PH of skin

It’s official now pH is the new black oil. From dermatologists’ offices to the shelf of beautiful women, “pH balance” is the phrase on every beauty's well-moisturized lips. The market has already started to flood products with its pH-focused toners, cleanser, pH strips, moisturizers, and even advanced wearable pH sensors. When comes to certain beauty products and treatment products that claim to restore the pH balance of the skin. In the market, there is a rush for claiming to be the best available option, and certainly, some snake oil is being sold.

While certain dermatologists, aestheticians, and emerging wellness gurus may have their different philosophies, all agree to the point that pH levels are very important to overall skin health. So we thought it would be great to answer some basic questions about pH balance like, What is pH balance? And why should you care about it in your search for great glowy skin?

What is the pH of skin?

The pH is actually a numeric scale that indicates how acidic or alkaline a solution is. On a pH scale of 1 to 14, 7 is neutral, below 7 is acidic content while above 7 is alkaline. But what does that have to do with skin anyway?

The normal pH of your skin is at 4.7, PH is not the only trending word nowadays but the wellness gurus are talking about how the pH can affect the “acid mantle,” a thin barrier on the skin surface that maintains its acidity. It is believed that by any means you disturb this skin mantle by overuse of harsh products, there will definitely be consequences.

Newborns have relatively quite high pH levels all over their skin. As the baby gets older, their pH levels decline rapidly. Their average pH is about 7 compared to the average pH of adults which is 5.7.

Skin pH also varies depending on the area of your body. Like armpits, buttocks, or genital areas which are less exposed tend to maintain their own natural acidity. Unlike your chest, face, and hands, which tend to be more alkaline as they are more exposed areas.

Other factors which affect skin pH are:

  • Air pollution
  • Acne
  • Antibacterial products
  • Cosmetic products
  • Changing seasons, with a different humidity level
  • Detergents
  • Antibacterial soaps 
  • Skin moisture
  • Tap water
  • Sweat
  • Overexposure to the sun
  • Frequent skin washing

Which pH level is good for skin?

The ideal skin’s pH is 5.5, which is slightly acidic in nature. When it’s balanced at 5.5, then it is the optimum level for the skin. If it gets imbalanced then your pH levels will suffer considerably resulting in wrinkles, sensitivity, acne, or inflammation. Our skin and body require a balance between acidity and alkalinity for a good level of the acid mantle which serves as the barrier to help our skin in keeping hydration in and toxicity of skin out. Anything that goes over seven is considered to be alkaline. Skin to this scale tends to be wrinkly and drier while skin that is on a large acidic scale can appear irritated, red, and itchy.

How to test skin pH at home?

Few ways to test skin pH at home:

Stripes For Home Test 

Many thanks to at-home pH testing kits, it is now possible to determine your skin pH in the comfort of your home. These are in the form of paper strips that are applied to your skin and then measured.

Urine tests and even saliva can measure the overall pH levels of your body but these will do little to nothing to tell you the pH of the surface of your skin.

Observe And Estimate

Another way to determine the skin pH level can be possible through careful skin observation.  Balanced skin is skin that has a soft texture in itself in the absence of any dry spots present. Any kind of irritation, redness,  acne, and presence of any dry spots may all sign towards the high skin pH that is leaning towards a more alkaline scale.

Take Away

A daily sunscreen routine is also a must-have for protecting your skin from the damage of the UV light and other particles present in the atmosphere like dust to say.

Any other specific skincare issue, such as dermatitis, or acne is brought to be addressed by a reputed dermatologist. They can help you in resolving underlying skin issues and help you in making your skin healthy again and forever.
