Skin, your body’s largest organ, is complex. Its intricacy can make caring for it difficult and confusing, especially when you consider the environmental factors—sun, dirt, chemicals, humidity and more—you encounter daily.

“The fact is: Dermatology is really frustrating,” says Diana Hermann, an acupuncturist and herbalist, and owner of Zi Zai Dermatology in Fort Collins, Colorado. “It doesn’t matter whether you’re using Western medicine or natural medicine, skin varies greatly from one human to the next, so it’s challenging to know what to do.”
