About

Seaport Medspa was founded in 2018 by two board-certified nurse practitioners, Marielle Benayun and Elizabeth O'Neil, who now serve as its co-founders. The practice operates three Massachusetts locations: South Boston on East Broadway, the North End on Salem Street, and Brookline in Washington Square, directly across from the Washington Square Green Line station.

The business describes its focus as safe, natural and balanced results, and says its neurotoxin and filler treatments put safety, patient education and natural-looking outcomes first. The co-founders develop and train every provider through established clinical protocols, hands-on instruction, and a grounding in anatomy, technique and patient safety. According to the business, providers are commission-free, and every complimentary consultation is with a provider.

A visit usually begins with a consultation. The free injectables consultation runs 30 minutes and covers neurotoxins, filler, Sculptra and PRF. There is also a free 30-minute session for people who are unsure where to begin, and a 30-minute wedding planning consultation for brides, grooms and wedding party members. BBL, Moxi, laser hair removal and Morpheus8 each require a consultation before a plan is set, and wellness injections follow a conversation about health goals and preferences.

Signature offerings include the Seaport Medspa Method, a full-face approach to filler that balances multiple areas, and PRF-based treatments such as EZGel, which combines a plasma-derived gel with platelet-rich fibrin made from the patient's own blood. DiamondGlow is a noninvasive treatment that exfoliates, clears pores by suction and infuses serums in a single session. The business says it is nationally recognized in medical aesthetics, and states that it is among the top 1% of Galderma providers nationwide and among the top 4% of providers nationwide for Botox, Juvéderm and DiamondGlow. Appointments can be booked online, by phone at (617) 681-8244, or by email at hello@seaportmedspa.com. Gift cards are sold on the website, and balances can be checked there. The South Boston and Brookline locations have street parking, while the North End has limited street parking with public garages nearby.

Aims for safe, natural and balanced results, with patient education built into neurotoxin and filler care and treatment plans reviewed before any injections.

The South Boston location is described as a serene, modern space.
