I have learned that every form of eczema has variations and exceptions. GD is also described as being attributed to mostly to males and yet look at how many of us bloggers are women! Perhaps years ago when men spend much more time in the sun as farmers and women stayed inside doing the domestic chores GD developed in more men. In the past women might have listened more to their grandmother's warning about skin spots and damage, yet my generation believed a tan was beautiful. Today women spend hours outside from an early age; I did and still too. (Today I cover up to protect my skin).
Today we are all exposed to substances never put in our enviroment years ago. If I was a prairie wife even 100 years ago I would never have been exposed to the substances that am allergic to today. With repeated contacts our bodies start to fight back and raise up our histamine armies trying to protect us from substances they believe are harmful. You may not have Allergic Contact Dermatitis,ACD but who knows if AD is caused from your immune system rejecting your environment too. Many are born with up AD, but why? Their mother's have been exposed to substances and perhaps it passes on to the child.
AD. I would sure check out Dupixent.
If you start a discussion asking for those with AD to share what age they developed AD you will find out for yourself that there are many that got it later in life. Must also be some Google search where you could check that out. If you are Medicare age I believe this expense drug is approved.
