Pure Aluminium Salts

Pure aluminium salts (>99% purity) are highly effective in reducing sweat, by temporarily forming a plug in the sweat glands.

Salicylic Acid

A recent study* showed that combining salicylic acid with aluminium salts boosts antiperspirant effectiveness. It clears the pores.

Peptide Complex®

A special peptide that helps reduce muscle activity in specific areas, such as the tiny muscles around sweat glands.

Natural Extract Blend®

Containing Witch Hazel, Aloe-extract, Glycerin and Pro Vitamin B. It works as a natural astringent, helping to reduce sweat flow.

    We use AluBlend™ in our formulas – a unique blend of Aluminum Salts, Salicylic Acid and Natural Extracts.
