Heavy Water - Ingredient Explanation

Heavy Water

Function: Solvent

1. Definition Heavy Water:

Heavy water, also known as deuterium oxide, is a form of water that contains a higher concentration of the isotope deuterium rather than the more common hydrogen isotope. Deuterium is a stable, non-radioactive form of hydrogen that has an extra neutron in its nucleus.

2. Use:

Heavy water is used in cosmetics for its hydrating properties. It is believed to help improve skin hydration and moisture retention, making it a popular ingredient in moisturizers, serums, and other skincare products.

3. Usage Heavy Water:

Heavy water is typically used in small concentrations in cosmetics, as it can be expensive to produce. It is often included in formulas alongside other hydrating ingredients like hyaluronic acid or glycerin to boost the overall moisturizing effects of the product. When using cosmetics containing heavy water, it is important to follow the instructions provided by the manufacturer and to perform a patch test before applying it to your face to ensure that you do not have any adverse reactions.
