# Acne Pro

What the Acne Pro application detects, the acne types it distinguishes, and the limits of the results it returns.

{% hint style="warning" %}
Our Application can identify different types of acne based on image analysis; however, acne is a medical condition that varies in severity and requires professional evaluation. This analysis is not a substitute for a diagnosis by a qualified healthcare provider. Before starting any treatment, consult a dermatologist or medical professional to determine the most suitable approach for your skin health.

## About Application

1. This Application estimates the presence and severity of visible acne, differentiating between four types: papules, pustules, inflammation, and post-acne hyperpigmentation.
2. It analyzes skin health parameters in the following areas: forehead, right/left cheeks, nose and chin areas.
3. The Application provides the following metrics:
   1. Acne class - overall acne class that might be one of None, Post-acne, Spot, Mild, Moderate and Severe.

      * **None:** No visible signs of acne.
      * **Post-acne:** Indicates the presence of lingering effects from previous acne, such as hyperpigmentation or scarring, but no active acne lesions.
      * **Spot:** Occasional, isolated acne lesions.
      * **Mild:** A small number of non-inflammatory lesions (e.g., comedones) and possibly a few inflammatory lesions (e.g., papules, pustules).
      * **Moderate:** A greater number of both non-inflammatory and inflammatory lesions, potentially affecting a larger area of the skin.
      * **Severe:** Extensive inflammatory lesions, often with nodules or cysts, that may be painful and have a higher risk of scarring.

   2. Amount of pustules.
      1. Pustules are severe acne pimples that originate from papules. It is a painful skin condition usually consisting of necrotic inflammatory cells. Pustules' main characteristics are the red color of the pimple (that is a sigh of inflammatory processes persisting there) and the presence of pustules.
   3. Amount of papules.
      1. Papules are one of the most common acne manifestations. This is the type of pimples that occurs when dead skin cells and oil from the skin clog hair follicles. Typically, papules are small, well defined bumps on the skin with little to no inflammation.
   4. Density of inflammation measured in per mile of total skin area.
      1. Inflammation is a complex and universal reaction of the human body. It could be characterized by local redness, pain, heat and swelling. Acne inflammation is induced by uncontrolled P. acne bacteria overgrowth. Chronic inflammation often accompanies severe acne and can involve a wide range of skin cells.
   5. Density of Post-acne Hyperpigmentation measured in per mile of total skin area.
      1. Post-acne Hyperpigmentation (HP) is the skin's reaction to severe or intermediate inflammation. It can affect the secretion of melanin by the pigmented cells (melanocytes) or even increase the number of such cells in the affected areas making the skin look darker. Hyperpigmentation occurs in the areas that are affected the most by pustules and inflammation. The shape of HP matches the areas of severe inflammation and can vary in size.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.saas.haut.ai/haut.ai/haut.ai-features/algorithms/acne-pro.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
