Calcium Gluconate is a mineral salt made from calcium and gluconic acid. In skincare, it is used as a skin-conditioning ingredient.

Key benefits:

Improves formulation performance 

Calcium Gluconate is a compound derived from calcium and gluconic acid that is used in both nutrition and cosmetic applications. In skincare, it functions primarily as a skin-conditioning ingredient thanks to its moisturising and skin-supporting properties. It is thought to promote a healthy-looking complexion as well as acting as a stabilising agent in many formulations (3).

People with dry or dehydrated skin 

Those looking to support a weakened skin barrier

People with mature skin concerned with loss of suppleness

Calcium is important for healthy skin and a well-functioning skin barrier. Calcium Gluconate may help support skin-conditioning benefits, although its effects will depend on the overall formula and how it is used (4). Calcium Gluconate is generally also used as it plays a supporting role in the formulations of many skincare products to help the product perform better in its desired function.

Calcium Gluconate is commonly found in face creams, barrier-support moisturisers, restructuring serums and anti-ageing treatments. It is often combined with ingredients such as ceramides, niacinamide and hyaluronic acid.

The takeaway

Calcium Gluconate is a skin-conditioning ingredient that helps support hydration and is a useful addition to formulas designed for dry or sensitive or mature skin.
