Hyaluronic acid — Uses, Dosage, Side Effects & Safety

Drug class: Viscosupplement, Ophthalmic Agent, Dermal Filler

Overview

Hyaluronic acid is a naturally occurring substance found in the human body, especially in joints, eyes, and skin. As a medication, it is used to treat osteoarthritis pain by injecting it directly into the affected joint, most commonly the knee. It is also used in ophthalmology as a lubricant during eye surgeries and as an ingredient in artificial tears for dry eyes. In dermatology, hyaluronic acid is used as a dermal filler to reduce wrinkles and add volume to the skin. Hyaluronic acid works by acting as a lubricant and shock absorber in the joints, helping them move smoothly and reducing pain. In the eyes, it helps maintain moisture and protects delicate tissues. When used on the skin, it attracts and retains water, improving hydration and elasticity. Key points for patients: Hyaluronic acid is generally well-tolerated and can provide relief from joint pain, dryness, or skin aging. It is usually administered by a healthcare professional. Let your doctor know about any allergies or medical conditions before starting treatment.
