Injectable Services

BOTOX® Cosmetic

BOTOX® Cosmetic is an FDA-approved injectable that softens the look of wrinkles and fine lines. BOTOX® is commonly used on the forehead, crow’s feet, frown lines and horizontal lines between your eyebrows. Results typically last three to four months.


Yes, even men get BOTOX®! Over 1 million men to be exact. This injectable service provides men with a subtle, natural look by softening forehead lines, crow’s feet, frown lines and sunken eyebrow areas. BOTOX® can also be used to manage excessive sweating in men and women.


This treatment destroys moderate to severe fat below the chin. KYBELLA® (deoxycholic acid) breaks down the absorption of dietary fat to create the contouring effect and visibly improves the jawline. Two or three treatments performed every six weeks are recommended to eliminate the “double chin.” Results are permanent.


For those looking to correct facial wrinkles and folds around the nose and mouth, or the parenthesis lines, this injectable adds volume to the skin and gives it a smoother appearance. Results last up to one year.

JUVÉDERM® Ultra Plus & Ultra XC

A gel injectable that adds fullness and plumpness to lips. Ultra XC is also approved to smooth and correct moderate to severe parentheses lines, such as the nasolabial folds. Results last up to one year.


A gel injectable that focuses on contouring and lifting the cheeks by instantly adding volume beneath the skin. VOLUMA® XC will provide you with a more youthful profile with results lasting up to two years.


A gel injectable that targets the lips and mouth by adding fullness to lips and corrects the lines around the mouth, also known as “smoker’s lines”. Results can last up to one year.


A gel injectable that treats moderate to severe facial wrinkles, volume loss and folds, including the “parentheses lines” around the nose and mouth. VOLLURE™ XC gives skin a smoother appearance by temporarily diminishing facial wrinkles. Results last up to 18 months.

Skin Services


Coming soon! This patented, non-invasive treatment works to exfoliate, extract and infuse skin with serums that can be tailored to your skin’s needs and concerns. After a DermalInfusion treatment, skin will have enhanced volume, gain hydration, tone, and texture. Results are immediate and long lasting with no down time.


This pain-free treatment takes under 30 minutes with no downtime or recovery needed. AquaGold® provides similar benefits to microneedling by using 24-karat gold needles and patented micro-channeling technology to evenly distribute cosmetic injectables. The treatment targets concerns like signs of aging, skin damage, loss of volume, uneven tone or texture, acne scars or skin rejuvenation in large areas. Results are seen 3-7 days after treatment and can last up to 4 months.

The SkinPen

The SkinPen is an FDA-approved, medical-grade microneedling device that also known as collagen induction therapy. Safe for all skin types, the treatment rejuvenates the skin, increases collagen formation to soften the appearance of stretch marks, acne scars, fine lines and wrinkles. The number of treatments depends on your skin’s condition and goals with most, significant results occurring four to six weeks after. Our technology is the most efficient microneedling tool on the market.

VI Peel®

A gentle yet medical-grade chemical peel, the VI Peel® treats many skin pigment and imperfection issues such as hyperpigmentation, melasma, rosacea, acne and acne scarring, fine lines, wrinkles and sun or age spots. The Peel process takes three to four days before health new, tissue begins to show. After about a week, the skin should look smooth, soft and luminous.
