A potent antioxidant, it protects against collagen breakdown from the environment and repairs sun-damaged skin. “Skin with fine lines and pigmentation from years of sun can benefit from ergothioneine,” Dr. Schweiger says.

The Ingredient: sea buckthorn oil (also known as seaberry oil)
Get the lowdown: Suffering from puffy, irritated skin after a night out with pals, or a frizzy mane that can’t be tamed? Meet your savior: sea buckthorn oil. An anti-inflammatory with antioxidant properties, this ingredient protects skin from harsh environmental effects like air pollution, soothes irritation, and smooths unruly locks. Those prone to breakouts, take caution: “The oil may clog pores and exacerbate acne,” Dr. Schweiger says.

The Ingredient: galactoarabinan (also known as GA)
Get the lowdown: Galactoarabinan might sound like the name of a planet in some far-off galaxy, but it’s actually a hot ingredient found in oodles of skincare products. GA “has been shown to decrease trans-epidermal water loss,” says Dr. Schweiger. Translation: It helps the skin to hold onto moisture, which results in plumper skin with fewer visible lines.
