Skin type becoming increasingly dry

When I was young, my skin was sensitive, so I was very itchy and prone to breakouts; therefore, I was very careful with the cosmetics I used.

However, as I became an adult, that feeling somewhat disappeared, and I found that most cosmetics were fine.

Recently, however, my dry skin seems to be getting even drier.

Even in the middle of summer, I feel like I'll go crazy if I don't apply body lotion or facial moisturizer.

Everyone tells me I'm overreacting.

Everyone is surprised when they touch the area where they applied lotion and the area where they didn't.

It doesn't look that dry on the surface, but if you touch the areas where you don't apply lotion, it feels quite dry, contrary to how it looks...

You said you understood why I apply lotion so thickly even though it's so hot.

How on earth can I get rid of this increasingly severe dryness?

I'm drinking plenty of water and making sure to apply lotion really well.

I'm using various ampoules too, but I'm not sure...
