Cosmeceuticals: Active Skin Treatment
Cosmeticals: Active Skin Treatment, which now features several new chapters from industry leaders. The additional sections focus on areas such as formulating for sensitive skin, amphoteric hydroxyl complexes, pollution and aging, whitening efficacy, and substantiating antiaging product claims. The term "cosmeticeutical" has been surrounded by controversy, as some chapters in this book explain. Mostly, the debate circles around issues of consumer protection, product safety and industry responsibility, with the main question being, "How much activity can a product claim or deliver without changing from a cosmetic to a pharmaceutical product?" Industry authorities put forth their arguments for whether or not a separate category is useful or necessary, and the FDA's position regarding "active" cosmetics is explained. Obviously, the personal care industry is interested in avoiding falling under drug regulations whenever possible because of the added costs and complications. This book covers a wide range of regulatory and formulating topics within the area of active cosmetics. Besides the discussions into the anticellulite efficacy of various actives, this book includes excellent reviews on ceramides and hyaluronic acid as skin-care ingredients as well as a summary of the role of application frequency in drug dosing, tackling the question of whether one larger dose or three smaller doses (adding up to the same total dose) will deliver more of the active on the skin. Other chapters cover an efficient scheme for formulating treatment products, formulating for sensitive skin, sensitivity in ethnic skin types and the special care considerations for formulators need to be aware of for infant and elderly skin.
