first of all, a story from a friend's experience. when he went to Italy, a friend took him to shop. he didn't want to buy anything coz they were so expensive. but the friend insisted that he should buy some clothes for himself and said: good clothes can't make a man, but it helps.
so we should say here, good cosmetics can't make a woman, but they do help!
don't put your main concern on price when it comes to two things, cosmetics and underwears. just choose what you want and like. don't hope the cosmetics can reduce your wrinkles or prevent the aging,just remember they help.
