The purpose of this clinical trial is to evaluate whether nutritional supplementation over a 2-month period improves skin physiological parameters. This is a national, single-center, double-blind, randomized pilot study.
The study will be conducted using a supplement and a placebo, the safety of which has been assured by the sponsor.
Participants will:
* Take a food supplement or a placebo once daily for 2 months
* Visit the study center at beginning, after 28 days and after 56 days of supplementation.
* Keep a diary of their skin status and tolerability
The secondary objective is to evaluate product characteristics and performance during normal use in healthy subjects.

The aim of this study is to investigate the effects of 15 mg/kg lemon verbena, in comparison to placebo, on the attention deficit hyperactivity disorder (ADHD) type behaviour and cognitive function of children who do not have a diagnosis of ADHD, but who exhibit high scores (highest tertile) on ADHD behaviour parameters. Multiple aspects of mood will also be assessed.
The proposed randomised, double-blind, placebo-controlled, parallel groups design methodology will assess the psychological effects of 15 mg/kg lemon verbena extract and a matched placebo prior to and after 4 and 8 weeks of supplementation. The trial will utilise the COMPASS cognitive assessment system (Northumbria University) and a range of mood measures during laboratory testing visits.
Parents and children will also take part in a concomitant smartphone study, comprising the collection of the parent's assessment of the child's behaviour/cognitive function and the child's self-report of the same, plus their mood. These assessments will take place on Days -1, 14, 28, 42 and 56.
