Using this hand cream is easy. Just squeeze a small amount onto your palm and rub it evenly over your hands until fully absorbed. You can use it as often as you like, especially after washing your hands. As for storage, keep it in a cool and dry place, away from direct sunlight. There are no strict usage limitations, but if you have extremely sensitive skin, it's advisable to do a patch - test first. With regular use, you'll notice your hands becoming softer and more moisturized.
