Understanding Your Skin's pH
For some, the term "pH of the skin" might evoke memories of physics and chemistry classes, and for the well-versed, its definition and importance remain fresh in their minds. For everyone else, here's a refresher combined with skincare tips.
The Basics of Skin pH
The pH, or potential hydrogen, is a measure of acidity of a solution or element, ranging from 0 to 14. A neutral pH is 7. Below this, the pH is acidic; above, it is alkaline or basic.
Our skin, comprised of approximately 70% water, has a specific pH level that must be maintained. Typically, human skin's pH ranges from 4.7 to 5.5. This acidity protects against external aggressors like extreme weather conditions (hot and cold), pollution, and UV exposure. This value varies across different parts of our body and face, as well as with age.
Beyond its chemical definition, pH is essential for the skin to produce a balanced combination of lipids and water. Water and sebum blend on the skin only when its natural "slightly acidic" pH is upheld.
Proper regulation of sebum and hydration helps nourish and preserve our hydrolipidic film, the most crucial layer of our epidermis.
Products to Maintain Your Skin's Natural pH
To maintain our skin’s natural pH balance, it's crucial to select natural and organic cosmetic products with a pH close to that of our skin.
For instance, our Phyt'acid cleanser from the PHYTO 5 Swiss range deeply cleanses while maintaining the skin's natural pH and protecting the hydrolipidic layer.
Follow with an emulsion of oil and water matched to the skin's pH, like our Crème acide from the same PHYTO 5 Swiss range. The presence of fats and water in a cream with a slightly acidic pH allows for the immediate restoration of the hydrolipidic film. As this film is also made of sebum (lipids) and water, using an acidic cream naturally aids its restoration.
Daily Skincare Tips
Remember to shield your skin from UV rays and cold, common disruptors of its natural pH. Be mindful of hormonal changes and avoid harsh products (both skincare and makeup) that are too aggressive for your skin, as they can cause irritations.
In understanding and supporting your skin's delicate pH balance, you'll enhance your skincare routine and better protect your skin's health and appearance.
