>Suppose that none are below the dermis
it still depends on a lot of factors and it's mostly genetic. all my white scars in picrel are at least a couple years old and most were dermis, shallow fat at the deepest. i dont see them going away any time soon and havent looked any different for a long time. typically on thighs they heal smaller but they'll still probably be visible for a long time
for whatever it's worth i've never tried any topical treatments, you may find they may work for you.
