Please recommend an effective home care device for combination skin.

Lately, I often get stressed when I sit at my vanity and look in the mirror.

My skin tone is dull and elasticity has decreased.

Since I have oily skin, it is shiny on the surface but feels tight underneath, so I am stressed.

It would be effective if you received treatment at a dermatology clinic, but

It is difficult to sustain because it requires a lot of time and money.

I'm looking into managing my home care without any hassle using a device.

It is said that most home care devices use high frequency.

I saw some reviews mentioning that the downsides of high-frequency home care devices include the heat sensation lasting a long time or lingering redness.

It also seems that the sentiment that internal dryness has worsened in combination skin is being repeated.

I think I've also seen reviews mentioning side effects where the skin became sensitive due to accumulated irritation.

Were there any side effects from using a home care device for skin care?

I am curious to hear reviews and recommendations on which home care device you used to see results.
