How do I fix a lipstick print on a signed photo?

[Friendly collector]

Hey, guys!
I have a "kissed" autographed photo (a photo - quality photographic paper - with a lipstick print on it ).
How do I fix it to make the lipstick print last forever?
I need to fix the lipstick print or it will smear and disappear!
Do you have a valid treatment or product to suggest?
Thank you for your help!

Why don't you cover it with the thin sticky transparent plastic stuff you can get. An then maybe frame it. Not sure what the stuff is called, but I'm sure someone on here knows.

Artists use hairspray for smudgy pens, pencil, chalk, pastels etc, there are also proper artists' fixatives on the market. If you start off having a Google for hairspray and fixative you will hopefully hit upon one which will work. You may want to get another photo kissed by someone wearing lipstick and test that before applying anything to the kiss you want to preserve.

Good luck

NOOOO!!!!

The question was how to fix it on the photo, not to get it off - acetone will remove it.
