The problem it solves

Why this step exists, and what it changes.

Synthetic retinol works, but the initial weeks can be frustrating: redness, stinging, peeling skin, and an irritated barrier that forces you to hide under makeup. Most people quit before seeing results. Renewal Serum delivers the same structural benefits with zero downtime.

How it works on the skin

Powered by 2% Bidens Pilosa, a botanical extract whose phytanic acid docks with the same cellular retinoid receptors as traditional retinol. In lab studies, it stimulated collagen production by 32.5% and elastin by 25.2%, smoothing fine lines and refining coarse skin texture. Suspended in a soothing cushion of organic rosehip oil, murumuru butter, and hyaluronic acid, it nourishes the barrier while accelerating cellular turnover.

What is in it

  • 2% Bidens Pilosa ExtractPlant-based retinoid alternative that targets fine lines and loss of firmness without peeling or flaking.
  • Murumuru Seed ButterAmazonian tree butter rich in lauric and myristic acids that nourishes and protects skin elasticity.
  • Rosehip Fruit OilCertified organic oil packed with natural trans-retinoic acid precursors and essential omegas to fade post-blemish marks.
  • Hyaluronic AcidPlumps and hydrates to counteract the dryness common with cellular turnover treatments.
