CRITHMUM MARITIMUM EXTRACT.

Valuable CAS 89997-98-8 / SKIN CONDITIONING, TONIC

Commonly known as Sea Fennel, this resilient maritime botanical is a bio-retinoid alternative that mimics the skin-renewing effects of Vitamin A without the associated irritation. It is a powerhouse of phenolic compounds and essential fatty acids that bridge the gap between barrier protection and cellular regeneration.

Retinoid-like Regenerator Antioxidant Barrier Fortifier Sebum Regulator

Science

It functions via a multi-pathway approach: stimulating the proliferation of keratinocytes to thicken the epidermis and boosting the synthesis of Collagen I and Loricrin for structural integrity. By utilizing plant stem cells, it activates the skin's internal renewal processes, regulates sebum production for a mattifying effect, and provides robust antioxidant defense against lipid peroxidation.

Key findings

  1. 01 A 3D full-skin model study using full-component extract demonstrated a 19.93% increase in epidermal cell thickness and a 47.62% improvement in collagen fiber density.
  2. 02 Research indicates a 26.92% boost in Loricrin (LOR) content, essential for cornified envelope formation and barrier function.
  3. 03 Collagen I synthesis was measured at a 15.85% increase, supporting dermal elasticity and contour definition.
