Emily Rekstis from New Beauty recently contacted us with a solitary question: What is one skin care tip we would recommend for everyone, despite age, gender, or skin type? The answer is so simple, but often neglected. See the complete article here.

Jane Fonda is an ageless beauty icon. So when her makeup artist, Shawnelle Prestidge, spoke with W about how the actress keeps her skin youthful , we couldn’t resist checking out Fonda's tricks.

There was one tip in particular that stood out as a good rule to follow when it comes to finding the best anti-aging products for anyone: hydration. "I was always after products that would hydrate to a noticeable degree," Prestidge said.

However, Prestidge noted that most products available were full of nonorganic ingredients and synthetic fragrances. After some encouragement from Fonda, Prestidge decided to create her Ageless Skin Serum ($125), one of the five hero products of her Prestidge Beauté Active Organics line. "The aesthetician in me was very passionate and unconsciously on a mission to create what has come to be my hero product."
