Operating inside ColorBar on Fourth Avenue, Park Medspa Hillcrest runs a streamlined injectables practice built around Xeomin, the purified 'naked' neurotoxin that received FDA approval in 2010 and contains no complexing proteins. The Xeomin Challenge pricing model anchors the wrinkle-relaxer program, while Versa dermal filler handles lip and mid-face volume inside the same ColorBar San Diego footprint. The founding physician practices both aesthetics and emergency medicine and co-founded a national Botox training institution, staffing the Hillcrest location with PA and NP injectors rather than estheticians. Treatments focus on the liquid brow lift, lip flip, forehead lines, and glabellar furrows rather than surgical facelifts or energy-device resurfacing. Laser hair removal and tattoo removal fall outside the neurotoxin menu and get routed to device-based providers including LaserAway Hillcrest. The most complex work handled on-site is full-face neuromodulator mapping for patients building tolerance to conventional Botox, where switching to Xeomin's complex-free formulation can restore muscle response.
