Does FaceID improve over time?

I switched to iPhone 11 recently and I find FaceID rather disappointing, it often analyzes my face several times before recognizing it and sometimes I have to type my code. I tried to reconfigure it and do it in different situations but it didn't change anything.

Does the technology improve when you use it, with a kind of learning machine? How do I get him to recognize my face better?

As the system is used, it learns about typical variations in a user's appearance, and will adjust its registered face data to match aging, facial hair growth, and other changes using the Neural Engine. The system will recognize a face wearing hats, scarves, glasses, many sunglasses,⁹ facial hair or makeup.¹⁰
