What is the optimal range of our skin's pH level?
Knowing the importance of the pH level and its role is essential for addressing our skin's needs.
The pH of your skin is naturally acidic and can vary depending on the body area. External factors such as the environment and your skincare regimen can impact the pH balance of your skin.
The term "pH (Potential hydrogen)" refers to the acidity level of substances. Understanding and controlling your skin's pH is essential for maintaining skin health.
The pH scale ranges from 1 to 14, where 7 is considered “neutral.” Numbers below 7 indicate acidity, while those above 7 are classified as alkaline or non-acidic. It may come as a surprise that a healthy skin pH tends to be more acidic. Increased acidity helps the skin fight off harmful microbes and damaging free radicals that could accelerate the aging process. However, balancing the skin’s pH can be somewhat tricky.
According to dermatologists, the ideal pH range is between 4.7 and 5.75, indicating that our skin is slightly more acidic than neutral. This slight acidity aids in preserving the balance of the skin's natural oils.
There are certain elements that may influence the pH of the skin:
sebum
skin moisture
sweat
genetics
age
detergents/soaps/gels
cosmetics/lotions
skin conditions
These factors may result in an imbalance in skin pH. An elevated skin pH level can exacerbate skin issues such as acne, eczema, rashes, dryness, and more.
How to check the pH of your skin
Below are three ways you can check the pH level of your skin.
At-home test strips
You can potentially determine your skin pH by using at-home pH kits. These kits typically consist of paper strips that you apply to your skin for measurement. For more accurate results, it is advisable to purchase pH kits specifically designed for skin testing. While saliva and urine tests can assess your body's general pH levels, they are not effective in indicating the pH of your skin's surface.
It is important to note that home kits may not provide the same level of accuracy as professional skin care testing.
Through a dermatologist
In their office, a dermatologist may provide pH testing as well as assistance with cosmetic and other skin-related services that pique your interest.
Observe and estimate
By carefully observing your skin, you can get an approximate indication of its pH level.
If your skin looks healthy with no dry patches, it may be considered balanced. Irritation, acne, redness, and dry patches could indicate a higher skin pH, tending towards a more alkaline state.
How to balance skin pH
Gentle cleansers
One of the easiest methods to preserve healthy skin is by using a mild cleanser that helps maintain balanced pH levels. By opting for a cleanser with a suitable pH, you can prevent the build-up of bacteria, oil, and dirt on your skin, which can result in breakouts and redness. Therefore, selecting a gentle cleanser that doesn't disturb your skin's natural pH balance is crucial. Try some of these empties that I have used.
2. Toner
Utilizing the appropriate toner is essential for balancing the pH levels of your skin and returning it to its natural state. This aids in preserving a healthy acid mantle, crucial for preventing harmful bacteria from entering the pores and supplying the skin with essential hydration. An effective toner will help encourage balance to the skin. Try one of these toners. All of them are non-comedogenic and have super ingredients.
3. Moisturize
Hydrating the skin is a highly effective method to achieve a harmonious skin pH level. By retaining natural oils, moisturizers create a protective barrier that prevents the skin from becoming excessively dry or oily. Adequate skin hydration plays a key role in controlling excessive sebum production, which may disturb the skin's natural pH balance. Moreover, moisturizing is key to alleviate inflammation and irritation, both of which can disrupt the pH balance of your skin. These moisturizers are not sticky and melt in your skin. You will feel hydrated.
4. Exfoliate
Exfoliation plays a dual role in skincare by clearing pores and eliminating accumulated dead skin cells, dirt, and debris that can disrupt your skin's pH balance. Additionally, exfoliation readies your skin for following treatments like moisturizing or mask application. Opting for mild yet potent products like BHAs and AHAs can rejuvenate your skin, leaving it revitalized and adequately hydrated. These exfoliants are my favorite. I love the powder washes in the shower and they really help to soften skin without hard abrasive ingredients. And the serum is a leave on so the next day your skin feels less congested.
The pH ranges for skincare products.
Here are the pH ranges of the majority of skin care products available on the market:
Cleansers pH 4.5–7
Toners pH 5–7
Sunscreens pH 5–7.5
Moisturizers pH 5–7
Serums pH 4–6
Vitamin C (ascorbic acid) products pH 2.6–3.2 (3.5)
Retinol products pH 4–6.6
Skin pH is just one element of overall skin well-being. Maintaining your skin with a suitable cleanser, toner, moisturizer and exfoliant is crucial for achieving the optimal oil balance necessary for healthy skin. Applying sunscreen daily is essential to shield your skin from UV light and other harmful particles. Specific skin issues like acne or dermatitis can be discussed with a dermatologist to address any underlying problems and ensure skin health.
