I would appreciate it if you could recommend a skin barrier toner.

The cold winter is approaching. As the weather gets colder, I would like to be introduced to products that are good for the skin barrier. Especially during the transitional season like now, with its drastic temperature fluctuations, the skin barrier becomes very vulnerable. This seems to intensify even more as we age. That is why I want to receive recommendations for products that are effective for the skin barrier. With the severe temperature swings and the aging process, my skin's ability to adapt is diminishing, and the elastic, soft skin I had in my 20s seems to be disappearing. I need a cream and toner that are effective for this skin barrier. That is why I am asking you to recommend products that are good for the skin barrier. It is all too obvious that once the cold winter begins, my skin will suffer even more. Because my skin is so dry and rough, I need a skin toner, which is the most basic foundation. If you can introduce me to good products tailored to my specific skin type and skin barrier needs, I think I will be able to get through this winter well. However, I have also been using various products, switching between this one and that one. However, I have tried various products that are suitable for my skin and do not cause allergic reactions. While doing so, I did find a few products that worked well for me. But finding products even better than these seems to be my top priority. This is because as I get older, my skin becomes dry and rough, and that soft, matte finish is disappearing. Therefore, I would like to ask you to recommend better products for me. I would like to be introduced to a toner and a cream that are good for the skin barrier and suitable for skin barrier health. Finally, I would like to introduce the toner I am currently using and ask for recommendations for products that are even better. I would appreciate recommendations suitable for my skin barrier during the winter season.
