Frequently Asked Questions

Will it stain my skin?
Yes — any skin touched by water containing Avoca will turn black temporarily. This fades naturally within a few days as the skin renews.

Can I use it on a child?
Always seek pharmacist or doctor advice before using on children. The pencil is fragile — handle with care.

Always read the label and use strictly as directed. If symptoms persist or worsen, consult your pharmacist or doctor. Our Pakuranga pharmacists are happy to help — call us on 09 577 2616.
