How to Identify and Track Your Personal Triggers

Why This Is Worth Your Time

Living with eczema or psoriasis means learning your skin on a deeper level. Flares can feel random — but more often than not, there’s a pattern. And once you can see it, you have real power to change it.

Tracking your triggers isn’t about adding more to your plate. It’s about gathering information that helps you and your care team make smarter decisions — so your treatment plan works harder for you.

The Most Common Triggers to Watch

Before you start tracking, it helps to know what you’re looking for. Most flares are linked to one or more of these four categories:

• Stress is one of the most common — and most overlooked — triggers for both eczema and psoriasis. Emotional or physical stress can drive inflammation and worsen symptoms, sometimes without an obvious connection to a flare.
• Environment and weather play a bigger role than many people realize. Cold, dry air can strip moisture from the skin, while heat or sunburn can irritate the skin barrier. For people with eczema, allergens like pet dander or pollen may also be a factor.
• Lifestyle and diet can amplify inflammation, particularly in psoriasis. Alcohol, high-sugar foods, and heavily processed foods are common contributors. Some people with eczema also react to specific foods — though this varies from person to person.
• Illness and injury can activate the immune system and set off a flare. Infections like strep throat are a well-known trigger, as is physical trauma to the skin — things like cuts, bug bites, or even vigorous scrubbing.

How to Start Tracking

You don’t need anything fancy — a notes app or a simple journal works well. When a flare starts, try to record a few things: how severe it feels on a scale of 1 to 10, anything unusual you ate or drank in the day or two before, any changes in your environment or new products you were exposed to, and your stress levels in the 48 to 72 hours leading up to it.

That last point is worth repeating: look back 48 to 72 hours before a flare appeared, not just the day it started. Triggers often take a day or two to show up on your skin.

A Few Things to Keep in Mind

Tracking takes patience. Skin changes don’t happen overnight — it can take 4 to 6 weeks of consistency before clear patterns emerge. Be patient with yourself and the process. A few more things that can help:

• Watch for hidden irritants — Check your laundry detergent, soaps, and any new medications. Rough fabrics like wool, synthetic blends, and added fragrances are common culprits that are easy to miss.
• Test one thing at a time — If you think diet might be a factor, eliminate one food group at a time. Cutting out multiple things at once makes it impossible to know which one made a difference.
• Consider allergy testing — If you suspect allergies are contributing to your flares, ask your care team about patch testing. It can help rule out contact reactions as an underlying trigger.
• Don’t forget medications — Some medications can aggravate skin conditions. Always share your full list of prescriptions and supplements with your care team so they have the complete picture.
• Physical trauma counts — Scratching, scrubbing, bug bites, and small cuts can all trigger new flares — sometimes 10 to 20 days later. Gentle handling of your skin every single day matters more than you might think.
