What is hyaluronic acid?

Hyaluronic acid (trade name Restylane) is a natural tissue component that has gained popularity in recent years as an injectable product that restores facial volume and treats deep wrinkles. It is a completely safe product that has other applications in medicine in addition to its cosmetic effects; it is used in cataract surgery and in some cases of arthrosis as a joint lubricant.

Treatment of bags under the eyes with hyaluronic acid

The treatment of bags under the eyes with hyaluronic acid has become an increasingly popular treatment for patients in their twenties, thirties and forties. At these ages, it is common to have dark circles or grooves under the eyes. When these are prominent sand there are no eyelid bags associated, there are no surgical treatments that can resolve it, since the primary problem is the loss of volume. However, when the groove appears along with fatty bags, we can redistribute this fatty tissue in order to eliminate the grooves.
Hyaluronic acid is a great option for treating bags undergrooves and dark circlesunder the the eyes. It is injected deep under the skin and muscle to avoid visible nodules and achieve a uniform result. Hyaluronic acid treatment is performed during the appointment using topical anesthetic (cream) and the effect is immediate. Slight bruising can sometimes occur in the area. The patient can resume his or her normal activities that same day.

Hyaluronic acid is a temporary and reversible treatment

The body slowly absorbs the hyaluronic acid, but it can be re-injected over time if judged necessary. It is essential for the treatment to not be permanent, since the patient’s anatomical features will change over time and another type of treatment may become necessary.
Hyaluronic acid treatment is reversible. This means that if the patient is not happy with the result, a substance that dissolves the hyaluronic acid in a matter of hours can be applied, returning the area to its initial state.

Other applications of hyaluronic acid

Hyaluronic acid is also used in the treatment of established lines in the skin, not dynamic lines (botulinum toxin is used for the latter). It can be used on the space between the eyebrows, crow’s feet, the jaw area, etc. It is sometimes used in combination with botulinum toxin; for example, on deep wrinkles between the eyebrows that cannot be improved with botox alone.

Other filler substances: Radiesse


For deep folds such as the nasojugal groove or marionette lines, or for enlarging the cheekbones, we do not use hyaluronic acid; instead, we use another product called calcium hydroxylapatite (trade name Radiesse). This product is much more consistent than hyaluronic acid, so it cannot be used for treating surface wrinkles. It is ideal for deep folds and for increasing cheekbone volume, since it is injected into deeper areas and lasts much longer than hyaluronic acid. Additionally, this product promotes collagen formation in the injected area; therefore, once the product has been absorbed, some of its effects will persist.
