Summer Meal comes shortly after the launch of Yse, which Sims launched in partnership with SOS Beauty earlier this year. This brand targets melasma and hyperpigmentation with clinically backed formulations.

Saie, which hired its first president last year, has distribution with Sephora, funding from Unilever Ventures and Goop founder Gwyneth Paltrow, and an assortment of skincare-makeup hybrids.
