pH is known as potential of Hydrogen . The scale which is use to measure the pH is known as pH scale . pH scale helps to measure the acidity or alkaline character . The measuring scale ranges from 0-14 and pH can be checked with litmus paper. If the litmus paper turns to red, that indicates the acidic level. and if the litmus paper turns blue, that indicates the alkaline level
pH 7 is known as neutral which is neither acidic nor alkaline. The range 0-6 indicates Acidic range and 8-14 indicates Alkaline range. means, moving towards 0 from 7 increases the acidic level and moving towards 14 from 7 increases the alkaline level.
now the question arises what is the role of pH in makeup . To get clear details first let us know the pH of our skin . Study says, our skin is fairly acidic, which helps to keep away the harmful bacteria and fungi from our skin surface. The pH of skin is 5.5. If the acidic level of skin increases then dryness of skin increases. So here comes the role of knowing pH balance for skin in makeup. We know that tonner helps to maintain pH balance. When we cleanse the skin of face , the pores of the skin opens up. If we use any facewash and soap that imbalances the skin as those products are towards alkaline level because soap is a combination of weakly acidic and strong base.
That is why in order to retain the pH balance of the skin we use tonner . Tonner comes in the form of liquid. It balance the skin pH and shrinks the open pores which we get during cleansing step. It also provide hydration to skin because of its ingredients . Even in market we get different tonner. Even some are specific for dry skin and some for oily skin. so based upon ingredients, we should opt the tonner which gives more hydration for dry skin. Also should opt tonner which doesn't contain any oily substances for oily skin.
Another role of pH for our skin is linked with the home remedies that we prefer. Every ingredient has pH balance.
so the product for which pH balnce is lesser than our skin pH can be avoided for the dry skin orelse it will increase the acidic level of our skin and will turn that to extream dry.On the contrary, those products can be use for oily skin. example. - citrus acid ( lemon) . The pH banalce of lemon juice is 2.4 which is lesser than skin pH. using that directly on dry skin will increase the acidoc level and will make more dry to our skin . we can add any other alkaline product with lemon to increase the pH and can be used on dry skin. The pH balance of the product which is more alkaline also should be avoided for oily skin.
Attaching the picture of pH scale for better idea.
How to use tonner on our skin :-
Tonner comes in spray bottle which can be directly sprayed on face from a certain distance after cleansing the face. Tonner comes without spray can be applied with help of cotton . Taking adequate amount of tonner in cotton , dab or tap on your face gently. Let the tonner set on your skin for atleast 60-120 seconds. Then you can move towards the step for Moisturizer.
