Science

This advanced lysate stimulates the proliferation of epidermal stem cells, thereby rejuvenating the skin's inherent renewal potential and accelerating the epidermal turnover rate. Studies indicate it significantly enhances the synthesis of hyaluronic acid within 3D epidermis models and increases epidermal thickness by up to 88% under pro-aging conditions. Rich in phenolic compounds such as rosmarinic and caffeic acids, it also provides antioxidant and calming benefits, actively combating visible signs of aging and supporting overall skin health.

As of the latest review (2022-2023), the independent Cosmetic Ingredient Review (CIR) panel has not yet evaluated Symphytum officinale callus culture extract. It is noteworthy that while traditional comfrey extracts may contain pyrrolizidine alkaloids associated with irritation, the callus culture lysate is specifically formulated to mitigate these concerns, contributing to its low irritancy profile.
