Women start fretting about the effects of ageing at the 'grand' age of 28, shows a new research.
After spending most of their time in front of the mirror trying to look older, girls finally become happy with their appearance in their early 20s.
But the Olay Regenerist poll of 4,000 women pinpointed 28 - the age of supermodel Gisele Bundchen - as when they start to worry.
And 16 per cent began to get concerned at just 20.
The poll found girls spend on average 216 pounds a year on anti-ageing treatments.
"Girls want to make sure they stay looking young from an early age," The Sun quoted spokeswoman Sarah Clarke, as saying.
