Sunscreen should be applied to the area as sun exposure speeds up fading. Lips that have been done should have a lipscreen of at least SPF 30 as well.
Before swimming, apply petroleum gel to the brows to prevent chlorine from penetrating the area and to impede fading. Rinse the area after exposure to chlorine.
If you are to have an MRI, inform them that you have cosmetic tattoos.
Cosmetic lasers can discolour, lighten or darken the area. Inform the technician to avoid the areas. The same goes when getting a chemical peel, the area should be avoided.
