Carmex is not made of whale sperm.
Carmex being made of whale sperm is an urban myth and untrue rumor.
However Carmex does contain beeswax which is an animal product so Carmex is not vegan and also Lanolin.
Other ingredients in Carmex are menthol and camphor.
The camphor and menthol give Carmex a cooking effect that helps to relieve irritation of dry lips and encourage a healthy appearance which feels good and looks good.
In some people that use Carmex allergic reactions may occur and appear as blisters, redness, or cracking of the lip's surface.
If you have an allergy to a specific ingredient in Carmex, then you should not use Carmex.
You can instead use Vaseline or other petroleum jelly to help seal in moisture and protect your lips when you can't use Carmex.
You can also put Carmex on your face and reduce the appearance of redness and help with chapped skin on your face.
Lip balm including Carmex is a good way to reduce skin redness on other areas of your body and not just your lips.
