The easiest way to use alum as skin lightening agent (and tightening) is by gently rubbing it.
How to apply
- Rub The Alum Block Thoroughly Over Your Face And Leave It To Dry
- Then, After A Couple Of Minutes Rinse Your Face With Water.
- Repeat This Process Every Week.
The above process makes your skin tight because alum removes moisture from the cells. An addition of coconut oil on the face can help you rectify the dryness caused by alum.
