How Does Drysol Work?

Drysol is an antiperspirant comprised of aluminum chloride hexahydrate. It is used to treat hyperhidrosis, a condition in which people sweat excessively. Hyperhidrosis is the secretion of sweat in amounts greater than is necessary to cool the body. It typically affects palms, soles of the feet or underarms. Drysol can be applied to each of these three areas to aid in preventing hyperhidrosis.

Drysol is more effective than typical over-the-counter antiperspirants because it contains aluminum chloride and alcohol which, when coupled together, are more effective in preventing sweating. Drysol is also effective due to the formulation of aluminum chloride hexahydrate in anhydrous ethyl alcohol, as this also helps prevent skin irritation. Most over-the-counter antiperspirants feature between 15 percent and 25 percent aluminum, whereas Drysol features closer to 40 percent.

Drysol works in that the aluminum is absorbed into the top layer of armpit skin. As the aluminum ions absorb into the cells, water is absorbed with them. This causes the cells to swell. Once swollen, the cells squeeze sweat glands shut, thereby eliminating the escape of perspiration. Once the cells retain all the water they can, water starts passing back out of the cells, and the cells eventually return to their original size. The sweating process then re-begins, at which time it is vital to apply more Drysol.

Apply Drysol to the area of excessive sweating, typically once before bedtime for the first few days, and then once or twice weekly as necessary. To achieve maximum performance, please make sure the skin area is completely dry before applying Drysol. Apply a thin layer of Drysol, and then cover the area with plastic wrap held in place by a tight-fitting shirt, sock or glove. It depends on the area being treated. Once you wake up, wash the treated skin area, making sure to avoid contact with your eyes. Also, Drysol should not be applied to irritable or recently shaved skin.

Drysol can stain clothing and can also cause a burning sensation when first applied. If you experience any ill effects for a sustained period of time, visit your doctor as soon as possible. Also, alert your doctor if you experience skin rash or swelling/irritation of the treated area.
