The skin's pH plays a crucial role in strengthening its defence system. The topmost layer of the skin is called the acid mantle. This acid mantle acts as a barrier and protects the skin from external aggressors, inhibits the growth of bacteria and maintains the optimal acid level for the skin to thrive. This implies that the skin is naturally equipped to fight infection and environmental stress on its own. However, its ability to do so is influenced by its pH level. The acid mantle is made up of sebum (oil) that mixes with sweat, amino acids etc. to create the skin s pH, which should ideally range between 4.5 to 5.5 on a scale from 1 (most acidic) to 14 (most alkaline). When skin is too acidic, it results in breakouts whereas when it is too alkaline, it results in dryness. In both these conditions, the skin s defence system (barrier function) gets compromised leading to cell damage. Most cleansers tend to disrupt this balance which is why it becomes imperative to find a cleanser that can not only cleanse the skin but also maintain its pH level.
