Deciem hyaluronic acid: what patients should know

Hyaluronic acid binds water and is commonly included in serums and moisturisers. Applied to the skin, it can reduce the feeling of dryness and leave the surface feeling more comfortable. The product is not designed to enter a joint, repair cartilage, or treat a tendon, bone, or muscle problem.

Formulas differ, so read the ingredient list rather than relying on the product name alone. Sensitive skin may react to supporting ingredients such as fragrance or preservatives. A topical product also cannot explain or treat new joint swelling, restricted movement, or deep pain.

Use the amount and frequency shown on the packaging, usually on clean skin. Avoid broken or infected skin and contact with the eyes. If you are introducing several products, add one at a time so an irritating ingredient is easier to identify. Stop if you develop persistent redness, itching, burning, swelling, or blistering.

For a plain explanation of the ingredient, visit [Hyaluronic Acid](/materials/hyaluronic-acid/). If you were offered treatment for joint symptoms, [Hyaluronic Acid Injection](/treatments/non-surgical-orthopedics/hyaluronic-acid-injection/) describes a different medical use.

Seek emergency help for trouble breathing, throat or facial swelling, faintness, or widespread hives after use. Contact a clinician for a painful or spreading rash, pus, fever, or symptoms that do not improve after stopping the product. Seek orthopaedic advice for persistent joint pain, swelling, locking, or loss of function instead of treating those symptoms with skincare.

Ask whether the formulation is suitable for your skin, whether it may interact with a prescribed topical treatment, and what to apply if irritation occurs. If an injection has been proposed, ask its purpose, expected effects, alternatives, and aftercare.
