What’s one Korean skincare product that had people obsessed with your skin?

I had one of those moments last month where two different coworkers asked if I changed my makeup and I wasn’t even wearing any. The only thing I changed was adding a Korean skincare toner I randomly picked up while browsing online one night.

I didn’t expect much at all, I just added it because I heard it was good for hydration. After about two weeks, my skin started looking noticeably more even, and I honestly couldn’t believe it.

Now I’m curious what products have given other people that kind of almost “instant” noticeable result not just normal compliments, but the unsolicited “wait, what did you do to your skin?” kind of reactions.

Was it an essence? Sunscreen? Cream?

I’m trying not to add too many new products at once, but I’m really curious what Korean skincare products are actually worth it.
