Common triggers of atopic dermatitis or eczema flare-ups

You might be thinking that your atopic dermatitis is purely triggered by the world around you. You may have noticed that you sometimes experience flares if you change your laundry detergent or simply when the seasons change. So, it's understandable you could naturally assume that these things are the root cause of your AD. But this isn't necessarily the case.

You see, even when your skin looks clear between flare-ups, the other underlying causes of your AD (over-activity in your immune system and genetic factors) are still at play.1,2 As a result, there's continuous underlying inflammation beneath the surface of the skin, even if you can't always see it or feel it.2


A trigger could be something that sets off a flare.3 Even when you've tried your best to identify and avoid your triggers, flares can keep on happening and your AD can, unfortunately, still be there.2,3

This can be frustrating, but it's important for you to remember that this isn't because you're not doing well enough at managing everything that could possibly set it off. Avoiding certain triggers may help to stop some flare-ups from occurring in the short term, but there are still underlying factors at play that are harder to control.3,4 So that's why changing your lifestyle around your AD may not always help you gain long term control.5


You shouldn't have to miss out on the life you want because of your AD.

Triggers in more detail

It can be hard to identify what might be triggering your AD, as triggers vary from person to person.3 There may also be a delay between being exposed to a trigger and you experiencing a flare-up, so it can be difficult to make the link to what's triggered your AD.3
