Lactose

Description

Lactose, a disaccharide sugar found naturally in milk and dairy products, has gained prominence in skincare formulations due to its multifaceted benefits. This ingredient, composed of glucose and galactose, possesses hygroscopic properties that make it an effective humectant, attracting and retaining moisture in the skin. Lactose's molecular structure allows it to penetrate the stratum corneum, enhancing skin hydration and improving overall texture.

In skincare products, lactose serves as a gentle exfoliant, promoting cell turnover without causing irritation. Its alpha-hydroxy acid (AHA) properties contribute to mild chemical exfoliation, helping to remove dead skin cells and unclog pores. Additionally, lactose exhibits antioxidant capabilities, potentially protecting the skin from free radical damage and supporting collagen production.

Formulators often incorporate lactose into moisturizers, serums, and masks due to its compatibility with various skin types, including sensitive skin. Its natural origin and low potential for irritation make it a versatile ingredient in both leave-on and rinse-off products. Lactose also functions as a stabilizer in emulsions, enhancing the texture and shelf-life of skincare formulations while providing skin-nourishing benefits.
