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

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

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.

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

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.

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.

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

Yes. Board-certified nurse practitioners with specialized aesthetic training, like Mar Santiago, are qualified medical providers who can safely evaluate, prescribe, and administer injectable treatments such as Botox, dermal fillers, and biostimulators. Mar Santiago holds a Bachelor of Science in Nursing and a Master of Science in Nursing from Texas Woman’s University, completed Family Nurse Practitioner training, and is board-certified through the AANP. This clinical background, paired with advanced aesthetic training, allows for safe, precise, and medically sound treatment planning for every patient in Highland Park.
The right treatment depends on individual goals, skin quality, and facial anatomy. During a consultation, Mar Santiago reviews medical history, current concerns, and desired outcomes to recommend the most effective option — whether that is wrinkle relaxers for expression lines, biostimulators for gradual collagen rebuilding, microneedling for texture and scarring, or hormone optimization & wellness for energy and metabolic support. Patients are welcome to contact us to schedule a personalized consultation.
Botox and other wrinkle relaxers work by gently relaxing the facial muscles responsible for expression lines like forehead lines, frown lines, and crow’s feet. Dermal fillers, on the other hand, restore lost volume using hyaluronic acid, addressing areas such as the lips, cheeks, jawline, and under-eyes. Many patients combine Botox with fillers as part of a full-face treatment plan for balanced, natural-looking results.
Botox pricing depends on the number of units needed to treat each area, which varies by individual anatomy and goals. Because dosing is customized during a consultation rather than sold as a flat package, patients in Highland Park and University Park receive an accurate, personalized quote after their assessment. Visit the Botox page to learn more about treatment areas and what influences cost.
Biostimulators are injectable treatments that stimulate the body’s own natural collagen production rather than simply adding volume. Sculptra® and RADIESSE® are used for gradual, long-term facial rejuvenation, improving skin quality, firmness, and structural support over the months following treatment — a popular choice for patients seeking subtle, progressive results.
Most patients need a series of microneedling sessions to achieve optimal improvement in skin texture, tone, fine lines, and acne scars, since results build progressively as the body produces new collagen and elastin. The exact number of sessions depends on individual skin concerns and goals, which is why every microneedling plan is customized after a consultation, sometimes paired with skin boosters or exosome therapy to accelerate recovery.
Hormone optimization & wellness is a medically supervised approach to improving energy, metabolism, and overall well-being for both men and women. As hormone levels decline with age, patients may experience fatigue, weight gain, reduced muscle mass, brain fog, and mood changes. Treatment options include Hormone Replacement Therapy (HRT) and peptide therapy, both guided by comprehensive lab evaluation and an individualized plan.
Yes. Board-certified, aesthetically trained nurse practitioners are licensed medical providers qualified to evaluate patients and safely administer injectables such as Botox, dermal fillers, and biostimulators. Mar Santiago brings over 20 years of medical experience and AANP board certification to every treatment plan for patients in Highland Park and University Park.
Men’s aesthetic treatments are dosed and designed specifically for masculine facial anatomy, which typically has stronger bone structure, flatter cheeks, and more defined angles than female anatomy. Popular treatments include wrinkle relaxers for forehead lines, dermal fillers for jawline and chin enhancement, hyperhidrosis (excessive sweating) treatment, and collagen-stimulating skin rejuvenation — all designed to preserve a natural, masculine, rested appearance.
Medical weight management is a personalized, medically supervised program built around a thorough consultation reviewing medical history, goals, and expectations. The approach focuses on safe, sustainable weight loss and metabolic support, which can also enhance aesthetic outcomes like facial definition and body contours.
PDO thread treatments provide subtle lifting, structural support, and ongoing skin quality improvement as the body’s natural collagen production continues to develop after treatment. Popular options include the Full Face PDO Lift, Lower Jawline Lift, Eyebrow Lift, and Fox Eye Lift, with benefits that continue to improve well beyond the initial appointment.
The best way to determine the right treatment is a one-on-one consultation. Mar Santiago reviews your goals, facial anatomy, and medical history to build a customized plan — whether that includes wrinkle relaxers, dermal fillers, biostimulators, microneedling, or hormone optimization & wellness.
