There's nothing like a warm bubble bath to relax and unwind at the end of the day and Holistic London's Relax and Sleep Bath Salts (£16) are packed with calming essential oils, as well as Epsom and pink Himalayan salts. Handmade in small batches in the brand's west London studio, pair it with their sustainably sourced all-natural candles (we recommend Neroli + Chamomile) for the ultimate pamper night in.
