How many skincare products do you use in the summer?

My skin is sensitive, and I especially dislike layering up in the summer, so I'm trying to minimize my application.

As I get older, I'm starting to worry about freckles and blemishes, and I feel like I need to pay more attention to moisturizing than before...

I'm curious how many steps and products others use in their summer skincare routine.

When I'm at home, I sometimes don't apply anything at all during the day, or just use toner.

Since I have to wear makeup when I go out, I make sure to apply toner, lotion, essence, and sunscreen, even if just thinly... but I wonder if there is any way to reduce it or if there is a way to solve it all at once...

Even if I'm at home, I should still apply it, right?
