About Benicia Medical Aesthetics
Benicia Medical Aesthetics is a medical spa at 701 Southampton Rd, Suite 104, in Benicia, California, owned and led by Janeeh Miranda, MSN, FNP-C, a board-certified nurse practitioner. Every treatment plan starts with her, and every protocol runs under the oversight of Sundar Natajaran, M.D.

She came to aesthetics from medicine. Janeeh has spent more than 12 years in the medical field and is trained in acute care medicine as well as aesthetics. In her own words, her “passion for helping people feel their best” led her to specialize in medical aesthetics, with a “safe, custom, patient-centered approach.”
Some patients have been with her from the start:
“I love this place!! I've been coming since they opened and have done facials, 3 sessions of micro-needling, Botox etc. The environment is really welcoming. I see Janeeh and she's very thoughtful and calculated with recommendations (versus churn and burn with other chain med spas) so I feel taken care of.”
What we believe about aesthetic treatment
These are the rules the practice runs on. Patients mention them in their reviews more than any treatment.
-
The plan comes before the product.
Janeeh examines your skin and listens to what bothers you before she recommends anything. You hear what she would treat, in what order, and what it costs, before a single appointment is booked.
When a plan runs over months, a membership often costs less.
-
Conservative on purpose.
It's easy to add a little more filler at a follow-up, and much harder to take too much away. Janeeh aims for results people notice as “rested,” and builds up over visits instead of overdoing one.
-
You'll hear what you don't need.
If a treatment won't help, you'll hear it at the consultation. Patients say it better than we can:
“She took her time and explained everything while not trying to pressure me into purchasing things that I did not need.”
“She will only recommend what's necessary.”
-
A physician oversees every protocol.
Sundar Natajaran, M.D., has practiced internal medicine for more than 20 years, mostly as a hospitalist, and has worked in aesthetics for more than 10. He supervises the medical protocols behind every treatment here. He does not perform treatments.
-
Medical-grade products only.
Janeeh uses “only the highest quality medical-grade products,” her words, from the injectables to the skincare on our shelves.

What patients say
“I absolutely love this place it's a true hidden gem in Benicia. First of all, they never ask for tips, which already says a lot about their professionalism and integrity. I honestly can't stand places that make you feel uncomfortable or guilty about tipping, this place respects you and focuses on quality service instead.”
