- Participants:
Fifty-six (56) male and female subjects ranging in age from 19 to 78 years of age. Fifty-two (52) subjects completed the study. The remaining subjects discontinued their participation for various reasons, none of which were related to the application of the test material.
Inclusion Criteria:
The following criteria applied to study participants: male and female, age 16 or older; an absence of any visible skin disease which might confuse the study results; prohibition on the use of topical or systemic steroids and/or antihistamines for at least seven days prior to study initiation; completion of medical history forms and informed consent forms; considered reliable and capable of following directions.
Exclusion Criteria:
The following applied: ill health; someone under a doctor's care and taking medication that might influence the outcome of the study; pregnant or nursing females; a history of adverse reactions to cosmetics or other personal care products.
