The category of race has been used to group different peoples together or separately based upon Skin Tone.
What is Skin Tone?
The “tone” of your skin is the genetically endowed amount of melanin in your epidermis (the outermost layer of skin).
Melanin—a complex polymer produced by cells called melanocytes—refers to a group of naturally-occurring dark brown or black pigments present in human skin.
When the skin is exposed to damaging ultraviolet light from the sun, melanocytes kick into overdrive as a natural defense mechanism, producing an abundant amount of melanin spread across the epidermis is absorb the sun’s harmful rays. For that reason, determining your skin tone will vary depending on how much time you spend in unprotected sun exposure, but the skin tone you were born with is based on your genetic makeup.
There are three different categories you can use to determine your skin tone:
- Light: Light or fair skin tones tend to historically derive from northern European countries which faced frequent snow or cloud coverage, and therefore did not need much melanin protection. Paler people are usually very sensitive to the sun and burn much easier than those with darker skin. If you find that this is your skin tone, be extra diligent with your UV protection and consider daily sunscreen usage.
- Medium: Medium complexions are typical of Southern Europe and Northern Asian descent. Sometimes referred to “olive”, this skin tone is a neutral, well-balanced beige appearance and will make finding the right foundation shade much easier. If you determine this is your skin tone, you probably tan well in the sun (note: that doesn’t mean you’re immune to sun-related aging.
- Dark: Dark complexions typically originate from parts of the world that have the most exposure to ultraviolet radiation, such as the Middle East, India, and Africa. As with those who have medium skin, you are not exempt from sun damage if you have this skin tone, and are in fact more prone to hyperpigmentation, so hold onto that sunscreen.
