Do you have any tips for glow makeup that doesn't clump?

I find that glowy products tend to clump easily.

I'm not particularly good at makeup, but when I watch people do it on TV, I get the impression that it applies thinly and nicely.

I'm not sure if it's the product's fault or if I lack the skill, but I've been experiencing clumping, so I'm taking this opportunity to look into it properly.

I'm having trouble applying glow makeup products, perhaps because the application technique is more difficult. Please give me some help.

I'm wondering if using a tool with a non-clumping tip is better, if using my hands is better, if body temperature is important, and so on. ㅠㅠ

Ah... so the basics might be the problem, right?
