Combination skin is simply having oily skin in some areas of your face and dry skin in other areas.  Typically, there's a mix of oily and dry areas on different parts of your face, with the T-Zone (forehead, nose) being slightly to very oily.  U-Zone (cheeks, chin), is usually slightly dry to very dry.  Your skin responds sensitively to imbalances to skin condition and seasonal changes.

Take care of the combination skin with different methods depending on the face area.  First, use the Vallatto Oil Mist and Calming Balance Gel to calm and moisturize, then follow with the sequential application of the Dermatology Booster->Serum->Booster.

T-Zone (oily Forehead + Nose), continue with the Calming Balance Gel to soothe and moisturize the skin, then Cocktail Aqua Sun Gel and finish with the Cocktail Aqua BB Cream.

U-Zone (Dry Cheeks + Chin), continue with the Active Cream, then Cocktail Aqua Sun Gel and Cocktail Aqua BB Cream, and finally spray the Vallatoto Oil Mist to strengthen the skin barrier.
