Skin PH
Skin pH – the reaction of the skin, which determines the alkalinity and its acidity. The natural pH of the skin should be shifted slightly towards the acidic side, i.e. around 5-6 on a 14-degree scale. The right reaction allows you to maintain a healthier appearance of the skin and avoid some problems. A higher pH above 7 may result in dryness. In the case of a lower pH around 4.5, there may be an overproduction of sebum, a tendency to breakouts and enlarged pores. A product that will help restore the right pH is toner.
