Evangeline Lilly says starring in 'Lost' ruined her skin. The 29-year-old actress " who plays Kate Austen in the hit US TV show " admits she started surfing in the rough sea to cope with stress of filming, but the salty water soon took its toll on her complexion.

She said: "Last season of the show I surfed constantly, which was cathartic for me, but the sun and salt water wreaked havoc with my skin so, for the first time in my life, I had skin problems. I ended up wearing a full face of pink pure zinc to protect it. I looked ridiculous with this bright pink face but I just wanted to surf!"

Evangeline has also revealed the secret to her slim figure " indoor aerobics. She added to Britain's InStyle magazine: "I dance around my living room to cheesy 80s aerobics music until I'm sweating really hard! "I also walk a lot.

?Walking is a very underestimated exercise in North America. It's all run hard, lift weights and push your body, but walking is wonderful for elongating the body and posture."
