I almost eliminated milia this way.

A small seborrheic keratosis has appeared on my right arm since the beginning of this year.
I was thinking of just leaving it alone, but maybe because it's on my forearm, I kept feeling discomfort in my daily life.
By thoroughly disinfecting with alcohol swabs, making a small hole with a needle, and squeezing out, I observed about a 90% reduction compared to before, which was effective for removal.

Originally, I had smooth arms, but over time, I developed 2 to 3 sizable milia on my right arm due to acquired causes.
I looked it up on the internet and found that acquired milia often disappear on their own, so I just left it alone, but even after 2 to 3 months, there was no sign of it improving.
The size has slightly decreased and then increased again, so I first visited the dermatology clinic, but the specialist doctor told me that milia can be simply cut out at a surgery clinic with a scalpel, so I only received guidance and did not undergo the procedure.
I looked up how to remove milia on the internet, and I found that there really isn't any special medication for it. Instead, it might be effective to puncture with a needle and squeeze it out, so I tried doing that exactly as described.
Since it is a simple removal that can be done at home, I didn't want to go all the way to the hospital for treatment.
Actually trying it, the milia on my right arm didn't completely disappear, but it has definitely calmed down significantly compared to before.

Currently, it has improved about 90% compared to when it was severe, so it is not a significantly uncomfortable level.

I thought there would be a lot of stuff inside, but only a small amount of watery discharge came out when I squeezed it with a needle, so I was surprised.
Sometimes, as I do, there are cases where acquired milia develop later in life.
Don't worry too much when it appears; if you disinfect it well and squeeze it out, milia can improve significantly, so it's good to keep that in mind.
