Plant-Based Skincare
Natural skincare is full of beautiful ingredient names. Rosehip. Calendula. Green tea extract. Vitamin C. The question is whether those ingredients are present in meaningful concentrations, and whether the evidence supports what the product claims they do.
This section evaluates plant-based skincare ingredients through biochemistry. I look at whether the chemistry behind an ingredient is sound, whether the concentration in a product is meaningful, and where the evidence supports or contradicts the marketing.
Plant biochemistry produces genuinely remarkable compounds. Polyphenols, terpenoids, fatty acids, polysaccharides. Many of these have real, documented activity in skin tissue at the right concentrations. The problem is that natural skincare formulations often include these ingredients at concentrations too low to do anything meaningful, or in forms that can’t penetrate skin effectively.
A product can list rosehip oil, green tea extract, and calendula on the label and still deliver none of their documented benefits if the formulation chemistry is wrong. This section looks at what the evidence actually shows, ingredient by ingredient.
