Concerns about dry skin

My biggest skin concerns these days are internal dryness and fluctuating skin condition. Even though my skin looks fine on the outside, I constantly feel a tight, dry sensation deep inside after washing my face. As time goes by, my makeup tends to cake or dead skin cells become more noticeable. In particular, during seasonal changes or when I am exposed to air conditioning for extended periods, my skin becomes sensitive, and even products that usually suit me sometimes feel stinging.

Also, as my skin has become more sensitive, it turns red or breaks out even with minor irritation, making it difficult to manage. While I used to worry about oiliness, lately I feel like my moisture and oil balance is off, so I'm really struggling to decide which products to use. That is why I've been focusing on products with gentle ingredients and sufficient moisturizing power, while paying the most attention to maintaining a healthy skin barrier. Could you recommend a good beauty device? I am currently using a beauty device I bought cheaply on AliExpress, but...

I am willing to purchase a better beauty device if one is available.
