A Study to Evaluate the Ability of Sunscreen Products to Modulate the Effects of Deep UVA +/- HEV Blue Light Induced Pigmentation and Biomarkers of Cutaneous Oxidative Stress

Completed · Not applicable

Conditions studied: Pigmentation, Oxidative Stress

In brief

To assess the level of sub pigmentation following an acute exposure to a Deep Ultraviolet A and high energy Blue Light wavelengths (380-420 nm). This study will compare the unprotected control with test products in Condition #1 and Condition #2 to assess pigmentation as well as cutaneous oxidative stress and inflammation biomarkers that occur with exposure to the same light regimen.

Has a history of abnormal responses to sunlight or UV radiation.
Has been instructed by a physician, pharmacist, or health professional to avoid sunlight because of a medical condition and/or because of drug contraindications.
Has a history of photosensitivity (a reaction to sunlight) disorders (including solar urticaria [hives], phototoxicity, photo-allergy, polymorphous light eruptions).
Is regularly taking a medication with photosensitizing potential, such as high blood pressure medication, acne medications (e.g., Accutane), certain psychiatric medications (e.g., Thorazine, tricyclic anti-depressants), certain antibiotics (e.g., Cipro, tetracycline), antihistamines (e.g., Benadryl), Levulan, or Psoralen.
Is regularly taking other medication that could affect the results of the study (e.g., corticosteroids, steroidal or nonsteroidal anti-inflammatory drugs [NSAIDs], antihypertensive drugs, steroid inhalers, drugs that induce skin coloring, etc.). Low dose aspirin (≤81mg per day) is acceptable.
Has used a tanning bed/lamp, has had extended sun exposure of the test area (the lower back), or has participated in a UV exposure study within 4 weeks before Visit 1.
Has a concurrent illness, a medical history of a disease/condition, or a pre-existing/dormant dermatologic condition (e.g., psoriasis, rashes, eczema, seborrheic, severe excoriations, skin infection [fungal, bacterial, or viral], etc.) that could interfere with the outcome of the study or increase health risk to the subject, as determined by the PI or designee.
Via visible light and Wood's lamp evaluation: presence of sunburn, suntan, scars, tattoos, active dermal lesions, nevi, blemishes, moles, excessive tan spots from prior sunscreen testing, excessive hair, or uneven skin tone on the test area (back) that might interfere with the study.
Has a history of immunosuppression/immune deficiency disorders (including HIV infection, AIDS, multiple sclerosis, Crohn's disease, rheumatoid arthritis), organ transplant (heart, kidney, etc.), and/or undergoing radiation or chemotherapy as determined by study documentation.
Has self-reported Type 1 or Type 2 diabetes or is taking insulin or another anti-diabetic medication.
Is taking a medication that would mask an Adverse Event (AE) or confound the study results, including:
Non-steroidal anti-inflammatory drugs within 5 days before Visit 1.*
Antihistamines within 14 days before Visit 1.*
Antibiotics within 16 days prior to Visit 1.*
Immunosuppressive drugs or steroidal drugs within 2 months before Visit 1.*
Systemic or topical medication that is known to alter responses to UV radiation.* * If an individual is taking one of these medication types, the individual is not considered eligible at screening. However, if a subject begins using one of these medications during the study, the PI should be consulted to consider the impact of the specific medication on subject safety and/or the study results.
Has a personal or family history of skin cancer.
Has skeletal protrusions and/or extreme areas of curvature in the test area.
Is self-reported to be pregnant, lactating, or planning to become pregnant during the study or within 30 days of study completion.
Has a history of or a concurrent health/other condition/situation which may put the individual at significant risk, confound the study results, or interfere significantly with the individual's participation in the study .
Has shaved, waxed, and/or used any hair removal method on the test area (back) within 2 weeks before visit 1.
