Plus, Tracee Ellis Ross' scarlet lip, Sofia Richie's middle part and 7 other beauty looks we loved on Instagram this week.

Summer beauty is still alive and well, as proved by the leading ladies of Instagram this week. Kourtney Kardashian sent the internet into a flurry when she uploaded a shot of herself getting off a jet ski, thigh muscles looking strong and taut. Sofia Richie paired her oversized sunnies with a middle part slicked back into a bun, while Winnie Harlow let her curls loose. Bella Hadid proved that even supermodels get sunburned, posting a rosy photo of herself in Greece. Perhaps she will take a page out of Dua Lipa's book and give her summer skin a little TLC, with a soothing, moisturizing face mask. Make like these ten beauties this long weekend and embrace summer skin, hair and attitude while you still can.
