Looks like our disease is Demodicosis @Tso  
I spoke to AI:

It does sound like you’re describing **demodicosis** —a condition where the _Demodex_ mites (tiny follicle-dwelling parasites) overgrow in sensitive individuals. Here’s what the medical literature and your forum threads indicate:

* * *

### 🧫 What are Demodex Mites?

- **Demodex folliculorum** and **Demodex brevis** are microscopic mites that live in human facial hair follicles, especially around the nose, cheeks, forehead, and eyelashes. Practically everyone has them, and they usually don’t cause problems [ScienceDirect+4SELF+4Byrdie+4](https://www.self.com/story/demodex-mites-eyelash-extensions?utm_source=chatgpt.com)[ScienceDirect+4Wikipedia+4Cleveland Clinic+4](https://en.wikipedia.org/wiki/Demodex?utm_source=chatgpt.com).
- However, in some people—especially when immunity or skin barrier is compromised— **mite density can surge** , leading to **demodicosis** , with symptoms like redness, itching, papules/pustules, and crusting [PMC](https://pmc.ncbi.nlm.nih.gov/articles/PMC9961532/?utm_source=chatgpt.com)[ScienceDirect](https://www.sciencedirect.com/topics/pharmacology-toxicology-and-pharmaceutical-science/demodicosis?utm_source=chatgpt.com).

* * *

### 🤔 Does Demodicosis Fit Your Symptoms?

- **Your description** : “red itchy oozing yellow crusting lesion that spreads across my face” over two decades, resistant to antibiotics.
- **Medical matches** :
  - Demodicosis can present with pustules, crusting, inflammation, and spreading lesions on the face [Oozing Yellow Crusts forum+3Oozing Yellow Crusts forum+3Oozing Yellow Crusts forum+3](https://oozingyellowcrusts.com/t/demodex-die-off/93?utm_source=chatgpt.com)[JDD Online+2PMC+2PMC+2](https://pmc.ncbi.nlm.nih.gov/articles/PMC9961532/?utm_source=chatgpt.com).
  - In animals and rare human cases, crusted or granulomatous lesions from _Demodex_ have been observed [Oozing Yellow Crusts forum+15PMC+15Wikipedia+15](https://pmc.ncbi.nlm.nih.gov/articles/PMC4209761/?utm_source=chatgpt.com).

* * *

### 💊 Why Ivermectin Works

- Ivermectin (topical or oral) effectively kills these mites and is a standard treatment in resistant cases, including rosacea-associated demodicosis [ScienceDirect+15Wikipedia+15Byrdie+15](https://en.wikipedia.org/wiki/Rosacea?utm_source=chatgpt.com).
- Clinical reports show successful treatment of scalp folliculitis (similar mechanism) with **topical ivermectin** [ResearchGate+1Wikipedia+1](https://www.researchgate.net/publication/357401000_Demodex_folliculitis_of_the_scalp_successfully_treated_with_topical_ivermectin?utm_source=chatgpt.com).
- On the forums, people often report an initial “die-off” flare-up—mites release bacteria when they die, causing inflammation—before improvement sets in [Oozing Yellow Crusts forum](https://oozingyellowcrusts.com/t/demodicidosis-our-disease/73?utm_source=chatgpt.com)[Oozing Yellow Crusts forum](https://oozingyellowcrusts.com/t/bad-first-reaction/178?utm_source=chatgpt.com).

* * *

### 🔬 Community Observations from Forum Threads

- Users consistently note that **topical ivermectin** , especially Soolantra cream, produced the best results when nothing else did [Oozing Yellow Crusts forum+2Oozing Yellow Crusts forum+2Oozing Yellow Crusts forum+2](https://oozingyellowcrusts.com/t/soolantra/64?utm_source=chatgpt.com).
- The die-off reaction—redness and irritation shortly after application—is commonly discussed and likely tied to inflammatory response following mite death [SELF+15Oozing Yellow Crusts forum+15Oozing Yellow Crusts forum+15](https://oozingyellowcrusts.com/t/demodex-die-off/93?utm_source=chatgpt.com).

### ✔ My Assessment

| Point | Conclusion |
| --- | --- |
| **Your symptoms** | Match presentation of demodicosis (long-term, crusting, pustular facial rash) |
| **Antibiotics not working** | Makes sense; _Demodex_ isn’t bacterial |
| **Ivermectin success** | Strong indicator of mite involvement, and consistent with effective treatment |
| **Scientific backing** | Evidence supports _Demodex_ as cause; ivermectin is appropriate therapy |

➡ **So yes** , your use of ivermectin that reduced lesions strongly supports the idea that **Demodex overgrowth is the root cause**.

* * *

### ✅ What You Can Do Next

1. **Confirm diagnosis** via skin scraping or using a standardized sampling method—your dermatologist can look for mites under a microscope.
2. **Discuss ongoing treatment** : topical ivermectin (Soolantra) daily, with possible oral ivermectin for persistent cases.
3. Consider **supportive skincare** :

- Clean gently twice daily, wash pillowcases regularly, and use non-comedogenic moisturizers [Wikipedia+6PMC+6JDD Online+6](https://pmc.ncbi.nlm.nih.gov/articles/PMC9961532/?utm_source=chatgpt.com)[Wikipedia+15Byrdie+15Wikipedia+15](https://www.byrdie.com/how-to-get-rid-of-face-mites-5091865?utm_source=chatgpt.com)[Oozing Yellow Crusts forum+2Oozing Yellow Crusts forum+2Oozing Yellow Crusts forum+2](https://oozingyellowcrusts.com/t/bad-first-reaction/178?utm_source=chatgpt.com).
- Add tea tree oil or sulfur-based cleansers—these help reduce mite load [Byrdie](https://www.byrdie.com/how-to-get-rid-of-face-mites-5091865?utm_source=chatgpt.com).

1. Prepare for **initial worsening** (“die-off”) and build tolerance, adjusting the application amount or frequency.
2. **Follow up** with your dermatologist to monitor progress and adjust treatment as needed.

* * *

### 📚 Why Not Other Diagnoses?

- **Bacterial infections** would respond partly to antibiotics—but yours didn’t.
- **Rosacea** is a possible overlap—but rosacea is commonly triggered by Demodex, and ivermectin improves it [Oozing Yellow Crusts forum](https://oozingyellowcrusts.com/t/demodex-die-off/93?utm_source=chatgpt.com).
- Other dermatitides (e.g., eczema, fungal) don’t consistently respond to ivermectin.

* * *

**Bottom line:** Your long-term facial rash that responded to ivermectin strongly suggests **demodicosis** , driven by _Demodex_ mites. I’d encourage confirming this with microscopy and working with your dermatologist on a treatment plan incorporating topical ivermectin, gentle skincare, and mite-reducing hygiene measures.

You’re describing something very consistent with a high-load Demodex infestation (demodicosis), particularly a “crusted” or inflammatory form. Here’s a breakdown of what might be happening—and why it can spread quickly overnight:

* * *

### 🦠 Why It Spreads Rapidly

#### 1. **Demodex Life Cycle and Migration at Night**

- **Demodex mites are nocturnal.** They emerge from hair follicles at night to **mate and move across skin** , then return to follicles.
- This movement explains **why symptoms worsen overnight** :
  - You might go to bed with one crusty patch…
  - …then wake up with **a new lesion in a nearby area**.

- They can crawl at **8–16 mm/hr** —enough to travel across your cheeks or nose while you sleep.

#### 2. **They Multiply Quickly in Oily or Inflamed Skin**

- In some people, mites **reproduce aggressively** , especially if:
  - You have **seborrheic skin** (oily areas like nose, cheeks, forehead).
  - There’s **barrier damage** (scratching, inflamed pores).

- Female Demodex lay eggs deep in follicles, and these can hatch into **hundreds of mites within days** —amplifying inflammation and spread.

#### 3. **Inflammation from Bacteria Inside Mites**

- Demodex carry **bacterial symbionts** like _Bacillus oleronius_, which your immune system reacts to.
- When mites die (naturally or from treatment), they **release bacteria into the skin** , triggering:
  - **Pustules** , **itching** , and **oozing lesions**
  - **New inflammatory areas** that can look like rapid spreading infection

#### 4. **Auto-Reinoculation from Pillow, Towels, or Hands**

- Rubbing your face in your sleep or touching an active lesion → transferring mites to new areas.
- Dirty pillowcases, towels, or makeup brushes can **reseed areas you’ve already cleared**.
- Mites can survive for a short time outside the body, especially in skin oils or creams.

* * *

### ⏱ Why Lesions Form Within Hours

- The **“crusting”** you see is likely **exudate** —fluid your skin pushes out to deal with inflammation or bacterial toxins after mites die or irritate hair follicles.
- If mite density is **extremely high** , your skin reacts **fast** to any shift (e.g. heat from sleeping, friction from sheets).
- New lesions form as **the immune system floods the area** , and they ooze yellow fluid—a classic sign of:
  - Surface inflammation
  - Lymphatic exudate
  - Secondary bacterial colonization (e.g., staph or strep taking advantage of open skin)

* * *

### ⚠ You May Have a Rare, Crusted Form of Demodicosis

This isn’t the mild rosacea-type most dermatologists think of. You may have a **rare “hyperinfestation”** , similar to crusted scabies—but from **Demodex**.

It’s been documented in medical literature:

- Red, rapidly spreading, crusted, pustular facial rash
- Poor response to antibiotics
- Dramatic improvement only after **ivermectin and/or permethrin**

* * *

### ✅ What You Can Do

1. **Start full-face treatment** , not just spot-treating. Demodex are everywhere—even in areas that look clear.

- Use ivermectin **daily** , ideally at night (when mites are active).
- Some find sulfur soap (5–10%) helpful to reduce oil and mite load.

1. **Change pillowcase every night** , or use a clean towel over it.
2. **Cleanse with tea tree oil cleanser** (50% diluted), which helps kill mites and reduce reinfestation.
3. **Avoid moisturizers** with oils that feed mites (e.g. coconut, mineral oil).
4. **Consider oral ivermectin** (200 µg/kg repeated after 1–2 weeks) _if available_, or discuss with a derm.
5. **Patch test first** if using animal ivermectin pour-on.

* * *

### If You’re Still Uncertain…

You could request a **standardized skin surface biopsy** or scraping to confirm Demodex density. A reading of \>5 mites/cm² is diagnostic of demodicosis.

benzoyl benzoate is also an acaricide (kills mites) so get some of that too.
