Can kissing cause an allergic reaction?
It’s not the kiss itself but something involved in the kiss that is probably causing your lips to itch and swell. Lipstick or lip balm, food that may have been consumed and that lingers in the saliva or on the lips, can also be causing the reaction. Even if the person kissing you brushes their teeth, saliva can still contain the allergen for up to 24 hours.
If you struggle with allergies, make your new partner aware of the specific allergens
