In this dryer, an SOS for skin barrier recovery is desperately needed!

The skin becomes sensitive and its barrier is severely damaged due to summer UV rays and fall dryness.
Currently, my skin is extremely dry, and is accompanied by redness, inflammation, and itchiness, so I urgently need to restore my skin barrier.
We want to focus on restoring the skin barrier and returning it to a healthy state.
First of all, I would like to ask what treatment programs you offer that can help restore and strengthen the skin barrier.

And what are some effective, over-the-counter moisturizing/soothing products that can help regenerate damaged skin while minimizing irritation, and what types of products should I use?
What are some bad habits in daily life, such as washing your face or showering, that should be avoided to restore your skin barrier?
Please give me some advice on how to manage indoor humidity and water intake to help the skin heal itself and restore the skin barrier.

Enjoy your meal and please reply.
thank you!
