Understanding pH Balance in Skincare

The word “pH” may sound like chemistry class, but for your skin, it’s a matter of harmony. Every cleanser, toner, or moisturizer you use interacts with the skin’s natural acid mantle — a delicate layer that maintains balance. At Aurevia, we design formulas that respect this invisible ecosystem to preserve both protection and radiance.

What Is Skin pH?

pH stands for “potential of hydrogen,” measuring acidity or alkalinity on a scale of 0 to 14. Healthy skin typically has a pH of around 4.5 to 5.5 — slightly acidic. This acid mantle acts as a barrier against harmful bacteria, pollution, and moisture loss.

When pH Is Out of Balance

Using overly alkaline products (like harsh soaps or high-pH cleansers) can strip away natural oils and disrupt the acid mantle. This imbalance leads to dryness, sensitivity, and breakouts. Conversely, products that are too acidic can irritate or over-exfoliate. Balance is key.

The Science Behind the Acid Mantle

Your acid mantle is composed of sebum (oil), sweat, and natural acids from amino acids and lactic acid. Together, they maintain optimal pH and support beneficial bacteria that protect against pathogens. Disrupting this system can weaken the skin’s immunity and trigger inflammation.

Choosing pH-Balanced Skincare

• Opt for gentle cleansers labeled “pH-balanced” (around 5.5).
• Use mild exfoliants with AHAs/BHAs no more than twice a week.
• Restore balance with toners containing amino acids or hyaluronic acid.

Ingredients That Support pH Harmony

• Lactic Acid: Gently refines texture while maintaining hydration.
• Sodium PCA: A natural humectant that stabilizes acidity.
• Ceramides and Niacinamide: Reinforce the barrier after pH fluctuation.

Environmental Factors

Frequent washing, hard water, and pollution can raise skin pH. Even stress and poor diet influence acidity levels. Regular use of barrier-supportive products helps restore equilibrium.

The Aurevia Promise

We believe in skin that self-balances. Every Aurevia cleanser and essence is formulated within skin’s natural range, preserving the acid mantle’s integrity. Because when your pH is balanced, your glow is effortless.

Balance is beauty — and science is the way to it.
