Please give me tips on how to maintain moisture.

When I apply a moisturizing product after my basic skincare, it feels incredibly hydrating at the time of application, but

It doesn't feel like it's absorbing into the skin, but rather like it's resting on it.

So when I wash my face or after some time passes, I feel like it hasn't moisturized at all.

If you have any tips, routines, or products to keep your skin moisturized for a really long time, please recommend them!

As I get older, I care so much more about my skin than whether I look pretty or ugly. It’s getting drier and blemishes are appearing, so it really bothers me.
