Why finding yours matters
Repeated, uncontrolled flares are not just bad days. They are the years that build the visible vessels and fixed redness that do not fade once the flare ends. Knowing your triggers is how you stop adding to that pile.
The free ikrein guide
How to find your rosacea triggers. And what to do about each.
Triggers is one of the most overused words in rosacea care, and one of the least explained. The wine that did nothing in June can wreck your week in October. The free guide explains why, walks you through finding yours, and tells you what to do for each. Sent to your inbox.

What's inside
Six things this guide does that most articles do not.
Not "drink less wine, wear sunscreen." Specifics. Why each trigger does what it does, how to figure out which ones are yours, what to do for each, and the skincare ingredients that quietly sabotage rosacea-prone skin even when the label says gentle.
02
The eight most common triggers
Ranked by what shows up across patient surveys: sun, stress, heat, alcohol, spicy food, exercise, weather, skincare. Plus the dietary ones (cinnamaldehyde, histamine) that show up later for some people.
03
The biology that makes them triggers
Hyperreactive blood vessels, cathelicidin LL-37, TRP channels, and a barrier that has been worn down by ordinary cleansing. Plain explanations, not jargon.
04
A 2 to 4 week method to find yours
What to track, how to read the data, and what patterns to look for. Not a diary forever. A focused method that tells you what you actually need to know.
05
What to do for each trigger
Per trigger: the practical action and the why. Sun, heat, alcohol, spicy food, stress, exercise, cold and wind, and a dedicated section on skincare ingredients (including the high-percentage niacinamide problem most articles miss).
06
When prescription treatment is the next step
The topicals dermatologists actually prescribe (azelaic acid, metronidazole, ivermectin, brimonidine, oxymetazoline) and the low-dose oral. What each one does, and when it is the right call.
Why it matters
Triggers are not just today's flare.
Repeated, uncontrolled flares are not just bad days. They are the years that build the visible vessels and fixed redness that do not fade once the flare ends. The longer you go without identifying what is setting your skin off, the more the inflammation gets to compound, and the more of it leaves a mark.
That is why dermatology guidelines list trigger avoidance as first-line, alongside topical and oral treatments. It is also why the guide does the work most generic advice skips: explaining why each trigger does what it does, how to find the ones that are yours specifically, and what to do for each.
Who it's for
For the people who have tried everything else.
If you have lived with rosacea for a while, you have probably been told to just avoid your triggers by people who never told you what yours are, how to find them, or why it matters. You have a drawer of sensitive-skin lines that worked for a week. You wear the hat. You order the iced tea. And your face is still flaring. This guide is for you.
ikrein is a telehealth practice built around one thing: rosacea. The guide is from the same team. A board-certified dermatologist reviews each person's photos and history and prescribes a custom formula drawing from the actives with the strongest evidence in rosacea. If the guide makes the case for trying that, the door is open.
