The key to sun care is adherence to the right amount and regular reapplication (skin care routine).

It's just like the title.
Even if it is a good product with a high blocking index, it is difficult to expect even half of the advertised effect if applied carelessly.

The most effective way is to use sunscreen and sun stick together.
As a basic step before going out, take about one knuckle of sunscreen (about 0.8-1g) and apply it thoroughly to the entire face.

If you find it burdensome to apply it all at once, it is recommended to apply it thinly twice to increase adhesion.

During outdoor activities, the barrier can easily break down due to sweat or oil, so it is essential to reapply every 2-3 hours.
At this time, a sun stick that can be used easily without touching the skin is useful.

When using a sunscreen stick, don't just lightly apply it once, but apply it thickly by moving it back and forth over the same area 3-4 times to maintain the blocking factor.
