Dr. Samantha Ellis is a board-certified medical and cosmetic dermatologist based in Danville, California. She is the founder of Prequel, a modern skincare brand that offers dermatologist-developed products designed to optimize skin health and be safe for those with chronic skin conditions.
Early Life and Education
Dr. Samantha Ellis was born and raised in California. She graduated summa cum laude with a Bachelor of Science in Biology from the University of California, Los Angeles.[5] Her exceptional academic performance earned her the prestigious Dean's Merit Scholarship to attend the University of Michigan Medical School, where she completed her medical doctorate.[5] While at medical school, Dr. Ellis was inducted into the Alpha Omega Alpha medical honor society in recognition of her outstanding academic achievements and leadership skills.[5]
After finishing her medical internship in Denver, Colorado, Dr. Ellis returned to California to complete her dermatology residency at the University of California, Davis.[5] During her residency, she published multiple peer-reviewed journal articles and authored several medical textbook chapters on various dermatology topics, including cutaneous immunology, dermatologic surgery, cosmeceuticals, and skin aging.[5] Dr. Ellis also dedicates her time to educating the next generation of dermatologists by serving as a Clinical Instructor of Dermatology at UC Davis.[5]
Founding Prequel Skincare
Dr. Samantha Ellis launched Prequel, her dermatologist-developed skincare brand, in July 2023 in collaboration with The Center, a Los Angeles-based brand accelerator.[1][4] The brand was born out of Dr. Ellis's experience as a practicing dermatologist, where she identified a gap in the market for advanced, accessible skincare formulations that could address a wide range of skin concerns.[2]
Prequel's product philosophy is centered around what Dr. Ellis calls "basic plus" - taking tried-and-true dermatological ingredients and elevating them through innovative formulations, packaging, and user experience.[1][2] The brand aims to provide effective, cosmetically elegant formulas that are accessible to everyone, bridging the gap between doctor's office brands, prescription topicals, and over-the-counter basics.[4]
The initial product line includes three core products:
1. Gleanser: A non-drying glycerin cleanser for face and body, formulated with 50% glycerin, inulin, and a unique aquaporin-stimulating active.[1][4]
2. Skin Utility Ointment: A multi-purpose skin protectant with 45% USP-grade petrolatum.[1][4]
3. Urea Repair 10% Urea Moisturizing Milk: A hydrating formula combining 10% pure urea with shea butter, glycerin, and niacinamide.[1][4]
These products are designed to address various skin concerns, from aging and acne to crepiness and hyperpigmentation, while focusing on restoring the skin barrier and promoting overall skin health.[1][4]
Dr. Ellis's unique position as both a dermatologist and a skincare enthusiast with a significant social media following has been instrumental in shaping Prequel's approach. According to Ben Bennett, founder and CEO of The Center, "Prequel is inspired by Sam's ability to utilize her unique positioning between the dermatological world and the social media landscape, for skincare and product education."[1]
To ensure the brand's scientific credibility and educational focus, Prequel has assembled an advisory board of experts, including cosmetic chemists Javon Ford, Esther Olu, and Jane Tsui.[2] This team of specialists contributes to the brand's commitment to skin barrier health and education.
Prequel launched exclusively online at www.prequelskin.com, making its dermatologist-developed products directly accessible to consumers.[1][4] The brand's creation reflects Dr. Ellis's goal of providing effective, elegant skincare solutions that can be used preventatively, "before you ever need to see a dermatologist."[2]
Innovations in Dermatology
Dermatology is a rapidly evolving field with numerous innovations emerging to improve diagnosis, treatment, and patient care. Some key recent advancements include:
Artificial Intelligence in Laser Hair Removal: New algorithms called advanced automatic target recognition (ATR) use digital skin images to precisely locate hair follicles for removal. This AI-mediated approach offers increased accuracy, reduced risk of human error, and potentially fewer side effects compared to traditional laser hair removal techniques.[1]
Emsculpt for Non-Invasive Body Contouring: This FDA-cleared treatment uses high-intensity focused electromagnetic (HIFEM) energy to induce muscle contractions, promoting muscle toning and fat reduction. A 30-minute Emsculpt session reportedly equates to 20,000 crunches or sit-ups.[1]
Molecular Skin Rejuvenation (MRBL): This next-generation gene therapy takes a comprehensive approach to treat both monogenic and polygenic skin diseases, as well as visible signs of aging. It utilizes a computational target discovery platform with cell-specific gene delivery vehicles to deliver genetic "payloads" to specific areas of a patient's skin.[1]
Advanced Diagnostics: Innovations in this area are making skin disease identification easier for both medical professionals and patients at home. These tools often rely on artificial intelligence and machine learning to improve accuracy and speed of diagnosis.[3]
Pharmaceutical Dermatology: Research is ongoing in the development and testing of new drugs, including topical, oral, and injected medicines, to treat a variety of skin conditions more effectively.[3]
Digital Dermatology: This encompasses innovations in telemedicine, electronic medical records, and artificial intelligence applications in dermatological practice. These technologies are helping to address the shortage of dermatology professionals by improving efficiency and expanding access to care.[3][4]
Gene and Cell-Based Therapies: According to Dr. Rox Anderson, director of the Wellman Center for Photomedicine at Harvard Medical School, a "tsunami" of gene and cell-based therapies for skin treatment is on the horizon. This includes the potential application of CAR T-cell therapy, currently used in cancer treatment, to dermatological conditions.[5]
CRISPR Technology: Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) genome editing technology shows promise for treating genetic skin disorders, particularly epidermal blistering disorders.[5]
Full-Thickness Coring Needle Devices: These devices allow for grafting and removing skin laxity without scarring, enabling faster wound closures. They work by initiating a skin repair process through the formation of new collagen and elastin fibers.[5]
These innovations represent significant advancements in dermatological care, offering new possibilities for more effective, precise, and less invasive treatments across a wide range of skin conditions and cosmetic concerns.
