National Geographic and four women went to four most extreme corners of the earth to put their skin to the test.

Many people rather test out a prestige skincare product before they spend their hard-earned money on it. Well, these four brave women took the absolute far out test! In a new series of short vignettes (view teaser video here) by SK-II with National Geographic, four celebrities from around the world traveled to some of the most extreme and beautiful places on earth. They actually put themselves and their skin to the test with Facial Treatment Essence. What’s special about this facial essence, is that it contains more than 90% Pitera, which is a clear liquid that’s rich in vitamins, amino acids, minerals and organic acids. This miracle liquid was discovered more 35 years ago in Japan that helps deliver beautiful, crystal clear skin, diminish wrinkles and improve firmness.

The series, which launches today, comprises of four riveting short compositions following the unique adventures of four loyal SK-II users and female celebs, as they subject their skin to the perils of some of the world’s toughest environments from the Yanbaru jungle in Okinawa, Japan to the Anza Borrego Desert in America.

• Chiara Ferragni, global fashion icon
• Kasumi Arimura, award winning Japanese actress
• Nini, celebrated Chinese actress

The Proof of Pitera™

SK-II Facial Treatment Essence is made up of over 90% Pitera™, a natural bio-ingredient containing vitamins, amino acids, and minerals. Pitera™ helps skin retain its natural functions, so your skin stays Crystal Clear. With over 50 micro-nutrients, the signature ingredient Pitera™ conditions skin and helps soothe skin surface concerns that can be caused by a range external aggressors such as harsh UV and pollution. When conditioned by Pitera™, skin is also able to lock moisture from within over time to overcome dryness, which can be caused by exposure to extreme hot and dry as well as cold and dry conditions.

“We continue to discover new miracles of Pitera™ and especially its ability to maintain Crystal Clear Skin no matter what condition you are in. We have teamed up with National Geographic to bring four of our SK-II loyal users and celebrities on grueling expeditions to some of the most extreme environments on earth to pit their skin against the harsh elements. We hope this groundbreaking campaign will inspire women with the confidence to see the world with no constraints and experience the transformative power of Crystal Clear Skin.”- Sandeep Seth, Marketing Director, Global SK-II

“National Geographic embodies a relentless pursuit to go further, to push boundaries, and to be pioneering in everything we do. Therefore there was no better partner for SKII in completing the Face the Wild, Face the Camera Extreme Expedition series. We are pleased to have provided guidance and in-field expertise for these series of vignettes to some of the most extreme places on earth.” –Yamini Ashish, Senior Vice President of Advertising Sales & Partnerships, FOX Networks Group, APAC and Middle East
