That's an interesting article and underlines that there are many factors involved - lifestyle, nutrition, age, genetics all have their part to play. If you are treating your body well and drinking plenty of water, not smoking or drinking alcohol of caffein to excess you are giving yourself a better chance - creams, oils and lotions help to keep the skin supple (it notices on a daily basis) so it's not a bad idea if you want to give it a go. At the end of the day we are all different and you may or may not end up with saggy skin. Good luck - I'm keeping my fingers crossed too x
