This is a simple home remedy to remove excess tan or dark spots on face. This is a much safer and chemical free alternative than bleaching that is very commonly suggested in parlors in India.
When cooking potato, set aside a small piece.
Squeeze the shredded potato with fingers to extract the juice.
Apply the juice to face and neck. The juice will turn black very fast if not used immediately. So use it immediately. But like all new skin care products, do a patch test first and check if you are having any allergic reaction.
Disclaimer: Before you get angry that we are discriminating against dark skin and promoting skin whitening, please note that India is a tropical country and exposure to sun during Indian summer can cause uneven tanning resulting in dark patches on face and hands. This home remedy is just to make those spots fade and make the skin even. This is not an attempt to convert a brown skinned person into a Caucasian.
