Salicylic Acid | Lactic Acid | Trichloroacetic Acid Solution

All three acids are keratolytics, meaning they break down the tough outer layer of skin (keratin). Salicylic and lactic acids loosen and dissolve dead skin cells so the wart tissue can be removed. Trichloroacetic acid adds a stronger chemical peel that helps destroy virus-infected cells. You may notice mild softening or whitening of the wart in the first few days. Visible shrinking often starts after 1–2 weeks, but complete removal may take 6–12 weeks of steady use. Once the wart is gone, normal skin slowly grows back.

Do not use if you are allergic to salicylic acid, lactic acid, trichloroacetic acid, or any component of this product (may cause severe rash or swelling). Do not use on the face, genitals, mucous membranes, or broken, infected, or irritated skin (can cause burns). Do not use on moles, birthmarks, or any growth that has hair, color changes, or bleeding—see a provider for those. Do not use if you have diabetes, poor blood flow, or nerve damage in the hands or feet unless your provider specifically approves (higher risk of severe skin injury). Not for children under 2 years of age. Avoid if you are pregnant or breastfeeding unless your provider decides the benefit outweighs the risk, because large areas of skin exposure could increase systemic absorption.

Using other topical products that peel or dry the skin (such as retinoids, benzoyl peroxide, topical alcohol, or strong soaps) at the same spot may increase redness, burning, or peeling—space applications or use only one product at a time. Oral medicines that raise skin sensitivity to irritation or sunlight (such as isotretinoin, some antibiotics like doxycycline) may heighten local side effects. Avoid covering the treated area with tight, air-proof dressings unless told by your provider; this can increase acid absorption and irritation. Tell your provider about all prescription drugs, over-the-counter medicines, and herbal supplements you use, even if you apply them to a different body area.

Very common (more than 1 in 10 people): mild stinging or burning for a few minutes after application, slight skin whitening. Common (1–10 in 100 people): redness, dryness, flaking, mild pain, peeling. Uncommon (1–10 in 1,000 people): blistering, dark or light spots after healing, small surface scar. Rare but serious (less than 1 in 1,000 people): deep chemical burn, severe swelling, signs of infection (pus, spreading redness), or a widespread allergic reaction (hives, trouble breathing). Most minor effects improve within a few days after stopping the medicine. Seek medical help right away if you notice severe pain, spreading redness, or signs of allergic reaction.

Store tightly closed at room temperature (68–77 °F, 20–25 °C) in an upright position. Keep away from heat, sparks, and open flame; the solution is flammable. Protect from direct sunlight and do not freeze. Keep out of reach of children and pets. Do not transfer to other containers. Discard unused or expired product through a pharmacy take-back program or mix with cat litter or coffee grounds in a sealed plastic bag before throwing in household trash.
