How are sugar and collagen linked to skin elasticity?

How is sugar related to collagen?

Alongside skincare and protein-containing foods, paying attention to sweetness in your daily diet is part of caring for yourself. Sugar can bind to parts of proteins through a process called glycation, which may change the structure of certain proteins, including collagen in the skin.

Glycation occurs naturally and accumulates with age, increasing with chronically high blood glucose. Take a long-term view rather than assuming one sweet meal immediately damages your skin.

How can skin structure change when sugar binds to proteins?

Think of collagen as a mesh supporting tissues. When proteins in this structure are modified, the fibres' properties can change.

1. Sugar binding to proteins, or glycation — Certain sugars can react with parts of proteins without enzymes, the substances that help speed up reactions in the body. This process does not occur only after eating a lot of sweet foods.
2. Compounds that form later, or AGEs — Some substances formed while sugar binds to proteins undergo further changes into a group called advanced glycation end-products, abbreviated as AGEs.
3. Effects on collagen — Some AGEs create more links between collagen fibres. Like adding fixed points to a mesh, this makes the structure stiffer and less flexible.

This mechanism is part of age-related changes in the skin. It helps explain long-term care, rather than promising a result from changing a single meal.

Reduce sweetness gradually, starting with foods you eat often

WHO recommends free sugars below 10% of total daily energy. Free sugars include those added to foods and drinks and those naturally present in honey, syrups, fruit juices and juice concentrates.

1. Start with drinks — Reduce the sweetness of your usual drink or choose water with some meals.
2. Check snacks and labels — note sugar and the amount you actually eat, especially for frequently chosen items.
3. Make sustainable changes — reduce one thing at a time while keeping food varied and sufficient, rather than pressuring yourself over a single meal.

Reducing sweetness and getting enough protein are different parts of caring for your diet. Protein supplies small units called amino acids to build and repair cells, while vitamin C is needed to make collagen.

Pro Cap: a rice and grain formula without mixing a drink

If you value simplicity and are interested in rice and grain ingredients, Pro Cap from GENISÉ offers capsules without another drink to prepare.

1. Know the ingredients — Brown rice, jasmine rice and glutinous rice combined with corn and soybeans in one formula.
2. ALS protein analysis — the submitted Pro Cap sample contained 56.6 grams of protein per 100 grams. Read the report using the link below.
3. Convenient for working days and travel — No mixing cup, measuring spoon or sweet drink needed. Carry in the original packaging and take as labelled.

Discover Pro Cap formula and view the ALS protein analysis

Use as a supplement according to the label, alongside adequate, varied main meals. Glycation information is nutritional knowledge, not evidence that Pro Cap reduces AGEs or restores skin collagen.

Frequently asked questions

Does sugar bind to proteins only when we eat a lot of sweet foods?

Sugar can bind to proteins naturally through a process called glycation, and its effects accumulate with age. Persistently high blood sugar can speed up this process, so consider diet and health over the long term.

Does free sugar mean only added sugar?

This includes sugars added to foods and drinks, as well as sugars naturally present in honey, syrups, fruit juices and juice concentrates. WHO recommends less than 10% of total daily energy.

How is Pro Cap convenient for people who do not want another drink to mix?

Pro Cap capsules combine three rice types with corn and soybeans. No measuring or drink mixing is needed. Take after meals as labelled.
