Ask an Eye Doctor and Get an Answer ASAP
What were the symptoms that got you started on the cream? What type of cream is it?
Sometimes the preservatives in cream and ointment can cause irritation and redness after you have been using it for a while. It seems prudent to stop it at this time. You may need a weak steroid cream to ease off the irritation and redness. Cool compresses may help also. But you may need to see an eye doctor to get some steroid ointment/cream for it.
As for the original symptoms, dark circles under eyes and puffiness may be allergies or lack of sleep. However, more often it is caused by thin skin and blood vessels leaking underneath. It seems that lasers or peels tend to work better than OTC creams and ointments.
I hope this helps and thank you.
