Sunscreen Application (please help)

So, I need help. I watch a lot of Korean skincare and makeup stuff made by both dermatologist, doctors etc. and professional makeup artist.

The thing is - the doctors are recommending to apply a 1/4 tsp of sunscreen wait 10-15 minutes and then again apply 1/4 tsp of sunscreen. When applying, they are using their fingers.

Even though professional makeup artists use the same amount, their application technique is different. They use a sponge. They say, that by using your fingers, you make your face warmer and the makeup base is then ruining overtime. The problem is - sponge can absorb a lot of product.

So, what should I do? Is there a compromise? Or is there another application tool I didn´t know about? Please help me, someone.
