In the context of skin treatments, what is the main effect of applying negative ions?

Applying negative ions in skin treatments primarily increases skin hydration and softens the skin. Negative ions are believed to interact positively with the skin’s surface, helping to enhance moisture retention. This moisture retention is crucial for maintaining skin elasticity and suppleness, leading to a softer texture.

Additionally, negative ions may create an environment that encourages a healthy skin barrier, which can further improve the skin's ability to retain moisture. This effect is particularly beneficial for individuals with dry or dehydrated skin, as it helps combat common issues associated with dryness.

While other effects are often discussed in skin treatments, such as skin tightening or reducing infection risk, the primary known benefit linked to the application of negative ions is their ability to improve hydration and softness of the skin. Therefore, in the context of skin treatments, focusing on hydration and softness aligns with the positive effects attributed to negative ions.
