If you have combination skin, you probably already know that typical skin solutions just don't do the trick. With different zones requiring treatments, your best bet is to use a technique called multi-masking. Using different masks for different areas allows you to tailor the effects to your unique needs. For example, a clay mask can be used on your oily T-zone, while a moisturizing cream mask can be applied to dry patches under your eyes or on the chin to produce even results.
