As the name suggests, the By Terry Hyaluronic Hydra Foundation (£49) formula contains hyaluronic acid, the molecule that our skin produces naturally to help retain moisture. That means this light-coverage formula (which can be layered to become nearly full-coverage), keeps skin feeling soft and looking fresh throughout the day (versus dry and cakey, which often happens around 3pm at the office). The dropper bottle resembles a serum, as does the formula itself, which is quite thin and is best applied with a brush. We absolutely love how radiant it makes our skin look, but were initially hesitant about the limited shade range. However, the brand promises to be release more hues in Summer 2020.
