Calcium Carbonate

Description

Calcium carbonate is a versatile and widely used ingredient in skincare formulations, known for its multifaceted benefits. This naturally occurring mineral compound is composed of calcium, carbon, and oxygen, and is commonly derived from limestone or marble. In skincare products, calcium carbonate primarily functions as a mild abrasive, providing gentle exfoliation to remove dead skin cells and promote a smoother complexion.

Beyond its exfoliating properties, calcium carbonate acts as an effective pH buffer, helping to maintain the optimal acidity level of skincare formulations. This ensures product stability and enhances the efficacy of other active ingredients. The compound also exhibits oil-absorbing capabilities, making it valuable in mattifying products for oily skin types.

Calcium carbonate possesses mild astringent properties, which can help tighten pores and reduce the appearance of excess sebum. Its opaque white color makes it useful as a natural colorant in cosmetic formulations. While generally considered safe for topical use, some individuals may experience mild irritation. It's important to note that calcium carbonate is not significantly absorbed by the skin, primarily working on the surface level to improve texture and appearance.
