Drinking collagen – the effect of collagen on skin, hair and nails

Is your skin dry and not very elastic? Wrinkles appear? Hair falls out excessively? And the nails are brittle and brittle? These could be signs of a collagen deficiency. Collagen is a very important structural element of our skin and plays a large role in the healthy appearance of hair and nails. Due to its biological properties, collagen is widely used in cosmetics and aesthetic medicine, and in the form of supplements.

Collagen and skin

Collagen it is an essential component of the extracellular matrix and is a key protein in the skin. It acts as a scaffold stabilizing the structure of the dermis. It ensures the continuity of cellular renewal processes in the skin and helps to maintain the proper level of its hydration. As a result, our skin looks nice and is characterized by good condition, elasticity, elasticity and durability. However, with age, the rate of collagen synthesis in the skin decreases, its solubility decreases and the collagen fibers become thinner. Reduced collagen production and increased collagen degradation may result in poorer wound healing and skin loss in the elderly. Additionally, the lower amount of collagen makes the skin less resistant to mechanical factors. Collagen deficiency weakens the facial muscles, which promotes the appearance of wrinkles.

One of the ways to counteract these phenomena is to supplement collagen resources with good-quality supplements. Collagen hydrolysates may affect the production of endogenous collagen and reduce the activity of enzymes responsible for its degradation, which may have a positive effect on delaying the effects of skin aging and reducing wrinkles. Hydrolysed collagen improves the appearance of the skin, moisturizes it, and delays the aging process of the skin. Due to the ability to bind water, it provides adequate skin hydration. There has even been a study in which women aged 35-55 years were given collagen daily for 8 weeks. Thanks to this collagen supplementation, the elasticity and moisture of the skin has improved. Collagen can also reduce cellulite and stretch marks. When the skin becomes thinner and less elastic as a result of the decline in the level of collagen in the body, its supplementation may improve skin tone, making the dimples less visible. Collagen may also help to heal wounds faster, soothe scars, and help heal burns.

Collagen for nails

Collagen protein is the building block of nails, hair and teeth. Collagen affects the hardness of the nail plate, therefore, in the case of its deficiency, nails often become weaker, break and split.

Collagen for hair

Collagen provides essential amino acids that nourish the hair follicles, contribute to their proper growth and reconstruction. Collagen deficiency often manifests as thin, dry and brittle hair. They also start to fall out excessively, which can lead to premature baldness. Collagen supplementation affects the regeneration of damaged hair.

Collagen and aging processes

The human body after the age of 25 is not able to ensure the balance between the processes of collagen production and degradation in tissues and organs. When the process of decomposition of proteins and collagen fibers outweighs its production, it is worth considering supplying collagen from the outside. In addition, the reduction of endogenous collagen synthesis (collagen that we produce ourselves) is not typical only for the elderly, for mature age. A decrease in collagen levels may also appear in young people, which is influenced by genetic conditions and hormonal disorders. The faster degradation of collagen is also influenced by excessive and chronic stress, various diseases, too intense physical effort, toxins and weather conditions, including temperature. Overexposure to the sun accelerates the breakdown of collagen fibers. That is why it is worth protecting the skin against excessive ultraviolet radiation with good quality creams with special UVA and UVB filters.

Diet and collagen supplementation

An important role in the synthesis of natural collagen is played by a properly balanced diet, which should be rich in vitamins A, C and E. These vitamins are antioxidants that promote proper collagen synthesis. For this reason, when using collagen-containing preparations, it is also worth remembering about the consumption of these vitamins, especially vitamin C, which directly participates in the synthesis of collagen fibers.
