Turmeric is an amazing color corrector. Most of your scars and dark patches are purple or have purple undertones. Yellow falls on the opposite end of purple, on the color wheel. So the yellow of the turmeric cancels out the purple of the scars and pigmentation, giving you flawless, bright skin. Mix some turmeric paste with a little bit of honey and milk and apply all over your face and neck in a thick layer. Let it dry and then wash off with lukewarm water.
