Understanding pH Value: The Secret to Healthy, Radiant Skin

When it comes to skincare, we often hear buzzwords like hydration, anti-aging, or natural ingredients—but one crucial factor that's often overlooked is pH value. At CallistaÉVA, we believe true skin health begins with balance, and pH plays a powerful role in maintaining that balance.

What is pH Value?

The term pH stands for "potential of hydrogen" and measures how acidic or alkaline a substance is on a scale from 0 to 14:

• 0–6.9 = Acidic
• 7 = Neutral
• 7.1–14 = Alkaline (Basic)

In skincare, pH matters because your skin’s natural pH is slightly acidic, typically around 4.5 to 5.5. This natural acidity helps maintain your skin’s protective barrier—known as the acid mantle.

Why pH Balance Matters for Your Skin

Your skin’s acid mantle protects against:

• Bacteria & environmental pollutants
• Moisture loss
• Irritation & inflammation

When skincare products are too alkaline (high pH), they can strip your skin of natural oils, weaken the barrier, and lead to dryness, sensitivity, or breakouts. On the other hand, products that are too acidic can cause stinging, redness, or irritation.

The Ideal pH for Skincare Products

For optimal skin compatibility, the best products have a pH close to that of your skin—between 4.5 and 6. At CallistaÉVA, we formulate every product with this balance in mind to support your skin's health, resilience, and glow.

How to Maintain Your Skin’s pH Balance

Here are a few skin-smart tips:

• Use pH-balanced cleansers and toners – Avoid harsh soaps or foaming products with high alkalinity.
• Don’t over-exfoliate – This disrupts your barrier and throws off the pH.
• Hydrate and protect – Moisturizers with humectants and barrier-repair ingredients help restore pH after cleansing.
• Check for product compatibility – Using too many actives or layering products with clashing pH levels can confuse your skin.
