I'm looking for advice on effective prevention and restoration methods for skin barrier breakdown!

hello
I feel like my skin condition is getting worse.
It seems that the change of seasons, age, and poor skin care habits all work together to cause the skin barrier to break down.

Currently, the skin is dry, has persistent redness, feels itchy, and is sensitive to even the slightest irritation.
I personally think that this might be a sign of the so-called breakdown of the skin barrier.
I would like to know an effective way to improve the current condition of this skin barrier breakdown phenomenon and restore the skin.
I feel like self-care alone is limiting, so I would like to seek professional advice.
I don't know how to do it, so I'm just applying additional moisturizer.
Are there any special things to be careful about in your current situation, such as washing and exfoliating habits that you absolutely should avoid in a state where your skin barrier is broken?
Are there any moisturizers that contain key ingredients for restoration?
I would like to hear your opinion on the procedure and treatment.
If there are any special precautions to take before the procedure, please let me know.
I would like to ask for advice.
