Discoloration is Determined by Skin Tone

Discoloration, also known as hyperpigmentation, can arise from a variety of different aggressors. Lighter skin doesn’t contain very many melanocytes or melanin (which is responsible for giving skin and hair their color), making it more susceptible to hyperpigmentation. However, discoloration can affect all skin tones and types.
Light skin tones tend to have a pink undertone and can burn easily in the sun. Acne scars, sun spots, bruising and broken capillaries are more apt to show up on lighter skin because it is thinner and fair.
The most common skin tone among Caucasians and Asians, light- to medium-colored skin has beige or yellow undertones, and hyperpigmentation of all forms can be a common concern.
Darker skin types—think Latinas and those of Mediterranean descent—have medium or olive skin tones and are more prone to acne scarring, sun damage and prolonged hyperpigmentation.
Very dark skin types are most common in African Americans. Although it has more melanin, very dark skin can burn (even though it doesn’t show as much), is prone to sun damage, and is more susceptible to developing brown spots.
Whether your hyperpigmentation is brown, pink or red, the discolored portion of your skin is basically signaling that it’s been damaged. In terms of how deep damage can go within the skin, it’s mostly dependent on the color, size and age of your hyperpigmentation.

SPF: Does it Matter?

With summer approaching, let’s take a look at the value of a higher SPF vs. a lower SPF in your sunscreen.

Higher SPF’s aren’t always necessary. You need to look at a couple of things when shopping for a sunscreen. First, how light is your skin tone? Those with lighter skin will usually burn faster than those with darker or olive tone skin. If your skins turns red very quickly, you’ll want a higher SPF.

But what does the SPF rating really mean?

SPF stands for Sun Protection Factor. To figure out how long you are safe from the sun (at least the UVB rays), you need to do a little math. Take the number of the SPF and multiply it by 10. That is the time you’d be safe from the sun’s rays under perfect conditions. (For example, SPF 20 * 10 = 200 minutes).

Perfect conditions, however, mean you aren’t sweating or in the water – both of which often go hand in hand with sun exposure. This also doesn’t reflect that sunscreen can rub off on your clothes or towel.
Because you always want to protect your skin from the sun, the best bet is to apply sunscreen every 1-2 hours, no matter what the SPF is.
