The Role of pH in Skincare – Balance for Healthy Skin | Dr. Dermaluci Lab

🌿 What Is Skin pH?

Skin pH refers to how acidic or alkaline the skin’s surface is. Healthy skin usually maintains a slightly acidic pH between 4.5 and 5.5. This acid mantle protects against harmful bacteria, pollution, and moisture loss. When pH balance is disrupted—due to harsh cleansers, over-exfoliation, or environmental stressors—skin becomes prone to irritation, dryness, and breakouts.

🧬 How pH Affects the Skin Barrier and Microbiota

The skin barrier (stratum corneum) and the skin microbiota coexist in harmony when the pH remains stable. A balanced pH allows beneficial bacteria to thrive while preventing pathogens from multiplying. When pH becomes too alkaline, it weakens the lipid matrix of the barrier and disrupts the microbiota, leading to sensitivity and inflammation.

💧 pH and Active Ingredients: The Key to Absorption

Many actives—such as Vitamin C, AHAs, and Retinol—work optimally at specific pH ranges. Vitamin C (ascorbic acid) needs an acidic environment (around pH 3), while peptides and niacinamide perform better closer to neutral pH (around 5–6). Understanding pH compatibility helps you layer products effectively without reducing their efficacy.

✨ Maintaining Balance with Dr. Dermaluci Lab

Dr. Dermaluci Lab formulations are designed to support the skin’s natural pH balance. Our multi-molecular hyaluronic acid complex hydrates without disrupting the acid mantle, while the niacinamide strengthen the barrier and promote a balanced microbiome.

❓FAQ

Q: What is the ideal pH for skin?

A: Between 4.5 and 5.5 — slightly acidic to maintain the protective barrier.

Q: Can over-exfoliating affect pH?

A: Yes. Overuse of acids or scrubs can disrupt skin’s acid mantle and lead to irritation.

Q: How can I restore my skin’s pH?

A: Use gentle cleansers, avoid over-cleansing, and apply barrier-repairing products with prebiotics or ceramides.
