Easy Access: Jars allow users to easily scoop out every last bit of the product, minimizing waste. There's no mechanism that can clog or fail.
Control Over Dosage: Users can take as much or as little as they need, which is particularly useful for rich creams where a little goes a long way.
Versatility of Use: The wide opening makes it easy to use the product on different parts of the body (e.g., face, neck, décolletage) without contaminating the main container.
