6 and 10. SSD severity was assessed based on erythema, flakes and pruritus; patients assessed the severity of pruritus. Global investigator and patient satisfaction were assessed at week 10.
    Results: Forty-eight adults were included. After four and eight weeks of post TCS/SA maintenance regimen, 8.1% and 16.7% in the SeS2, and 41.7% and 54.2% in the vehicle group relapsed, respectively. First median time-to-relapse in the vehicle group was 56 days; this was not reached for SeS2. After two weeks of TCS/SA, the prevalence of patients with no pruritus was 29.2% in the SeS2 group, and 41.7% in the vehicle group; it increased to 76.2% with SeS2 and to 57.1% with the vehicle at the end of the study. The clinical benefit of treatment with TCS/SCA was maintained in the SeS2 group only. Investigators and patients were highly satisfied with the efficacy of SeS2. Tolerance to SeS2 was excellent, with no reported adverse events.
    Conclusion: The SeS2-based shampoo significantly reduces the time-to-relapse of moderate-to-severe SSD flares. Its tolerance was excellent, with no reported adverse events.

    Abstract Introduction: Acne vulgaris (acne) is characterized by both inflammatory and non-inflammatory lesions. Benzoyl peroxide (BPO) 5% is approved to treat acne but may cause skin irritation and/or contact allergy.
    Objectives: To compare the benefit in acne of a multitargeted dermocosmetic cream containing salicylic acid, lipohydroxy acid, niacinamide, 2-oleamido-1,3-octadecanediol, piroctone olamine, zinc, Aqua posae filiformis, and thermal spring water (DC-Eff) to BPO 5% gel.
    Materials and methods: 150 Caucasian subjects (50% female) aged between 18 and 40 years, with mild to moderate acne according to the GEA (Global Evaluation of Acne) grading system were randomized into two parallel groups (DC-Eff or BPO to be applied twice daily for 56 days). IGA (investigator global assessment), GEA, lesion count, clinical signs and symptoms, and subject assessment were evaluated at baseline, and after 28 and 56 days (D28 and D56) of treatment.
    Results: The responder analyses of the IGA and GEA scores showed that 62.2% and 47.3%, respectively, in the DC-Eff, compared with 50.0% and 36.5%, respectively, in the BPO, had improved by at least one point at D56. Inflammatory, non-inflammatory, and total lesion counts significantly (p < 0.0001) decreased with both products from baseline, with no between-group difference. Subjects considered that their skin was smoother and that DC-Eff was easy to apply. DC-Eff was better tolerated than BPO.
    Conclusions: DC-Eff applied twice daily is as beneficial as BPO in improving mild-to-moderate acne. DC-Eff was better tolerated than BPO and highly appreciated.

    Abstract Background and objectives: Low-level light therapies using visible to infrared light are known to activate several cellular functions, such as adenosine triphosphate and nitric oxide synthesis. However, few clinical observations report its biological consequences for skin and scalp homeostasis. Since scalp inflammation was recognized as a potential physiological obstacle to the efficacy of the reference hair regrowth drug Minoxidil in vivo and since perifollicular inflammation is the hallmark of about 50%-70% follicular units in androgenetic alopecia, we decided to investigate whether the anti-inflammatory activity of LLLT/GentleWaves® device were assigned to L'Oréal by Light BioScience L.L.C., Virginia Beach, VA (US) could enhance hair regrowth activity of Minoxidil.
    Study design/materials and methods: We conducted a first experimental clinical study on 64 men with androgenetic alopecia using LLLT/GentleWaves®, 590-nm predominant wavelength 70 seconds, specifically pulsed once per day, for 3 days, and we performed a whole-genome analysis of treated scalp biopsies. In a second clinical study, including 135 alopecic volunteers, we evaluated the hair regrowth activity in response to the upgraded LLLT/GentleWaves® device and Minoxidil.
    Results: In the first clinical study, whole-genome analysis of treated scalp biopsies showed downregulation of scalp inflammatory biomarkers, such as AP1/FOSB messenger RNA (mRNA) and mir21, together with the disappearance of CD69 mRNA, specific to scalp-infiltrating T cells of about 50% of the studied volunteers prior to the LLLT/GentleWaves® treatment. In the second clinical study, we observed that LLLT/GentleWaves® was able to boost the hair regrowth activity of a Minoxidil 2% lotion to the extent of the highest concentration (5%) in terms of efficacy, number of responders, and perceived performance.
    Conclusions: Altogether, these observations suggest the potential benefit of LLLT/GentleWaves® as a noninvasive adjunctive technology for skin and scalp conditions, where a mild perifollicular inflammation is involved. Lasers Surg. Med. 2021. Copyright © 2021 Wiley Periodicals LLC.

    Abstract Introduction: A monocentre double-blind two parallel group clinical study was conducted to assess whether a new skincare regimen containing retinol, adenosine and hyaluronic acid, applied after the injection of botulinum toxin A to the glabellar area, provided a beneficial effect.
    Material and methods: Standardised photographs acquired using LifeViz cameras and zoomed pictures of the glabella and of the crow's feet areas were analysed with automatic well-defined procedures. Perceived efficacy and tolerance were also analysed by comparison between the two groups.
    Results: A beneficial effect versus placebo-treated group was proven in the group having topically applied the new skincare regimen for 2 months following botulinum toxin A injection with no touch up after 1 month. 3D image analysis showed more rapid results on D10 and enhanced efficacy on M2. Moreover, a beneficial effect independent of injection was measured in the crow's feet area, and analysis of the self-evaluation questionnaire showed enhanced efficacy perceived by the volunteers.
    Conclusion: A specially developed skincare regimen applied immediately after botulinum toxin A injection completes the beneficial effect of the injection on the glabellar area and offers clinical benefits in fine lines, wrinkles and smoothness on the whole face.
