Bath bombs have a best before date, and after that point, it stops fizzing. The chemical reaction between baking soda and citric acid is what makes the bath bomb fizz and move around the bathtub, so when these ingredients are no longer potent, the bath bomb will stop fizzing.

No one wants to use expired bath bombs on their sensitive skin as it could bring about irritation. An expired bath bomb will show signs like discoloration, having a rancid smell, or significant mold growth. Old bath bombs also lose their ability to effervesce when dropped in the tub as they lose carbon dioxide gas.

Smells: Old bath bombs that have passed their expiration date might begin to have a chemical smell or have that rancid smell. If it has a weird smell different from its natural fragrance, then you should halt using it.

The constituents mentioned are the real reason a bath bomb fizzes. If your bath bomb doesn't have any fizz in it, it is likely that it doesn't work as well as it should. So, don't use it to avoid being disappointed.
Discoloration: With time, bath bombs are known to change their shade or fade in color. The more faded your bath bomb looks, the more you are certain it has gone past its expiry date. It is important to note that you should not use a bath bomb that has really faded as it can irritate your skin.
Mold: Can mold grow on bath bombs? The short answer is yes. Mold growing on your bath bomb is a great sign that it is way over its expiry date.

This can also happen if your bath bomb has been exposed to oxygen, mold spores, or water.
Use an expired bath bomb at your own risk. It is generally not a good bet to use any product that has gone bad as you don't know the chemistry behind their production and how it could impact your health if you do end up using it.
