Study Design Characteristics:
- Allocation: None
- Intervention Model: SINGLE_GROUP
- Observational Model: None
- Primary Purpose: PREVENTION
- Time Perspective: None
- Masking: NONE
- Phase: None
- Number of Arms: 1.0

Eligibility Criteria:
Inclusion Criteria:~* Healthy individuals 18 years of age or older.~* Individuals with mild, moderate, or severe photodamage \[1\] of the skin on the forearms (also Appendix C) and Fitzpatrick skin type II or III (21 CFR 352.72).~* Females of childbearing potential will need to undergo a pregnancy test at the enrollment visit, after administration of the informed consent form (ICF) and before exposure to SSL. Premenopausal female subjects must use an effective method of birth control (such as oral contraceptives, consistent use of barrier contraceptives, intrauterine device (IUD), or other proven method of birth control) during study participation. For the purposes of this study, a woman will be considered postmenopausal if any of the following criteria are met: (1) she has had prior bilateral oophorectomy; (2) she is over the age of 60 years; or (3) she is under the age of 60 years and has not had a menstrual period in 12 or more months in the absence of chemotherapy, tamoxifen, toremifene, or ovarian suppression.~* Individuals who are willing to limit sun exposure to the body during the study period and who agree to wear protective clothing when they are outdoors.~* Individuals who have the ability to understand and willingness to sign an informed consent before initiation of study procedures, after the nature of the study is explained to them and they have had the opportunity to ask any questions.~Exclusion Criteria:~* Individuals with any inflammation or irritation of the skin at the test areas, or any skin conditions felt by the study medical provider to contraindicate enrollment. This includes, but is not limited to, psoriasis or atopic dermatitis within the test areas.~* Test area is defined as the 6 mm areas of skin that is exposed to SSL and will be biopsied.~* Individuals with a history of any untreated skin cancer, melanocytic lesions, or actinic keratoses in the test areas are ineligible. History of such conditions at a body site other than the test areas is not exclusionary if in the opinion of the study medical provider it will not pose a risk to the subject.~* Individuals who have had invasive cancer, chemotherapy or radiation therapy within five years of study enrollment~* Individuals who are immunosuppressed by virtue of medication or disease. This includes AIDS patients, subjects taking oral steroids, and subjects on immunosuppressants/immunomodulators (cyclosporine, chemotherapeutic agents, or biologic therapy), as determined by the examining study medical provider.~* Individuals with serious intercurrent illness including, but not limited to, ongoing or active infection, psychiatric illness, or other situations that in the opinion of the examining study medical provider would limit compliance or interfere with the study regimen.~* Individuals who have used photosensitizing drugs (see Appendix for examples) within 30 days of enrollment, or who will be using a photosensitizing drug during the time of the study, will not be eligible. Subjects may be reconsidered for eligibility 30 days after the last dose of such medications.~* Individuals who have used any topical medication other than emollients or sunscreen/sunblock on the test area within 30 days prior to study enrollment. If a study participant requires topical medication to the test area during the study, they will be withdrawn from the study.~* Individuals who have used retinoids, steroids, 5-fluorouracil, Levulan, Vaniqua (eflornithine), Solaraze, or Imiquimod (Aldara®) anywhere on the body within 30 days prior to study enrollment. Subjects may be reconsidered for eligibility 30 days after the last topical treatment with such medications.~* Individuals must not take mega-doses of vitamins. Mega-doses are defined as more than 5 capsules of standard multivitamins daily or more than the Tolerable Upper Intake Levels of Vitamins, as defined by the Institute of Medicine, National Academy of Sciences. Such vitamin therapy must be discontinued at least 30 days prior to study entry.~* Individuals with a history of deliberate natural or artificial sun exposure (tanning) within 30 days of study enrollment are not eligible.~* Individuals with Fitzpatrick skin type I are ineligible, as the proposed SSL dose could result in a burn of greater than mild severity.~* Individuals with Fitzpatrick skin type IV, V or VI are ineligible, as they are unlikely to exhibit a salient response in the proposed design.~* Individuals currently enrolled in or who plan to enroll in another clinical trial. There must be a 30-day period between completing a previous study and enrolling in this study.~* Individuals with a known allergy to lidocaine are not eligible.~* Females who are pregnant or nursing.

Study Arms:
- TLR4 and TOPK/PRPK Signaling in Sun Damaged Human Skin Acutely Exposed to Solar Simulated Light (Type: EXPERIMENTAL): We have one arm, which consists of participants with a broad range of sun damage on the forearm. Based on the standardized clinical photodamage scale (Hu C, Curiel-Lewandrowski C. Archives of Dermatology, 2011; 147(1):31-36), we will include mild (N=12), moderate (N=12), and severely (N=12) sun damaged skin.

Based on this trial design, predict the completion outcome and termination type (if applicable).
