Presentation Transcript

  1. Skin Structure Epidermis Dermis

  2. 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 Stratum Corneum Transitional Layer Stratum Granulosum Stratum Spinosum Basal Layer

  3. Epidermis

  4. Skin Structure (Dermis) Papillary Dermis Reticular Dermis

  5. Collagen

  6. 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 Farnesol – signal presence to make collage; farnesylation of dermal proteins Niacinamide – increase collagen production; increase DNA synthesis & cell growth Pentapeptide- Signal to make collage; stimulates release of growth factors from dermal matrix -> generation of new matrix; reductions of GAGs
