# Pores

What the Pores parameter counts, the facial zones and size categories it reports on, and how to read its scores and grades.

## About Parameter

The parameter detects and counts visible facial pores—the surface openings of sebaceous glands. Pore visibility is influenced by sebum output, skin texture, age, and genetics, and changes in pore appearance are a common way to track skin-quality progress over time.

## Features

1. Per-zone analysis across nose, forehead, left cheek, and right cheek.
2. Pores are reported in two size categories: all visible pores, and enlarged pores.
3. Eye and mouth (perioral) regions are excluded to avoid mistaking eyelashes, fine lines, and lip texture for pores.
4. Works with a single front image or a 3-side triplet (front, left, right).

## Output

1. Score from 1 to 100 for overall pore appearance. The score penalises enlarged pores much more heavily than small ones, so it primarily reflects enlarged-pore burden.
2. Grade from 1 to 5 (discretized score band).
3. Algorithm-assigned skin condition tag (Great, Good, Average, Poor).
4. Number of all visible pores, for the whole face and broken down by zone (nose, forehead, left cheek, right cheek).
5. Number of enlarged pores, with the same per-zone breakdown.
6. Vector masks for detected pores and for enlarged pores, returned per available side (front, left, right).

{% hint style="info" %}
Please note that the pores mask, score, and grade are all calculated based on pore count and pore size distribution across both size categories (all visible pores and enlarged pores). If you want a mask breakdown by size category, you may be interested in the [Related Advanced Parameters](#related-advanced-parameters) section below.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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/face-skin-analysis-3-0/pores.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.
