Please recommend some affordable skin ampoules.

My basic skincare products are running low, and since it happens to be the Olive Young sale, I plan to take this opportunity to buy an ampoule. As a student, I simply can't afford department store brands that cost over 50,000 won, and

I am posting this question on the community because I would like recommendations for effective skin ampoules under the 20,000 to 30,000 won range.

Since I have combination skin (oily T-zone, dry cheeks), I can't use textures that are too sticky or heavy because my makeup slides off the next day. Do you happen to have any recommendations for a miracle skin ampoule that absorbs quickly and freshly while effectively relieving inner dryness?

My friends use Goodal or Tory a lot, but I'm worried because they feel a bit dry to me.

I'm buying this on my part-time job earnings, so I really don't want to fail. I would be so grateful if you could leave lots of comments recommending the ultimate value-for-money skin ampoules! I want to get glowing skin and look like a campus goddess!
