the skin protects us from mechanical damage, chemical damage, bacterial damage, ultraviolet radiation, thermal, and desiccation.
Physical,if you use your 5 senses for it its physical
it is chemical because it can not be reversed
Skin tanning is an example of a chemical reaction.
"sunburn" results from physical damage caused to your skin by overexposure to Ultraviolet emissions, usually from the sun but it can also come from a UV lamp. UV light affects damage to the DNA of your skin cells. In defense those cells will produce melanin, a chemical response to try to repair this damage, which also darkens the color of the skin ( a "sun tan").
No, sunburn is a physical change rather than a chemical change. It involves damage to the skin from overexposure to ultraviolet radiation from the sun, rather than a change in the chemical composition of the skin.
Bleaching skin is a chemical change because it involves a reaction with the skin's melanin pigment that alters its chemical structure to appear lighter in color.

This phenomenon is of physical nature.
Chemical.
Bruises are the consequence of a physical action.

its a physical because its a change in the state of matter just like boiling water

Applying makeup is a physical change, not a chemical change. It involves rearranging or altering the appearance of the substances (e.g., pigments, powders) on the skin without changing their chemical composition.
