Brief Summary

Goal is to investigate the differences in skin condition and body composition among women with different dietary habits aged 30-45 years. Study will be focused onto sub-groups of female subjects following omnivorous, vegetarian or vegan diet.

Conditions

Skin Condition; Body Composition

Outcome Measures

Primary Outcomes (7)

• Dermal density

  It will be measured on forearm using ultrasonography as score 0-100.

  baseline

• Dermal thickness

  It will be measured on forearm using ultrasonography in micrometeres.

  baseline

• Skin hydration

  It will be measured on forearm using Cortex DermaLab flat hydration probe in microsiemens.

  baseline

• Skin elasticity

  It will be measured on forearm using Cortex DermaLab elasticity probe in MPa.

  baseline

• Trans epidermal water loss

  It will be measured on forearm using Cortex DermaLab open-chamberTEWL probe.

  baseline

• % of lean body weight

  It will be measured using Multiscan is a spectroscopy (BIS).

  baseline

• % of body fat

  It will be measured using Multiscan is a spectroscopy (BIS).
