The Guerlain Terracotta The Bronzing Powder (£39) launched in 1984, and ever since has been considered one of the best powder bronzers on the market — loved by makeup artists and beauty editors alike. This year, the brand introduces a new-and-improved formula that now uses 96% naturally-derived ingredients and includes few drops of argan oil sourced via the Targanine network of cooperatives located in Agadir, Morocco, which helps protect the local resources and works to create job opportunities in rural areas. Available in six shades, the formula is still just as silky and natural-looking as ever.
