Mohs surgery post stitch care, should I keep putting Vaseline on the scar after the week is over?

Thank you for your question.  I’m
glad to hear that the area has healed. 
It has been my experience that use of Neosporin can cause an allergic
reaction as a large percentage of our population is allergic to one of its
ingredients – neomycin.  I have also
found that once scars are no longer scabby or crusty, the use of Vaseline or
Aquaphor is not required however, it is best to follow-up with your Mohs
surgeon for recommendations. In order to minimize scarring, it has been my
experience that the use of a zinc oxide or titanium dioxide based sunscreen
applied throughout the day to all sun exposed areas is the first step in scar
reduction.  Even better for scar
minimization is use of a silicone based product with sunscreen. Again, it is
best to follow up with you Mohs surgeon for their recommendations.

Thank you for your question.  I encourage all patients to use either Vaseline or Aquaphor for at least 2 weeks post procedure. Keeping it moist provides a healing barrier and allows the wound to stay somewhat protected without a bandage.  After the two weeks it is your choice. Regardless, you need to apply a moisturizing cream on the area along with sunscreen .  Best,Ariel Ostad MD PC 

Your choice. It's not necessary to keep applying the Vaseline, but if it offers you some benefit, you can certainly continue to use it.
