What is the most important item for home care?

From basics like toner and lotion to various beauty devices

There are so many home care products these days, you know.

What do you think is the most important item among them?

I still think the basics, like toner, lotion, and cleansing, are the most important.

Actually, I don't think you can see a dramatic effect.

Should I focus more on functional essences for wrinkles and whitening?

Or would a single device like a high-frequency massager be all you need?
