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.
  • Traditional indication for chronic eczema and athlete's footAs the main component of acid springs, aluminum has long been used in Japanese balneotherapy for skin diseases. This traditional application is known for addressing chronic conditions like eczema and fungal issues like athlete's foot.
