Herbar The Face Oil (£37)
"In the winter months, I'm all about adding extra hydration into my skin-care routine. Herbar's Face Oil has been a lifesaver when it comes to fighting off dry patches, especially around my nose. It's formulated with a calming mushroom blend that soothes my skin in minutes. I love applying it at night before bed and doing a facial massage with the brand's Gua-Shroom, a mushroom-shaped gua sha tool." — RR
