Rules can change, so Rankhog keeps verification dates and the original public Reddit sources visible.

Rule summary

  • 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.
  • 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.
  • 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.
  • 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
  • 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
  • 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.

Works well

  • Share a personal story about a specific trigger or flare and what helped you, without telling others they must try the same thing.
  • Post a question about coping methods for eczema-related social anxiety, framed as your own experience.
  • Cite an academic journal or an article written by a PhD researcher when discussing broader claims about treatments or side effects.
  • Reply with empathy and nuance when someone shares an uncomfortable side effect, avoiding wide, sweeping generalizations.

Avoid

  • No affiliate marketing, no pharmaceutical marketing, no supplements or stem cell marketing, no influencer promotion, no MLM, and no for-profit pharma sponsored forums.
  • Do not post gofundme campaigns for individuals.
  • Do not offer diagnoses or emergency help, and do not treat the subreddit as a substitute for professional medical advice.
  • Do not make broad statements like everyone must try a product, and do not cite non-academic sources for broader claims.
  • Do not discuss COVID vaccines or topics outside eczema, atopic dermatitis, and contact dermatitis.
  • Do not make wide, sweeping generalizations or calls for censorship when someone shares an uncomfortable anecdote about side effects.

What r/eczema Is For

This community is a place for people with eczema to talk with others about their experiences, treatments, coping methods, and life with 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. The community expects kindness, consideration, and compassion, because eczema is frequently accompanied by physical pain and social anxiety.

Rules That Matter Before Posting

The rule No marketing is the one that decides whether a marketing-adjacent post survives, because it bans affiliate marketing, pharmaceutical marketing, supplements and stem cell marketing, influencers, MLM, for-profit pharma sponsored forums, and gofundme campaigns for individuals. The rule Anecdotes do not equal evidence also matters, because it lets you talk about what worked for you and you alone, while broader statements require credible sources such as academic journals and articles written by PhD researchers. The rule Only medical professionals can provide diagnosis and emergency help keeps you from offering diagnoses or medical advice. The rule Stay on the topic of eczema keeps posts focused on eczema, atopic dermatitis, and contact dermatitis, and says the subreddit is not a place for discussions about COVID vaccines. The rule Drug adverse effects and side effects asks for nuance and openness when discussing side effects and adverse effects.

What To Post

A good post here is a personal story about your own experience with eczema, what worked for you and you alone, and how you cope. If you want to make a broader claim, back it with credible sources such as academic journals and articles written by PhD researchers. Keep your tone kind and compassionate, and stay strictly on the topic of eczema and related skin conditions. A founder doing respectful Reddit marketing would share honestly, cite academic sources where needed, and never promote a product or link.

What To Avoid

Avoid any form of marketing, including affiliate marketing, pharmaceutical marketing, supplements and stem cell marketing, Instagram, YouTube, and TikTok influencers, MLM, for-profit pharma sponsored forums, and gofundme campaigns for individuals. Do not offer diagnoses or emergency help, and do not treat the subreddit as a substitute for professional medical advice. Do not make broad statements about what everyone must try, and do not cite non-academic sources for broader claims. Do not discuss COVID vaccines or topics outside eczema, atopic dermatitis, and contact dermatitis. Do not make wide, sweeping generalizations or calls for censorship when someone shares an uncomfortable anecdote about side effects.
