Brief summary

The purpose of this study is to compare the investigational medical grade laser device to a marketed medical grade laser device for effectiveness in lightening or clearing unwanted tattoos. This study will also compare any side effects from treatment with the devices.

Detailed description

This is a two center study to evaluate the Cutera RF system. Subjects will be treated on the abdomen and / or flanks areas and / or saddle bag (upper lateral thigh, lateral hip and lower buttocks). The objective of this study is to evaluate the thermal and histological changes observed in the subcutaneous tissue following RF exposure.

Exclusion criteria

* Participation in a study of another device or drug within 6 months prior to enrollment or during the study * Prior treatment for tattoo removal in the target area, e.g., with q-switched laser, IPL, dermabrasion, electrocautery, cryotherapy * History of allergic reaction to pigments following tattooing * Presence of double tattoo in the treatment area * History of allergy to local anesthetics * History of allergy to topical antibiotics * History of malignant tumors in the target area * Skin abnormalities in the target area, e.g., cuts, scrapes, wounds, scars, large moles * Pregnant and/or breastfeeding * Having an infection, dermatitis or a rash in the treatment area * Significant concurrent illness, such as diabetes mellitus or cardiovascular disease, e.g., uncontrolled hypertension * Suffering from coagulation disorders or taking prescription anticoagulation medications * History of keloid scarring, hypertrophic scarring or of abnormal wound healing * History of immunosuppression/immune deficiency disorders or currently using immunosuppressive medications * History of vitiligo, eczema, or psoriasis * History of connective tissue disease, such as systemic lupus erythematosus or scleroderma * History of seizure disorders due to light * Any use of medication that is known to increase sensitivity to light, such as tetracycline * History of herpes simplex and/or herpes zoster (shingles) * History of radiation to the treatment area or undergoing systemic chemotherapy for the treatment of cancer * History of pigmentary disorders, particularly tendency for hyper- or hypo-pigmentation * Systemic use of corticosteroid within 12 months of study participation * Use of oral isotretinoin within 12 months of study participation and topical use of isotretinoin within 6 months on the treated area * Anytime in life, having have used gold therapy (gold salts) for disorders such as rheumatologic disease or lupus * Excessively tanned in areas to be treated or unable/unlikely to refrain from tanning during the study * Current smoker or history of smoking within 6 months of study participation * As per the Investigator's discretion, any physical or mental condition which might make it unsafe for the subject to participate in this study
