Abstract:
Acquiring or maintaining healthy skin requires a multifunctional approach: mild cleansing, moisturizing, and sun protection. The clinical benefits of a daily, healthy facial skin-care regimen comprising a mild cleanser and moisturizer were evaluated on normal skin, self-perceived sensitive skin, and dermatologist-assessed sensitive skin for a period of up to 4 weeks. Subjects with normal, healthy skin were photographed with a calibrated, high-resolution digital camera, and the average improvement in overall health was calculated using image morphing and facial averaging techniques, following a 2-week period of product application. In a second study that included subjects with self-assessed sensitive facial skin, changes in skin hydration, skin dryness, and skin sensitivity (determined by means of a lactic acid sting test and subject self-assessment) were monitored during a 3-week regimen of mild cleansing and moisturizing with products designed for sensitive skin. The third study involved dermatologist-assessed highly sensitive skin patients (mostly rosacea with an atopic background in some cases). These patients underwent a 4-week skin-care regimen involving mild cleansing and moisturizing. In all three studies, significant improvements in skin health/quality were observed by means of expert assessments, instrumental evaluations, and subjective self-assessment.
