It comes as no surprise that with a name like H20, the brand’s flagship is decorated entirely in aqua and white. Beauty enthusiasts flock here for reasonably priced sea-derived skin- and body-care products, including Face Oasis ($34), an oil-free hydrating moisturizer. Shower gel costs $9; lotions in punchy scents like Tango Mango and Raspberry Guava will set you back $12.
