PALMITOYL HEPTAPEPTIDE-27.

Valuable / SKIN CONDITIONING

Palmitoyl Heptapeptide-27 is a sophisticated biomimetic lipo-peptide engineered to enhance the skin's natural barrier function. It actively signals keratinocytes to boost the production of vital structural proteins like filaggrin and loricrin, crucial for robust skin integrity and optimal hydration.

Science

Mechanism of Action

This synthetic lipo-peptide functions by mimicking natural signaling pathways within the skin's keratinocytes. It specifically upregulates the synthesis of filaggrin and loricrin, two essential proteins for epidermal health. Filaggrin plays a key role in structuring keratin fibers and producing natural moisturizing factors (NMFs) such as PCA, which are vital for maintaining skin hydration. Loricrin contributes to the protective envelope of cornified cells, strengthening the skin's defense against environmental stressors. This targeted action supports overall barrier strength and resilience, particularly when synergistically combined with other peptides.
