Wrinkles

Wrinkles are lines and folds visible on the skin surface and may be influenced by facial movement, ultraviolet exposure, reduced hydration, and changes in skin elasticity. ChoiceDx AI Skin Analysis evaluates the pattern, distribution, and visible depth of lines around key areas such as the eyes, forehead, and glabella, supporting skin-aging consultations and personalized hydration and firmness recommendations.

Sebum

Sebum is a lipid-rich substance produced by sebaceous glands that helps protect the surface of the skin and hair. ChoiceDx AI Skin Analysis evaluates sebum accumulation around pores and regional secretion patterns, supporting consultations on excess or insufficient sebum and potential pore congestion, as well as recommendations for cleansing, oil-balance, and pore-care products.

Pores

Pores are small visible openings on the skin surface connected to hair follicles and sebaceous glands. Their appearance may be influenced by sebum production, reduced elasticity around the pore, follicle size, and skin texture. ChoiceDx AI Skin Analysis evaluates pore count, size, distribution, and concentrated areas to support pore-care consultations and related product recommendations.

Keratin

The stratum corneum consists of keratin-rich dead skin cells that form the skin’s outer protective barrier against external stress and water loss. ChoiceDx AI Skin Analysis evaluates surface roughness, flaking, and uneven reflection patterns to identify signs associated with excessive buildup or dryness and support gentle cleansing, hydration, and exfoliation consultations.

Spots & Blemishes

Spots and blemishes are localized brown or darker areas of uneven pigmentation that may be associated with ultraviolet exposure, skin aging, or post-inflammatory changes. ChoiceDx AI Skin Analysis evaluates visible spot areas based on color contrast and distribution patterns, supporting skin-tone consultations and recommendations for sun protection and brightening products.

Hyperpigmentation

Hyperpigmentation refers to areas that appear darker than the surrounding skin because of a relatively higher concentration or distribution of melanin. ChoiceDx AI Skin Analysis evaluates pigmentation intensity, area, and distribution in standard and specialized-light images, helping visualize uneven skin tone and support sun-care and personalized brightening consultations.

Dark Circles

Dark circles describe a darker appearance beneath the eyes and may be influenced by pigmentation, visible vascularity, skin thickness, and shadowing from the under-eye contour. ChoiceDx AI Skin Analysis evaluates color and brightness differences in the under-eye area to assess visible severity and left-right asymmetry, supporting consultations for hydration, tone, and firmness around the eyes.

Radiance

Skin radiance describes a clear, healthy-looking appearance created when light reflects evenly from the skin surface. It is influenced by hydration, texture, tone evenness, and surface smoothness. ChoiceDx AI Skin Analysis evaluates facial brightness and reflection uniformity to visualize radiance and support hydration, texture, and tone-care consultations.

Redness & Sensitivity

Skin redness is a visible red appearance that may occur with increased blood flow or skin irritation, while sensitivity describes a tendency to react readily to external stimuli. ChoiceDx AI Skin Analysis evaluates the distribution and intensity of red tones across facial areas to visualize redness patterns and potentially sensitive zones, supporting gentle, soothing, and barrier-care consultations.

Skin Tone

Skin tone is the overall color appearance of the skin created by the combined effects of melanin, blood flow, skin thickness, and light reflection. ChoiceDx AI Skin Analysis evaluates brightness and color distribution across facial areas in standardized images to assess tone and evenness, supporting complexion consultations and base-makeup shade recommendations.

Skin Texture

Skin texture refers to surface smoothness and fine irregularities created by microrelief, dryness lines, pores, and the condition of the stratum corneum. ChoiceDx AI Skin Analysis evaluates fine surface patterns and contrast variations to identify rough or uneven areas and support consultations for hydration, exfoliation, pore care, and firmness.

Discoloration

Skin discoloration refers to localized areas whose color differs from the surrounding skin and may be associated with increased pigment, post-inflammatory changes, or external irritation. ChoiceDx AI Skin Analysis evaluates regional color differences and boundaries to visualize the location and distribution of discoloration, supporting skin-tone and sun-protection consultations.

Skin Elasticity

Skin elasticity describes the skin’s ability to return toward its original form after deformation, while firmness refers to how supported and taut the skin appears. ChoiceDx AI Skin Analysis evaluates image features associated with facial contours, visible sagging, and surface patterns to support consultations and personalized recommendations for wrinkles, firmness, and hydration.

Scalp Moisture

Scalp moisture refers to the water-holding condition of the scalp’s stratum corneum and is an important factor in maintaining the scalp barrier and a comfortable scalp environment. Low moisture may be associated with dryness, tightness, visible flaking, and discomfort. ChoiceDx AI Scalp Analysis evaluates moisture balance and regional dryness patterns using scalp images and measurement data, supporting hydration-focused consultations and personalized hair-care recommendations.

Scalp Oiliness

Scalp oiliness refers to the level of visible oil and shine on the scalp surface and around the hair roots. Excess oil may make hair appear greasy or weighed down, while insufficient surface oil may be associated with a dry or rough scalp. ChoiceDx AI Scalp Analysis evaluates reflected light and scalp-surface patterns to identify oil distribution and shine tendencies, supporting consultations for dry, combination, and oily scalps as well as cleansing routines and product recommendations.

Scalp Sebum

Scalp sebum is a lipid-rich substance produced by sebaceous glands connected to hair follicles, helping protect and lubricate the scalp and hair surface. Excessive accumulation may combine with debris and flakes around follicles and alter the scalp environment. ChoiceDx AI Scalp Analysis evaluates sebum-accumulation patterns around follicles and hair roots to identify excess, insufficiency, and regional differences, supporting oil-balance, cleansing, and scalp-care consultations.

Scalp Flakes

Scalp flakes consist of shed or accumulated corneocytes from the outermost layer of the scalp. Fine shedding may occur during normal skin renewal, while dryness, sebum imbalance, or irritation may result in more visible flakes or dandruff. ChoiceDx AI Scalp Analysis evaluates flake size, color, distribution, and concentrated areas to identify dry- or oily-flaking tendencies and support gentle cleansing, hydration, and scalp-exfoliation consultations.

Hair Density

Hair density refers to the number and distribution of visible hairs or follicular units within a defined scalp area. Density may vary by scalp region, hair thickness, growth cycle, and imaging conditions. ChoiceDx AI Hair Analysis evaluates visible hair count, distribution, scalp exposure, and concentration patterns within the captured area to visualize regional density differences and support ongoing hair and scalp monitoring and professional consultations.

Scalp Sensitivity

Scalp sensitivity describes a tendency for the scalp to react readily to external stimuli or environmental changes and may be associated with redness, itching, stinging, warmth, or discomfort. ChoiceDx AI Scalp Analysis evaluates visible red-tone signals, regional color differences, and surface patterns to visualize areas showing sensitivity-related characteristics and support gentle, soothing, and scalp-barrier-care consultations.

Hair-Loss-Related Characteristics

Hair loss broadly refers to visible reductions in hair count or increased scalp exposure caused by changes in the hair growth cycle or follicle condition. ChoiceDx AI hair analysis evaluates visible hair-loss-related characteristics within the captured area, including hair density, scalp exposure, variations in apparent hair thickness, and distribution patterns. It supports comparison by area, ongoing records, and professional consultations. The results do not replace a medical diagnosis of a hair-loss condition.

Overall Scalp Condition

Overall scalp condition represents a combined view of moisture, oiliness, sebum, flakes, visible redness, hair density, and the scalp-surface environment. Rather than interpreting a single metric in isolation, it is important to review the balance among multiple indicators and regional differences. ChoiceDx AI Scalp Analysis integrates hair and scalp analysis results into a unified report, helping users understand their current condition and supporting consultations, history management, and personalized scalp and hair-care recommendations.

ChoiceDx analysis results may vary depending on imaging conditions, current skin condition, the device used, and the software version. The results are intended to provide skin-condition information and support consultations and do not replace medical diagnosis or treatment decisions.
