Everyone’s skin has its own healing process and duration. It is recommended to apply ointment as long as the skin is still scabbed, and even after. The ointment will help your skin regenerate faster and better.
AVOID water (for the PMU area), makeup, excessive sweating, sauna, pools, sunbathing, do not PEEL the scabs at all (you may cause scarring if otherwise).
Do NOT apply anything besides Aquaphor ointment such as Vaseline, antibiotic creams, Neosporin etc. Grapeseed oil may be used to substitute Aquaphor.
During 4 weeks after the procedure it's better to not use creams that contain acids or ingredients that will lighten or exfoliate the skin.
