I think mine started to show at the age of 4 when I went to school. Omar is exposed to lots of sunlight since he was a baby, he has 2 only one on his tummy & on on his back. DH shoulders & back are covered & I have few on my face & shoulders. They'r genetic. My mum & 2 of my brothers are covered with freckles. My 3rd brother doesn't have any although my dad have freckles on his body only. And skin colour has nothing to do with freckles, my eldest brother & dad have olive dark skin. I'm very pale & Dh, mum & youngest brother's skin is also white but not as pale as mine
