What is hyaluronic acid?

Hyaluronic acid (HA) is a polysaccharide ( sugar ) of natural formation and viscous texture found in the various tissues of our body. The largest amount of hyaluronic acid resides in the skin tissue, about 7-8 grams per adult, which represents about 50% of the total that a human being has.

With the passage of time, the presence of this substance decreases markedly. Along with other reasons, this causes aging of the skin and, with it, appearance of wrinkles , sagging or loss of firmness.


One of the main properties of hyaluronic acid is its great ability to attract and retain water. For this reason, its use in Medical-Aesthetic treatments allows deep rehydration of the epidermis and dermis of the treated area so that its appearance is smoother. It also increases its thickness and volume, which decreases the furrows of the skin.


Hyaluronic acid can be of animal or bacterial origin, although in essence it is always the same. Regarding its safety, its use is well documented in the fields of ophthalmological and orthopedic surgery. Over the past two decades, more than 30 million patients have been treated with products derived from this compound.

What aesthetic uses do you have?

The use of hyaluronic acid in Aesthetic Medicine has been known since 1996. Its most important characteristic as a dermal filler is the capacity it has to retain liquid, that is, to attract water. This holding capacity is thousands of times its weight.


When we age our skin cells progressively lose their production capacity. The amount of hyaluronic acid is reduced and its molecular weight decreases, so that it no longer conserves water as it did previously. Therefore, the tissues thin with the passage of time and this volume reduction gives rise to wrinkles.


What is the purpose of a facial filler?

The main function of hyaluronic acid as an implant is to fill and give volume to the skin. In addition to eliminating wrinkles and folds, it stimulates the natural production of collagen .


What kind of defects can you correct?

The use of hyaluronic acid allows to increase the volume of lips and cheekbones, the filling of nasogeneano grooves, correct peribucal wrinkles, dark circles , labial commissures and frown.


How is the facial filling technique performed with hyaluronic acid?

Depending on the area to be treated, hyaluronic acid will be injected into the dermis, just under the skin where the wrinkle is, or above the bone (supraperiosteal) as in the case of filling the cheekbones.


Hyaluronic acid is a substance compatible with all tissues, therefore does not require skin tests as occurs with collagen. It is not necessary to perform any allergy test, because the product is integrated naturally without causing fibrosis due to foreign body reaction and, therefore, does not alter the characteristics of the skin.


Does it cause some kind of discomfort?

Prior to the application of the product, we use a little topical or injected local anesthesia to minimize the patient's discomfort.


Are the results obtained definitive?

The results are not definitive. They last about a year, sometimes longer, depending on the brand and the density of the product.
