(Purchased with my own money) I recommend this pore ampoule.

It's the Skinfood Acorn Pore Peptide Ampoule.
They say it is a product that tightens pores with Jirisan acorn extract.
It even features the dual functionality of wrinkle reduction and whitening.
The texture was good because it wasn't too sticky to use in the summer.
The price was 27,000 won, but I bought it cheaply for 16,200 won with a 40% discount.
I'm going to try taking thorough care of my pores this summer!
