Skin Hydration

his observational study examines whether time spent driving is associated with differences in skin hydration between the left and right cheeks in female drivers residing in Florida. In left-hand-drive vehicles, the driver's left cheek is chronically exposed to ultraviolet A (UVA) radiation through the unshaded side window during every daytime driving episode. A prior study by IAS Skin Care (NCT07564869, n=30) found that the left cheek was less hydrated than the right cheek in 60% of participants, suggesting a possible effect of driving-related UVA exposure on facial skin hydration asymmetry. Eighty female drivers aged 25-65 years residing in Florida will be enrolled. At a single visit, skin hydration will be measured at three facial zones (left cheek, right cheek, and forehead as a symmetrical control zone) using the BT-Analyze bioimpedance device. Participants will complete a structured questionnaire on driving habits, sun protection practices, and skin history. The primary outcome is the Hydration Asymmetry Index (HAI = right cheek minus left cheek BT-Analyze score). Associations between driving time, cumulative driving exposure, window tinting, sunscreen use, and HAI will be examined using Spearman correlation, Mann-Whitney U tests, and multiple linear regression.

This is a single-group, open-label, virtual (decentralized) clinical trial evaluating the effects of Naila's Collagen Marine Plus Food Supplement on skin hydration, elasticity, firmness, fine lines and wrinkles, and hair and nail health over 12 weeks. Forty healthy adults aged 40-60 years with self-reported mature skin showing early signs of aging will take one sachet of the supplement daily and complete questionnaires at Baseline, Week 4, Week 8, and Week 12. Participants will also submit standardized facial and hair photographs at Baseline and Week 12 for evaluation by a board-certified dermatologist. The primary objectives are to assess changes in skin aging parameters and hair health. Secondary objectives include evaluation of nail health, hair shedding and density, participant-reported satisfaction, and product safety and tolerability.

The goal of this clinical trial is to evaluate whether a topical face cream containing the peptide Acetyl Hexapeptide-37 improves skin hydration and strengthens the skin barrier compared to a placebo cream in healthy adult participants. The study uses a split-face design, in which one side of the face is treated with the peptide cream and the other side with a placebo (a cream without the active ingredient). The main questions it aims to answer are: * Does the peptide cream improve skin hydration and reduce transepidermal water loss compared to placebo? * Does the peptide cream affect skin erythema or cause irritation? * How do participants rate the comfort and tolerability of the peptide cream? Researchers will compare the treated and placebo sides of the face to assess differences in skin barrier function and tolerability. Participants will: * Attend a baseline visit for assessment of facial skin parameters, including hydration, transepidermal water loss, and erythema * Apply the peptide cream to one side of the face and the placebo cream to the other side once daily for 4 weeks * Attend weekly follow-up visits for non-invasive skin measurements * Record any skin sensations (e.g., stinging, tightness) or adverse effects throughout the study

This is an exploratory, cosmetic-use study evaluating the effects of Super Protein Multifunction (SPM™), a topical peptide-based formulation, on skin appearance, hydration, and barrier-related characteristics in healthy adults. The study aims to collect preliminary biophysical and histologic data on cosmetic skin changes following six weeks of SPM™ use. Participants will apply the product to a designated skin area while a matched contralateral area serves as the untreated comparison site. Skin hydration, transepidermal water loss (TEWL), and tissue markers of skin structure and barrier integrity will be assessed before and after product use. The study includes noninvasive measurements and small punch biopsies at two timepoints.
