About

This is a single-site, non-randomized, non-controlled study at UT Southwestern Medical Center at Dallas in the Department of Plastic Surgery designed to follow up to 30 qualified and consenting subjects receiving a fractionated 1927 combination treatments for diffuse hyperpigmentation and/or melasma. Patients will receive treatment using f1927 devices and will be treated twice over the affected areas, once each month for a total of two months, followed by two follow-up visits at 1-month and 3-months post-treatment.

Full description

This is a prospective, non-controlled study where subjects will receive treatment using f1927 devices and will be treated twice over the affected areas of the face once each month for a total of two months. Patients will be evaluated at 1-month and 3-months post-treatment to monitor the clinical effects of treatment. Overall assessment of treatment efficacy will be based on evaluation of standard and close-up photography using pre- and post-procedural photos as well as images obtained by the Vectra H2 3D Imaging System. Baseline changes in the visualization and numeric analysis of pigmented areas will be evaluated utilizing the 3D Facial Skin Analysis software on the H2 System. Subjects will also undergo non-invasive skin measurements using optical coherence tomography (OCT) to noninvasively gather topographical and histological images of pre- and post-treated skin. Screening, treatment(s) with f1927, and OCT measurements are all for research purposes.

Women of childbearing potential must have a negative urine pregnancy test and must not be lactating at Screening. Women must be willing and able to use an acceptable method of birth control (see below) during the study. Women will not be considered of childbearing potential if one of the following is documented - postmenopausal for at least 12 months prior to study, without a uterus and/or both ovaries, bilateral tubal ligation at least 6 months prior to study enrollment
Individuals of childbearing potential who use an acceptable method of contraception throughout the study. Acceptable methods of birth control include:
- Established use of hormonal contraception (oral, injected, implanted, patch or vaginal ring)
- Barrier methods with spermicide: condom or occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/suppository
- Intrauterine device (IUD) or intrauterine system (IUS)
- Surgical sterilization (e.g. vasectomy confirmed to be effective by sperm count check, tubal occlusion, hysterectomy, bilateral salpingectomy/oophorectomy)
- Abstinence from heterosexual intercourse, when this is in line with the preferred and usual lifestyle of the subject. Periodic abstinence (e.g. calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal methods are not acceptable forms of contraception
Individuals who can read, speak, write and understand English and who are willing to provide written informed consent.

Individuals with skin pathology and/or pre-existing dermatologic condition in the treatment area (i.e. psoriasis, rosacea, eczema, seborrheic dermatitis, vitiligo, hyper or hypo-skin pigmentation conditions such as post inflammatory hyperpigmentation) that the Investigator deems inappropriate for participation or could interfere with outcomes of the study.
History of chronic drug or alcohol use.

- Neurotoxins within the past week
- Ablative resurfacing laser treatment within the past 6 months
- Non-ablative, rejuvenative laser or light treatment within the past 6 months
