Do you tan easily? Do you get sunburn or freckles? The amount of melanin in your skin determines how it reacts to exposure to the sun and helps you determine your skin tone.
If you can easily and rarely get sunburned, you have more melanin and you probably have a warm or neutral complexion.
If you get sunburned and don’t tan, you have less melanin and a cooler complexion.
Some women with very dark skin may not easily get sunburned while having a cool complexion. Try several tests to verify it.
