What the brand claims
In the brand’s own words, quoted as written.
“Infused with Life Plankton™ and Algae of Youth, the Biotherm Blue Therapy Accelerated Anti-Aging Serum delivers targeted support for visible signs of aging. Formulated to reduce the appearance of fine lines, dark spots, and loss of firmness, it provides immediate softness and suppleness while replenishing moisture with a lightweight, fast-absorbing texture.”
