The rates of loss of firmness and elasticity of the skin varies from person to person, depending on their genetic makeup, general health, excessive sun exposure, the system of skin care, or lack of, and other factors. As the skin becomes less elastic, it also becomes drier the underlying fatty tissue begins to disappear as a result of the skin begins to sag. Our skin is less flexible, and wrinkles begin to form. At this stage, our skin is more easily injured, heals more slowly and tends to dry faster. The role of pH in acne As noted above, the pH of the skin is important and maintaining a pH slightly acid of about 5.5 is critical. PH of the skin is a major contributor to acne and other skin problems.
Propionibacterium acnes is a bacterium that normally lives on the skin and is a normal bacteria found in all people regardless of the presence or absence of acne. However, in people prone to acne, the number of P. acnes is much higher. It was found that the growth of this bacteria is highly dependent on pH of skin and growth is at its lowest in normal skin pH of 5.5. A slight shift towards the alkaline pH would provide a better environment in which to prosper. Importance of pH of the skin: Do’s and Don’ts One of the main culprits that radically alter the pH of the skin, is soap. Ordinary soaps, available in the market are highly alkaline (pH range 9-11) and raise the pH of the skin to be much more alkaline.
