What is the skin pH?
The pH scale ranges from 0 to 14. Seven is the neutral pH level and below 7 is considered acidic pH and above 7 is considered alkaline pH.
The pH value of skin is 5.7. However, it differs across the body. If the pH value of skin changes then it becomes susceptible to damage. Your skin starts feeling dull, and becomes acne-prone. There are various ways to care for your dull skin and acne prone skin.
Why is it important to maintain skin pH level?
When skin has an optimal pH level, it possesses improved barrier function, less scaling and better moisture retention. A slightly acidic skin pH assists the healthy bacterial flora to remain attached to the epidermis.
When the acid mantle (protective film) of the skin becomes too alkaline, it becomes vulnerable to sensitivity and dryness.
Moisturizers can solve the problem of dry skin. Keep this in your skin care puch. Along with moisturizer, you can also follow some tips for dry skin.

If you use products with high pH, then it affects the permeability of skin and your skin becomes susceptible to skin problems, such as:
- Atopic dermatitis: Studies find higher pH values in areas of intense dry and itchy face. There are certain factors responsible for this. Free amino acids and urocanic acid that are thought to have a role in forming the acidic milieu of the stratum corneum (SC), which is the outer layer of the skin, are decreased in atopic skin.
- Tinea pedis: According to a study the foot skin pH is high in tinea pedis patients. Tinea pedis is a fungal infection, which generally starts between the toes. Its symptoms include a scaly rash, which can be itching and burning. You can try good moisturizing foot cream to control the condition.
- Acne: P.acnes grows well at pH range between 6 and 6.5. The growth is considerably decreased at pH values of less than 6. Therefore, it is very important to use skin care products with the right pH and right ingredients. One of such ingredients is benzoyl peroxide.

Some of the medications such as chemotherapy, antibiotics and diuretics and medical procedures including dialysis and radiotherapy can also affect natural defense of skin, change its optimal pH and damage its barrier function.
The pH of male and female skin varies somewhat. This happens because the rate of sebum production is higher in male skin.
