Are there any moisturizing products for severely dry skin?

My skin is so dry that when I was young, people often said it felt like it was going to crack in the winter. Back then, there were no moisturizing cosmetics other than lotion. It wasn't until I became a young woman that I started using toners, lotions, and nourishing creams. I didn't even know what sunscreen was. However, perhaps because I am naturally so dry, no matter what I applied, the relief was only temporary, and my skin would dry out quickly. Winters would become frighteningly dry, so I practically lived on cream. Now that I’m older, not just my face but my entire body is so dry it feels rough and brittle. I literally have "severely dry" skin. Even though I rarely wear makeup, I have bought and apply all sorts of moisturizers, but the problem remains unresolved. Are there any moisturizing products that would help with severely dry skin like mine?
