Marissa's List Of Services

Botox and Dysport are neuromodulators that temporarily relax the facial muscles that cause wrinkles. Common treatment areas include the forehead, 11’s, crow’s feet, masseter, and neck. The treatment requires no downtime and may cause minimal bruising. Results are seen within 14 days and last about 3 months.

Dermal fillers are used to restore lost volume, reduce facial creases, and enhance facial features. Common treatment areas include lips, perioral lines, smile lines, cheeks, temples, chin, and jawline. Bruising and swelling are common and last a few days. Immediate results are seen, however the full effect of filler is achieved two weeks after the treatment.

Microneedling restores the face’s collagen and elastin through a natural healing process, which improves skin quality and texture, acne scars, and pigmentation. Platelet-rich-plasma (PRP) involves using the patient’s own blood as a resource to isolate platelets, which contain growth factors and active proteins for tissue and injury healing. Microneedling can be used as the delivery method for PRP, which leads to exponential collagen production. Results are visible after one session, however 3-6 treatments, each 4-6 weeks apart, are recommended to optimize skin rejuvenation.

PRP (platelet-rich plasma) therapy for hair loss is a three-step medical treatment in which a person’s blood is drawn, processed through a centrifuge, and then injected into the scalp. PRP therapy requires three treatments 4-6 weeks apart. Maintenance treatments are required every 4-6 months.

Coolsculpting is an FDA-approved body contouring treatment that freezes and eliminates stubborn fat. It is non-invasive and requires no needles or downtime. Common treatment areas include the abdomen, flanks, thighs, arms, bra area, and submental area. Treatments take anywhere from 35-75 minutes. Two sessions are indicated for each treatment area (each one month apart) and optimal results are seen 12 weeks after each session.

Cooltone is an FDA-approved technology for toning, firming, and strengthening the abdomen, buttock, and thigh muscles. Cooltone’s Magnetic Muscle Stimulation, or MMS technology, penetrates through skin and fat layers to target the muscle layer, inducing involuntary contractions. The body’s responds to these contractions is to strengthen its muscle fibers, resulting in a more defined and toned appearance.
