Up to how many essences, serums, and ampoules do you apply?

I have a lot of cravings for ampoules, serums, and essences... haha

In addition to what was taken and uploaded as a photo

I think there are at least 10 more lol

The product I uploaded in the photo is the daily ampoule I mainly use. I find that I end up applying up to four by the time I apply one, let it absorb, and then apply another. It doesn't feel sticky on the skin either.

But I'm getting curious... I wonder how many tubes other people apply haha.

I also wonder if I'm applying too much, haha.
