Collagen: Properties and Cosmetic Applications
What Is Collagen?
Collagen is a natural protein found throughout the body, particularly in connective tissue, skin, organs, muscles, bones and cartilage. There are more than 25 different types of collagen in the human body.
In the skin, collagen contributes to its structure, suppleness, flexibility and firmness, working together with elastin to support the skin's overall texture.
Collagen and Skin Ageing
As skin ages and is exposed to environmental factors such as sunlight, its collagen content gradually decreases. This can contribute to changes in skin structure, including reduced flexibility and increased dryness and the appearance of wrinkles.
Collagen in Cosmetic Products
Animal-derived collagen and plant-derived pseudo-collagen ingredients can bind substantial amounts of water. For this reason, collagen-derived and collagen-like ingredients are used in cosmetic formulations for their conditioning, hydrating and skin-smoothing properties.
They are particularly common in skincare products formulated to improve the appearance and feel of mature or dry skin.
