About this trial

The goal of this observational study is to compare objective parameters of skin barrier function between healthy adult women who regularly use UV lamps during nail treatments and women who do not use UV lamps.

The main questions it aims to answer are:

* Do women who regularly use UV lamps for nail treatments show differences in skin barrier function compared to women who do not use UV lamps? * Are transepidermal water loss, skin hydration, and erythema associated with regular exposure to UV lamps used for nail treatments? * Does the duration of UV lamp use influence skin barrier function parameters?

Researchers will compare women who regularly use UV lamps during nail treatments with women who have natural nails and do not regularly expose their hands to UV lamps.

Participants will:

* Attend a single study visit. * Complete a short questionnaire regarding nail care habits and duration of UV lamp use. * Undergo non-invasive measurements of skin barrier function on the hands, including transepidermal water loss, skin hydration, and erythema assessments.

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

Healthy adult women (≥18 years of age)

Willing and able to provide written informed consent

Willing to complete the study questionnaire

Disqualifiers

Active skin diseases (e.g., psoriasis, vitiligo, or other dermatological conditions)

Allergic contact dermatitis

Pregnancy or breastfeeding

Use of topical or systemic corticosteroids, immunosuppressive drugs, or antihistamines

Trial population

Healthy adult women recruited from the general population. Participants will be classified into two groups based on their self-reported use of UV nail lamps during nail treatments: regular users of UV nail lamps and women who do not regularly use UV nail lamps and have natural nails.

Trial outcomes

Primary outcomes

1

Change in Transepidermal Water Loss (TEWL)

Skin barrier function will be assessed by measuring transepidermal water loss using a Tewameter TM 300 probe. Values will be expressed in g/m²/h

Time frame
Single assessment during the study visit
2

Change in Skin Hydration

Hydration of the stratum corneum will be assessed using a Corneometer CM 825 probe.

Time frame
Single assessment during the study visit
3

Change in Skin Erythema

Skin erythema will be assessed using a Mexameter MX 18 probe.

Time frame
Single assessment during the study visit
