Sodium Lactate

Sodium Lactate is the sodium salt of lactic acid, a natural component of the skin's Natural Moisturizing Factor (NMF). It is an excellent humectant, attracting and holding moisture in the skin, which helps to keep it hydrated and supple. It also functions as a pH regulator in cosmetic formulations, helping to maintain the product's stability and effectiveness.

Whether the ingredient helps increase the skin’s water content — humectants that attract water, ingredients that reduce water loss, or ones that make skin feel less dry.

Soothing i0.5 / 4

Whether it can calm the skin — linked to less redness, irritation, discomfort, or visible reactivity.

Texture i0.5 / 4

Whether it can improve smoothness and surface texture — roughness, flaking, clogged pores, or unevenness. Exfoliating acids, retinoids, and smoothing moisturizers may score here.

Frequently asked questions

How does Sodium Lactate differ from Lactic Acid?

While both are derived from lactic acid, Sodium Lactate is a salt and primarily functions as a humectant and pH buffer, providing hydration without the exfoliating properties of Lactic Acid. Lactic Acid, an AHA, is primarily used for exfoliation and can be more irritating at higher concentrations.

Is Sodium Lactate suitable for sensitive skin?

Yes, as a component of the skin's natural moisturizing factor, Sodium Lactate is generally well-tolerated and considered suitable for sensitive skin. It provides hydration without the potential irritation associated with exfoliating acids.
