Understanding pH and Its Role in Skincare

What is pH?

pH, or Potential Hydrogen, is a logarithmic scale used to measure the acidity or basicity of liquid solutions. The scale ranges from 0 to 14, with 0 being the most acidic, 7 representing neutrality, and 14 being the most basic.

As skincare professionals, we recognize that the ideal pH value for healthy skin falls between 4.5 and 5.5. However, several factors can influence this balance, including:

  • Sebum and sweat
  • Genetics and age
  • Cosmetics and skincare products
  • Certain skin conditions

The acid mantle—a thin protective layer on the skin—defends against environmental pollutants, bacteria, and moisture loss. When this protective barrier is compromised, the skin becomes vulnerable to irritation, dryness, and breakouts.

The Importance of Balancing pH

Maintaining a balanced pH is essential for overall skin health. Product compatibility and consistency play a crucial role in restoring and preserving this balance, helping to reduce skin irritation and improve barrier function.

Facial treatments can be an excellent way to rebuild and maintain skin health. At Skin Script, we provide product knowledge videos in our Learning Center to help professionals select the best products for various skin types.

There is no “one-size-fits-all” approach in skincare. As professionals, we must analyze each client’s symptoms and customize their skincare regimen accordingly. Over time, as the skin barrier improves, their homecare routine may need adjustments to support ongoing skin health.

pH & Skincare Products

Understanding the pH levels of skincare products is essential, as different pH values interact uniquely with the skin. In our Training & Reference Manual, we list the pH value of each enzyme to help professionals make informed choices.

How pH Levels Impact Skincare Products:

  • High pH (Alkaline Products): These can strip the acid mantle, leading to compromised skin that appears dry, itchy, sensitive, acne-prone, inflamed, or uneven in tone and texture. Fine lines and wrinkles may also become more pronounced.
  • Acidic Cleansers (pH Below 6): These may improve acne but can also over-exfoliate the skin if used too frequently, weakening the acid mantle and increasing skin sensitivity.
  • Balanced Formulas: Properly formulated products help maintain skin health without disrupting its natural barrier.

How to Maintain pH Balance:

  • Buffering Enzymes: To reduce tingling and increase pH, mix equal parts of any enzyme with our Goji Berry Yogurt Mask. This allows clients to enjoy the enzyme benefits while protecting their skin barrier.
  • Daily SPF Use: Protects skin from UV damage that can disrupt pH balance.
  • Healthy Lifestyle Choices: Proper hydration, a balanced diet, and mindful skincare routines contribute to maintaining an optimal pH.

Final Thoughts

pH balance is a crucial factor in skin health, influencing everything from hydration levels to sensitivity and acne. By understanding the role of pH in skincare products and treatments, professionals can help clients achieve stronger, healthier skin.
