2 ADDITIONAL STEPS FOR VERRUCAS for optimal preparation and after-treatment
PRIOR TO THE TREATMENT First, soak the foot in warm water for 5 minutes and then rub the callous carefully with a file (widely available for purchase) to expose the verruca. Dry it thoroughly so there is no water/moisture between the wart and the Wartner TCA gel. Do not apply the TCA gel when the skin is bleeding or broken. A file not included. STEP 1-4 Same as for removal of warts as above. Once treatment is complete, carefully clean the Wartner Pen with a tissue before storage. AFTER TREATMENT![]() |
After applying the TCA gel and let it dry for 10-15 minutes, you could experience some discomfort when pressure or friction occurs on the treated area. You may find it helpful to protect the sensitive area with a comfort plaster which is widely available for purchase. Comfort pads not included. |

Does TCA acid work faster than Salicylic Acid?

- The effects (keratinisation and peeling off the skin) are visible soon after the first round of treatment (4 days with 2 daily applications).
- SPCs of traditional OTC wart & verruca treatments based on salicylic acid tend to indicate daily usage and a treatment time of up to 12 weeks.
- According to a pooled-analysis of 16 different clinical trials assessing the efficacy of salicylic acid treatments, the mean cure rate with salicylic acid treatment for removal of warts is 52%. In the same pooled analysis, it is recommended for trials to follow-up at a period of 12 weeks.
- Another controlled trial assessing the efficacy on warts of a treatment with salicylic acid (40%) applied during 13 weeks showed a cure rate of 24%, wheareas Wartner Wart Pen offers a complete removal up to 65% of treated warts & verrucas only after 4 weeks.
How does TCA gel work compared to salicylic acid?
TCA gel is an effective acid for a convenient and fast removal of warts & verrucas
Salicylic acid | TCA gel | |
Treatment period | 8 to 12 weeks | Effective from the first week |
Suitable for children | Certain references | Yes |
Acid concentration | ++ | +++ |
Applicator | Brushes/tubes | Pen |
Form | Mostly liquid | Gel |
Systemic effects | Can have systemic effect, or can cause blood coagulation | No effect on blood coagulation |
- TCA is scientifically proven to have a long lasting peeling effect on the wart, which allows a continuous action on the wart. It destroys the HPV virus.
- The pH rate of TCA= 1.9 whereas salicylic acid has a pH rate of 2.4, which means that TCA is a stronger acid than salicylic acid.
- Wartner Verruca & Wart Removal Pen is in gel format while salicylic acid compositions are generally in liquid form. The gel combined with the innovative applicator allows a more precise application on the affected spot without too much invasion of the healthy skin around it.
