Answer:
I think toothpaste requires more preservation as compared to lotions.
Explanation:
- Toothpaste mostly has fluoride in them which starts breaking down as time passes.
- Such toothpaste is more likely to have less defense against bacteria so it is recommended not to use expired toothpaste.
- While lotions mostly include synthetic and natural preservatives which give them a longer shelf life as compared to toothpaste.
