Tiny, colorless bumps on hand

I started having these tiny nodules two years ago during the Covid pandemic, after using a lot of hand sanitizers. It spread out on my hands, including palms and knuckles. They are never in cluster, each as an individual nodule. They are not blister, and not itchy. They are usually more obvious after I showered.
I could not find a name for them and eventually went to see a dermatologist because I was afraid that they were warts.
However, the dermatologist neither confirm that they were warts, nor did any lab test. She burned most of them off, but missed some. I was told to go back to see her if/when there were more.
Seeing a specialist to burn off bumps whenever I see them - is too expensive an option.

I started to become paronoid and constantly washing hands and air dry. I am afraid to spread them around, in case they were warts. I spent an extra half hour in the shower scrubbing my hands. I have been soaking my hands in vinegar for 15 minutes every night for over a year now. When my skin started getting thin, and soaking in vinegar hurts, I dilute the vinegar to 66% of its strength.

I still have them, just not as many. I wonder if I can ever stop soaking them in vinegar? I am also afraid to use lotion. Today, I came across this term Keratosis Pilaris - but found out that it does not occur in palms because palm has no hair follicles.

So, I am back to square one. I am getting so tired of these tiny bumps. Please help. Thanks.
