The Ordinary Lactic Acid 10% + HA is a water-based serum containing 10% lactic acid, an alpha hydroxy acid (AHA), and 2% hyaluronic acid (HA). It's designed for exfoliation, targeting the skin's surface to improve texture and clarity. The addition of HA helps hydrate and calm the skin, potentially reducing irritation from the exfoliation. It also includes Tasmanian pepperberry extract, known for its anti-irritant properties. 

Here's a more detailed breakdown:

• Lactic Acid: AHA that gently exfoliates by loosening and removing dead skin cells. 
• Hyaluronic Acid (HA): A humectant that attracts and retains moisture, helping to hydrate and plump the skin. 
• Tasmanian Pepperberry Extract: Helps to soothe and reduce irritation associated with exfoliation. 
• pH: Approximately 3.8, a slightly acidic pH that is optimal for lactic acid's exfoliating action. 
• Suitable for: Dry skin, uneven texture, dullness, and fine lines. 
• How to use: Apply once daily, ideally in the evening, and consider diluting it with other treatments to start until your skin builds tolerance. Avoid using on sensitive, peeling, or compromised skin. 
• Benefits: Can improve skin texture, reduce the appearance of fine lines and dark spots, and brighten the complexion.
