Thank you for your question. As a Mohs surgeon, Ihave found that it is best to apply a thin layer of Aquaphor (this is my preferred ointment but Vaseline works as well) and abandage after the surgical site has been repaired and then leave the bandage onuntil sutures are removed. The Aquaphor will help to keep the site moisturizedwhich in turn will help with scarring. When sutures are removed, it is againbest to apply a thin layer of Aquaphor ointment and a bandage and leave this isplace for several more days. If, after removal of the second bandage, the scarappears dry and scabs are present, it is best to apply a thin layer ofAquaphor. However, if the scar is not dry and you do not note any scabformation, then simply apply sunblock. If you do need to apply Aquaphor orVaseline, be sure to also apply sunblock as the sun will be attracted to theshine of the ointment. The best way to improve scarring is to apply sunblockdaily and reapply every two hours. Youmay also check with your dermatologist and see if they would recommend use of aretinoid such as Retin-A (Tretinoin is the generic name) or even retinol forcollagen production and scar improvement as well as fine line prevention asthis is the number one product to use after sunscreen.
