And the biggest compliment you can pay women over 35 is...

According to a new survey, the biggest compliment one can pay to a woman over 35 years of age is to tell her that she looks young rather than slim with 60% of women admitting this gives them the biggest confidence boost.

Youthful, glowing skin is something that women are constantly striving for and this is the reason why one in three women feel pressure to look young, says a survey.

New research from cosmetic brand Sanctuary Spa Wonder Oil Serum found that women feel pressure to look young and this is the reason why two-thirds of British women now use anti-ageing products, reports femalefirst.co.uk.

The survey says the biggest compliment one can still pay to a woman over 35 is to tell her that she looks young rather than slim with 60% of women admitting this gives them the biggest confidence boost.

The research also found that one in five women worry about how old they look every day with 10% admitting to thinking about it several times each day.

"In my job, I see far too many women lacking confidence in their appearance because of societal pressures,” said celebrity facialist and Sanctuary Spa skincare expert, Nichola Joss.

Also the research says that women are their own harshest critics earlier on in life, with one in five under the age of 24 believing they look older than they actually are compared to just 7% who are over 55.

"Wrinkles will befall us all and there are products which provide a visible improvement in the skin's appearance, but ultimately, the idea that growing older is bad has to stop,” said Joss.
