Has anyone tried the Etem pore pack for whitening?

I am usually very interested in whitening.

As a result, related products for shorts occasionally pop up.

Among them, the product that stood out was the Etem Pore Pack.

There are many reviews saying that because it contains charcoal, it is good for pore care and has excellent whitening effects.

The price is quite reasonable, so I'm interested. Has anyone tried it and seen whitening effects?

I'm curious about the real reviews.
