Study summary

Botulinum toxin type A (commonly referred to as 'Botox') injections are a treatment that dermatologists regularly use to smoothen wrinkles such as 'Crow's feet', to rejuvenate the skin surrounding the eye (the 'periorbital region'). However, botulinum toxin type A can be associated with injection-site bruising that may take up to 2 weeks to heal.

Hirudoid, an ointment that is applied to the skin, has been shown to reduce the severity of swelling and bruising after facial cosmetic procedures. The objective of this study is to study the effectiveness of Hirudoid in reducing the severity of bruising following the use of botulinum toxin type A for periorbital rejuvenation of Crow's feet in adult patients.

The knowledge gained from this study can help to develop an effective medicated skincare regimen that helps to minimize the complications of botulinum toxin type A and speed up recovery time, which may be of benefit to patients who receive botulinum toxin type A injections for treatment of Crow's feet.

Read the detailed description

This is an investigator-initiated, real-world, multicenter, prospective, interventional study to assess the effectiveness of topical Hirudoid for both preventing, and reducing the severity (intensity and extent) of ecchymosis after periorbital rejuvenation with botulinum toxin type A. This will be an intra-individual comparison study, where the study drug will be applied to one side of the face, and the other half of the face will receive no treatment.

Planned follow up is up to 10 days with assessments scheduled at Days 1, 2, 5, 7, and 10 post-botulinum toxin type A injection. The total number of mandatory in-person visits would be 2, including a visit on the day of botulinum toxin type A injection (Day 0), and a follow-up visit on Day 7 post-procedure.

Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Study arms

  • Experimental
    Hirudoid

    All enrolled and eligible participants who are planning to receive botulinum toxin type A for lateral canthal lines will receive the study drug (Hirudoid).

    Drug: Hirudoid (heparinoids) ointment, 3mg/g

Interventions

  • DrugHirudoid (heparinoids) ointment, 3mg/g

    This study is to observe the effectiveness of Hirudoid on ecchymosis after treatment of Crow's feet with botulinum toxin type A. Hirudoid is a topical treatment that is indicated for the soothing relief of superficial bruising and haematoma. It may potentially reduce the severity (intensity and extent) of bruising, and/or increase the speed of resolution of bruising after periorbital botulinum toxin A injection. Hirudoid will be applied to one side of the face (randomized allocation of left or right) for all eligible participants, 30 minutes before the botulinum toxin type A injection procedure, and three times a day, starting 24 hours after the procedure, until post-procedure Day 10. A 2 centimetre ribbon of Hirudoid will be applied to the affected area (i.e. the lateral canthal lines injection site), and massaged into skin until absorbed.

What researchers measure

Primary outcomes

  1. Area (extent) of ecchymosis around the eye

    Area (extent) of ecchymosis around the eye with Hirudoid versus 'no treatment' on day 7 post-procedure with botulinum toxin type A for the treatment of lateral canthal lines. Patients will be instructed to take daily photographs of both sides of face, which will be shared with clinician and analysed with online software to measure area of bruising using a freehand selection tool to trace the border. Results are to be inputted into the electronic case record form in cm2. A separate independent assessment will take place for each image, by a second physician who is blinded to initial results.

    Time frame: Day 7 post-procedure with botulinum toxin type A

Secondary outcomes

  1. Area (extent) of ecchymosis around the eye

    Area (extent) of ecchymosis around the eye with Hirudoid versus 'no treatment' on days 1, 2, 5 and 10 post-procedure with botulinum toxin type A, using the methodology described for primary endpoint. Patients will be instructed to take daily photographs of both sides of face, which will be shared with clinician and analysed with online software to measure area of bruising using a freehand selection tool to trace the border. Results are to be inputted into the electronic case record form in cm2. A separate independent assessment will take place for each image, by a second physician who is blinded to initial results.

    Time frame: Days 1, 2, 5 and 10 post-procedure with botulinum toxin type A

  2. Intensity of ecchymosis around the eye

    Intensity of ecchymosis around the eye with Hirudoid versus 'no treatment' on days 1, 2, 5, 7 and 10 post-procedure with botulinum toxin type A for the treatment of lateral canthal lines. Patients will be instructed to take daily photographs of both sides of face, which will be shared with clinician and analysed against a 5-item scoring system (adapted from Rostami et al. 2020) for assessing the intensity of ecchymosis around the eye, where higher scores indicate greater post-procedure bruising. Rating: 0 (no colour change); 1 (yellowish colour change); 2 (light purple); 3 (dark purple); 4 (very dark purple). A separate independent assessment will take place for each image, by a second physician who is blinded to initial results.

    Time frame: Days 1, 2, 5, 7 and 10 post-procedure with botulinum toxin type A

  3. Duration (days until resolution) of ecchymosis

    Duration (days until resolution) of ecchymosis with study treatment versus 'no treatment' assessed based on visual assessment by the physician using the using the scoring system adapted from Rostami et al. 2020. Patients will be instructed to take daily photographs of both sides of face, which will be shared with clinician and analysed against a 5-item scoring system for assessing the intensity of ecchymosis around the eye, where gradual reduction of ratings indicate resolution. Rating: 0 (no colour change); 1 (yellowish colour change); 2 (light purple); 3 (dark purple); 4 (very dark purple). A separate independent assessment will take place for each image, by a second physician who is blinded to initial results.

    Time frame: Day 1 to Day 10 post-procedure with botulinum toxin type A

  4. Global patient satisfaction

    Global patient satisfaction relating to the impact and outcomes of Hirudoid treatment, evaluated by a 5-point Likert-scale questionnaire (1=very dissatisfied to 5=very satisfied) on day 7 post-procedure.

    Time frame: Day 7 post-procedure with botulinum toxin type A

  5. Number of participants with treatment-related adverse events as assessed by CTCAE v4.0

    Incidence and type of local adverse events will be summarized descriptively using count and percentages for both the arms.

    Time frame: Day 1 to Day 10 post-procedure with botulinum toxin type A

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 5, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
