What should I do if I’m not sure whether a lump is a wart or not?
Are there other types of warts?
Yes, apart from common warts, a range of wart types have been identified, varying in shape and site affected, as well as the type of human papillomavirus involved. These include:
Common warts (Verruca vulgaris): These are discrete, flesh-coloured papules, with a rough surface. They may be single or multiple and occasionally can be quite large. They are most common on the hands, but may occur anywhere. They are usually relatively easy to treat.
Plantar warts (Verruca, Verruca pedis): These are discrete and only just raised, having a roughened surface. They can occur on the palm but usually found on the sole, where they penetrate deeply because of the pressure of the body weight and are most difficult to treat. They may be quite painful and can interfere with walking. Minute haemorrhages may occur within them due to trombosed capillaries, which is visible by multiple black specks in the centre. They are usually found on pressure points on the soles of the feet.
Plane warts (Verruca plana): These are small, smooth flattened warts, flesh-coloured, which can occur in large numbers. They can occur everywhere, bust most particularly on the face, neck, hands, wrists and knees. They are quite frequently misdiagnosed, particularly on the face. They often occur in lines corresponding to a scratch or other such trauma.
Filiform or digitate wart: A thread or finger like wart, most common on the face, especially near the eyelids and lips.
Genital wart (venereal wart, Condyloma acuminatum, Verruca acuminata): They occur on the genital area.
Mosaic wart: A group of tightly clustered plantar-type warts, commonly on the hands or soles of the feet.
Periungual wart: A cauliflower-like cluster of warts that occurs around the nails.

- Scars and nerve damage: this will only occur from careless use caused by not following the instructions on the information leaflet. Never use Wartner Wart Pen Wart Pen on healthy tissue, as TCA is a highly corrosive agent that will damage normal skin.
- In case the wart is very small and the treatment is maintained too long or too frequent, TCA may cause peeling of the deeper layers of the skin.

Does TCA acid work faster than Salicylic Acid?
- When applied, the TCA peeling effect appears immediately. The peeling effect remains longer after application compared to other acid treatments
- 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.
