SD Beauty Bar in Chula Vista's Third Avenue Village is a Latina-owned and women-owned esthetician studio and lash-supply retailer at 651 Third Avenue, Suite D, combining appointment-based lash extensions with an e-commerce product line for licensed lash technicians. The retail inventory spans premade lash fans, isolation tweezers, cyanoacrylate adhesives, custom-curl trays, and decorative lash tiles—the same caliber of application tools stocked by volume-lash specialists at Vbrow Lash Wax Studio across the Chula Vista market. In-studio lash appointments run alongside the Shopify-powered storefront, allowing walk-in clients to purchase supplies while appointment-only extension sessions proceed in the treatment space. The Third Avenue location sits in the walkable downtown Chula Vista retail strip shared by independent boutiques such as DVIA Art and Style, giving the beauty bar foot traffic from the surrounding dining and shopping corridor anchored by Savoie and Filippi's Pizza Grotto. Lash-tray inventory includes 0.03-millimeter and 0.05-millimeter diameter fans in C-curl, D-curl, and proprietary custom-curl configurations, with brown-sugar-tinted trays for clients requesting a softer alternative to jet-black synthetic fibers.
