I recommend this hydration ampoule that I would repurchase 200%.

I have really severe dehydrated oily skin, but I wanted to share this because the ampoule I recently switched to suits me so well! It completely eliminates inner dryness while leaving the surface feeling fresh, so it doesn't cake even when applied before makeup, which I love haha. I've already finished my third bottle and stocked up again! If you have oily skin but suffer from severe inner tightness, you definitely have to try this product.
