so, i'm in TX, on a ranch & it's HOT most days - including todays 108 in the shade - LOL
sunscreen is my only moisturizer & a ball cap and big sun glasses are the norm. i have naturally dark skin (italian/jewish) - but, my mom threw SPF in my face at an early age.
in hot climate - protect yourself; i will naturally get tan just walking out the door - but i do like jergen's self tanner to blend things in.
at the end of the day - i think a healthy glow makes you look fit; thinner is in the eye of the beholder & the size of your thighs...
