Cath I don't post pics of mine online neither do I edit them to make myself look prettier. I think your colleague has her own way, it is difficult for some women to accept their looks after some particular age. My daughter had fallen prey of this harsh critisism, too, her Facebook photos look way different from her in real life. That's sad to see but it is her decision to make.
Oopsadaisy3 you can try Photodiva, my daughter uses it to remove wrinkles from her face. Honestly, I think it is a little bit strange, she looks lovely in her thirties but she won't listen to me.
