I just get a bunch of freckles and maybe some very slight tanning in between the freckles.

On beach vacations, my brother in law and his kids would immediately get the most amazing tans. Especially the niece.

If I was not very careful, I would blister and peel.

Had auburn hair (part English, French and German).

Brother in law would lay out in the sun for hours and hours.
Now he gets the skin cancers burned and cut off his face a few times a year.
