Hyperhidrosis is the condition characterized by abnormally increased sweating/perspiration, in excess of that required for regulation of body temperature. It is associated with a significant quality of life burden from a psychological, emotional, and social perspective. As such, it has been referred to as the 'silent handicap'.

Aluminium chloride is used in regular antiperspirants. However, hyperhydrosis sufferers need solutions or gels with a much higher concentration to effectively treat the symptoms of the condition. These antiperspirant solutions or hyperhydrosis gels are especially effective for treatment of axillary or underarm regions. Normally it takes around three to five days to see the results. The main secondary effect is irritation of the skin. For severe cases of plantar and palmar hyperhydrosis, there is some success using conservative measures such as higher strength aluminium chloride antiperspirants. Treatment algorithms for hyperhidrosis recommend topical antiperspirants as the first line of therapy for hyperhidrosis.
