HYDRATE YOUR SKIN & HAIR
You might start seeing the word “squalane” on beauty products—but it’s not as strange as it may sound. It’s a lighter and more stable version of squalene, a lipid (or fat) that occurs naturally in human sebum and helps protect and moisturize skin, but that your skin produces less of as you age. Ethically sourced squalane comes from plant-derived sources like olives and rice and can be applied topically to replenish lost moisture and lock it in. “Traditionally used to treat wounds, squalane is now found in skincare products, since it’s effective at soothing, protecting, and hydrating skin,” explains Annie Chiu, M.D., a dermatologist in Los Angeles. “It also helps reduce fine lines and wrinkles and even scars.” In addition, squalane can help soften hair, boost shine, and shield it from external aggressors by sealing its cuticle (outer layer), Dr. Chiu says.
