Should I worry about the skin colored papules on my son's nose?

Hi doctor,

My 2.8 year old son has got two tiny skin color papules on the dorsum of the nose. It will not attract one's attention on a casual look. He has the same for more than a month I guess. First, I thought it might be due to sweat. Because, it looks like sweat dots over the nose. It is not itchy and there is no redness or dark circle around. It is not a fluid-filled one. There is no other rash or papule anywhere in his body. He started his Montessori a few months back. In the last three months, he got severe cold, cough and fever thrice. Now, he is normal. I am currently giving him Zincovit and Calcium supplement daily.

Please suggest me some advice.
