I'm worried because I have bumpy rashes not only on my face but also on my arms and neck.

I have been under a lot of stress lately because of my skin. Tiny, bumpy spots have started appearing in my facial pores, and the strange thing is that it's not just my face; similar ones are popping up one by one on my arms and neck as well. They aren't red, inflamed, or particularly painful, but when I touch them, the texture feels rough and I can feel small granules like goosebumps, so it keeps bothering me.

At first, I thought it was just dead skin buildup, so I moisturized diligently and even tried peeling products, but there wasn't much change. It seems to get better for a few days, but then the bumps keep popping up again; this cycle repeats. Especially when I wear makeup, my facial skin texture doesn't look smooth, and I can see small bumps on my arms and neck up close, so it bothers me even more in the summer.

I searched online and found some mentioning keratosis pilaris, while others suggested it could be closed comedones caused by sebum or dead skin cells, which makes me even more confused. I am curious if it can occur on the face, arms, and neck simultaneously, and I would also like to know if it can be improved with home care alone.

I am refraining from touching or squeezing them because I am afraid it will only lead to hyperpigmentation or scarring, but it keeps happening, which is frustrating. In this case, what kind of treatments or care at a dermatology clinic would be helpful? I would like to hear from those with experience on whether I need procedures like skin boosters, lasers, or peels, or if improvement is possible with just consistent moisturizing and exfoliation. If anyone has had similar symptoms and saw improvement, please advise on which methods were effective.
