Collomack® Topical Solution 17.4% is a German topical medicine containing salicylic acid 174 mg/g (17.4%) for the removal of corns and calluses (thickened, hardened skin). It is intended for adults, adolescents, and children 1 year and older.

Salicylic acid has a keratolytic action, meaning it gradually softens and loosens excessive layers of hardened skin. This makes the thickened tissue easier to remove after treatment.

Important: The current German Collomack Topical 17.4% formulation is indicated for corns and calluses, not warts. This distinguishes it from some older/international Collomack formulations and other salicylic-acid wart products.

Active Ingredient

Salicylic acid penetrates the hardened skin and progressively causes the thickened layers to soften and detach.

Other Ingredients

• Acetone
• Copovidone
• Ethylcellulose
• Medium-Chain Triglycerides
• Purified Water

How to Use

Unless otherwise directed, apply Collomack Topical 1–2 times daily directly to the corn or callus.

Use the applicator/spatula to apply the solution to the affected area and allow it to dry.

Protect the surrounding healthy skin with petrolatum (Vaseline) or zinc paste if necessary.

Treatment for approximately 3–4 days is generally sufficient to soften a corn or callus so that the loosened hardened skin can be removed after a warm foot bath. Treatment may be repeated if necessary.
