Tag: Acidic ph

The average pH of healthy skin is between 4.7 and 5.75, which is slightly acidic. When you apply a highly concentrated vitamin C serum, particularly one with L-ascorbic acid, its low pH can clash with your skin's natural pH, triggering that familiar tingling sensation. This initial tingle is often normal, but understanding its root causes is key to differentiating a product that is 'working' from one that is irritating your skin.

According to food science, the process of carbonation involves dissolving carbon dioxide ($CO_2$) gas in a liquid, which forms carbonic acid ($H_2CO_3$), thereby lowering the pH. This change in acidity is the primary factor that determines how and if carbonation affects proteins, a crucial topic for anyone interested in nutritional science or food production.

Overproduction of acid or excessive loss of bicarbonate can cause blood pH to drop below the optimal range of 7.35–7.45, a condition known as acidosis. When your pH is too acidic, it forces the body to pull alkaline minerals from bones and vital organs to neutralize the acid, impacting overall health.
