Antiaging Breakthrough No. 6: Antiaging Sunscreens
Among the most exciting new ways to fight skin aging are two dramatic breakthroughs in sun protection: Helioplex, a new technology that makes current sunscreen ingredients more effective, and Mexoryl SX (ecamsule), a new protective agent. Representing the first innovation in skin sun protection in more than 20 years, each is specifically designed to defend against the aging effects of short UVA rays.
"They are truly the best we have, and they are a major, major advance in terms of antiaging protection," says Katz.
Most of us know about the dangers of burning UVB rays, but you might be less aware of the damaging and aging effects of UVA. "These are the ones that go deep -- UVA rays cause the deep collagen and elastin damage that contributes to aging skin," says Katz.
While most sunscreens effectively protect against UVB rays, protection from UVA was mostly limited to the "long" waves, with ingredients that were unstable and frequently degraded in the sun.
But Mexoryl SX (ecamsule), a UVA-blocking sunscreen developed by L’Oreal, and Helioplex, a technology created by Neutrogena to stabilize traditional sunscreen ingredients avobenzone and oxybenzone, are proving not only to protect against the damaging short UVA rays, but to offer long-lasting protection without the need to constantly reapply.
"They have been available in Europe for some time now, and there is no question they work -- and from an antiaging standpoint, they can be your best friend," says Goldberg.
Even more exciting: In 2007 these sunscreen advances were combined with antioxidants and other antiaging ingredients in moisturizers and day creams that offer Fort Knox-level protection against the aging effects of the sun.
