THE SCIENCE BEHIND OUR PRODUCTS
At Phyto-C Skincare, vitamin C is not merely a step in one’s skin care regimen. It is an integral part of a skincare regimen. Why? Vitamin C is well known for it’s antioxidant properties and is a key ingredient that increases the potency and eﬃcacy of the other key ingredients in many of our other skin care products. Dr. Mostafa Omar, President and founder of Phtyo-C Skin Care and inventor of topical Vitamin C, develops each and every formula with safety, efficacy, and purity to relieve the appearance of major skin concerns.
L-Ascorbic Acid (vitamin C)
L-Ascorbic acid (LAA), is the foundation of which Phyto-C Skin care was built on. Phyto-C’s high-concentration antioxidants are designed for optimized absorption on skin and proven in published, peer-reviewed scientific journals. Our Vitamin C serum’s reducing the appearance of fine lines, wrinkles, and discoloration. The highest concentration of L-Ascorbic Acid clinically proven to penetrate the skin is 20%. Any product claiming to contain more than 20% L-Ascorbic Acid will not penetrate the skin and will see no results. A pH of 3.5 or lower is essential for L-Ascorbic absorption. After only three days of applying topical L-Ascorbic Acid to the skin, tissue levels will be saturated and levels have been found to be approximately 20 times the normal tissue level. L-Ascorbic Acid remains in the skin for approximately four days after topical application.
Percutaneous Skin Absorption and Its Importance
Cosmetic substances navigate through the skin primarily through the pores of the hair follicles, the sweat glands, or through the protein/lipid domains of the stratum corneum. In the initial transient diffusion stage, penetration occurs through the hair follicles and the ducts. Water-soluble molecules with low lipid solubility will usually pass through the pores, whereas lip-soluble materials pass through protein/lipid domains of the stratum corneum.
Percutaneous absorption involves the following:
- Partitioning of the molecule into the stratum corneum from the applied vehicle phase
- Molecular diffusion through the stratum corneum
- Partitioning from the stratum corneum into the viable epidermis
- Diffusion through the epidermis, the upper dermis, and the capillary uptake.
Phyto-C’s products have been clinically tested and peer reviewed for their ability to penetrate the skin for maximum efficacy in relieving the appearance of common dermatological sin conditions.
Olive Leaf Extract
The ancient Egyptians were the first to use Olive Leaf Extract. Olive Leaf Extract is derived from the olive tree (Olea Europaea) and contains Oleuropein which has powerful antioxidant properties to assist in improving the look of fine lines, wrinkles, irritated an dry skin.
Figure 1 shows enhanced levels of antioxidant protection provided when combining Olive Leaf extract, Vitamin A, Vitamin C, and Vitamin E compared to those of the vitamins and extracts in different combinations.
