My teenaged daughter gave me the best holiday gift last year. In a small recycled jar, she’d mixed together sea salt, grapeseed oil and mint essential oils into a natural skin scrub. This heavenly blend not only turned my shower into a spa, it transformed my skin: When I scrubbed it on and then let the oil soak in before toweling off, my cracked and chapped winter skin was suddenly soft, smooth and hydrated. With this miracle in mind, I discovered a natural skin scrub recipe that’s easy to make in minutes.
