The war against sweat begins. Please tell me how to increase makeup longevity.

I get hot easily, so when I start sweating, I know summer is coming.

On top of that, I've been sweating even on humid days, so I've been going through hell these past few days.

I'm actually worried about my makeup now to the point where I carry a handkerchief to wipe away sweat.

I don't usually do touch-ups, and since it's a hassle, I used to use oil-control powder or setting spray to avoid doing them.

However, since there have been days where sweat streams down my forehead, touch-ups seem to be essential.

How do you touch up your makeup on sweaty skin?

I'm trying to wipe off some sweat and apply cushion foundation right now, but it seems a bit clumpy, and since there is already powder or setting spray on, I'm not sure how to handle this.

Or if you know of a makeup technique that lasts longer even with sweat, please share it.

I do use primer or fixer, but I'm not sure about the staying power.

I'm also looking forward to recommendations for long-lasting fixers.
