RBS Wellness Spa is a physician-led wellness clinic in Redlands, California, founded by Aya Eguchi, MD, a U.S.-trained physician of Japanese heritage. Dr. Eguchi is board-certified in internal medicine and obesity medicine, and provides personalized care that combines evidence-based Western medicine with the attentiveness and hospitality of the Japanese omotenashi tradition. The clinic serves people seeking physician oversight, preventive health support, and individualized medical and aesthetic care.

Medical services include consultations and visits, often available in person or by video, a medically guided weight-loss program, and a menopause wellness program. Weight-management plans use clinically validated approaches and focus on metabolic regulation and long-term maintenance. Menopause care includes medical evaluation, personalized prescriptions, and lifestyle guidance; medications are prescribed but not dispensed at the clinic.

RBS Wellness Spa also offers non-invasive and minimally invasive aesthetic treatments, including wrinkle-relaxing injections, dermal fillers, chemical peels, laser treatments, microneedling, and hair restoration. Across its services, the clinic emphasizes safety, patient education, careful treatment planning, and natural-looking, lasting outcomes.
