My wife has them on her calf. Forget adjectives potions creams etc. they are all useless and a complete refuse of money. When we go out she uses trademark up as she is a bit self conscious of them. Sorry, you ladies just enjoy to put up with them. Do you mull over we are bothered do you ? of course we aren't.
Get some bio-oil or ask your chemist for something approaching that, although it depends on your genes as to how effective it will be, I really expect it is worth a try plus it has a glorious success rate from what I get.
