Skin Care Tips: Lymphatic Drainage Massage for Quick Detox | VOGUE India

With the Diwali revelry just behind us and the wedding season on in full swing, it’s tough to not stray from our fitness regimens and avoid piling on those pounds. While nothing beats a good diet and exercise programme, a lymphatic drainage massage could prove to be a game changer for those looking for a quick detox. A huge trend in the West that is slowly gaining popularity here too, this massage helps to increase the supply of oxygen in your blood, improve circulation and increase lymphatic drainage—thereby reducing water retention, bloating and the appearance of cellulite, while also relaxing the muscles and helping you de-stress. Many skincare experts are now advising the use of Body Ballancer, a US FDA approved device, instead of a manual lymphatic massage which, to a large extent, depends on the service provider. “The Body Ballancer uses proven pressotherapy technology that works with the help of 24 individual air chambers per suit to ensure all your areas are taken care of. This is a much more advanced technique to ensure optimal lymphatic drainage and comfort,” says Mumbai-based dermatologist Dr Harshna Bijlani. The Ageless Clinic, which she heads, is one of the f...

Ultrahydrophobic 3D/2D fluoroarene bilayer-based water-resistant perovskite solar cells with efficiencies exceeding 22%

↵† Present address: Laboratory for Solar Energy & Fuels, University of British Columbia, V1V 1V7 Kelowna, BC, Canada. Preventing the degradation of metal perovskite solar cells (PSCs) by humid air poses a substantial challenge for their future deployment. We introduce here a two-dimensional (2D) A2PbI4 perovskite layer using pentafluorophenylethylammonium (FEA) as a fluoroarene cation inserted between the 3D light-harvesting perovskite film and the hole-transporting material (HTM). The perfluorinated benzene moiety confers an ultrahydrophobic character to the spacer layer, protecting the perovskite light-harvesting material from ambient moisture while mitigating ionic diffusion in the device. Unsealed 3D/2D PSCs retain 90% of their efficiency during photovoltaic operation for 1000 hours in humid air under simulated sunlight. Remarkably, the 2D layer also enhances interfacial hole extraction, suppressing nonradiative carrier recombination and enabling a power conversion efficiency (PCE) >22%, the highest reported for 3D/2D architectures. Our new approach provides water- and heat-resistant operationally stable PSCs with a record-level PCE. Perovskite solar cells (PSCs) hav...
