We hate blemishes on our skin either face or neck. Don't we? The tip I have is from my grandma.
You would need:
Lime or lemon juice - a few drops
Raw Honey - 1/2 tsp
Turmeric - a pinch
Mix a few drops of lime/lemon juice, with 1/2 tsp of raw honey and a pinch of turmeric (optional) and apply it to your skin regularly. Leave it for 15 mins before washing.
