British beauty company, Spectrala Ltd has launched an at-home skin tightening device, 21Skin London. Bringing professional results to your home, 21Skin London is a unipolar, radio frequency (RF) device for at-home use. 21Skin London works by generating heat energy to create new fibrous tissue and to stimulate the production of collagen, causing collagen fibres to become shorter and tenser. At the same time, the molecules that create collagen are left undamaged. 

21Skin London is now available to purchase from 21skin.co.uk, priced at £399. The brand has also launched DermaDeep Serum, priced at £25.
