How Sodium Lactate Enhances Skin Hydration, Soothes, and Improves Skin Texture

Sodium lactate, a salt derivative of lactic acid, is a highly effective humectant that draws moisture into the skin, ensuring long-lasting hydration. It is commonly used in skincare products for its ability to replenish skin moisture, improve texture, and enhance the overall appearance of the skin. Sodium lactate is particularly beneficial for dry, dehydrated skin and sensitive skin types, as it offers soothing and skin-softening properties.

Composition of Sodium Lactate

Sodium lactate is composed of:

• Lactic Acid Derivative – comes from the natural fermentation of carbohydrates and is more stable in skincare products than lactic acid

• Humectant – draws moisture from the environment into the skin, helping to keep it hydrated

• Naturally Derived – typically derived from plant sugars, making it a more eco-friendly option

Key Features of Sodium Lactate

1. Hydrating Properties
   Sodium lactate works to draw moisture from the environment into the skin, providing deep and lasting hydration.

2. Soothing and Calming
   It helps to soothe irritated or sensitive skin, reducing redness and inflammation.

3. Improves Skin Texture
   Helps smooth rough patches and promotes an overall soft, even skin texture.

4. Enhances Skin Barrier Function
   It aids in strengthening the skin's moisture barrier, preventing water loss and promoting healthier skin.

5. Mild and Gentle
   Sodium lactate is non-irritating and suitable for all skin types, including sensitive skin.

Applications of Sodium Lactate in Cosmetics

Sodium lactate is used in various skincare and cosmetic products, primarily for its hydrating and soothing properties:

   By enhancing the skin’s barrier function, sodium lactate helps to lock in moisture and protect the skin from external environmental stressors.

5. Non-Irritating
   It is generally well-tolerated by most skin types, including those prone to irritation or dryness.

Limitations and Considerations

• Overuse Can Lead to Excessive Hydration
  In rare cases, using too many products with humectants like sodium lactate can overwhelm the skin’s ability to retain moisture, leading to potential dehydration if not balanced with occlusive agents.

• Sensitivity to Concentration
  While generally safe, higher concentrations of sodium lactate may cause minor irritation for some individuals, so it’s important to start with lower concentrations and gradually build up.
