Define Aesthetics Studio

Define Aesthetics Studio is a boutique aesthetic practice operating inside Salon Republic in Murrieta, California, founded by Wendy Ferguson, RN, MSN, alongside co-founder and Medical Director Yalda Sedghi, MD. This nursing-and-physician team brings combined clinical and aesthetic expertise to a practice built on conservative, natural-looking results rather than overtreatment. The studio's philosophy emphasizes top-tier products and techniques tailored to each client's unique features, prioritizing a warm, professional client experience over volume-based service. Define Aesthetics Studio's treatment menu centers on injectable neurotoxins such as Botox, dermal fillers, and biostimulator treatments for longer-lasting facial volume and collagen support. The studio also offers chemical peels and microneedling for skin texture and tone, along with Xerf, a lift-and-firm treatment for skin tightening. A curated professional-grade skincare line is available for clients to continue results at home, and multiple financing options, including Alle and CareCredit, as well as the studio's own Xperience Program, help make treatments more accessible. The combination of RN and MD-level credentials, along with a focus on natural, understated enhancement, distinguishes Define Aesthetics Studio within the Murrieta aesthetic market.
