Collagen and Skin Structure: What the Evidence Suggests
- LIVE
- EVIDENCE-INFORMED
Collagen is one of the most talked-about ingredients in skin health — and one of the easiest to oversell. We walk through what collagen structure and turnover actually mean, how collagen-focused interventions have been studied, and what the evidence does and does not support, without turning the topic into a product comparison.
Inflammatory Signaling and Skin: What the Evidence Suggests
- LIVE
- EVIDENCE-INFORMED
Inflammation is part of normal skin defense and repair — the question is what happens when those signals become excessive or poorly resolved. We examine how inflammatory signaling connects to barrier stress, matrix remodeling, and oxidative exposure, and why inflammation-related skin claims need compound-specific reading rather than broad category answers.
Micronutrient Sufficiency and Skin: What the Evidence Suggests
- LIVE
- EVIDENCE-INFORMED
Skin depends on vitamins, minerals, and related cofactors for normal biological work — but the evidence is more careful than a broad more-is-better promise. We look at how different nutrients connect to different parts of skin biology, why adequacy and enhancement are different claims, and what that distinction means for reading nutrient-based skin-health claims.
Oxidative Stress and Skin: What the Evidence Suggests
- LIVE
- EVIDENCE-INFORMED
Oxidative stress shows up in a lot of skin-health conversations — especially around antioxidants, sun exposure, and visible aging. We examine what oxidative stress actually means as a skin biology mechanism, where the evidence is genuinely useful, and why antioxidant claims need compound-specific reading rather than one universal answer.
Skin Barrier Integrity: What the Evidence Suggests
- LIVE
- EVIDENCE-INFORMED
The skin barrier helps hold water in, keep irritants out, and maintain a more resilient surface, and when it's disrupted, dryness, roughness, and reactivity often travel together. We look at how barrier function works, why it overlaps with hydration and inflammation without being the same as either, and how to read barrier-support claims more clearly.
Skin Hydration Systems: What the Evidence Suggests
- LIVE
- EVIDENCE-INFORMED
Skin hydration is more than drinking water, it depends on how well the skin retains, regulates, and protects water through barrier function, natural moisturizing factors, lipids, and cellular water handling. We look at how these systems work together, where the evidence is meaningful, and how to evaluate hydration claims more clearly.
