While taking professional courses to learn how to do an eyelash lift is a commendable step, it's generally not recommended to perform the procedure on yourself. Eyelash lifts involve using chemical solutions and specialized tools in close proximity to the eyes, which can pose risks if not executed with precision.

Here are a few reasons why it's safer to have someone else perform the eyelash lift:

1. Precision and Visibility: Achieving the desired lift requires precision, and it's challenging to maintain that precision when working on your own lashes. A professional can better see and access the lashes from the right angles.
2. Safety Concerns: Handling chemical solutions and tools near the eyes requires a steady hand and a thorough understanding of the process to avoid accidents or irritation. A professional is trained to manage these aspects safely.
3. Comfort and Relaxation: Having someone else perform the eyelash lift allows you to relax and enjoy the experience. Doing it yourself might be uncomfortable and potentially stressful, affecting the overall results.
4. Optimal Results: Professionals have the expertise to tailor the lift to your specific eye shape and desired look, ensuring optimal and satisfying results.

If you've completed a professional eyelash lift course, it's valuable knowledge that you can use to offer eyelash lift services to others. However, for your own safety and the best outcome, it's recommended to have a trained and experienced professional perform the procedure on you.
