Ampoule recommendations for oily/dehydrated skin

Hello, today I would like to recommend two ampoules.

1. This is the new Innisfree Vita C Green Tea Enzyme Blemish Toning Serum. I have been using it for a week. Actually, they say you need to use Vitamin C products for over a month to see results, but perhaps it's just my imagination, but my dark circles seem to have faded after just a week. Make sure to test it on the back of your hand before using it! Some people say it stings.

2. This is Hersteller Little Drops I'm Ready. I use this along with my basic skincare routine. The advantage is that it never causes breakouts on my skin. Since it doesn't have any major distinguishing features, I recommend using it as a cost-effective option.
