Skin metrics

Skin metrics describe your skin’s visual features, such as redness, pigmentation and the presence of dark circles. Please be aware that these skin metrics are provided only for the purpose of demonstrating computer vision and machine learning algorithms.

Our skin metrics are not intended to be a substitute for professional medical advice, diagnosis or treatment. Always seek the advice of your physician or other qualified healthcare provider on any medical condition or treatment and before undertaking a new healthcare regimen.




Our skin has a natural pink color because of our blood vessels. Increased skin redness can be associated with allergic reactions and inflammatory processes. The most common environmental factors leading to facial redness are cold air or ultraviolet radiation.

A higher parameter value is associated with low redness levels.


The uniformness metric shows how smooth and even your skin is. It takes into account eruptions, age spots, freckles, and blood vessels close to the surface, along with texture-associated skin features.

The higher the value of this parameter, the more uniform and smooth your skin.


Pigmentation refers to the coloring of the skin and is determined mainly by the brown pigment melanin. Pigmentation takes into account how prominent any dark spots, moles or freckles are. Hyperpigmentation is usually harmless but can sometimes be caused by an underlying medical condition. In instances of low parameter values, it is recommended to consult a specialist.

Skin tone

Skin tone indicates how tanned your skin is. Many pigments affect the color of the skin. One of the most important factors affecting skin tone is the quantity of melanin the skin contains. The amount of melanin in the skin is determined by genetic factors, but it is also increased by the impact of the sun’s radiation. The ITA° system was developed to determine the overall pigmentation or skin color. The lighter the skin, the higher the ITA°. ITA values are associated with six classes of skin tanning: very light, light, intermediate, tan, brown and dark.


Lines, also known as wrinkles, appear as a sign of the aging process. As we age and are exposed to adverse environmental factors, the collagen and hyaluronic acid content of our skin decreases, causing the loss of moisture and elasticity. These changes lead to the development of wrinkles and sagging, or downward shifts of the skin causing nasolabial folds, marionette folds, and jowls. Over time, our lines become more prominent, developing from fine lines into deep lines. The higher the value of this parameter, the less prominent lines you have.

Wrinkles (Deprecated)

Wrinkles are a sign of the aging process. As we age and are exposed to adverse environmental factors, the level of collagen and hyaluronic acid in the skin decreases and it loses its elasticity and moisture. These changes lead to the development of wrinkles and their higher prominence over time.

The lower the parameter value, the more wrinkles you have.

Perceived age

Age can convey important social meanings to yourself and others. Perceived age reflects how old you look based on the overall appearance of your face and your skin’s condition.

Eye age

This metric is predicted based on the part of the face that is most prone to the aging process: the areas around the eyes. Eye age reflects the pace of aging.


Acne is a skin disorder that has many variances in its appearance between genders. The pathogenesis of acne is multifactorial and it involves four main pathways: excess sebum production, comedogenesis, Propionibacterium acnes and complex inflammatory mechanisms involving both innate and acquired immunity. Acne areas are detected and the ratio of skin area covered by detected acne is calculated. Also, for each acne spot, the local irritation is estimated.

A high parameter value is associated with low acne levels.


Skin usually has pores in different conditions. They contain the tiny ostia from either pilosebaceous follicles (with sebaceous glands) or sweat glands, which greatly affect their condition. Enlarged, filamented or blackheaded pores require care.

A high pores parameter value is associated with pores in good condition.

Dark circles

Dark circles, also known as periorbital hyperpigmentation, can give a fatigued and less youthful appearance to the face. The etiology of under-eye circles is multifactorial and includes periorbital volume loss and skin laxity, orbital fat prolapse, increased prominence and density of subcutaneous vasculature, and excessive pigmentation.

The lower the value of this parameter, the more prominent dark circles you have.

Lacrimal groove

Lacrimal grooves are a deformity of the orbital fat that are noticeable as a result of variable anatomical differences among the human population, eyelid sagging, and aging. In instances of anatomical variability, a rejuvenation of this area is challenging.

The lower the value of this parameter, the more prominent your lacrimal grooves.

Eye bags

Eye bags are formed because of the loss of skin elasticity in the lower eyelid. The development of eye bags is associated with the aging process, but it can also be a sign of a lack of sleep or stagnation of blood in vessels under the skin in the case of circulatory disorders.

The lower the value of this parameter, the more prominent your eye bags.

Sagging (Deprecated)

“Smile lines”, or nasolabial folds, are a common facial feature. These folds run from each side of the nose to the corners of the mouth. The forming of the nasolabial fold is associated with the structure of the human face, sagging of midface soft tissue, and a prominent decline in the tone of the facial muscles, which are all caused by aging.

The lower the value of this parameter, the more prominent the nasolabial folds.


Translucency is a parameter based on human perception of skin luminosity. The physical foundation of skin luminosity is light reflection. The uniformness and intensity of this light reflection can be affected by a combination of low skin tightness, non-uniform pigmentation, oiliness, and the skin’s hydration level. With respect to all of these parameters, healthy skin manifests as a normal, smooth distribution of reflected light, which is perceptually interpreted as good skin translucency.


The hydration parameter reflects how skin suffers from a lack of water. Problems with hydration can be identified through indirect skin features, such as fine lines or cracks, irritation, flaking, scaling, or peeling.

High parameter values are associated with good hydration levels.

Facial landmarks

Facial landmarks are a set of face points that allow the marking of facial features, such as the nose, mouth, eyes, etc. Haut.AI provides 53 predefined landmark points.

Hair metrics




The frizziness metric combines split ends and frizz. It can lead to the hair’s texture becoming irregular and frizzy. Split ends happen when the ends of your hair become dry, brittle and frayed. Frizz is hair that does not align with the surrounding hairs but stands up or curls independently, creating a fuzzy or irregular texture. The three main causes of frizz are genetics, hair damage and humidity. The higher the parameter value, the smoother your hair.

Hair Color

This metric describes the hair’s color. All natural hair colors are the result of two pigments: eumelanin and pheomelanin. Generally, if more melanin is present, the color of the hair is darker; if less melanin is present, the hair color is lighter.

Hair Color Uniformness

This metric shows how uniform your hair color is. A higher uniformness level is associated with a higher value for this parameter.

Hair Length

This metric calculates the length of your hair.

Hair Volume

Hair volume is often associated with overall health. However, it is determined by many factors, such as hair type, heredity, hair thickness and hair density. The color also influences the volume: blond hair is often thin and soft, while dark hair is usually thicker. The reasons for a loss of visual volume in a hairstyle can be hair loss or hair thinning due to a lack of vitamins or diseases. The higher the parameter value, the more volume your hair has.

Hair Curliness

Hair type and texture are determined by genetics and environment. Hair texture can change with age. The oil glands in the scalp also shrink with age. How you treat and style your hair can change its texture. The most common hair type across the world is straight hair.

Hair Damage Score

This metric shows the aggregated score for hair damage, which can be the result of a variety of factors, including specific hair products and procedures, diet, stress, or improper hair care. The higher the value of this parameter, the healthier your hair.
