The Low Down On Dermal & Lip Fillers

To explain how dermal fillers and lip fillers work, we have the explanation of an expert, Dr. Frank Rosengaus, author of the book “The Rosengaus Method”, a beauty book that breaks the mold and explains the technology used today to fill in facial wrinkles, as well as its risks and recommendations.

In his book, Dr. Frank Rosengaus explains that “fillers or tissue fillings are used to ‘fill in’ wrinkles or expression lines, replace facial volume loss, correct other skin irregularities, and improve the symmetry of the face.”

To better understand the functioning of the substances that are introduced into the skin to fill hollows, we contacted the author. He told us that the first filler approved in 1982 by the US Food and Drug Administration (FDA) was bovine collagen, which was used to fill the folds that go from the nose to the corners of the mouth (also known as marionette lines).

The second US FDA-approved filler was hyaluronic acid in 1996. It is a natural sugar that we produce and destroy in large quantities in our bodies. Hyaluronic acid has a safety record as a filler of 20 years, during which time it has been the subject of a large number of clinical studies.

According to the doctor, hyaluronic acid represents the substance used in more than 85% of filler applications. This filler has the advantage that there are ways to reverse the treatment, so if the patient does not like the effect, she can undo it with the help of enzymes. However, its use in pregnant women is not advised: “hyaluronic acid is the most commonly used substance as a filler thanks to its natural characteristics, but as a universal precaution it’s not suitable for pregnant women,” said the specialist.

Our dermis naturally produces hyaluronic acid, which reduces with age. To recover the lost volume of the face, to hydrate and ‘refill’ wrinkles the acid is applied by microcannulas in the dermis. In very few cases, it can cause the appearance of a small bruise at the spot it is injected, but it is not very common for this to occur. The filling effect lasts from 6 to 18 months, depending on the degradation capacity of each person, as well as the density of the product.

“Non-invasive procedures can be classified within their temporality: fillings of short duration, medium duration, and permanent.” The doctor states that it is better to choose those that are not permanent and that are reabsorbed, as a permanent product can cause problems without any workable solution.

But what about fillers that have a ‘bad reputation’? According to Dr. Rosengaus, “the risks are not from hyaluronic acid; In some cases with dire results, it is later discovered that unapproved fillers were used, or legal but permanent fillers or plastic derivatives.

Hyaluronic acid has been used for a long time, and there are clinical studies that prove its safety. However, the application must be carried out correctly. “As a surgeon, I know knowledge of anatomy is essential. In conferences, I explain to new doctors they not only have to learn what, but also how.

Medically speaking, according to the doctor, there is a simple formula: from the middle of the face to the bottom is where fillers are optimally applied, and from mid-face up, botulinum toxin (or Botox) should be used.
