Get to Know Us
From the compassion of our team to the effectiveness of our services, Allyn Aesthetics stands out as one of the leading aesthetics destinations in the Nashville area.



Our Story
We’re proud to have built up our practice from humble beginnings into a leading medical spa in Mt. Juliet.
Our owner, Jen Allyn, is a skilled nurse practitioner with years of experience. She started Allyn Aesthetics after a lifetime of inspiration from her father, Dr. Thomas Allyn. Dr. Allyn owned his own medical practice for many years, and Jen grew up learning from him how to be a provider—and a leader.
After establishing herself as an expert nurse practitioner, Jen started Allyn Aesthetics in 2019. Thanks to the lessons from her father, as well as the support of the community, Allyn Aesthetics has thrived. Today, we are the definitive resource for aesthetic care that affirms and enhances natural beauty.


Our Values
At our practice, we always act with honesty with any of our services. We provide real-life, attainable solutions to your aesthetics and wellness concerns.
We’ve built a reputation for dependability and trustworthiness because of the integrity we bring to every client interaction. We do the right thing for our clients—it’s just that simple.
Going to any provider for the first time can be intimidating. But at Allyn Aesthetics, you’ll quickly see how our kindness and compassion puts you at ease.
From punctuality to preparedness to patience, professionalism forms the foundation of our practice and drives every aspect of what we do.
Just as every client's treatment plan is comprised of many goals, your care team is comprised of many members. We recognize that by working together as a team we are so much stronger than any one of us as an individual, and to optimize your care we must act as one. We win together, we lose together, and we support each other, and it shows in the care we provide.

This One’s for the Girls
Jen is passionate about women’s health, and really wants to de-stigmatize the topic of female pelvic concerns, which is why she’s started Girl Talk Tuesday! We meet weekly on Tuesday evenings to discuss all things related to pelvic health and wellness. We’d love it if you’d join us!

Injectables
Our injectable aesthetic treatments are some of our most popular services, and for good reason. You can enjoy transformative, natural-looking renewal with just a few quick, convenient injections! Our injectables range from facial rejuvenation and contouring to skin clearing and even nutrient balancing. At Allyn Aesthetics, there’s something for everyone!
Our facial injectables include proven aesthetics mainstays, such as Botox. With Botox and our other wrinkle relaxers, you can ease muscle tension and alleviate the appearance of wrinkles on your face to fight aging. As they age, many people notice a loss of volume on their face as well. But with fillers, we can restore this volume and re-define your facial profile.
Struggling with skin blemishes like spider veins? Our nurse injectors and laser technicians can help using our targeted spider vein treatment!
At our medical spa in Mt. Juliet, we’ll even provide customized IV therapy to boost your nutrient levels and help you stay energized in your daily life.
Facial Services
Sometimes, you may feel like a more in-depth treatment is required to achieve your ideal look. Say no more—Allyn Aesthetics has you covered with our facial services.
Let us know if you have specific skin concerns and our team can customize your care to your needs with a personalized, medical-grade facial. For clients looking to boost their overall glow, you may be interested in a chemical peel or laser resurfacing.
Many clients visit us to reduce the appearance of their wrinkles. Microneedling is a great option to tighten your skin and increase its overall firmness and tone. While we’re at it, we can also erase pigmentation issues or discolored areas with our intense pulsed light (IPL) therapy.
All of our facial services are minimally invasive and nonsurgical, so you’ll be able to experience major results with minimal downtime when you visit Allyn Aesthetics.
Body and Wellness
Jen Allyn is passionate about the restorative work we do with our body and wellness treatments. Restoring your self-confidence is one of the most significant benefits of any of our treatments. With our wellness services, we can also help return full functionality to your body.
We’re especially proud of our women’s pelvic health treatments. Millions of women develop urinary incontinence and sexual wellness issues caused by weakened pelvic floor muscles. With our noninvasive treatment, we’ll strengthen these muscles, improving symptoms of incontinence and your overall quality of life.
Our wellness services can even restore the quality of your skin! From hair reduction to tattoo removal, we can treat almost every area of the body with our services. Many clients love our EvolveX body contouring service, which can simultaneously build up muscle and eliminate fat in your arms, legs, and torso. You’ll be stronger, look better, and feel more confident after your treatment!
Salon Services
Finally, our salon services are the perfect complement to our other treatments. Whether you need a fresh tan or are trying to get rid of unwanted body hair with wax, you’ll feel refreshed and renewed after visiting us. Our lash and brow services go great with any of our facial treatments.
