Sun exposure
Your child should avoid direct sun exposure after a surgery. Exposure to the sun of a surgical scar that is healing (still red or pink) can cause permanent darkening. If the new skin gets tanned, it will not fade and will remain a dark colour.
Use a sunscreen with SPF 30 or greater that has UVA and UVB protection on the surgical scar when your child is exposed to sunlight. Your child may also use a sunhat, long sleeves, or a rash guard to cover the surgical scar when in direct sunlight.
Once scars are fully matured, there is no risk of the scar retaining pigment. Scars mature within about 18 months from the time of surgery. Your child’s scar will be considered mature when it is pale and mostly flat.
Activity
Your child may swim in pools or lakes if the surgical scar has completely healed. There should be no stitches in place, scabs, or open areas when your child resumes swimming.
