SkinSpirit,Palo Alto:SkinCeuticals-Sun Protection,Vitamin C,Primacy

The goal at SkinCeuticals is to provide you with quality products backed by science. Unlike most skin care companies, SkinCeuticals devotes countless resources toward research at major medical institutions to support the technology behind their products.

SkinSpirit offers selections from SkinCeuticals product line with the following science behind it:

VITAMIN C SCIENCE

Researchers now know that aging skin is the result of more than just chronological age. Everyday your skin is exposed to environmental elements like sunlight, smoke, and air pollution - elements that cause oxy radicals to form in the skin. These oxy radicals attack the skin's collagen layer and break it down, causing lines and wrinkles to appear. This process is commonly called photo-aging.

Clinical evidence shows that precise applications of anti-oxidants can help prevent photo-aging in skin. Recent research conducted by Dr. Sheldon Pinnell at Duke University Medical Center shows that applying vitamin-C to the skin can:

• Provide anti-oxidant protection

• Prevent photo-aging

• Stimulate collagen production

However, not all vitamin-C formulations can produce these benefits. Dr. Pinnell's studies show that in order to be effective, a vitamin-C formulation must contain several precise characteristics.

• It must contain L-ascorbic acid. L-ascorbic acid is the only form of vitamin-C that can be used by the body.

• It must be formulated at acid pH, otherwise the vitamin-C will not be absorbed by the skin.

• It must contain at least a 10% concentration of vitamin-C.

• It must be stable.

PRIMACY SCIENCE

After years of research perfecting our remarkable stability technology, we are now able to formulate ingredient combinations that were previously thought to be impossible - combinations such as vitamin-C and vitamin-E, or vitamin-C and alpha-hydroxy acids. These innovations resulted in PRIMACY, a highly effective line of advanced skin care treatments with unparalleled formulation technology.

Primacy contains some of the highest levels of antioxidant protection available. Primacy means higher concentrations, pure bio-available ingredients, and unparalleled stability technology, all supported by clinical research at top medical institutions.

PHYTO SCIENCE

Normal skin color is formed by melanin, a natural pigment that also determines hair and eye color. Melanin is created when the enzyme tyrosinase converts the amino acid tyrosine into melanin. When too much melanin is produced, deposits are formed and hyper-pigmentation appears in the skin.

Arbutin from the Uva-Ursi plant and thymol from the Thyme plant intercept tyrosinase, helping to prevent new brown spots from appearing. These two ingredients also help prevent the appearance of additional hyper-pigmentation.

SUN PROTECTION SCIENCE

While scientists have long known that sun exposure can have harmful effects on the skin, new research shows that UVA rays are responsible for premature signs of aging in skin, while UVB rays are responsible for burning. Surprisingly, most sunscreens don't protect skin from UVA rays. To protect yourself from further deterioration, it is essential to wear a broad spectrum (UVA/UVB) sunscreen. SkinCeuticals sun protection products contain Z-Cote, a form of microfine, transparent zinc-oxide which provides true broad spectrum UVA/UVB protection. Unlike the pasty white zinc-oxide sunscreens of the past, our sunscreens are cosmetically elegant and perfect for use under make-up or other cosmetics.
