Normal to combination skin

Normal skin is the most common. But even here we cannot set precise boundaries, so to speak, what is black and what is white, because human skin is very variable. So we encounter normal skin with a tendency to greater greasiness or dryness or to dysseborrheic manifestations, but also to dull skin with dysseborrheic manifestations (comedones), the pre-menstrual period (influence of hormones) plays a role here. During the treatment, we then eliminate or, on the contrary, add everything that, according to logical reasoning, is inappropriate or suitable at the given moment. Therefore, we are talking about the current state and not about skin types, because, for example, in a quarter of a year, event. even before, the skin condition may be different.
