function of both formulations remains same,just to clean your skin.but ofcourse facewash & bodywash with ph around 5.5 do not let your skin become dry after using them.these formulations are more popular as they are cosmetically more acceptable.
No face wash can make your skin fairer. Suntanning is the one of the major reasons that makes your skin darker. Use sunscreen with spf-30 when you are out (9am-5pm). Have nutritious diet
I don't like listerine personally speaking. It has alcohol as a content in it. You may go for regular chlohex plus mouthwash dilute in water rinse two times a day for 28 days only.
There is in ayurveda mention pinda swed. It is a type of swedan karma [phomentation] but it do some another manner.
1. Boiled a rice in milk then take this rice in one white cloth then tied it properly and warmly it rub on your face every morning for 15 days then stop it and do next month again 2. Apply almond oil on your face and massage for 3-5 min at night.
By doing above thing you will get good result.
