What the brand claims
In the brand’s own words, quoted as written.
“Aquasource Hydra Barrier Cleanser is a cream-to-foam formula that gently cleanses while supporting the skin’s natural barrier. Enriched with Biotech Plankton™, Bio-Ceramides, and Niacinamide, it helps reduce tightness and redness with regular use, leaving skin refreshed and balanced. The soap-free, 99% biodegradable formula is designed for sensitive skin and is packaged in a tube made with 24% recycled plastic and a cap made from 100% PCR recycled plastic.”
