Brief Summary

The purpose of this study is to determine the static SPF of three sunscreen products (ChapStick Active Performance \[CAP\] UnScented, CAP Herbal Mint and CAP Mountain Berry) using the methodology described in the Food and Drug Administration (FDA) Final Rule (2011).

Outcome Measures

Primary Outcomes (1)

• Arithmetic Mean SPF Values

  SPF values for each test product and the SPF standard were first calculated for each individual participant:SPFi = MEDp/MEDuR (p=protected \[treated\] site; u=unprotected \[untreated\] site). The arithmetic mean SPF, standard deviation (SD) and standard error (SE) were then calculated separately for each test product and the SPF standard from valid SPFi data: SPF = (ΣSPFi)/n; SD = √\[(ΣSPFi\^2) - ((ΣSPFi)\^2/n) /(n-1))\]; SE = SD/√n (n = number participants providing valid test results). For SPF determination to be considered valid, in compliance with FDA Final Rule 2011, the mean SPF value of the SPF standard should fall within the SD range of the expected SPF (i.e.,16.3 ± 3.43 or 12.87 to 19.73). The MED is the lowest dose of UV radiation that produces the first perceptible erythema with clearly defined borders (covering more than 50% of the exposure site), 16 to 24 hours (hrs) after UV exposure administration.

  From 16 to 24 hours post UV exposure

Study Arms (4)

CAP UnScented

EXPERIMENTAL

Single topical application: 80 +/- 2 milligrams (mg) (2.0 +/- 0.05 mg per square centimeter \[mg/cm\^2\]) of CAP UnScented will be applied to the assigned test site using a fingercot. Test material will be evenly spread over the test site using light pressure for 35 +/- 15 seconds.

Drug: CAP UnScented

CAP Herbal Mint

EXPERIMENTAL

Single topical application: 80 +/- 2 mg (2.0 +/- 0.05 mg/cm\^2) of CAP Herbal Mint will be applied to the assigned test site using a fingercot. Test material will be evenly spread over the test site using light pressure for 35 +/- 15 seconds.

Drug: CAP Herbal Mint

CAP Mountain Berry

EXPERIMENTAL

Single topical application: 80 +/- 2 mg (2.0 +/- 0.05 mg/cm\^2) of CAP Mountain Berry will be applied to the assigned test site using a fingercot. Test material will be evenly spread over the test site using light pressure for 35 +/- 15 seconds.

Drug: CAP Mountain Berry

SPF Standard

ACTIVE COMPARATOR

Single topical application: 80 +/- 2 mg (2.0 +/- 0.05 mg/cm\^2) of SPF Standard will be applied to the assigned test site using a fingercot. Test material will be evenly spread over the test site using light pressure for 35 +/- 15 seconds.

Drug: SPF Standard Sunscreen

Eligibility Criteria

• Age: 18 Years - 70 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Participant must provide a signed and dated, legally effective, informed consent document, which indicates they have been informed of all pertinent aspects of the study, before any study procedures are performed.
• Participant must provide relevant details of their medical history and current/recent medications and treatments (self-reported).
• Participant must have completed an annual Health Insurance Portability and Accountability Act (HIPAA) Authorization form.
• Participant must have completed a Photo Release Form.
• Participant must be able to read, write, speak and understand English.
• Participant must be in good general health.
• Participant must have uniform skin color over the test area (skin of the back between the shoulder blades and above the waistline) and an Individual Typology Angle (ITA) value greater than (\>)28 degree.
• Participant must have Fitzpatrick Skin Type I, II or III
• Participant must have sufficient area of suitable skin on their back for at least six 40 square centimeter (cm\^2) test sites.
• Willing to have body hair clipped by a technician if participant has excessive hair in the test area.
• Participant must have a valid form of personal identification (photo identity \[ID\], driver's license, passport, permanent resident card, military ID card; forms cannot be expired).
• Male and female participants of child-bearing potential must agree to use a highly effective method of contraception for the duration of the study and for 14 days after their last treatment application. (Note: A participant is considered to be of child-bearing potential if, in the opinion of the principle Investigator \[PI\], they are biologically capable of having children and sexually active.

You may not qualify if:

• Participant with a scheduled or planned Covid-19 vaccination during likely dates of study participation.
• Participant with a history of abnormal response to sunlight/UV radiation.
• Participant with a history of sensitivity to any ingredient of the test material or skin marker pen, or to latex; or any known sensitivities/allergies, including but not limited to cosmetic/toiletry products and topically applied skin treatment products/drugs.
• Participant with any significant dermatological condition, such as atopic dermatitis (eczema), psoriasis, skin cancer, melanoma, active dermal lesions, nevi, blemishes or moles, lupus, diabetes, or connective tissue disease, that would increase the risk associated with participation. (Note: presence of non-dysplastic nevi, blemishes, or moles would be acceptable if, in the opinion of the PI, they will neither jeopardize participant safety or compromise study outcomes. A participant with dysplastic nevi should be disqualified.
• Participant receiving any treatment with medications that would, in the opinion of the PI, confound study outcomes or increase the risk associated with participation, such as systemic or topical corticosteroids, antibiotics, anti- inflammatory drugs, antihistamines, antihypertension medications, or any other photosensitive medications. (Note: The prohibited medication list will be available to site staff for reference during screening).
• Participant who has used topical or systemic steroids, antihistamines, antibiotics or anti-inflammatory medications within 7 days of Study Day 1 which, in the opinion of the PI, could interfere with study outcomes.
• Participant who has used/applied any personal care products (for example, lotions, sunscreens, sunless tanners) and/or topical medications in/on the test area within 24 hours (hrs) of Study Day 1.
• Participant who is unwilling to cease use of personal care products (for example, lotions, sunscreens, sunless tanners) and/or topical medications in/on the test area for the duration of the study.
• Participant with any known communicable disease(s) (for example, Human Immunodeficiency Virus \[HIV\], Sexually Transmitted Diseases \[STD's\], Hepatitis B, Hepatitis C, and so on).
• Participant with skeletal protrusions and/or extreme areas of curvature in the test area.
• Participant with a medical treatment/vaccination (other than the Covid-19 vaccination) planned during the study, which would make them ineligible, place them at undue risk, or confound the outcome of the study, per the discretion of the PI.
• Participant who has undergone any surgical procedure in the last 12 months.
• Participant who has undergone chemical or physical treatment procedures in the test area within the last 12 months.
• Planned hospitalization during the study.
• Participant who exceeds a weight limit of 300 pounds due to equipment limitations.
