Common Name(s): Milk exosomes,milk exosomes,extracellular vesicles,nano cell communication carriers
CAS Number: N/a
DESCRIPTION
What It Does: Provides naturally packaged microrna and growth factor delivery via exosomal lipid bilayer vesicles for skin cell communication, collagen gene modulation, and barrier repair.
Why It's Used: Milk exosomes are selected for their natural nano-carrier architecture โ the lipid bilayer vesicle structure provides protected delivery of mirna cargo to skin cells that penetrates the sc barrier and reaches fibroblasts, modulating gene expression through mechanisms inaccessible to conventional actives.
How It Works: Milk exosomes: lipid bilayer vesicle (80-150 nm) โ sc penetration via follicular route โ fusion with keratinocyte membrane โ mirna release โ mrna target degradation โ gene expression modulation โ collagen/elastin synthesis.
Typically Found In: Anti-aging,premium skin care,cell communication

SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low
Comedogenicity Rating: 0/5 โ non-comedogenic
Sensitivity Concerns: Non-irritating; beneficial for sensitive skin.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Excellent safety profile. ewg score: 1.
Works Well With: Ceramides,niacinamide,soothing actives
Avoid Combining With: No significant incompatibilities
SCIENTIFIC NOTE
Milk exosome bioactivity requires cold-chain preservation โ vesicle integrity is critical for mirna cargo delivery and degrades rapidly above 4ยฐc.
