i got told a year for sunbeds, unless you cover the scars with plasters or similar, but sun lotion doesnt work, as its not made for sunbeds, so doesnt help on them (in other words it can still affect your scar) and two weeks after for tanning products as long as the scar is covered, again with a plaster or similar (im using my dermatix sheets to cover mine for a good old spray) xx
