Marine algae have evolved UV-protective compounds, antioxidant systems, and moisture-retention mechanisms that translate directly to skin benefits.
Botanical Peptides vs. Synthetic Peptides: What's the Difference?
Plant-derived signalling molecules versus lab-engineered amino acid chains. Both have merit, but their mechanisms and skin compatibility differ in important ways.
Why Weekly Exfoliation Outperforms Daily Scrubs
Daily physical scrubs create micro-tears. Weekly chemical exfoliation removes dead cells without compromising the barrier. The difference is structural.
