Depending on the amount you get and the 'bothersome' factor, the only option for me is tweezering. The other methods all require several days' growth, as the hair shaft needs to be a certain length for the treatment to be effective - waxing doesn't work on short stubbles, neither does epilating, although this is great for the fine hair on the rest of the face. White hair, as you say, isn't suitable for lasering and depilatory creams only remove the hair at the surface (the same as shaving) resulting in stubbles (but less so than shaving). Had a home electrolysis device 30 odd years ago, which didn't work, so maybe I should revisit that option, but still not happy to allow several days' growth!
