Hyaluronic acid. What is it and how does it work?

Hyaluronic acid is a naturally occurring substance in the body that is widely used in medicine, cosmetics and biotechnology due to its unique properties. Hyaluronic acid plays an essential role in ensuring tissue hydration , elasticity and structural stability. It has the ability to attract and retain large amounts of water – one gram of hyaluronic acid can hold up to six liters of water, making it an indispensable moisturizer.

The benefits of hyaluronic acid for the skin are manifold . First of all, it is an extremely effective moisturizer that helps to maintain skin moisture, elasticity and softness. With age, the natural concentration of hyaluronic acid in the skin decreases, causing the skin to become drier, lose elasticity and develop wrinkles. Using products containing hyaluronic acid can compensate for this loss and maintain the skin's moisture . The moisturizing effect not only gives the skin a healthy and youthful appearance, but also strengthens the skin's barrier function, protecting it from external environmental factors such as pollution and UV rays.

Areas of application of hyaluronic acid

One of the most important fields of application of hyaluronic acid is dermatology and aesthetic medicine . Here, hyaluronic acid is often used as the main ingredient in moisturizing creams, serums, masks and injectable fillers. These products help reduce wrinkles, restore skin elasticity, moisture and overall skin condition . Injectable fillers with hyaluronic acid are used to correct facial contours, increase lip volume, shape cheekbones and smooth wrinkles. Hyaluronic acid is also used in mesotherapy procedures, where it is injected into the skin in small amounts to revitalize and hydrate it.

In orthopedics, hyaluronic acid injections are an important part of osteoarthritis treatment. Hyaluronic acid acts as a natural component of joint fluid that increases viscosity and reduces friction between joint surfaces. It helps reduce pain and improve joint mobility, especially in the knee and hip joints. In addition, these injections can stimulate the regeneration of joint cartilage and slow down degenerative processes.

In ophthalmology, hyaluronic acid is used as a viscoelastic material in eye surgery, especially cataract surgery. It helps maintain the stability of the eye structures during surgery, protects the cornea and ensures proper intraocular pressure. In addition, hyaluronic acid is an important component in eye drops for the treatment of dry eye syndrome. These drops help to hydrate the eyes and reduce the symptoms of dryness and irritation.

In dentistry, hyaluronic acid is used to treat periodontitis and promote tissue regeneration. It can be injected into the gums to reduce inflammation, promote tissue healing and restore lost tissue volume. In addition, hyaluronic acid is used as an ingredient in oral care products such as toothpastes and mouthwashes due to its ability to moisturize and promote tissue regeneration.

Hyaluronic acid is also used as a drug carrier and in biotechnology . In pharmaceuticals, hyaluronic acid is used as a drug carrier, which helps to improve the bioavailability of drugs and prolong their duration of action. It can be incorporated into various drug forms, including injections, gels, and tablets, to ensure better absorption and effectiveness of the active ingredients.

In addition to these main areas, hyaluronic acid is also used in other medical applications, such as wound and ulcer treatment, regenerative medicine, and even as part of some surgical joint and tissue implants. Due to its versatility and ability to interact with various biological processes, hyaluronic acid remains one of the most important and widely used substances in modern medicine .

What are the benefits and effects of hyaluronic acid?

Hyaluronic acid (HA) is a highly valued facial skin care product due to its unique properties and wide range of applications. One of the main properties of hyaluronic acid is the ability to attract and retain a large amount of water - one gram of this substance can hold up to six liters of water. This ability makes hyaluronic acid one of the most effective moisturizing agents that help maintain skin hydration, elasticity and softness. Moisturized skin looks healthier, smoother and younger, and its surface becomes smoother .

Naturally, with age, the concentration of hyaluronic acid in the skin decreases, resulting in drier skin, loss of elasticity and wrinkles. Hyaluronic acid-based products such as serums, creams and injections help compensate for this loss and maintain optimal skin moisture levels . The moisturizing function of hyaluronic acid not only gives the skin a fresh and youthful appearance, but also strengthens the skin's barrier function, protecting it from harmful external factors such as pollution and ultraviolet (UV) rays.

In addition to hydration, hyaluronic acid also plays an important role in cell regeneration and wound healing . It stimulates the activity of fibroblasts, which are responsible for the production of collagen and elastin, the two main structural proteins of the skin. Collagen gives the skin firmness , and elastin - elasticity, so promoting their synthesis helps to keep the skin youthful and firm. Hyaluronic acid also has anti-inflammatory effects that can help reduce skin redness, irritation, and inflammation, making it useful for treating a variety of skin conditions such as acne, eczema, and dermatitis.

Hyaluronic acid is widely used as an injectable filler in aesthetic medicine. These injections help restore skin volume and smoothness, reduce wrinkles and improve facial contours . Hyaluronic acid fillers are particularly effective for increasing lip volume, shaping cheeks, smoothing nasolabial folds and moisturizing facial skin. Since hyaluronic acid is a natural substance of the body , it is well tolerated and rarely causes allergic reactions. Injections with hyaluronic acid provide natural-looking results that can last from several months to years, depending on the product used and the individual characteristics of the patient.

Hyaluronic acid is also used in mesotherapy procedures, where small amounts are injected into the skin in order to revitalize and moisturize it . These treatments help to improve skin structure, smooth out fine lines and give the skin a glow. In addition, hyaluronic acid can be used as part of combined procedures with other substances, such as botulinum toxin injections or laser procedures, to achieve even better results.

In conclusion, hyaluronic acid is an extremely valuable substance for facial skin care due to its moisturizing, regenerating and anti-inflammatory properties . It helps maintain the skin's elasticity, firmness and youth, reduces wrinkles and improves the overall condition of the skin. Using products and procedures containing hyaluronic acid can effectively fight the signs of skin aging, ensure skin moisture and protect it from harmful environmental factors.
