Although bodies are 90% water, the other 10% is a squadron of evil sponges trying to pilfer aqueous reserves. Battle against dehydration with today’s Groupon: for $79, you get a HydraFacial with LED light therapy at Orange County Facial Cosmetics in Ladera Ranch (a $225 value).

At Orange County Facial Cosmetics, licensed aestheticians nourish skin with the HydraFacial—a combination of a microdermabrasion and intense moisturizers—which has been featured on television programs such as The Doctors. During what is also known as hydradermabrasion, skin techs wield a handheld mechanism with gentle suction that uproots impurities from pores, including makeup, blackheads, Lemonheads, and environmental pollutants. As it evicts unwelcome epidermal tenants, the mechanism simultaneously emits a serum that infuses water, vitamins, and antioxidants into the skin. The instrument’s spiral-shaped tip boasts many edges, allowing it to also exfoliate dry, dead cells from skin’s superficial layers in a noninvasive method that most clients find has no discomfort. The added illumination of an LED light-therapy treatment augments improvements in fine lines, enlarged pores, and pigmentation issues such as acne scarring or leftover face paint from a stint in clown school.
