>due to constant exposure that part of my body is more resistant compared to the pasty areas.
This is of course true, and it took me half a lifetime to realize I could get deep tans and stay out in the sun without any sunscreen, all it took was to "DCA" my way into sun exposure at the beginning of the summer. Concerted efforts to get 5, 10, 15, 20, 25, 30 minutes of unprotected sun exposure that slowly increase but not to the point of burning.
I also realized that sunscreen does not need to be so liberally or frequently applied- particularly mineral sunscreen, the thinnest possible film is all that is needed for hours of protection if you aren't swimming or sweating excessively.
It goes against mainstream advice that no sun exposure is good exposure, and that getting a tan is not healthy. However I never "tan" my hands and they don't look any darker, but I've never burned them, even though they're the place that will get the most sunscreen rubbed off. Ditto for feet.
