Take 1/4 dose of Benadryl. You DO NOT NEED a full dose. A super minimal dose will reduce the stress the skin in that area is feeling but will not effect the rest of your system. I buy Children's Benadryl liquid at Walmart. Their brand will do just as good. I would take 1/2 teaspoon and no more. If this works then you know that's the maximum dose you can get by with.|
Benaryl is a strong medication for extreme reactions to an allergen so it's not to be taken lightly, it is a strong medication.
If you take a full dose you will dry out, wheeze due to no moisture being in your throat and lungs, and won't have any mucus.
I also suggest you clean your face totally of all makeup, take a long hot steamy shower and wash your face again, use a clean towel when you get out to dry your face on, even one that has just been sitting there may have the same allergens on it that are in the air of your home. Then perhaps see how today goes and if not wearing any makeup or lotion or any hair products helps your skin not itch.
You can develop an allergy at any time. Even if you use the product every day. I have developed an allergy to something in conditioners. I feel like I am pouring acid on my scalp when I put it on.
