Please recommend an ampoule to treat dryness.

No matter how many layers of basic skincare products I apply after washing my face, only oil sits on the surface, while my skin remains tight and feels like it is tearing apart due to severe internal dryness.

I feel like moisturizing cream alone isn't enough, so I plan to get a highly concentrated ampoule that can replenish moisture deep into the skin.

Is there a product that absorbs cleanly without stickiness while effectively relieving inner dryness?

I have sensitive skin, so I would prefer something with gentle, non-irritating ingredients. Please do not post promotional content.

If anyone who has suffered from inner dryness like me has actually seen results, please share your holy grail ampoule or useful skincare tips. I would really appreciate it.
