Beauty Science Book

P&G Beauty believes that science education is the key to helping physicians, cosmetologists, consumers and students understand how and why beauty products provide real results. The Beauty Science Book provides in-depth basic scientific understanding about hair and skin biology and chemistry, focusing on skin anti-aging, skin tone evenness, hair color and dandruff prevention.

Skin Tone

In the age-old quest to retain youthful beauty, reducing wrinkles and fine lines has often overshadowed maintaining even-toned skin. But a glance at art across cultures and centuries shows that luminous, even skin tone is considered ideal. From the palest white powders used by Japanese courtesans to the bronzers applied by women of today looking for even, sun-kissed color without the risk of tanning - changing skin tone to enhance beauty has been an ongoing interest of women for hundreds of years. In recent years, medical science has offered pharmacological tools to help with pigmentation changes due to natural aging, photo damage or skin conditions, and many of these tools and understandings are now being reapplied to the world of cosmetics. Still, the connection between skin tone, skin health and perception of age is only beginning to be illuminated. Read more »

Anti-aging - Fine Lines & Wrinkles

The appearance of fine lines and wrinkles is one of the most common signs of aging in people around the world. Yet, regardless of when wrinkles are first noticed, they are an unwelcome indicator of age, especially for women who are leading more active lives and are looking for ways to look and feel their best. Increased life expectancy has changed the concept of aging and, in turn, propelled anti-aging research that has led to a multitude of topical applications. Skin science is advancing at an exponential pace, yet profound gaps remain in patients' understanding of the biological mechanisms of skin and the research supporting interventions that can help to preserve supple, smooth, youthful skin and nourish, replenish and renew aging skin.

Hair Color

Beyond its biological function of keeping the head protected and warm, hair's true value lies in its ability to make a highly personal, visual statement about oneself. Throughout history, hair color has defined cultures, social status, professions, age and self-image; so when humans discovered ways to change hair color, it signified a major step in self-expression. This self expression, however, has always been influenced by innovative science. Read more »


Recent genetic research into this all-too-common scalp irritant has turned up new evidence that the fungus causing the problem is not what it first appeared to be. Formerly identified as Pityrosporum ovale, an antiquated term that is no longer used, and later misidentified as Malassezia furfur, the fungus producing seborrheic dermatitis/dandruff actually belongs to a sister species and is not M. furfur. Using genome-based methodology, researchers at P&G Beauty collared the true culprit, Malassezia globosa. More importantly, in making a clearer identification, they uncovered the fungus' mode of operation and documented the cycle that causes excessive scalp desquamation. P&G Beauty's pioneering work corrects decades of guessing and inaccurate attribution. Read more »
