It's the skin of course.
For those of you who have had anatomy.. you probably beat me to answering the question.
So one of the biggest changes I have been noticing has to do with my skin. Yeah I know I am approaching old crow age; but that doesn't mean I don't want to have nice skin. In fact, I tend to obsess about it (alot). I have every cream, serum and exfoliating technique that money can buy. I visit spas and the dermatologist for micro dermabrasions, skin peels, lasers etc. I take Biotin, and Omega X's. I spend oodles of dollars to combat the wrinkles. I have had shots, and nips, and a few tucks. I am the only person that uses SPF 90000 in the summer. I shade my face from the sun. I DON'T WANT WRINKLES.
Ok, so I think I am doing myself a favor by loosing a few pounds and ZAP.. creepy, wrinkly skin appears... NOOOOOOOOOOOOOOOO.
But yes, its there... being fat makes you look younger (at least in the face).So now I am dwelling onthe lines in my neck.
They say the hands and necks are the first to show your age. I am constantly lathering my self up good, each night I use my clarsonic and serums. Please tell me this stuff snaps back into shape. At the rate I am going I will turn into a Sharpei (you know the wrinkle puppy).
Oh well.. I guess plastic surgery will be inevitable.. I better start saving..
