Becca offers its fan-favourite powder highlighter in 15 shades on the Cult Beauty website, but it's the Becca Shimmering Skin Perfector in Champagne Pop (£30) that I suggest giving a go. Originally a limited-edition shade, the demand for the peachy-pink highlighter was so great (25,000 compacts sold in the first 20 minutes it became available on Sephora) that Becca eventually added it to the permanent collection.
The formula of the Shimmering Skin Perfectors is lovely — the powder is finely milled yet packed with pigment, while the shimmer particles are so small that they're practically undetectable. But Champagne Pop is extra special because of the colour: a peach powder with gold flecks, the shade contains both warm and cool tones (peach is a blend of yellow and pink), meaning it makes any skin tone it touches look absolutely radiant.
