    Frequently Asked Questions

    Is bruising normal after filler injections?

    Yes, bruising is a common and expected side effect of filler injections. It occurs when the needle or cannula passes through small blood vessels. The likelihood depends on the treatment area, injection technique, and individual factors like medications and supplements.

    How long does bruising last after Botox?

    Botox bruising is typically minimal and lasts 2-5 days. The needle used for Botox is very fine, so significant bruising is uncommon. Small pinpoint bruises at injection sites usually resolve within a few days.

    What does the bruising color progression look like?

    Bruising follows a predictable color timeline: Day 1-2 red/pink, Day 2-4 purple/blue, Day 4-7 green/yellow-green, Day 7-14 yellow/light brown, then fully resolved. This progression indicates normal healing.

    How can I reduce bruising after injection?

    Apply a cold compress for 10 minutes on, 10 minutes off during the first 24 hours. Arnica supplements (started 3 days before treatment) and arnica gel can help. Avoid blood thinners, alcohol, and intense exercise for 24-48 hours.

    When should I call the clinic about bruising?

    Contact your clinic if bruising is accompanied by severe pain, expanding swelling, skin color changes to white or grey (which may indicate vascular compromise), vision changes after facial injections, or if bruising has not improved after 2 weeks.

    Does the injection technique affect bruising?

    Yes, significantly. Cannula techniques generally cause less bruising than needle techniques. Experienced injectors use careful technique and anatomical knowledge to minimize vessel trauma. Dr. Waleerat uses cannula techniques where appropriate to reduce bruising risk.
