My goal is to help you become a more refreshed version of yourself both inside and out. Listening to your concerns is the foundation of my approach. Together, we will create a plan to help maintain your results and tailor them to your lifestyle.
skin & Wellness Consultations
Discuss all your skincare woes with us and determine what may be causing the problem.
-
We take a more holistic approach to treating skin ailments. We believe in understanding what may be causing your issue and removing the source instead of just treating the symptoms. We will provide prescriptions when necessary, but our ultimate goal is to pinpoint the cause. We also offer some natural options for treatment. Christina has worked in dermatology for many years and has extensive experience treating acne and rashes.
Injectables
Smooth out wrinkles, reduce tension, replace lost volume, and add contour. We use neuromodulators and conservative amounts of filler to create a lifted, more relaxed, natural appearance.
-
Neuromodulators (Botox/Dysport/Jeauveau/Xeomin) are most commonly used to treat forehead lines and crow’s feet. These can also be used on the lower face and neck to create a lifting effect and a more relaxed overall appearance. In the hands of an experienced injector many areas of concern can be treated with neuromodulation including flared nostrils, a gummy smile, chin dimpling, a turned-down smile, marionette lines, jowls, TMJ, and lips.
-
Dermal Hyaluronic Acid Filler (Restylane/Versa/Belotero/Juvederm) replaces lost volume in the cheeks, temples, chin, lips, nasolabial folds, marionette lines, under the eyes, and jaw.
-
We also offer Skinvive injections for improved skin hydration and texture. Results can be seen in 2-4 weeks and last up to 6 months.
-
We use Asclera (an injectable sclerosing agent) to treat visible spider veins on the legs. Compression stockings/socks should be worn immediately after treatment and continuously for the first 2-3 days post-treatment. This treatment is not meant for bulging varicose veins which should be evaluated and treated by a vascular surgeon.
Lasers & Skin Rejuvenation
We utilize state-of-the-art lasers, lights, and energy-based devices to rejuvenate and tighten the skin while stimulating collagen and elastin production.
-
We offer IPL (intense pulsed light) to treat sun damage (brown spots) and redness. IPL can also be used to treat bruises or post-inflammatory hyperpigmentation. An IPL photofacial is a popular procedure to treat sun damage and red vessels on the face but this device can be used on the chest, hands, and body as well.
-
Our Genius RF microneedling device improves fine lines, acne scarring, large pores, and any textural unevenness while also tightening the skin. The radiofrequency heat is delivered into the deeper layers of the skin to promote tightening and boost collagen production.
SkinPen microneedling is used to treat uneven texture and promote an overall glow. This procedure boosts collagen production and smooths acne scars or noticeable pores/texture.
-
Ulthera skin tightening is also available upon request. This device uses ultrasound-delivered heat to cause tissue contraction deeper down, above the muscle, and also treats the dermis to promote collagen production and tissue healing. This treatment only requires one session to see significant results. It can be used on all skin types at any time of the year.
-
Laser Hair Removal for permanent hair reduction. Best for dark hair and will not treat blonde or white hair. Safe for all skin types.
-
Lightweight peels with minimal downtime.
TCA Peels
TCA cross for deeper acne scarring.
Aesthetic Regenerative Medicine
Address signs of aging by stimulating collagen production and tissue healing through the body's natural healing process.
-
PRP and PRF (platelet-rich plasma/fibrin) injections for skin rejuvenation and hair growth stimulation. PRP can be used instead of filler in delicate areas like the under eye to stimulate tissue repair and improve the appearance of dark circles and crepey skin. PRP is also often used for hair restoration. This procedure involves drawing your blood, spinning it down to separate the platelet-rich plasma and injecting the PRP into the area to be rejuvenated.
-
Biostimulatory injections (Sculptra) replace volume loss over time and stimulate collagen production. Great for someone who wants overall subtle volume replacement and skin glow.
-
Enhance any Microneedling treatment with PDGF or VAMP (PDRN plus topical vitamins and amino acids) to treat acne scarring, fine lines and promote an overall youthful glow.
