I've aged 6 years in a month. It's all dry skin, fine lines and wrinkles and dark under eye circles over here I think I looked better overall after I stopped breast feeding my son when he was 10 months. My hormones evened out and my body was mine again. My sex drive increased and I looked less haggard.
I've always had them but I invest in a good serum, moisturizer, primer, and bb cream and I look refreshed every day even when I'm not. I really love dr. Jart skin products. The only non dr jart I use is my serum which is marcelle 8in1 and my revlon undereye concealer/brightener. Even with all the zits that I have now, I'm keeping them under pretty ok control. I use the burts bees blemish roll on for those (no salicylic acid) before I apply anything else.
Re: Under eye circles
I'm thinking they will get WAY worse shortly after birth due to lack of sleep, but then should go away in about 18 years. That's my prediction!
