all i know is...the vernis is very sensitive to chemicals so avoid touching it after putting on make up, perfume etc. even to sunlight and heat.i have no idea how u cud get d lustre back. i hope it helps too
Please don't put olive oil on your Vernis Alma. Are you near enough to the boutique to ask them what you can do about it? I have one, too and I make sure my hands are oil/lotion free when I touch the handle. If all else fails, I'm sure you can get the handles replaced (of course they will prolly charge you for it).
