Skin by Carissa in Chula Vista's Otay Ranch area brings a Master Esthetician's credential and a California license dating to 2012 to a private studio on East Palomar Street. Custom facial protocols begin with a skin-type analysis that determines cleansing agents, exfoliation depth, and serum selection before any extraction work begins — a diagnostic-first model shared by the precision colorists at Laura Mathew Salon in the broader Chula Vista beauty network. Dermaplaning sessions use a single-use surgical scalpel angled at 45 degrees across the epidermis to remove vellus hair and dead-cell buildup, improving product absorption for the serums layered immediately afterward. The studio sits in the 91913 ZIP code along the East Palomar Street corridor between Telegraph Canyon Road and Otay Ranch Town Center, placing it within the eastern Chula Vista commercial zone, sharing a wellness-minded client base with Pilates of Eastlake on the Eastlake fitness circuit. Each dermaplaning blade is a #10 sterile surgical-grade stainless-steel instrument replaced between clients to maintain aseptic technique across the full 60-minute treatment sequence.
