A new poll has claimed that most women believe that they look five years younger until they hit the age of 45.
According to the poll, eight out of ten women felt that born with good genes was the crucial factor in staying looking youthful, the Daily Express reported.
Three-quarters believed that they looked five years younger because of the quality of their skin and one in 10 was under the impression that they looked a whole decade younger.
The poll was conducted for Lancome Advanced Genefique, whose spokeswoman Victoria Campbell said there was no reason women shouldn't go on enjoying their looks well into their seventies.
Women believed that a happy marriage, avoiding sunburn, using a good moisturizer or serum, eating fruit and vegetables and a glass of wine at the weekend were among the "secrets of eternal youth".
