What is your usual skincare routine?

My morning skincare routine is to apply a mildly acidic cleanser, toner, moisturizer, and sunscreen in that order.
My evening skincare routine is to double cleanse and then mix the ampoule and apply it in the morning, but my skin is still very dry these days.
If you feel very dry, microwave a towel and place it on your face to open your pores.
After applying the modeling pack, wash your face with water, add a drop of oil to the moisturizing cream, and apply it generously to your face.
But when I look at other people's skincare routines,

There are people who apply serums, ampoules, lotions, creams, eye creams, and even eye serums.
What products and order do you use in your skincare routine?

Oh, and what's the difference between serum and ampoule? Difference in concentration?
