Healthy, beautiful skin On a journey through time
Evolution of Skin Care:The Beginning • Affordable common soap • Increased hygiene and fewer skin infections • Soap removed too much sebum and yielded dry skin
Evolution of Skin Care:The Beginning • Moisturizers needed to counteract the drying effect of soap • Original moisturizers were petroleum, lanolin • Greasy substances prevented moisture from evaporating from the skin
Evolution of Skin Care:The Present • Refined cleansers that provide excellent hygiene, but do not overdry the skin • Elegant moisturizers that hydrate and retard moisture loss • Sunscreens that prevent sunburn and function to counteract the aging effects of UV exposure
Present Skin Care Philosophy • Add to the skin what is missing • Sophisticated cosmeceutical moisturizers to add vitamins and antioxidants (skin care maintenance) • Sunscreens to add additional protection from aging (skin care prevention)
Future Skin Care Philosophy • Adding and supplementing the skin for prevention and maintenance purposes is important • The step beyond is removal of substances that retard optimal skin functioning • Add the good, remove the bad
Critical Questions • What should you add to the skin and what should you remove? • How do you know what is good and what is bad? • How do you remove substances from the skin that promote aging?
Skin Aging Concepts • Skin ages due to UV damage, oxidation • Oxidation by products accumulate • Skin aging progresses as byproducts decrease optimal functioning
Satisfied Oxygen Atom Crippled “Free Radical”
Antioxidants lose an electron without initiating a chain reaction. Antioxidants inhibit lipid bi-layer and cell membrane breakdown.
Future Skin Care: Adapting New Technology to Skin • Rate of tissue aging is slowed in laboratory by placing tissue in special transport media • Transport media contains substances to remove byproducts from the tissue • Tissues age at a slower rate due to optimal functioning
Evolution of Skin Care:The Future • Important active ingredient in transport media is lactobionic acid • Minimize the damaging effects of: • Oxygen and other pro-oxidants • Transitional metals, such as iron
Evolution of Skin Care:The Future • New skin care products utilize transport media technology to aid in the prevention of aging • Active ingredients placed in moisturizers to hydrate skin • Adding the good and removing the bad
The Future is Now • Add to the skin • sun protection • skin moisturizers • skin antioxidants • Remove from the skin • sebum and environmental dirt • damaging byproducts
Evolution of Hydroxyacid Skin Care AHAs (glycolic acid, lactic acid) PHAs (gluconolactone) New Bionic PHAs (lactobionic acid)
AHA vs. PHA • glycolic acid gluconolactone CH OH 2 O H COOH H O H OH H OH C OH H H OH
PHA: Gluconolactone • Polyhydroxy AHA (PHA): full strength anti-aging benefits • Natural component of skin; cell nutrient • Natural antioxidant/chelator • Highly moisturizing • Strengthens skin barrier (published study) • Non-stinging, non-burning • Suitable for all skin types including sensitive skin • No increase in sun sensitivity
Gluconolactone - Chelator • Dairy - prevents milk stone • Brewery - prevents beer stones • Foodstuffs - coagulant for tofu • Humans - acidify urine to allow exchange of Mg++ for Ca++ in kidney stones
Lactobionic Acid(Bionic PHA) • Anti-aging effects (it is an AHA) • Gentle to skin • Plumps the skin • Provides unique skin feel attributes – gel/film forming property • Suitable for all skin types, even sensitive skin • Moisturizing/water binding: 8 hydroxyl groups
Weight (g) of water absorbed per mole of substance* *After exposure to 100 % relative humidity for four hours.
Lactobionic Acid – Skin Protector! • Antioxidant • Medical use - preservative for organs during transplantation procedures – it traps metals • Inhibitor of metalloproteinase enzymes (MMPs) • MMPs degrade skin collagen • Leads to wrinkles, laxity, visible capillaries • UV and aging MMP activity
