In Ayurveda, we “type”  ourselves into one of three categories based upon a multitude of physical, mental, behavioral and other tendencies that we were born with called doshas.  We all have some of each dosha in us, but generally one dominates.  This is helpful to know so you can be the guide of your own health maintenance, and also skin care.  The doshas are named: Vata, Pitta, and Kapha.  Vatas are usually have dry, rough skin.  Pittas have red, inflammed, irritable skin.  Kaphas have naturally oily, luminious, but acne prone skin.  Tridoshic individuals are very rare, and products labeled "tridoshic" compliment any skin type.
