An easy remedy for diminishing pimples.
Take a few(1 or 2) tender leaves of guava tree(Guava-Peru/Pera/Amrood/Koyya) and crush them in a stone pestle or simply between your hands. Make sure not to lose the juice of the leaves, because that is the real essence.
Take about 1/2 teaspoon of turmeric powder. Normal turmeric works fine, but if you can get Kasturi turmeric, then nothing like it.
Mix both these to make a paste. You may find clumps in between as the leaves may not be fully crushed, which is fine. Apply this mixture on face and leave for about 15 minutes. Wash away with fresh water. You can repeat this treatment twice a week.
This pack not only helps in preventing pimples, but it also helps diminish the pimple marks. As such, the guava leaves and turmeric do not have any side effects. But please do remember to do a patch test before you use it on face as people may have different reactions to various ingredients.
