No. All humans have a skin thickness of approximately the same depth. Darker skin has an advantage of reflecting ultra violet light better and thus reducing the harm of sunlight. The color of skin is a result of pigmentation and not a basis for qualification. People vary from stark white through dark brown and there is little difference other than cultural between them.

The thickness of a person's skin is determined by the amount of collagen it has in it. Collagen is a fibrous protein found in skin, bone, cartilage, tendons and connective tissue.
If a person has little collagen in his skin it could easily break and bleed, especially in a fall or a fight. This has been a problem with some boxers and I saw a report on the Discovery Channel about a White boxer who was trying to remedy it with collagen treatments.
The skin of black people apparently does produce more collagen than that of white people. Please see web link below.

However, as with everything, I'm sure they are talking only about averages and that a wide range of collagen content can still be found in both peoples.
Black people have a skin pigment called melanin which exists in greater quantities than in white people. This pigment offers greater protection from the UV rays of the sun. For this reason, blacks are less susceptible than most other peoples in the world to sunburn and skin cancer. Since UV rays contribute to wrinkling too, blacks are better protected against that as they age too.
Light skin seems to have evolved largely as protection against rickets and frostbite but it offers weak protection against the sun.
Nevertheless, black people can still be sun-sensitive (or sun-allergic) too in certain instances just as much as everyone else.
When I was a kid, one of our neighbors was a black lady who suffered from a severe case of Xeroderma Pigmentosum and had to stay indoors during the day. Xeroderma Pigmentosum is a genetic disorder which has nothing to do with melanin or a person's skin color. It can effect anyone of any race.
It's a sad disease. People who have it must stay indoors during the day with the blinds closed. Nighttime is their favorite time of day.

Are you black? My black friends DO sun burn, true you cant see it, but they do feel it the same. Not all "whites" do wrinkle fast.

You're stupid. sorry to say and mostly you're ignorant [sorry if that was too big of a word] no skin is thicker than the next at least not to my knowledge. Blacks don't burn the same as whites because of the pigments in their skin tones, that causes differences. DUH!
