Services
Botox
Botox injections reduce facial wrinkles by temporarily relaxing muscle activity. This FDA-approved treatment addresses forehead lines, crow's feet, and frown lines while maintaining natural expressions. Patients typically see results within 3-10 days with effects lasting 3-4 months. Our experienced providers customize treatment plans to achieve subtle, refreshed appearances while maintaining facial mobility.
Dermal Fillers
Dermal fillers restore lost facial volume and smooth wrinkles using hyaluronic acid-based products like Juvederm and Restylane. Treatments address smile lines, cheek hollows, and lip thinning while providing immediate visible improvements. Results last 3 months to 2 years depending on product selection and injection site. Our specialists conduct thorough consultations to determine optimal filler types and volumes for natural-looking enhancement.
Skin Tightening
TempSure Envi skin tightening uses radiofrequency technology to stimulate collagen production without surgery. This noninvasive treatment addresses facial and body skin laxity, cellulite, and wrinkles while promoting skin rejuvenation. Patients experience tightening effects immediately with continued improvement over 4-6 weeks. Annual maintenance sessions help sustain results while improving skin texture and elasticity through natural collagen regeneration.
Weight Loss
Our medically supervised very low-calorie diet (VLCD) program helps patients lose 3-5 pounds weekly through structured meal replacements. Designed for individuals with BMI over 30, this 12-week program includes physician monitoring to manage side effects and ensure nutritional adequacy. We provide ongoing support for transitioning to sustainable lifestyle changes, with regular follow-ups to prevent weight regain and maintain metabolic health improvements.
Skin Pen Micro Needling
SkinPen microneedling stimulates collagen and elastin production to improve acne scars and neck wrinkles. This FDA-cleared treatment creates controlled micro-injuries that trigger the skin's natural healing response. Patients typically require 3 sessions spaced 4-6 weeks apart for optimal results. Post-treatment care includes sun protection and skincare guidance to maximize collagen production and maintain skin rejuvenation effects over 3-6 months.
