This is a single centre, 5-cell, blinded study to evaluate changes in even skin tone, skin glow, facial pigmented spots, and the microbiome of facial skin following the use of cosmetic face care products on the whole face over a 12 week period.

The goal of this study is to investigate if a food ingredient can improve stress in healthy adults who experience moderate symptoms of self-reported stress. The main question it aims to answer is if 4 weeks of daily intake of the ingredient reduces stress compared to 4 weeks of daily intake of a placebo product.
Participants will:
consume both the test and placebo products for 4-weeks each in a randomised order, with 4 weeks in between
visit the test site 6 times over the 13 weeks
complete a series of assessments on stress and sleep quality and provide blood, stool and saliva samples

The goal of this 4-arm randomized controlled trial is to test the effectiveness of two positive body image media micro interventions (a tv show and a music video) in improving body image related constructs.
The main questions this study aims to answer are:
Relative to time-matched active controls, are the two positive body image media micro-interventions effective in yielding immediate improvements in children's body functionality appreciation and body appreciation and in reducing anti-fat attitudes?
Are the two positive body image media micro-interventions acceptable to children and their participating parent/guardian?
An additional five secondary exploratory research questions are described below [in the description section].
Participants will be recruited into the trial by a research agency via their parents/guardians. Once recruited, they will be randomised into one of 4 conditions:
15-minute TV intervention
15-minute active TV control
3-minute music video intervention
3-minute active music video control
Children (and their parent or guardian) will visit a testing centre in groups of approximately 12 dyads. Children will complete T1 assessment interviews one-on-one with a researcher, before watching their assigned media with their parent. After watching their assigned media, children will complete their T2 assessment, again one-to-one with a researcher, while parents complete a survey regarding their acceptability of the media they watched. Parents/guardians will be given a link to rewatch their assigned media and encouraged to rewatch with their child before returning to the testing centre approximately one week later. When children and parents/guardians return one week later, the child will complete T3 assessment interviews one-to-one with a researcher, and parents will complete a short survey regarding their rewatch habits.
Researchers will compare the two positive body image media micro-interventions with their time-matched active controls to examine if they are effective in yielding immediate improvements in children's body functionality appreciation and body appreciation and in reducing anti-fat attitudes.
