What are the active ingredients used to anti-glycation of skin?

Skin Glycation: An Overview

Skin glycation is a biochemical process that occurs when sugar molecules, such as glucose and fructose, bind to proteins, lipids, and nucleic acids, forming advanced glycation end products (AGEs). This process is accelerated by factors such as UV radiation, smoking, and dietary sugar intake. In the context of skin aging, glycation contributes to the formation of cross-linked proteins, ultimately leading to the degradation of collagen and elastin, which are essential for skin structure and elasticity. The visible outcomes of glycation on the skin include the formation of wrinkles, fine lines, and a loss of firmness.

Effective Anti-Glycation Ingredients in Cosmetic Formulations

There are many ingredients with anti-glycation functions, and they often overlap with antioxidant, anti-aging, anti-wrinkle, repairing and whitening ingredients.

Carnosine

Carnosine, a dipeptide composed of beta-alanine and histidine, has emerged as a potent anti-glycation agent in cosmetic formulations. Studies have demonstrated its ability to inhibit the formation of AGEs by preventing the cross-linking of proteins induced by glycation. Furthermore, carnosine has shown antioxidant properties, protecting skin proteins from oxidative damage caused by glycation, thus preserving the structural integrity of the skin.

Algae Extracts

Algae extracts, particularly those derived from brown and red algae, have gained attention for their anti-glycation properties. These extracts contain polysaccharides and peptides that interfere with the glycation process, thereby mitigating the formation of AGEs. Additionally, algae extracts have been found to 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, a polyphenolic compound found in various plants including red grapes and Japanese knotweed, has demonstrated remarkable anti-glycation effects. It functions by modulating the expression of genes associated with glycation and AGE formation, thereby reducing the impact of glycation on the skin's extracellular matrix. Moreover, resveratrol exhibits anti-inflammatory and antioxidant properties, further shielding the skin from the detrimental effects of glycation.

Green Tea Polyphenols

The polyphenolic compounds present in green tea, particularly epigallocatechin gallate (EGCG), have shown promise as effective anti-glycation agents in cosmetic formulations. EGCG has been shown to inhibit the generation of AGEs and suppress the activation of pathways associated with glycation-induced skin aging. Additionally, green tea polyphenols possess antioxidant and anti-inflammatory properties, contributing to their efficacy in countering the effects of glycation on the skin.

Will Polysaccharides in Cosmetics Accelerate Glycation?

The presence of polysaccharides in skin care products and cosmetics has raised concerns regarding their potential participation in glycosylation, the non-enzymatic reaction between sugar molecules and proteins or lipids in the skin. However, it is essential to note that the molecular size and structure of sugars in skincare formulations are tailored to ensure optimal skin penetration and efficacy without inducing glycation. For instance, sugar alcohols such as sorbitol and xylitol are commonly used in skincare formulations as humectants due to their ability to attract and retain moisture. These sugar alcohols have larger molecular structures, which cannot penetrate the barrier and be absorbed by the skin.
