About JASI Skin + Wellness Med Spa · Los Angeles
JASI Skin + Wellness Med Spa is a multi-location medical aesthetics practice headquartered at 11695 National Blvd in West Los Angeles, founded by Family Nurse Practitioner Ginille Brown (Stanford- and Duke-trained). The Los Angeles flagship offers the full JASI treatment menu — injectables, laser and skin therapies, hair restoration, and medical weight loss — to clients across West LA, Brentwood, Westwood, Culver City, Santa Monica, Marina del Rey, and Venice. The practice is rated 5.0 stars across roughly 290+ Google reviews and operates a 30-day satisfaction guarantee on all treatments.
JASI Skin + Wellness Med Spa (formerly Ginille Beauty Aesthetics) traces its origins to 2013, when founder Ginille Brown, NP, began treating patients as a solo aesthetic injector in Los Angeles. After earning her undergraduate degree at Stanford University and her nursing credentials at the Duke University School of Nursing, Brown built her practice around a 'less is more,' full-face harmonization philosophy and a consultative approach that emphasizes listening over upselling. Over thirteen years the brand expanded into a three-location medical spa with clinics in West Los Angeles (11695 National Blvd), Torrance (21250 Hawthorne Blvd, Suite 170 – Studio 107), and Las Vegas (8861 W. Sahara Ave, Suite 190), collectively trusted by more than 2,000 clients. The Los Angeles location is the flagship, offering the complete JASI service menu alongside a proprietary JASI Skincare product line, virtual consultations, Cherry financing, and membership plans. Every provider is hand-selected and personally trained by Brown, and the clinic maintains protocols specifically calibrated for diverse skin tones — a point of emphasis given Brown's identity as a Filipino and Black founder in an industry where practitioners of color remain underrepresented.
