Services
Botox Injections
Botox injections temporarily reduce facial wrinkles by relaxing underlying muscles. This popular treatment targets dynamic wrinkles like frown lines and crow's feet with minimal downtime. Results appear within 3-7 days and last 3-4 months, offering a refreshed appearance while maintaining natural facial expressions.
HydraFacial Treatments
HydraFacial combines cleansing, exfoliation, and hydration using patented vortex technology. This multi-step treatment addresses fine lines, uneven texture, and congested pores while delivering antioxidants and hyaluronic acid. Suitable for all skin types, it provides immediate glow and long-term skin health improvements through regular sessions.
Skin Tightening
Non-surgical skin tightening uses radiofrequency or laser energy to stimulate collagen production. This treatment improves sagging skin on the face and neck without incisions. Multiple sessions yield gradual lifting effects, ideal for those seeking subtle rejuvenation without downtime or surgical risks.
Dermal Fillers
Dermal fillers restore lost volume and smooth facial contours using hyaluronic acid or biostimulating formulas. Common applications include lip augmentation, cheek enhancement, and nasolabial fold reduction. Results are immediate with varying longevity (6-24 months) depending on product type and treatment area.
Microneedling
Microneedling creates micro-injuries to stimulate collagen and elastin production. This treatment improves acne scars, fine lines, and uneven texture through controlled skin regeneration. Combining with topical serums enhances absorption for optimized results, requiring multiple sessions for progressive skin rejuvenation.

I relocated to the area a few months ago and was looking for a new medical spa did my research and decided to go to to Entre Nous. I wanted to get 3 procedures done which I had done plenty of times in the past so I know what to look for when picking a place.
Scheduling seems to be impossible and they seem to be close prompt at 5 pm and hours on Saturdays are limited which caused endless calls and emails to even schedule something. My first appointment that I was looking forward too got cancelled. Second appointment was on a Saturday for dysport. I specifically told the nurse I want no movement

I have been seeing Sandra for a few years for Botox treatments! I must say she is great at what she does -especially since i have a phobia of needles or shots! She is not only experienced but knows how to put someone at ease! I always enjoy my visits there and so must say this place is above professional! i was there today and during these covid times they are taking extra precautions to be sure all are safe! I used a special knob to enter the salon and then was greeted by the receptionist to have the soles of my shoes checked, and then my temp checked followed by questions about my health! This

Enter Nous Aesthetics is incredible. I am so grateful I found a place close to home that I trust and does incredible service. Sandra is amazing and the only one I'd trust with doing my botox. I have even been during this crazy Covid-19 time and I felt so safe. They have an amazing protocol that you have to follow and wear all the protective gear. I'm so grateful they have been able to remain open during this time.

Fantastic. I've known Sandra for many years since her stint at PAMF and I'm glad I've been able to stay connected with her ever since. She has mastered her craft. I'm very happy with the results of all her treatments. I recently met Sarah and she did the best hydrafacial I've ever had. I'm not saying that lightly either. She addressed all my concerns and provided solutions. It's a great place with a lovely, attentive staff. When I decide to have something more aggressive done, Dr. Weston will be the one to do it.
