ABSTRACT

The formulation of skin care products requires a cross-disciplinary knowledge base, which

can be difficult to obtain. How can any individual obtain the knowledge of a dermatologist,

the expertise of a PhD biochemist, the experience of a cosmetic chemist, and the insight of

a research and development scientist? There is not enough time in one lifetime to master

all of these disciplines. It takes eight years after college to become a dermatologist, at least

five years to obtain a PhD, 10 years to become an experienced cosmetic chemist, and

10 years to mature into a research and development scientist. Thus, after 33 years of work

experience and schooling the cross-disciplinary knowledge base would be complete! This

text aims to condense 33 years into 400 pages, allowing mastery of the field of skin care

formulation by the exchange of knowledge.
