What should you know about Vichy Minéral 89 hyaluronic acid?

The name refers to a skincare formula that includes hyaluronic acid, a substance that can hold water at the skin surface. Applied to the skin, it may help skin feel more comfortable and look less dry. It does not travel through the skin to rebuild cartilage, repair a tendon, or treat arthritis.

This product should be kept separate from hyaluronic acid injections. An injection is delivered by a trained clinician into a specific body area for a selected musculoskeletal problem; a serum or gel is used on the skin.

Use the product only as directed on its packaging, and stop if it causes marked irritation, swelling, or a new rash. Patch testing can be sensible when your skin reacts easily. For joint, muscle, or tendon symptoms, describe the location, duration, triggers, and any weakness to a clinician; skincare cannot replace an assessment or rehabilitation plan.

Arrange medical advice for persistent pain, repeated swelling, loss of movement, numbness, or weakness. Seek urgent care after a significant injury if a limb looks deformed, feels cold, or cannot bear weight. Facial swelling, breathing difficulty, or widespread blistering after a product needs urgent attention.

Ask whether your symptoms come from the skin, a joint, or another structure; whether a topical product has a useful role; and which examination or treatment would address the underlying problem.
