What is Aluminum ion?

Aluminum ion (Al³⁺) is the key component of acidic springs. Its strong astringent action tightens the skin and has traditionally been used for oily skin and skin troubles.

Main Effects

  • Strong astringent action tightening the skinAluminum ions bind with proteins on the skin's surface, creating an astringent effect. This process tightens the epidermis, which may help make pores appear less noticeable and give the skin a firmer feel.
  • Calming oily skin and acneThese springs may help control the excess sebum production associated with oily skin. Additionally, the water's natural acidity creates an environment that can inhibit the growth of bacteria that contribute to acne.
  • Traditionally used for chronic eczema and athlete's foot
