The Ordinary Lactic Acid 10% + HA – 30ML

**Lactic Acid 10% + HA**

**Description:**

Lactic Acid 10% + HA is a water-based serum designed for effective surface exfoliation and enhanced skin texture. Formulated with 10% lactic acid, an alpha hydroxy acid (AHA), this serum helps to gently exfoliate dead skin cells, promoting a smoother, more radiant complexion. It is complemented with hyaluronic acid (HA) for added hydration, making it ideal for dry skin types.

**Key Benefits:**
– **Exfoliation**: Removes dead skin cells from the surface for a refreshed, smoother texture.
– **Hydration**: Hyaluronic acid boosts moisture levels, helping to maintain skin hydration and prevent dryness.
– **Reduced Irritation**: Purified Tasmanian pepperberry extract helps to minimize irritation and sensitivity often associated with acid exfoliants.

**pH and pKa Considerations:**
– **pH**: Approximately 3.8, which is optimal for lactic acid efficacy.
– **pKa**: 3.8. The pKa value indicates the availability of lactic acid for exfoliation. A pKa close to the pH of the product ensures effective exfoliation with minimal irritation.

**How to Use:**
1. Apply a few drops to clean, dry skin in the evening.
2. Avoid using with other strong acids or retinoids.
3. Follow with a moisturizer to lock in hydration.
4. Use sunscreen during the day, as exfoliation can increase sensitivity to UV rays.

**Note:** Suitable for dry skin types and those new to acid exfoliants. Always patch test before use and gradually introduce into your skincare routine.
