How will your skin travel through time?

Zoe Diana Draelos, M.D.

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”

Free Radical Chain Reaction

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

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

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
