The time women spend putting on make up and getting dressed works out at 3,276 hours over their lifetimes while men only devote 1,092 hours to looking their best.
A survey of 1,000 women also showed that 67 per cent thought that the time spent getting ready was actually a chore.
Only a third of women said they enjoyed preening themselves.
They spend about half an hour washing and styling their hair followed by 20 minutes applying make-up and 15 minutes applying nail varnish.
And there is evidence of a north south divide. Two thirds of northern women spend an average of 146 minutes getting ready compared with southerners who take 117 minutes to pamper themselves.
Women in the north also like to go out more with 71 per cent saying they go out twice on a weekend compared with 49 per cent in the south.
Heather Boden from Skinbliss, who commissioned the research, said: "The figures come as no surprise considering the pressure that today's women are under just to make themselves look good.
"There's a host of waxing, exfoliating, moisturising, straightening, polishing and plucking involved in getting ready for a night out. When you're stretched for time or just simply want to get out, see your friends and have a good time, the routine of getting ready can often be an unwanted task."
