Ageing Starts At 29! Are You Ready? Here's What You Need to Know

There is a magic number that many skincare experts agree upon as the time that a person starts ageing. “The ageing process starts around 29,” Joanna Czech, the esthetician behind Cate Blanchett, Kate Winslet, and Christy Turlington’s skin told us. That number surprised even us, so we asked a variety of other experts—Renee Rouleau, Dr. Harold Lancer—and, even more shockingly, we got the same answer. “That’s about the age that collagen fibres start losing their elasticity,” Czech says.

It turns out, 29 is the generally-accepted number that marks the beginning of the ageing process. Of course, lifestyle and genetics, as well as diet and sun protection, can change everything—and so can a good skincare routine.
