What are peptides, and why do they matter in skincare?
Peptides are short chains of amino acids, the building blocks of proteins like collagen and elastin, which help keep skin firm, smooth and healthy. As the natural production of collagen and elastin decreases over time, peptides in skincare function as signaling molecules that help activate stimulation of these proteins. Skin is firmer, more hydrated and resilient, and visible signs of aging are reduced.

Will BioComplexe PX in these products irritate my skin?
BioComplexe PX, our proprietary blend of natural silk peptides that works with your skin, not against it, was designed to deliver visible results without causing irritation, redness or discomfort. In addition to BioComplexe PX, the products in this bundle are powered by non-irritating ingredients such as Allantoin, Aspen Bark Extract and Panthenol. Allantoin is a gentle skin soother that comforts, calms and supports skin regeneration. Aspen Bark Extract is a gentle plant based exfoliant that naturally soothes and smooths skin without irritation. Panthenol is a gentle ingredient that calms and restores the skin barrier while delivering lasting hydration. In case of any concerns, we always recommend testing any new product on a patch of skin such as your wrist before applying liberally to your face, or consulting with your dermatologist first.

Does BioComplexe PX use natural ingredients?
Yes. BioComplexe PX contains peptides derived from natural silk, created by upcycling discarded silk cocoons to extract silk protein, alongside other natural ingredients. These silk peptides are biodegradable, upcycled, and sustainably sourced, proving that powerful science can be gentle on your skin and the planet.
