Glycation is a reaction that happens both inside and outside of our bodies. It is a process by which sugars (primarily fructose and glucose) bond with proteins and fats to form advanced glycation end-products, or A.G.E. These pro-inflammatory compounds can cause the all-important collagen and elastin in our skin to become weak and stiff, accelerating the visible signs of aging. Although a certain amount of sugar is necessary for healthy body function, it has been asserted that a low glycemic diet is a beneficial part of any anti-aging regimen.
Because these A.G.E. also induce a browning reaction (called a Maillard reaction, as it was discovered by chemist Louis-Camille Maillard in 1912), they are often added to many foods we consume to improve their color, taste and appearance. Unfortunately, this is clearly a sales and marketing benefit, not a health benefit. High levels of A.G.E. are being studied for their role in type II diabetes, ocular diseases and heart diseases.
Below is a list of some ingredients in our products that are found to help fight the visible skin aging that can be exacerbated by glycation:
- Aminoguanidine (Nutrient Toner, A&C Synergy Serum®)
- Arginine (Perfecting Protection Broad Spectrum SPF 30, Body Therapy, A&C Synergy Serum®, Intensive Clarity Treatment: 0.5% pure retinol night)
- Niacinamide (ReBalance, Rejuvenating Serum, Hydrating Serum, Pigment Bar®, Activator (Step 1 from the Oxygenating Trio))
- Green Tea Extract, Flavonodis, Antocyans – different polyphenolics (these are found in a wide range of PCA SKIN products)
