Summary
Skin cooling significantly reduces pain from periocular botulinum toxin A injections. This simple method offers a 45% average pain reduction for patients undergoing cosmetic or therapeutic treatments.
Area of Science:
- Dermatology
- Ophthalmology
- Aesthetic Medicine
Background:
- Botulinum toxin A injections are common for cosmetic and therapeutic purposes.
- Periocular injections can cause significant discomfort and pain.
- Minimizing injection-related pain is crucial for patient comfort and compliance.
Purpose of the Study:
- To evaluate the efficacy of topical skin cooling in mitigating pain during periocular botulinum toxin A injections.
- To compare pain perception between cooled and non-cooled injection sites.
Main Methods:
- A prospective study involving 14 patients receiving bilateral periocular botulinum toxin A injections.
- One side of the face was treated with a skin cooling agent, while the contralateral side served as the control.
- Patients reported pain using a relative pain score system.
Main Results:
- The average pain score for the non-cooled side was 6.5.
- The average pain score for the cooled side was 3.6, representing a 45% reduction.
- Pain scores on the cooled side ranged from 0.5 to 7, compared to 3 to 10 on the non-cooled side.
Conclusions:
- Topical skin cooling is an effective method for reducing pain associated with periocular botulinum toxin A injections.
- This non-invasive technique enhances patient comfort during aesthetic and therapeutic treatments.
- Skin cooling offers a practical and beneficial adjunct for practitioners administering botulinum toxin A injections.
