Please introduce an ampoule that helps with a dry skin barrier.

With the arrival of winter, my skin around my chin and mouth has become a complete mess, covered in bumps, perhaps because my skin barrier has been damaged. Since I have extremely dry skin, autumn and winter are indeed the times when my skin is at its worst. However, I am not sure if it is due to the dryness lately or if my skincare products don't agree with me, but it feels like my skin barrier has completely broken down.

The first thing I notice is that when I apply foundation after my basic skincare routine, it doesn't adhere well and feels like it sits on my skin. Since my skin condition isn't good, I'm getting breakouts that I didn't used to have, and the texture around my chin and mouth feels rough and bumpy to the touch. I've also been feeling a lot of internal dryness lately as the weather has gotten colder, so my skin feels tight by the afternoon. These days, even sunscreen feels heavy, so I only apply the lightest product possible and go to work with practically no makeup on.

I am currently using lotion and cream as highly moisturizing products, but I feel that a high-performance ampoule needs to be absorbed first for my skin to be stably hydrated. Since my skin is so dry, I prefer fluid, watery products over oily ones because they absorb well. I apply toner multiple times, but because my skin is so extremely dry that it absorbs instantly, it feels like it isn't enough no matter how many times I apply it. Autumn and winter are such difficult seasons for extremely dry skin.

I am very curious about what ingredients are good for restoring the skin barrier, and I would appreciate it if experts could recommend some ampoules that are effective for this purpose. Since I have sensitive skin, products that are too irritating tend to sting. Please recommend an ampoule that is gentle, soothes the skin well, and can strengthen the skin barrier.
