About r/eczema
A source-backed Rankhog guide to r/eczema: public rules, community context, posting fit, and startup-promotion risk before you publish.Checked from the r/eczema rules on Reddit.
r/eczema rules
6 rules, in the community's own words.
- 1
Only medical professionals can provide diagnosis and emergency help
Contact a medical professional if you are having a medical emergency or require differential diagnosis. /r/eczema is not a substitute for professional medical advice.
- 2
Anecdotes do not equal evidence
Each person's causes and triggers differ. What worked for you might not work for someone else. Instead of making a broad statements (e.g. everyone must try XXX product), you may talk about what has worked for you and you alone. Broader statements require credible sources such as academic journals and articles written by PhD researchers.
- 3
This community has high standards for empathy
Eczema is frequently accompanied by physical pain and social anxiety. Kindness, consideration, and compassion are encouraged when replying to posts.
- 4
Stay on the topic of eczema
Posts and comments are limited to the biological, psychological, and social issues regarding the specific inflammatory skin conditions called eczema, atopic dermatitis, and contact dermatitis. Furthermore, /r/eczema is not a place for discussions about COVID vaccines. Other subreddits you might consider consulting include: /r/SebDerm /r/EczeMEMEs /r/TS_Withdrawal /r/EczemaUK /r/EczeMABs
- 5
No marketing
- No affiliate marketing
- No pharmaceutical marketing
- No supplements/stem cell marketing
- No Instagram/YouTube/TikTok influencers
- No pharma sponsored industry events (NEA)
- No multi-level marketing (MLM)
- No for-profit pharma sponsored forums (PatientsLikeMe, Inspire, Health Union)
- No gofundme campaigns for individuals
- 6
Drug adverse effects & side effects
Several atopic dermatitis treatments have known adverse effects and side effects in 5-15% of the patient population and are still considered generally safe for use. Please use nuance and openness when discussing side effects and adverse effects. Please avoid wide, sweeping generalizations and calls for censorship when someone expresses an anecdote or claim that you find uncomfortable. The enemies are not the doctors, companies and other patients. Our adversary is an overactive Th2 response.
What to post in r/eczema
What fits the room, and what gets removed.
Works well
- A plain first person post about your own eczema journey, framed strictly as what happened to you and what you tried.
- A question asking how other members cope with a specific everyday challenge of living with eczema, like sleep, work, or social situations.
- A comment that answers someone's post with your own single experience plus a kind word, with no links and no recommendations for everyone.
- A post about the psychological or social side of eczema, which the rules explicitly welcome as on topic.
- A careful discussion of a treatment's side effects that uses nuance and openness instead of sweeping generalizations, as rule 6 asks.
- A summary of a credible academic source that supports a broader point, cited properly under “Anecdotes do not equal evidence”.
Avoid
- Posting any kind of promotion, because “No marketing” bans affiliate links, pharmaceutical marketing, supplements, stem cell pitches, influencers, MLM, pharma sponsored forums, and gofundme campaigns.
- Telling people what they must try, because “Anecdotes do not equal evidence” removes broad statements made without credible sources.
- Suggesting what someone's condition might be, because “Only medical professionals can provide diagnosis and emergency help” forbids diagnosis in the community.
- Going off topic or mentioning COVID vaccines, because “Stay on the topic of eczema” limits posts to eczema, atopic dermatitis, and contact dermatitis.
- Being harsh or dismissive in replies, because “This community has high standards for empathy” expects kindness and compassion.
- Making sweeping generalizations about treatment side effects or attacking doctors, companies, or other patients, which rule 6 asks people to avoid.
Best hours to post in r/eczema
No pattern yet. r/eczema does not have enough top posts from the last 90 days to name its best hours.
What r/eczema Is For
This is a support community for people living with eczema. The description says people come here to talk with others about their experiences, treatments, coping methods, and life with eczema. The rules frame it around the biological, psychological, and social sides of eczema, atopic dermatitis, and contact dermatitis. So the room is patients and caregivers swapping lived experience, not shoppers hunting for products. The rules also point people with related conditions to other subreddits like r/SebDerm, r/EczeMEMEs, r/TS_Withdrawal, r/EczemaUK, and r/EczeMABs, which tells you the moderators care about keeping this space tightly focused.
Rules That Matter Before Posting
The rule that decides everything for a founder is “No marketing”, which bans affiliate marketing, pharmaceutical marketing, supplement and stem cell marketing, influencers, MLM, pharma sponsored forums, and gofundme campaigns. That is about as wide a promotion ban as you will see, so any post that reads like a pitch is gone. “Anecdotes do not equal evidence” matters next, because you can share what worked for you and you alone, but broad claims need credible sources like academic journals. “Only medical professionals can provide diagnosis and emergency help” means you never diagnose anyone or position your product as a treatment answer. “This community has high standards for empathy” sets the tone for every reply you write. “Stay on the topic of eczema” keeps posts on eczema, atopic dermatitis, and contact dermatitis, and it explicitly rules out COVID vaccine discussions.
What To Post
The only safe play here is to show up as a person, not a brand. If you have a genuine personal or family connection to eczema, share your own story in your own words and keep it framed as your experience, never as advice for everyone. Ask sincere questions about what living with eczema is like, what flares feel like, or how people cope day to day, since the description says coping methods and life with eczema are core topics. If you built something in this space, you can talk about the problem you saw, but do not pitch, link, or hint at a product, because “No marketing” removes all of that. Answer other people with kindness and add your single data point, and back any broader claim with credible academic sources if you must make one.
What To Avoid
Do not market anything, because “No marketing” covers affiliate links, pharma, supplements, stem cells, influencers, MLM, sponsored forums, and fundraising. Do not make broad claims like everyone must try a product, because “Anecdotes do not equal evidence” requires credible sources for statements that go beyond your own case. Do not diagnose anyone or handle emergencies, because “Only medical professionals can provide diagnosis and emergency help” says this subreddit is not a substitute for professional medical advice. Do not drift off topic or bring up COVID vaccines, because “Stay on the topic of eczema” limits the discussion to eczema, atopic dermatitis, and contact dermatitis. Do not be cold or dismissive in comments, because “This community has high standards for empathy” expects kindness toward people in pain. And per rule 6, avoid sweeping generalizations about side effects or calls to silence people whose stories make you uncomfortable.
A note from Anthony
The empathy rule here is not decoration, it is written as a standard, and that tells you exactly what kind of room this is. I also love the line that the adversary is an overactive Th2 response, not the doctors or the other patients, because it sets the tone for how disagreements should go. If you come here to sell anything, you will lose, so come to help first or do not come at all.

Can I discuss COVID vaccines here?
No. “Stay on the topic of eczema” says the community is not a place for discussions about COVID vaccines.
