Aluminium Chloride

Aluminium chloride can cause stinging, itching, redness or irritation, particularly when applied to damp or recently shaved skin. Moisture can react with aluminium chloride to produce hydrochloric acid, which may irritate the skin. To reduce the risk, apply it to completely dry, unbroken skin and follow the medication instructions. If irritation becomes severe, persistent or painful, stop using the product and seek advice from a pharmacist or healthcare professional.

It is usually applied at night to completely dry skin, allowing it to work while sweating is reduced. Initially, it may be used nightly for several days, depending on the product instructions and severity of sweating. Once symptoms are controlled, applications can often be reduced to once or twice a week, or as needed.

Always follow the directions for your specific aluminium chloride treatment and avoid applying it more frequently than recommended.

Aluminium chloride can begin reducing excessive sweating after the first few applications, although results vary between individuals. Many people notice an improvement within a few days when using the treatment correctly. For best results, apply it to completely dry skin at the recommended frequency.

If your sweating does not improve despite following the instructions, speak to a pharmacist or healthcare professional about alternative treatments for hyperhidrosis.

Aluminium chloride can generally be used for ongoing management of excessive sweating when applied as directed. However, prolonged or excessive use may increase the risk of skin irritation, dryness and itching. Once sweating is controlled, you may be able to reduce how often you apply it. Avoid broken or inflamed skin, and seek advice from a pharmacist or healthcare professional if irritation persists or you need to use the treatment more frequently than recommended.

The main difference between aluminium chloride treatments and regular antiperspirants is their strength and intended use. Standard antiperspirants are designed for everyday sweat control, while aluminium chloride treatments often contain a higher concentration of the active ingredient and are used to manage excessive sweating, or hyperhidrosis.

Stronger formulations may be more effective when ordinary products are insufficient, but they can also cause more skin irritation. The right option depends on your symptoms and skin sensitivity.
