Hi. I would suggest you the application of a cream by name MELAS . It is an ayurvedic cream which helps in reduction of dark patches.
Application : While using for the first time squeeze out required / small amount of cream and apply gently on affected area for 5 min using your finger tips, to check for irritation. If no irritation is seen this application may be left overnight.
Note : Though the cream has no side effects it is known to peel of the affected area in small layers (painless) so it is best used at night and only on the affected area.
Time Span : Time taken to respond to certain product differs individually, hence predicting the same is not possible. However on continued use for a month and amount of result seen in the same, may prove to be helpful in deciding the time taken on the whole.
Other Suggestions:
Potato juice, Tomato juice, Lime +honey+glycerine are best know agents to reduce a dark Patch/ Bruise
Olive oil,
Vitamin E oil, Vitamin E Capsules ( by the name
EVION - you can puncture the capsule and use the gel within, as a night time application) can also be used.
If your nose bridge is prone to such bruises you may want to try for
contact lens if its advisable by your Ophthalmologist/ Optometrist.
Hope this has been helpful. Have a great day
