Compatible & Safe to Layer — «Peptide Complexes (Matrixyl, Argireline, Signal Peptides)» and «Centella Asiatica / Cica (Madecassoside)» have no known negative chemical interactions and can be safely layered together.
Peptide Complexes (Matrixyl, Argireline, Signal Peptides)
Short-chain amino acids sending signals to skin cells to generate structural proteins and smooth expression lines.
Centella Asiatica / Cica (Madecassoside)
Legendary botanical soother. Neutralizes irritation from retinoids/acids, repairs micro-tears, and calms flushing.
💡Dermatologist Protocol (How to Combine):
Layer by texture consistency: apply thin, water-based serums first, followed by heavier creams and oils.
⏱️Which Goes First? (Layering Sequence):
Signaling Peptides (Matrixyl, Argireline) and Centella Asiatica (CICA) pair seamlessly in the same routine. Following the dermatological thinnest-to-thickest rule: apply "Signaling Peptides (Matrixyl, Argireline)" as Step 1, allow 1–2 minutes to absorb, and follow with "Centella Asiatica (CICA)" as Step 2.
⚗️pH Acidity Spectrum: Signaling Peptides (Matrixyl, Argireline) vs. Centella Asiatica (CICA)
Healthy skin barrier maintains a natural acid mantle between pH 4.7 and 5.5. Large pH discrepancies between layered products can destabilize actives or trigger stinging.
