Understand what skin tone means. Your skin tone, or undertone, does not refer to the shade of your skin (light, medium, dark)--that is your complexion, or the surface color of your skin. Your skin tone is determined by the amount of melanin, or pigment, in your skin and does not change from sun exposure or skin conditions like rosacea or acne.[1] So while a person's skin may become pale in the winter and a rich brown in the summer, their skin tone will remain the same.
Your skin tone will be one of the following: cool, warm, or neutral.[2]
Keep in mind your skin tone does not necessarily match what you see on the surface. So you may have pink or ruddy skin, but your skin tone may actually be yellow.[3]
Before attempting any of the following steps, make sure your skin is clean and free of any makeup, lotion, or toner. If you just washed your face, wait about 15 minutes before proceeding, as your skin may appear pink from scrubbing and make it difficult to see your true undertone.[4]
Always use natural lighting when examining your skin. Different lightbulbs can affect your skin differently--they may give it a yellow or green cast, and interfere with the appearance of your skin tone.[5]
