try using ooh la lift by benefit if your lines around your eyes. try using a really good concealer like YSL touche elcait to minimise the appearance of fine lines.
to prevent fine lines: get plenty of sleep, try not to get stressed, stay hydrated by drinking plenty of water, dont smoke, limit how much alcohol you drink, oh and also eat loads of fruit and veg. these things make sound like common sense but they REALLY do help
