Question

Why do some people tan and others just get burnt and peel?

Answer 1

it just matters what kind of skin you have and if you want a tan use tanning liaison

Answer 2

There can be numerous reasons why some people tan better than others.  A lot depends on your skin type and your ethnic background.  African-American people can burn just as easily as caucasian people too.  The amount of melanin (the amount of cells that absorb light) that your body contains can make a difference.  Also,  sometimes being on certain medications can make you photosensitive or become more easily sunburned.  Just remember, even if you tan easily you should still wear a sunscreen to avoid long-term damage to your skin.♥

Answer 3

People have different skin tones

Answer 4

different skin types

Answer 5

people has different skin types like i tan and one of my friends burns (like crazy) While protecting your body, skin must protect itself from the sun's ultraviolet radiation, which can cause premature aging and cancers. Sunscreens can help. Sunburn occurs when strong UV rays harm cells in the skin's outermost layer, the epidermis. Blood vessels in deeper layers dilate, turning the skin red: a sunburn. Regular exposure causes the epidermis to produce more melanin pigment in an attempt to absorb UV rays. If enough melanin accumulates, the skin darkens: a tan. Dark-skinned people have more melanin than light-skinned people and so don't burn as readily.

Active chemicals in sunscreen also filter UV rays, slowing injury and thus the sunburn and tanning reactions. Sunscreens are labeled with an SPF, or sun protection factor--a relative rating standardized by the FDA. Say that skin begins to burn after 10 minutes of exposure. When it is protected by an SPF 15 sunscreen, a comparable burn will take 15 times as long. An SPF 30 sunscreen will slow the burn for 30 times as long. But don't get cocky. Labs rate sunscreens on human subjects at a density of two milligrams per square centimeter, according to J. Frank Nash, a principal scientist at Procter & Gamble. Yet a typical beachgoer lathers up at perhaps half that concentration, halving protection. And Nash says no compound can fully stop UV penetration; there's no such thing as sunblock.

You can discount claims about antioxidant vitamins E and C.  Oxidation accounts for only a few percent of the UV damage, notes dermatologist Barbara A. Gilchrest of the Boston University School of Medicine, and "there's no good evidence" that vitamins in topical products can even enter the skin in active form.  More worry comes from the fact that sunscreens primarily filter the shorter, or UVB, ultraviolet wavelengths, yet recent studies show that the longer (UVA) rays may contribute more to skin aging than previously thought.

So what's the best sunscreen? A thick shirt. And because cell damage is cumulative, experts recommend daily use of sunscreen, or of moisturizers with sunscreen, on areas such as the hands and face. A one-hour exposure every day for five days could be as threatening as one long day at the beach.

Sunscreen VS. Tanning Oil

The skin's surface, with its many micropeaks and valleys, scatters a small number of the sun's ultraviolet rays. Most of the rays penetrate the epidermis. Melanin absorbs many of these photons, but some of the remainder injure DNA in the living cells. This damage signals capillaries in the dermis to dilate, increasing blood content and producing redness, or sunburn. Sunscreen acts as a filter that absorbs additional UV rays, dissipating their energy. Tanning oil smooths the surface, so fewer rays scatter and more penetrate, speeding sunburn or tanning.

Beneath the Surface

Two main layers make up the skin. The dermis contains blood vessels and nerves. The epidermis contains melanin, an inert protein that gives skin its color. Melanocytes insert melanin granules inside cells as newly formed cells push older ones to the surface. As the cells migrate, they produce keratin, another inert protein, and then die, leaving the keratin to form the tough stratum corneum we see every day. The same keratin also constitutes our hair and nails, as well as the feathers, scales, hooves and claws that adorn eagles, trout, horses and alligators.

DID YOU KNOW?

  PABA-FREE

For decades sunscreen makers used para-aminobenzoic acid (PABA) as an active ingredient. But it stains clothes and causes an allergic reaction in 5 percent of the population, and controversial evidence suggests it might be carcinogenic. Today many brands shout out "PABA-free."  

  YOUR EPIDERMIS IS SHOWING

Melanin, the epidermis pigment that absorbs ultraviolet rays, also absorbs visible light. The more eumelanin (brown pigment) you have, the darker your skin color, from white to black. Redheads produce relatively more phaeomelanin (red and yellow), a poorer UV absorber, so they are more likely to sunburn and less likely to tan. Albinos have no melanin and are at great risk in the sun.  

  TRUCKER'S ELBOW

Glass absorbs UV rays very effectively, so you can grip your car's steering wheel for hours in baking heat and not sunburn your hands or arms. But roll down the window and rest your elbow on the ledge, and you might arrive with a telltale burn truckers know well.  

  TAN IN A BOTTLE

"Sunless" tanning sprays and lotions contain dihydroxyacetone (DHA), which binds to amino acids in the outermost (dead) layer of skin to produce a tan--some more realistic than others. They provide no UV protection, however, so sunscreen is still needed outdoors.

Answer 6

well becuz they dont want skin cancer or they are to lazy to stand or lay under the sun

Answer 7

Different skin tones. Like for me, i get sunburned and then my sunburn turns into a tan. So other people are different because my dad and my brother sunburn and peel and my mom gets a regular tan.
