Sunscreen
Conditions
Brief summary
The purpose of the study is to evaluate the whitening potential of different mineral and chemical sunscreens across multi-cultural skin tones through instrumentation, imaging, and self-assessment. It also aimed to evaluate the relationship between self-perception and objective measurements of whitening.
Interventions

Exclusion criteria
* Has known allergies or adverse reactions to common topical skincare products or ingredients in the IPs * Presents with a skin condition and/or pre-existing or dormant dermatologic disease on the face, volar forearms, or lower legs that may confound the study results (e.g., psoriasis, eczema, atopic dermatitis, cutaneous xerosis, erythema, or active skin cancer, rosacea, moderate to severe acne, acne conglobate, nodules, and/or cysts on the face) or interfere with evaluations (e.g., excessive hair, tattoos, scarring, nevi, very uneven skin tone, sunburn, scratches/broken/compromised skin) * Has had any facial treatments including facials, facial peels, photo facials, laser treatments, dermabrasion, botulinum toxin (Botox), injectable filler treatments, intense pulsed light (IPL), acid treatments, tightening treatments, facial plastic surgery, or any other treatment administered by a physician or skin care professional designed to improve the appearance or firmness of facial skin withing 30 days prior to Visit 1 * Has shaved or used any hair removal method on lower legs or volar forearms within 24 hours of Visit 1 * Has a history of skin cancer within the past 5 years * 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 confuse the study results * 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 a disease such as asthma, epilepsy, hypertension, hyperthyroidism, or hypothyroidism that is not controlled by diet or medication. Individuals having multiple health conditions may be excluded from participation even if the conditions are controlled by diet, medication, etc. * Is self-reported to be breast feeding, 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, confuse the study results, or interfere significantly with the individual's participation in the study * Has started any long-term medication within the last 2 months * Is simultaneously participating in any other clinical study or has participated in any product-use study within 30 days prior to Visit 1 * Is an employee/contractor or immediate family member of the PI, Study Site, or Sponsor
