That is it really. I'm 44 and kind people regularly express surprise at my advanced age so generally fairly wrinkle free etc for my age but my neck seems I have looked at my passport recently and now looks a bit haggard ( for lack of a better word). "Necklace" type marks but most distressing to me is that the skin immediately under my chin seems to have just gotten thin and sort of "pulled" looking. Thank goodness it is winter and so scarves will be worn BUT does anyone have any helpful advice. Does anyone do neck exercises and do thy work if you do them faithfully?
