About Mar Santiago, FNP-C

I am a Family Nurse Practitioner with more than 20 years in medicine, bringing advanced clinical training into the world of aesthetic medicine in Dallas, TX. My approach is thoughtful, precise, and grounded in evidence-based care, ensuring every treatment is performed with intention and a deep understanding of facial anatomy.

Education & Credentials

I earned my Bachelor of Science in Nursing and Master of Science in Nursing from Texas Woman’s University, where I completed my Family Nurse Practitioner training. I am board-certified through the American Association of Nurse Practitioners (AANP) and specialize in aesthetic treatments including wrinkle relaxers, dermal fillers, collagen-stimulating treatments, and full-face rejuvenation designed to deliver natural, balanced results.

Philosophy & Approach

My passion for aesthetics comes from a deep belief that confidence and self-care play a powerful role in overall health and well-being. I am dedicated not only to helping patients look their best, but to helping them feel confident, refreshed, and aligned with the best version of themselves. My goal is to enhance—not change—your natural features through personalized, expert care.

Serving patients in Dallas and Highland Park, I take a full-face, individualized approach to every treatment plan. I believe the most meaningful results come from careful listening, attention to detail, and a commitment to creating results that feel authentic, refined, and long-lasting.

Wrinkle Relaxer

Wrinkle relaxer treatments are among the most popular options for reducing the appearance of forehead lines, frown lines, and crow’s feet.

Specialty Neurotoxin Treatments

Wrinkle relaxers work by gently relaxing targeted facial muscles that contribute to the formation of expression lines and wrinkles.

Dermal Fillers

Dermal fillers are an excellent option for facial balancing and volume restoration after weight loss or aging, areas where natural fat and collagen may decrease over time.

Biostimulators

Treatments are carefully customized to restore volume, improve skin support, and enhance facial balance while maintaining a refreshed, natural appearance.

Microneedling

Microneedling is an advanced skin rejuvenation treatment designed to improve skin texture, tone, fine lines, acne scars, and overall skin quality by stimulating the body’s natural collagen and elastin production.

Men's Aesthetic Treatments

Many men seek treatment to look less tired, improve skin quality, reduce forehead lines, or enhance areas such as the jawline, chin, and under-eye area while maintaining a natural look.

Medical Weight Management

Every weight management plan is customized following a thorough consultation to review medical history, goals, and expectations. Our approach focuses on safe, sustainable support.

Hormone Optimization & Wellness

Hormone Replacement Therapy (HRT) is carefully prescribed and monitored to ensure safety and effectiveness.

I would follow Mar anywhere! I'm so excited that she has started her own business. She exudes knowledge and passion for all things related to not only skincare but whole body care (HRT/Hair). She truly is an expert and is always continually learning about the newest aesthetic procedures. As a total bonus, she has the best personality and not only makes you feel comfortable but will have you laughing your head off! ❤️
