There used to be a time when if you wanted Korean beauty products and you lived in the U.S., your best bet would be shopping on YesStyle or Stylevana. Now, Rom&nd is in Ulta and K-beauty products are on sale for Amazon Prime Day.

As a shopping reporter in her fifth year covering Prime Day, someone who regularly tries out new skincare (and skincare tech), and someone whose algorithm is deeply locked into new Korean beauty releases, I feel uniquely qualified to call out some of the best deals from the sale. Plus, with one of South Korea's largest beauty retailers now in the U.S., there are more products than ever available — which can make sorting the duds from what actually works even more challenging.

This collection of deals in particular comes from my tried and true recommendations — products I have bought (and repurchased) with my own money. If you have acne-prone, oily/combination skin that can lean on the dehydrated side, this post is especially for you.

That said, it's worth mentioning that there's no product that's a miracle balm for everyone, but I curated this list to include at least a few products with more universal appeal. Without further ado, here are my seven favorite K-beauty products on sale during Amazon Prime Day.

The best mascara

The best mascara I've ever used is under $10 currently, and I did repurchase my fifth tube during this sale. I have very straight lashes and oily eyelids, which isn't exactly a recipe for success with most mascaras. This one, however, holds my curled lashes ALL DAY, with very minimal smudging. It does, however, take an especially strong remover to get it off (but I can confirm a rec lower on this list will do the job).

A savior for chronically chapped lips

The thing about my lips is that they will be dry, no matter how much water I drink. I've tried many a viral lip balm that's done next to nothing for them, and many a lip mask that's worn off hours before I wake up. The CNP lip butter is the opposite of that, providing a thick layer of moisture that lasts all night long.

A moisture serum that's a dream for texture

I've tried my fair share of serums, but none have transformed the texture of my skin like this IUNIK Beta-Glucan one. At $12.33, it is a steal and a dream if your oily skin is dehydrated, but very particular about how it gets its hydration. A bottle lasted me at least a couple months of daily and nightly use.

Nina Park approved blush

If you follow any sort of beauty content online, there's a chance you came across the term "Nina Park makeup" in the past six months. It's code for makeup that's effortless, lived in, but still noticeable. The artist used this Clio blush on her celebrity clients, and with its gorgeous glow and soft from-within flush of color, it's easy to see why.

The Goldilocks gentle cleanser

When I say I want a gentle cleanser, I mean I want something that won't strip my skin. However, I still want it to actually clean my skin. This beplain cleanser does exactly that — I stocked up on the full and travel size during this Prime Day sale.

A cleansing balm that's not too heavy

If you're a freak like me and love a double cleanse (I want everything off my skin at the end of the day), this Dr. Althea balm is the way. I especially love the grinding cap, which means I won't be dipping my contaminated fingers into the balm every time I need to use it. Bonus points: it can remove the Clio mascara.

Glow in a bottle

This was the viral product that got me the fastest — I saw, like, two people use it, and suddenly it was in my cart. Thankfully, it was the right one to bet on. I spray this stuff on myself, but I've also spritzed my dry-skinned friends on days they complain of feeling especially desert-like, and guess what? We all love it. This is my secret when I over-powder my makeup, when my under-eye concealer starts to get crusty, or when I simply need a little refresh.
