Will using a reapplying sun stick still provide UV protection?

My skin is on the darker side, so I'm being extra careful when applying sunscreen.

This is after applying sunscreen.

You know they say you have to reapply it from time to time.

I apply powder after applying sunscreen.

It's not easy to reapply the sunscreen I initially applied over it.

I'm reapplying it using a clear sunstick.

I'm wondering if applying a sun stick over powder foundation provides any UV protection.

I am reapplying with the AHC Sun Stick.

Airy Light & Clear UV Shield protects your skin from UV rays.

It is said to protect the skin from UV rays by forming a transparent protective barrier that is as light as air and free of white cast, with a thin and soft texture.

I use this sun stick for reapplying.

Containing serum care powder, it provides a soft, matte finish without stickiness or shine, and a plant-derived skincare complex to comfortably care for the skin.

It is a convenient sun stick with excellent, long-lasting UV protection.

It is said to be a sun stick certified as water-resistant through a water resistance test.

It is comfortable to use thanks to its excellent, long-lasting UV protection, even during long periods outdoors, so I carry it around and use it for reapplying.
