Wash the peel from the quince and place it in the vodka. Leave it for two weeks. At the end of that time, pour in the rosewater. If your skin is dry, you can add more rosewater.
It can be kept in the fridge for two weeks.
Pour a few drops of the mixture on a cotton pad and dab your neck, without pulling the skin. Then give little, light pinches on the skin all over your neck and finish off with a moisturizing cream.
Plain rosewater is also good for eye compresses.
