A new study by a self-tanning lotion called St. Tropez has figured out exactly when women look their oldest:  It’s at 3:30 on Wednesday afternoon.  Here’s why:

1.  46% of women drink over the weekend, and your body needs to break down all the toxins and sugars you take in . . . which puts a strain on your body.  Only, the effects of that strain can take up to 72 hours to show up on your face.

2.  37% of women say that they don’t get a good night’s sleep on Monday.  And that takes 48 hours to show up on their face.

3.  Monday is also the day women are most likely to forget to use their skin-care products.

4.  Finally, one in eight women say Wednesday is the most stressful day of the week.  So one in five work through lunch, and get an unhealthy snack early in the afternoon.

And everything catches up to you at about 3:30 on Wednesday afternoon.  Sorry ladies.
