The Product: Kiehl's super-hydrating Ultra Facial Cream is now featuring limited-edition labels designed by actor Zachary Quinto and Alanis Morissette—both of whom the brand calls "socially conscious influencers."

The Product:  Purchase one of Tarte's products formulated with their new t5 super fruit complex—like this cheek stain that creates a perfectly flushed look—and you're helping to support the Sustainable Amazon Partnership (SAP).

The Product: This pear-scented 3-in-1 is really a 4-in-1: it's a shampoo, shower gel, and bubble bath and it helps save the rainforest.

The Cause: Philosophy will donate 100 percent of net proceeds from the sale of Green to the Rainforest Foundation.

The Cause: Neutrogena Naturals supports the water conservation efforts of The Nature Conservancy, an organization dedicated to the global preservation of nature.
