It’s Sunday night, and you finally decide to look into it.
You type “hyaluronic acid” in your browser, a drugstore serum comes up, then some capsules, then a syringe with five stars.
All three say the same thing on the label. None of them looks anything like the others.
What is hyaluronic acid?
Hyaluronic acid is a polysaccharide that occurs naturally in our bodies and has an extraordinary ability to attract and hold water. In the skin, it contributes to hydration, volume, and the tissue’s viscoelastic properties.
When we talk about a filler, we’re talking about a different medical product: the hyaluronic acid has been formulated and, in most cases, cross-linked so it resists the body’s natural breakdown for longer and holds its shape and volume.
With all those wonderful functions, what is hyaluronic acid actually for?
First and foremost, hyaluronic acid isn’t only for filling wrinkles.
Depending on the formulation and the area, it can be used to add or restore volume, soften certain folds, define contours, and balance proportions.
Among the most popular treatment areas are the lips, cheeks, chin, jawline, nasolabial folds, under-eye hollows, and the backs of the hands. Specific indications depend on each product and on each country’s regulations.
That’s why there’s no universal hyaluronic acid for everything.
A filler designed to project the chin doesn’t necessarily share the properties of one meant to blend into the lips. Concentration, degree of cross-linking, and gel properties vary from product to product.
Which form of hyaluronic acid is right for me?
Now that you know exactly what it’s for and how it works inside and outside your body, the next step is to figure out what results you’re looking for and what you feel your face needs at this stage of your life.
Your answer points to the form that suits you best. So, what’s the first word that comes to mind when you ask yourself that question?
If the word is:
Rejuvenation, your answer is definitely an injectable: by far, the option with the most visible and measurable effect. It lasts roughly 6 to 18 months, depending on the area and the product.
Hydration and glow, your answer is a serum, which hydrates the surface. It works as a humectant: it draws water into the outermost layer of the skin, so skin looks plumper and fine lines caused by dehydration soften. The effect is real, but temporary and superficial. High-molecular-weight molecules don’t penetrate, and low-molecular-weight ones go a little deeper, but none reaches the dermis in any meaningful way. It’s a good routine staple, affordable and low-risk, but it doesn’t fill or restructure anything.
Routine support, then capsules are your best option.
What brands are out there?
Among the best-known international brands are JUVÉDERM®, Restylane®, BELOTERO®, and TEOSYAL®. Their portfolios include different formulations, and not all of their products share the same indications.
The important question isn’t “What’s the best brand?”
It’s: What’s the right product for my face and for what I want to achieve?
How much does it cost?
There’s no single price for hyaluronic acid. It depends on the brand, the formulation, the amount used, the area, and the medical work involved.
For reference, published prices for this service in Mexico City currently range from roughly MXN $5,500 to $8,500, although some treatments can go beyond that range.
What really matters is being aware of what you’re investing in when you choose a particular clinic or brand.
You’re investing in the product, where it comes from, the anatomical knowledge of the person injecting it, their technique, and their ability to respond to a complication.
In 2022, for example, COFEPRIS (Mexico’s federal health regulator) issued an alert about Juvéderm Ultra 4: it had no registration in Mexico, and a counterfeit batch was in circulation. The product was being sold mainly through social media, at “unbeatable prices.”
Today you can check any product in COFEPRIS’s online registry of medical devices (Visor de Registros Sanitarios de Dispositivos Médicos).
Can the effect be reversed if I don’t like the result or it’s overdone?
One of hyaluronic acid’s greatest advantages is an enzyme called hyaluronidase, which can dissolve the filler quickly.
That’s key in the event of a rare but serious complication: the product blocking a blood vessel. But each gel responds differently to the enzyme.
That’s why where you go, and the quality of the products you choose, matter so much.
Before your appointment, ask
What product are you going to use on me, and why? Can I see the box, the batch number, and the expiration date? Who will be injecting it? Do you keep hyaluronidase at the clinic?
A serious clinic answers without getting uncomfortable.
In the end, hyaluronic acid isn’t the star.
It’s a tool.
And like any medical tool, its value lies not only in what it can do, but in knowing when, where, and how much to use it.
Because not every face needs more volume. Not every wrinkle needs to disappear. Not everyone needs a filler.
And that’s where aesthetic medicine stops chasing an image.
It becomes about understanding your face, respecting its history, and making decisions that help you feel like yourself.
