Dry, uneven, and prone to undesirable growths. If your skin were a piece of real estate, it would be an abandoned lot. Book a facial at Urban Beauty Skin Care and watch your lot improve. Cosmetologist Sandy Tu has been honing her craft for six years at her unassuming Inner Sunset spot. Enter the cozy back room, lay your sorry self down, and enjoy a much-needed hour-long skin revamping. After assessing your pretty little face, Sandy will cleanse, exfoliate, steam, extract (upon request), and massage — for a mere $35. She then rubs a special serum into your skin and uses an ultrasound device to firm and soothe. The entire experience is topped off with a customized mask. Facial enthusiasts can opt for add-ons like the collagen mask for $10 — a pretty small investment. Considering how much it could raise the value of your property.
