Please tell me some home care recommendations.

My skin has been in bad shape lately, so I'm trying to take care of it at home, but choosing home care products is harder than I thought.

There have been more than a few times where I bought a home care product after seeing an advertisement on social media claiming it was a recommended product, only to end up wasting my money...

Right now I'm just using a sheet mask, but are there any home care products that are more effective?

The device is good and the cost-effective ampoule is also good!

Please share just one home care recommendation that you would definitely use at home!

My wallet is too small to go to the dermatologist right now;;ㅋㅋ

First, I would like to try home care, so if you could let me know in the comments, I would really appreciate it~!
