Hyaluronic acid

Hyaluronic acid is available in various forms, each tailored to specific needs.

• It can be found in dietary supplements, which are taken orally (capsules or powder) to support skin, joint and eye health. Manufacturers - Zenyth, Swedish Nutra, Secom, etc.
• Hyaluronic acid is also found in creams and serums for topical application, where it moisturises and improves the appearance of the skin.
• Another commonly used form is injectable hyaluronic acid, used in facial aesthetics to fill wrinkles or add volume to the lips.

Hyaluronic acid is indicated not only in cosmetics but also in medicine. In the aesthetic field, it helps reduce wrinkles and fine lines, giving the skin a more youthful appearance. Various minimally invasive procedures can also be performed, such as rhinoplasty with hyaluronic acid or hyaluronic acid injections into the lips.

Hyaluronic acid-based medicines are used to treat joints, such as in cases of osteoarthritis, where they help lubricate the joints, reducing pain and increasing mobility. It is also used in treatments for dry eyes.

The dosage of hyaluronic acid varies depending on the form of use.

For oral supplements, the recommended dose is usually 50-200 mg per day, but it is essential to consult a doctor to determine the appropriate dose.

Creams and serums are usually applied once or twice a day, depending on the needs of the skin.

The use of hyaluronic acid on skin with open wounds or active dermatological conditions is not recommended without medical advice.

The use of hyaluronic acid during pregnancy or breastfeeding should be avoided unless a doctor has been consulted.

It is essential that users choose products specifically designed for their skin type.

For example, people with extremely dry skin will benefit more from creams rich in hyaluronic acid, while those with oilier skin may prefer lighter serums that do not block pores.

In general, hyaluronic acid is well tolerated by most users, but side effects may occur.

The most common are local allergic reactions, such as redness, itching or skin irritation, especially in people with increased sensitivity.

In the case of injections, temporary swelling, pain at the injection site or the formation of subcutaneous nodules may occur.

Hyaluronic acid does not usually interact significantly with other medicines.

However, it is recommended that people undergoing treatment with anticoagulants or other medicines that may increase the risk of bleeding discuss this with their doctor before using injectable hyaluronic acid.

Overdose of hyaluronic acid is rare, given its bioactive nature and how the body metabolises it. However, excessive use of topical hyaluronic acid products may cause skin irritation and other adverse reactions.

It is important to follow the recommended doses and consult a doctor if any unpleasant symptoms occur.

It is essential that products are stored in a cool place, away from direct light and moisture, and out of the reach of children.

Checking the expiry date is also important to avoid using damaged products.
