Doctors, dentists, and nutritionists agree that limiting sweets contributes to overall health and vibrancy. Sugar's impact on the skin is significant, making it a key factor in the aging process. This is where glycation comes into play.
Glycation is a natural process triggered by sugars like glucose and fructose. When excess sugar accumulates in skin fibers, sugar molecules attach to collagen and elastin proteins. This leads to inflammation and visible signs of skin aging.
Understanding Glycation
Glycation occurs when sugar molecules bind to proteins, lipids, and nucleic acids, forming advanced glycation end products (AGEs). AGEs accumulate over time in the skin and contribute to wrinkles, loss of elasticity, and a dull complexion. This process typically begins around age 20 and gradually intensifies. Factors such as UV radiation, smoking, and high dietary sugar intake can accelerate AGE formation in the skin, resulting in a loss of firmness and elasticity.
The Formation of AGEs
The glycation process causes advanced glycation end-products (AGEs) to form in the skin. AGEs make collagen rigid over time, reducing its ability to keep skin bouncy. This results in fine lines and wrinkles as the skin loses its natural structural support. AGEs also interact with receptors in the skin, kicking up inflammation and leading to dryness or discomfort.
How AGEs Damage the Skin
AGEs not only degrade collagen and elastin but also trigger oxidative stress and inflammation by binding to AGE receptors, known as RAGE. This accelerates visible aging signs, making skin appear tired and less resilient. AGEs damage cellular machinery, inhibit cells' ability to perform basic functions, and make them behave as if they were much older. Glycation can interrupt the skin's renewal process by reducing the body's ability to create important skin constituents like collagen.

The Effects of Glycation on the Skin
The effects of glycation on the skin include:
Loss of Elasticity: Glycated collagen and elastin lose their ability to function properly, resulting in decreased skin elasticity. This leads to sagging and the formation of fine lines and wrinkles.
Decreased Radiance: Glycation can cause the skin to appear dull and lackluster. The accumulation of AGEs impairs the skin’s ability to reflect light, leading to a less vibrant complexion.
Increased Skin Fragility: Glycation weakens the skin’s structure, making it more susceptible to damage from environmental factors such as UV radiation and pollution. This can result in increased sensitivity and a higher risk of developing conditions like rosacea and eczema.
Slower Wound Healing: The presence of AGEs can slow down the skin’s natural healing process, making it more difficult for the skin to recover from injuries or inflammation.

Anti-Glycation Skincare: A Proactive Approach
To combat glycation and its aging effects on your skin, it's essential to adopt a proactive approach with your daily skincare routine. If you are concerned about premature aging, dullness, or loss of skin firmness, incorporating an anti-glycation skincare routine may be beneficial.
Key Anti-Glycation Skincare Ingredients
Traditional anti-glycation skincare ingredients primarily function as antioxidants that prevent AGE formation. Here are some effective ingredients to look for:
Carnosine: Carnosine inhibits the formation of AGEs by preventing the cross-linking of proteins induced by glycation. Carnosine also acts as an antioxidant, helping to combat the effects of free radicals on your skin and minimize the visible signs of aging. Glucose molecules stick to carnosine instead of collagen, slowing down the glycation process.
Algae Extracts: Algae extracts, particularly those derived from brown and red algae, contain polysaccharides and peptides that interfere with the glycation process, thereby mitigating the formation of AGEs. Algae extracts also stimulate the synthesis of collagen and elastin, offering a dual benefit by not only preventing glycation but also promoting the repair and maintenance of skin structure.
Resveratrol: Resveratrol modulates the expression of genes associated with glycation and AGE formation, thereby reducing the impact of glycation on the skin's extracellular matrix. Resveratrol exhibits anti-inflammatory and antioxidant properties, further shielding the skin from the detrimental effects of glycation.

Green Tea Polyphenols: Epigallocatechin gallate (EGCG) inhibits the generation of AGEs and suppresses the activation of pathways associated with glycation-induced skin aging. Green tea polyphenols possess antioxidant and anti-inflammatory properties, contributing to their efficacy in countering the effects of glycation on the skin.
Hexapeptide-3: This power peptide promotes restructure and repair.
Incorporating Anti-Glycation Ingredients into Your Routine
Here are some recommended products and ingredients to look for:
Antioxidant Serums: Products containing a high concentration of antioxidants can help combat oxidative stress and neutralize free radicals. Look for serums with vitamin C, vitamin E, and ferulic acid for maximum efficacy.
Peptide Creams: Peptides are small chains of amino acids that can stimulate collagen production and improve skin elasticity. Products containing peptides, such as Matrixyl and Argireline, can help counteract the effects of glycation on the skin.
Retinoids: Incorporating retinoids into your nighttime skincare routine can help reduce the visible signs of glycation and promote healthier, more resilient skin.
Anti-Glycation Formulas: Look for skincare products specifically formulated to combat glycation. These products often contain ingredients like carnosine, which can inhibit the formation of AGEs and protect the skin’s structural proteins.
Hydrating Moisturizers: Keeping the skin well-hydrated is essential for maintaining its health and resilience. Moisturizers containing hyaluronic acid and ceramides can help strengthen the skin barrier and improve its ability to retain moisture.
Addressing Existing AGEs
Incospharm developed an anti-glycation ingredient, ICP De-Age I, inspired by its prior research and advancements in the field of autophagy. ICP De-Age I has the additional function of eliminating existing AGEs, effectively reversing glycation. Clinical studies reported that the active was able to reduce AGE levels by 8.49% in two weeks and 13.36% in four weeks. ICP De-Age I was also able to reduce RAGE in skin, which in turn helps to mitigate the skin’s inflammatory responses.
The Role of Diet and Lifestyle
Managing blood sugar levels can reduce glycation and its effects on your skin. A healthy, balanced diet is the best place to start. Be sure to grab coconut oil or ghee to cook safely. Olive oil and others cause glycation under med-high heat.
Dietary Adjustments: Reducing the intake of sugar and processed foods can significantly lower the formation of AGEs. Incorporating a diet rich in antioxidants, such as fruits and vegetables, can help neutralize free radicals and reduce oxidative stress. Historically, when our ancestors ate sugar, they did so in the form of fruit. Yes, fruit contains sugar, but it also carries with it a host of other constituents which naturally block glycation processes in the body. Because modern diets are low in whole plant food, the chance of glycation occurring is much higher.
Sun Protection: Remember to wear broad-spectrum sunscreen every day. UV rays can accelerate the formation of AGEs and exacerbate the degradation of collagen and elastin. Using a broad-spectrum sunscreen with an SPF of at least 30 can provide effective protection against UV-induced glycation.
