I have four of these exorbitantly expensive Guerlain Rouge G lipsticks. [Don't judge! They were bought on sale, mkay?]. I’ll do a separate blog post on them eventually, but this article is on the possibility of refilling them.
There has always been rumors that Guerlain will be making refills for these Rouge G lipsticks, which they should since the case is too luxe to not be re-used. So I thought to myself that by design, these lipsticks should be easy to replace. I fiddled a little on one, and off came a tube. It is then easily inserted back in. I tried swapping the tubes amongst my Rouge Gs and they are interchangeable. As always, click on the pictures to enlarge.
So bottom line, technically you can replace them, though I haven’t tried it yet with the Guerlain Rouge G refills and testers being sold on Ebay and elsewhere. If you’ve tried it, let me know how that worked for you.
