Nahatüüp

Nahatüüp is an Estonian term for skin type, a classification used in dermatology and cosmetology to describe the general characteristics and behavior of an individual's skin. Common categories include normal, dry, oily, combination and sensitive skin, each defined by differences in sebum production, moisture retention, texture and reactivity.

Assessment of nahatüüp can be done by visual inspection, questionnaire, simple blotting tests or instrumentally with tools measuring transepidermal water loss and sebum production. Dermatologists also consider medical history, symptoms and environmental exposures when determining type. Skin type may change across the life course under the influence of genetics, age, hormones, climate, diet, medication and skincare routines.

Knowing one’s nahatüüp helps guide appropriate skin care choices and management of conditions such as acne, atopic dermatitis and rosacea. For example, dry skin benefits from emollients and barrier-repairing formulations, while oily skin often responds to non-comedogenic, oil-regulating products. Sensitive skin typically requires gentle, fragrance-free products and patch testing.

While skin type is a useful practical framework, clinicians emphasize that temporary states (e.g., dehydration, irritation) can mimic different types and that personalised assessment is important for persistent problems. Research continues into the biological mechanisms underlying skin variation and into products tailored to specific nahatüüp profiles.
