Vitamin E oil naturally promotes lash growth, and its oils can dissolve dried mascara. If your mascara hardens, add two drops of vitamin E oil, shake well, and it will restore its consistency. Olive oil or baby oil can also substitute for vitamin E oil.
Eye Drops Method
This method is also simple: add two drops of eye drops to the mascara and shake well. But remember not to add too much, as it will eliminate the mascara's waterproof properties, potentially causing smudging.
Hot Water Method
This is the simplest approach. If you don't have many items on hand, use warm water to "revive" your mascara. Prepare a pot of hot water and pour it into a large container. Then submerge the sealed mascara tube for about 3 minutes. You can also soak it longer, which will soften the dried mascara further, making it easier to apply.
Perfume Method
Simply add a few drops of perfume to your mascara.Remember to use just two drops. This works well, but consider the perfume's cost—using expensive perfume on inexpensive mascara isn't worth it. Also, avoid this if you have sensitive eyes, as the alcohol in perfume may irritate the skin. If you prefer not to use perfume, replacing it with toner is another good option.
