French bath and body boutique at 935 Prospect St, La Jolla, CA 92037, walking distance from La Jolla Cove. Owners Lydia and Francois Xavier relocated from Marseille to bring authentic Savon de Marseille — a 600-year-old recipe using just freshwater, sea salt, natural lye, and vegetable oil — to San Diego. The shop stocks handmade bar soaps ($8 each or four for $30), cube soaps ($9 each or four for $34), body washes, essential oils, men's and women's fragrances, natural sea sponges, Provençal table linens from Nice, and bath salts. The product line is anti-bacterial, hypoallergenic, and biodegradable. Xavier trained under a soap master in France and is the only purveyor of the native Marseille product in San Diego and Riverside counties — a specificity that separates the shop from the broader luxury bath selection at Bluemercury on Girard Avenue, which carries dozens of brands but nothing hand-crafted from a single-origin Provençal source. The Prospect Street block also hosts La Jolla Med Spa at 850 Prospect for clients pairing artisan skincare products with professional facial treatments.
