I'm mid forties and have never worn makeup except for a bit of lipstick on the odd occasion like weddings etc. My face has become really blotchy with age and I'm thinking that i should grow up and maybe wearing a little might help but I literally have no clue what to buy or how to apply it. Those really made up sales ladies in boots & debenhams terrify me and I suspect their stuff is v. expensive and they'll sell me stuff I don't need. Help!!
