In recent times, the search for a face free from wrinkles and different indicators of getting older has gained a fantastic ally: hyaluronic acid, an ingredient that may be utilized to the internal layers of the pores and skin to hydrate, plump and provides desired contours. pores and skin, chin, cheeks, lips and eyelids.

One of many stars of the favored “facial match,” ingredient has develop into synonymous with a magnificence product and is now featured on the labels of many lotions and in ads for aesthetic clinics or places of work.

However is it obtainable to everybody? Are there contraindications and negative effects? And what’s the distinction between lotions bought in shops and injections given in places of work?

Perceive the primary points with this product in 5 factors.

What’s hyaluronic acid?

Hyaluronic acid is a substance produced by our personal our bodies and lots of different animals.

It has the perform of serving to to help and fill this tissue in addition to sustaining the pure moisture of the cells that make up the internal layers of the pores and skin.

“Over time and the getting older course of, we lose the pores and skin’s extracellular matrix, which turns into thinner and looser,” explains Dr Alessandra Grassi Salles, coordinator of the Aesthetic, Beauty and Laser Surgical procedure Group on the College of São Drugs. Paul (USP).

This “extracellular matrix”, which the professional speaks of, precisely corresponds to all of the substances that “fill” the pores and skin and maintain the pores and skin cells collectively.

Over time and these compounds naturally lower, it’s regular for our physique’s floor layer to sag, wrinkle and ultimately skinny.

That is the place purposes of hyaluronic acid come into play: the aim is to exchange or enhance the quantity of this substance to maintain the pores and skin on the desired thickness.

What’s the distinction between lotions and injections?

“The massive query is whether or not the hyaluronic acid we produce naturally has a really brief half-life. It’s absorbed by the physique in lower than 48 hours,” says Daniel Boro, MD, MD, of the Brazilian Society of Plastic Surgical procedure.

“The trade then developed variations of this substance which can be way more resistant and keep within the physique for months.”

Immediately, hyaluronic acid injected in aesthetic procedures is obtained by the fermentation technique of some microorganisms.

Lotions carry artificial variations of this ingredient.

In the course of the getting older course of, the pores and skin loses a variety of substances that give help and firmness to the floor layer.

Along with manufacturing, the 2 sorts of merchandise introduce elementary variations within the mechanism of motion.

“The primary perform of the cream is to supply very superficial hydration of the pores and skin. Injectables have the position of filling, supporting and rejuvenating components of the face”, summarizes physician Alessandra Ribeiro Romiti, advisor to the Dermatological Cosmetics Division. Brazilian Dermatology Affiliation.

Specialists clarify that the cream introduces giant molecules that can’t transcend the primary layers of the pores and skin. With this, it isn’t potential for the hyaluronic acid, which is a part of the formulation, to go deeper and fill the aforementioned extracellular matrix.

By the way in which, the same hydration impact is noticed in capsules that additionally deliver this element.

Nonetheless, earlier than beginning to use any of those substances, it’s supreme to hunt assist from a specialist.

“If an individual has oily pores and skin and makes use of an excessive amount of cream, there’s a danger that this behavior will clog pores and skin pores and trigger pimples,” explains Salles.

Who’s hyaluronic acid appropriate for?

On the whole, there isn’t a “cake recipe” or common suggestion that matches all.

“We will apply hyaluronic acid as a part of the pores and skin getting older administration course of,” says Boro.

In Romiti’s view, every part will rely on what the affected person is on the lookout for and their particular person traits.

“There isn’t a proper age to start out remedy. There are individuals who begin engaged on darkish circles at age 25, there are people who find themselves attempting to appropriate sure elements of the face after bariatric surgical procedure, or there are individuals who need a extra world strategy after they attain their 50s or 60s,” she says.

Along with the probabilities to change sure elements of the face with new aesthetic applied sciences equivalent to hyaluronic acid, Salles provides that the healthcare skilled should perceive every particular person’s motivations.

“It is a massive mistake to assume that we have now to have a 30-year-old face to be blissful. If we will not work out what is going on on contained in the affected person, his face might even be rejuvenated, however it by no means might be.” actually glad,” he emphasizes.

Are the applying outcomes closing?

Not. The hyaluronic acid used within the procedures lasts even longer, however is slowly absorbed by the physique. “All of it relies on the kind of gel and what a part of the face it is being utilized to,” Boro replies.

“It usually stays within the pores and skin layers for a few 12 months, however that is often between six and 18 months.”

It is value explaining right here that not all hyaluronic acids are the identical: there are extra constant formulations and extra simply malleable formulations.

The skilled selects the suitable kind primarily based on the a part of the face and the specified impact – for instance, a firmer gel could also be required on the chin or chin, whereas on the lips or eyelids it’s higher to use a versatile product. and elastic to permit the mouth or eyes to maneuver extra naturally.

Lotions with hyaluronic acid even assist moisturize the pores and skin, however don’t attain the deeper layers.

Apart from consistency, one other issue that inhibits the length of hyaluronic acid is the motion of facial buildings. It tends to wear down shortly on areas that transfer so much, just like the lips and eyes, and keep on for an additional period of time on areas which can be much less cell just like the chin.

However after all, consultants don’t look ahead to the hyaluronic acid to be utterly depleted to point new purposes.

“We do a periodic follow-up and we have now protocols to make modifications as wanted,” Boro says.

Is there a danger of negative effects after the process?

Opposed occasions can occur, and it’s important for each professionals and sufferers to know tips on how to establish them in order that they will act shortly and comprise the injury.

One of the crucial feared risks arises when the product is injected into the flawed space of ​​the face. With this, hyaluronic acid can linger contained in the blood vessels that irrigate the face, inflicting a blockage within the nostril and lip areas that results in tissue dying and even blindness.

“To reduce this danger, it is vital to have this process executed with professionals who’ve loads of expertise and years of coaching,” says Salles.

“This is not one thing you may study in a weekend course. It takes years of research to grasp all of the anatomical variations of the face and the place the veins and arteries are prone to be. And even essentially the most seasoned specialists could make errors and inject unintentionally.”

To reduce injury, it’s potential to make use of an enzyme referred to as hyaluronidase, which has the perform of absorbing incorrectly utilized hyaluronic acid.

However this “antidote” also can not be utilized in all circumstances: there are sufferers who’re allergic to hyaluronidase and develop extreme reactions.

Along with occlusion of arteries and veins, different potential negative effects are marked inflammatory reactions with redness and swelling, and the formation of nodules on the injection website.

The excellent news is that these issues are often short-term because the product is absorbed by the physique.

Lastly, Salles considers that extreme hyaluronic acid utility – and its undesirable aesthetic penalties – will be seen as a detrimental occasion in some circumstances.

“There are circumstances the place 10 to twenty milliliters of hyaluronic acid are injected and also you see spectacular transformations,” he observes.

“Nonetheless, this may have an effect on the motion of the face and the particular person not has a smile or a pure expression. You should discover a steadiness in order that the particular person feels good and might acknowledge their very own face within the mirror.”
