Can I resolve millet-sized acne with home care?

As I age, dyeing my gray hair has become essential. My strength is gradually declining, and now my skin is also causing trouble.

I've lived hearing that my skin is good, but I'm upset.

I have small pimples on my forehead.

I wonder if it's because of my bangs, so I keep my bangs completely back at home, but it doesn't help.

It seems that just a clean wash isn't enough to solve the problem.

Dermatology treatments can't be done in a single session, so the cost was a bit burdensome.

Is there a way to alleviate milia (whiteheads) through home care?

I feel so stressed every time I look in the mirror.
