# Dark Circles

What the Dark Circles parameter detects under the eyes, and how to read the scores, grades, and condition tags it returns.

## About Parameter

The parameter detects and analyzes dark circles under the eyes—commonly caused by pigmentation, thin skin, poor circulation, or fatigue. These shadows can contribute to a tired or aged appearance and are a key concern in both cosmetic and dermatological evaluations.

## Features

1. Works with 1 and 3 side facial images.

## Output

1. Score from 1 to 100.
2. Grade from 1 to 5.
3. Algorithm-assigned skin condition tag (Great, Good, Average, Poor).
4. The density (area) of dark circles under the left and right eyes, shown separately in the SaaS results view.
5. Vector mask for detected features.

# 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/dark-circles.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.
