MD - I got my eyelashes tinted and brows waxed on a whim last week for the first time ever and the comments have been amazing. Seriously ridiculous, people suggested all sorts from losing weight (who would have known the brows were so heavy, lol) to having botox (which cracked me up as I am petrified of anything like that). But it has made me feel great! So I am a convert now.....
I also try and moisturise in the morning, SPF on the face and drink heaps of water and walk for a bit each day.
Let me know if you find out your friends secret, maybe it is a secret love, lol!
