Gender Matters in Skin Care Testing (Brief) 

Nava Dayan, Dr. Nava Dayan LLC  09.01.17

Gender differences exist and should be acknowledged and considered in nature, in life, in our work practice and in our communication to consumers. Each study design requires customization when considering the product tested, its components, vehicle and other properties. When conducting an in vitro or in vivo study, key considerations related to gender and gender-age criteria should be weighted for safety and efficacy. Females are profoundly affected by hormonal state, therefore their hormonal state should be examined, considered and documented. It is important to understand their cycle in relation to study endpoint time table collection, their age related hormonal status especially during peri-menopause and menopause. In addition, a thorough baseline should be collected from all individuals that include pH, TEWL and others measures that may be relevant to the study objective.
