Services
BOTOX Cosmetic
BOTOX Cosmetic reduces dynamic facial lines by temporarily relaxing targeted muscles. Ideal for frown lines, forehead wrinkles, and crow's feet, it uses purified botulinum toxin to smooth expressions. Results appear within a week, lasting 3-6 months, with minimal downtime and immediate return to daily activities.
JUVDERM Fillers
JUVDERM hyaluronic acid fillers restore volume and smooth wrinkles by replenishing natural skin hydration. Treatments address nasolabial folds, lips, cheeks, and marionette lines, with results lasting 6-24 months depending on product type. The smooth-gel formula stimulates collagen production for long-term rejuvenation.
KYBELLA
KYBELLA eliminates submental fat through synthetic deoxycholic acid injections, destroying fat cells for a defined jawline. Requires 2-4 sessions spaced 1 month apart, with permanent results as treated fat cells cannot regenerate. Mild swelling and bruising resolve within weeks.
Laser Hair Removal
CoolGlide laser targets hair follicles for permanent reduction, suitable for all skin tones. Treatments require 4-8 sessions for optimal results, with minimal discomfort and no downtime. Effective for facial and body areas, including sensitive zones like the bikini line.
Medical Weight Loss
Physician-supervised programs combine personalized nutrition, behavior modification, and medical interventions like ProLon fasting. Patients receive metabolic assessments, progress tracking, and support for sustainable weight loss, addressing obesity-related conditions such as diabetes and hypertension.

First impression: clean, bright, and friendly. Abby is so sweet and makes you comfortable the second you walk through the door. I found Millenium on Instagram and really wanted to do the prp facial when they had a sale last month. I am so happy I found them! Dr. O'Brien is great and the results were amazing! Dr. O'Brien made sure to tell me everything about the treatment.good and bad. Did not try to sugarcoat it for me. (Speaking as someone with a few tattoos who tried numbing cream, I knew it could only do so much anyway.) It was nice that she let me know and emphasized it, before I made my decision.

The bit of discomfort and aftercare was what Dr. O'Brien had already described and warned me of. Now that the redness has completely gone, I am SO HAPPY with the results! My acne scars are virtually gone and I think my skin texture is 100x better. Thank you Millennium, I'll be back!
