Brief summary: The purpose of this study is to evaluate the whitening potential effect of different mineral sunscreens across multi-cultural skin tones through instrumentation, imaging, and self-assessment and also evaluate the relationship between self-perception and objective measurement of whitening.


Eligibility criteria: Inclusion Criteria:

* Self-reported natural skin tone/skin color, targeting the following: skin tones "Pale/fair to light white" and "White to light beige" (n = 30 participants), skin tones "Beige to light tan/light olive" and "Medium tan/medium olive to light brown" (n = 30 participants), and Skin tones "Medium brown to dark brown" and "darkest brown to darkest black" (n = 30 participants)
* Has a history of using or is a current user of sunscreens
* Generally, in good health based on medical history reported by the participants
* Able to read, write, speak, and understand English
* Individual has signed the consent for photograph release and informed consent document (ICD) including Health Insurance Portability and Accountability Act (HIPAA) disclosure
* Intends to complete the study and is willing and able to follow all study instructions

Exclusion Criteria:

* Has known allergies or adverse reactions to common topical skincare products or ingredients in the ISMs
* Presents with a skin condition on the face, volar forearms, or lower legs that may confound the study results (example, psoriasis, eczema, atopic dermatitis, cutaneous xerosis, erythema, or active skin cancer) or interfere with evaluations (example, excessive hair, tattoos, scarring, very uneven skin tone, sunburn, scratches/broken/compromised skin)
* Has shaved or used any hair removal method on lower legs or volar forearms within 24 hours of Visit 1
* Has a history of a confirmed or suspected coronavirus disease 2019 (COVID-19) infection within 30 days prior to the study visit
* Within 14 days prior to Visit 1, has been in close contact (exposure within 6 feet for a cumulative time of 15 minutes or more over a 24-hour period) with anyone who has been infected with COVID-19
* Is under a COVID-19 isolation/quarantine order
* Has experienced any of the following self-reported symptoms of COVID-19 within 2 weeks prior to the study visit: unexplained cough, shortness of breath/difficulty breathing, fatigue, body aches (headaches, muscle pain, stomachaches), conjunctivitis, loss of smell, loss of taste, poor appetite, nausea, vomiting, diarrhea, palpitations, or chest pain/tightness; temperature greater than or equal to (\>=) 37.5 degrees celsius (C)/99.5 degrees fahrenheit (F), measured; use of fever or pain reducers within 2 days prior to the study visit
* 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: Immunosuppressive or steroidal drugs within 2 months before Visit 1; non-steroidal anti-inflammatory drugs within 5 days before Visit 1; antihistamines within 1 week before Visit 1
* Is self-reported to be pregnant or planning to become pregnant during the study
* 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
* Is simultaneously participating in any other clinical study or has participated in any product-use study within 14 days prior to Visit 1
* Is an employee/contractor or immediate family member of the principle investigator (PI), study site, or sponsor
