EverSun Beauty & Wellness in Carlsbad's La Costa corridor — the rebranded evolution of iTAN Sun Spray Spa, founded in 2001 — delivers light therapy, indoor tanning, and sunless spray services from a suite on El Camino Real. The multi-modality menu includes red light therapy for collagen stimulation, infrared therapy for detoxification and cellulite reduction, Matrix high-pressure UV beds, and automated VersaSpa spray booths, a wellness scope that extends the relaxation programming at North County Spa along the Carlsbad coast. WellFit skincare treatments target fine lines and uneven tone through a combination of LED wavelengths and topical serums applied in post-session protocols. With 28 locations spanning San Diego, Riverside, Orange, and Santa Clara counties, the La Costa branch serves the Aviara, Bressi Ranch, and greater Carlsbad market alongside the brow and lash aesthetics at Brow Envy on Roosevelt Street. Red light panels in the therapy beds emit wavelengths at 633 nm and 830 nm to target both dermal collagen synthesis and deeper tissue inflammation reduction in a single 20-minute session.
