Our Medical Spa Services

Advanced treatments, designed around your unique skin

From injectables and lasers to medical-grade skincare, every treatment is chosen based on what will actually make a difference for your skin and goals. Guided by our highly skilled practitioners with attention to detail and your comfort at the forefront, our approach focuses on results that look natural, balanced, and right for you.

Neuromodulators & Biostimulators

Smooth fine lines without looking overdone

Smooth the lines you see now, and help prevent the ones that haven't set in yet. Neurotoxins like Botox® and Daxxify® relax expression lines, while treatments like Sculptra® and Radiesse® work beneath the surface to rebuild collagen and improve skin structure over time.

For deeper skin support, PRP therapy works at a cellular level to improve tone and overall skin quality. Whether you're noticing fine lines, volume loss, or early signs of aging, these treatments deliver natural, balanced results that never feel overdone.

Collagen-Stimulating Treatments

Smoother, firmer skin — without surgery

Smooth texture, refined pores, and firmer skin all start beneath the surface. Treatments like SkinPen® microneedling and RF microneedling stimulate collagen to strengthen and tighten, while chemical peels and BioRePeel® accelerate cell turnover to improve tone, clarity, and overall brightness.

For a more immediate glow, treatments like Glo2Facial® and dermaplaning smooth and brighten the skin. Regenerative options like the Mermaid Facial with PDRN support deeper repair, improving skin quality over time with results that feel tailored to you.

Dermal Fillers

Instantly plump lips & cheeks

Facial contouring at Rocky Mountain Beauty Bar focuses on harmony rather than exaggeration to help lift and rejuvenate your natural features. Dermal fillers are used to enhance lips, define the jawline, and restore balance through the cheeks and chin, creating a more proportionate, refined appearance.

Rather than focusing on a single area, facial balancing considers how your features work together. Every treatment is tailored to your natural structure, so results feel smooth, cohesive, and like you, only more rested and balanced.

Laser Treatments

Reveal smoother, brighter skin

Sun damage, discoloration, and uneven texture can leave skin looking dull and prematurely aged. Advanced laser treatments like skin resurfacing and IPL photofacials target concerns beneath the surface to smooth texture, restore even tone, and stimulate collagen to support long-term skin health.

Laser hair removal, vein treatments, and tattoo removal address unwanted hair and pigment at the source. Whether you're looking to smooth, clear, or remove, these treatments deliver a more even, radiant complexion with minimal downtime.

HAIR RESTORATION & WELLNESS SUPPORT

Restore fuller hair & support your body from within

Hair changes over time, but restoring fuller, healthier growth is possible. Treatments like Alma TED and PRP improve density at the follicle level without surgery or downtime.

Beyond hair, services like medical weight loss supported by GLP-1 medications, IV hydration, and vitamin injections support energy, metabolism, and overall wellness. Finishing treatments like brows, lashes, and waxing refine the details, helping you look polished and confident without the effort.

At Rocky Mountain Beauty Bar, every decision, protocol, and patient experience is rooted in one guiding philosophy: expert care with integrity. We don't just treat features, we treat people. Our goal is to understand what makes you feel like your best self, and to use our medical experience to bring out the most natural, balanced version of you.

Results matter.

Physician-led care

Your treatments are overseen by Dr. Kellie Stivers, MD, a board-certified anesthesiologist. Our team brings deep clinical training, precision, and judgment to every decision, which means safer treatments, better outcomes, and results you can feel confident in.

Honest guidance, not guesswork

We guide you toward what actually works, not just what's popular. If something isn't right for you, we'll tell you. Because the best results come from informed decisions, not trends.

A plan built for you

Your skin and goals evolve over time. That's why we focus on personalized treatment plans, not quick fixes, and combine the right services at the right time to create results that build naturally.

Designed for long-term results

Every treatment is designed around your unique features, not a template. The goal isn't to look different. It's to look refreshed, balanced, and like yourself at your best.

THE RMBB CARES Consult

Let’s build an aesthetic plan personalized to you

Most practices start with treatments. We start with a plan. Every treatment begins by understanding your skin, your goals, and what will actually work before you commit to anything.

Understand what your skin actually needs

Every face, concern, and goal is different. The CARES Consult is designed to understand your skin, your anatomy, and what will actually work, so you're not left guessing or choosing treatments based on trends.

Kellie and everyone I've interacted with has been so kind and knowledgeable. She helped me put together a plan for my skin and scars that I was comfortable with and in my price range. Really happy with the results. I'll never go anywhere else for my skincare needs!

Rocky Mountain Beauty Bar absolutely came through for me. Kellie and her team were calm, kind, and on it immediately. The whole experience felt safe, clean, and genuinely personal, like I wasn't just another appointment on the calendar. Within a short time, I felt like a new person. Highly recommend.
