Epidermis

• Differentiation
• Cells move from basal layer to stratum corneum
• Synthesis modification of proteins, especially
  keratins
• Appearance of new organelles, reorganization of
  organelles, loss of organelles
• Change in cell size shape
• Changes in properties of membranes
• Dehydration
• Desquamation

Ingredient Mechanisms
Super Sterol Ester SEFA- hydration barrier
repair
Farnesol Precursor in biosynthesis of lipids
sterols farnesylation of epidermal proteins
Epidermis
Niacinamide increase growth differentiation
Allantoin promotes normal keratinization
Dermis
Anti-oxidants Vitamin E Green Tea Extract
scavengers of free radicals
Niacinamide increase collagen production
increase DNA synthesis cell growth
Farnesol signal presence to make collage
farnesylation of dermal proteins
Pentapeptide- Signal to make collage stimulates
release of growth factors from dermal matrix -gt
generation of new matrix reductions of GAGs
