Hyaluronic acid? A kit or a hit?
Table of Contents
1. What is hyaluronic acid?
A5 Hyaluronic acid is a type of carbohydrate belonging to the group of glycosaminoglycans. This compound occurs naturally in the human body in the form of sodium hyaluronate, i.e. sodium salt.2. Hyaluronic acid for joints
Hyaluronic acid is one of the main constituents of joint fluid. Due to its ability to bind water molecules together, it affects the elasticity and resilience of the joint. This allows the joint to move fluidly without any associated stimuli. It also conditions the resiliency of the cartilage of the joints, which affects proper shock absorption during loading physical activity. Supplementation is found in orthopedics, rheumatology or dentistry.3. Use of hyaluronic acid in cosmetics
A single molecule of sodium salt can bind up to 250 water molecules. A decrease in the level of hyaluronic acid in the skin leads to the destruction of collagen fibers. This in turn results in reduced skin elasticity and stiffness, excessive dryness, and swelling leading to wrinkles. Glycosaminoglycan is a very popular ingredient in many rejuvenating cosmetics.4. Other uses
In addition to the above areas of medicine, sodium salt can be used in other cases. An example of this can be ophthalmology. The aforementioned water-binding ability is often used in the production of eye drops or lens fluid. It is thanks to this that our vision camera is protected from drying out, irritation and penetration of harmful substances. It has a very beneficial effect on the structure of the tear film.5. Opinion of the European Parliament and of the Council
In a study of 20 women aged 19 to 28 years and with a mixed skin type, the effectiveness of sodium salt as an active ingredient in cosmetic preparations was attempted. The skin condition was assessed by measuring moisture levels, skin thickness and transdermal water loss (TWL). The results confirmed the efficacy of reducing TEWL by producing a hydrophilic layer on the surface of the skin.
