I have been using spects for 12 years. There is skin discolouration on the both sides of my nose and on the bridge of the nose. Which oinment to use?

Hydroquinone. This is a cream that bleaches out pih or " post-inflammatory hyperpigmentation". The areas of increased pigment on your nose have developed because of years of low-lying inflammation that has occurred secondary to the glasses rubbing in that area.
