Principles of Moisturizer Product Design

: Moisturizers provide significant benefit in dermatology – as adjuvant therapy for many clinical conditions, as a key player in anti-aging regimens, and as a core component in maintaining healthy skin barrier function.

In fact, moisturizer design today has become an art as well as a science. Product efficacy, aesthetics, and packaging are all engineered in a variety of ways, to create an expansive market of products that meet many consumer needs.
