If you haven't tried this brand before, the Herbivore Jewel Box Mini Facial Oil and Serum Set (£46) is a great place to start. It contains the new AHA/BHA exfoliating Prism Serum and the skin-regenerating Bakuchiol Serum, which is a natural retinol alternative. Plus, you get three oils: Emerald for calming and hydrating, Phoenix for deep nourishment and plumping up the skin, and Lapis for calming breakouts.
