Do you remember the 7-skin method that was popular a while ago?

There's a beauty comic I used to read, and in it, they used something called the 7-skin method.

There was a product that worked like a skin pack where you just patted it on number 7 in the morning.

I've been thinking about this lately.

A friend recently sent me a YouTube link, and it seems like they recommend applying skincare with a makeup sponge these days.
