Combination skin is widespread and is perhaps the most difficult to treat because it requires both a normalizing and a moisturizing-nourishing action at the same time.
The characteristics of this skin type are a combination of dry and oily skin, where the latter is, in fact, only found in the T-zone (forehead, nose and chin), where there is a larger number of sebaceous glands.
Combination skin therefore needs to be balanced and purified and at the same time protected and nourished.
