Before I start I'm not immune to this. I'm 59 and I do still dye my hair and use anti ageing moisturiser. But I do have fine lines and creases at the corner of my eyes when I smile. I don't care though. I've never had any fillers or Botox. I reckon I could pass for 55 in a good light.
But it does seem to be that the ultimate compliment to a woman, apart from "have you lost weight?" is "you're how old? Gosh I would never have guessed". It doesn't seem to be an issue for men - in fact for a 40 year old man to look in his late 20s would be a bit embarrassing.
It seems though that women are indoctrinated into this "you must not age" from a young age. Just recently a poster's 16 year old daughter had asked for a subscription treatment that is usually only available on prescription for acne. It's really sad. So why do we still buy into this idea that our main worth as women is our youth and beauty?
