CUSTOM TREATMENTS THAT MEET YOUR NEEDS
INJECTABLES
Injectables are our specialty – everything from Botox to fillers and Dysport to Sculptra. Administered by Master Injectors, these treatments target fine lines and wrinkles, smooth and hydrate the skin, restore lost volume, and so much more. Whether used as a preventative measure or to target specific concerns, our suite of injectables includes something for everyone.
PRP / PRFM
To address specific issues like acne scarring, thinning hair, or dull skin, we default to PRP. Our Platelet Rich Plasma (PRP) treatments work by injecting isolated platelets rich in growth-inducing stem cells from a patient’s own blood to stimulate collagen production in a particular area. As a result, your skin will be left smoother with revived elasticity.
FACIAL TREATMENTS
If you’re new to skincare, this is the perfect place to start. Our suite of non-invasive facial treatments range from preventative, to maintenance, to corrective services. Brightening DiamondGlow facials using medical-grade skincare, chemical peels, Morpheus8, BBL, Moxi, microneedling Clear + Brilliant, and more, we have treatments for every skin type.
OUR PRODUCTS
We use only premium, medical-grade skincare and cutting-edge technology to deliver the best results.

GLOWING TESTIMONIALS FROM OUR CLIENTS
what they're saying
THE FOUNDERS
Medically Trained. Fully Certified. Creatively Driven.
We believe injectables are to wrinkles as hair dye is to grays. But, in order to kick the societal stigma around these preventative and corrective treatments, we’re committed to a conservative, custom, and considered approach that’s backed by science and fueled by creativity. That means, everyone at Seaport Medspa is not only a master of their craft, but dedicated to offering honest consult and delivering your best results – not just bank a buck.
