Articles
What we explain
in consultation.
Each article answers a real question from someone arriving at the clinic — including the cases where we advise against the procedure. Written by RUV, clinically reviewed by Dr. Najla Vicentini Toledo.
Botulinum toxin: what it is and why people call it Botox
Botox is a brand, botulinum toxin is the substance. What it is, how it acts on muscle, what it treats beyond aesthetics, and what the dose actually determines.
Read article ↗How long Botox lasts: duration by area
Botulinum toxin lasts three to six months, but the timeline shifts with the area treated and the strength of the muscle. What makes it last longer, and why chasing that is the wrong goal.
Read article ↗Sculptra: what poly-L-lactic acid is and how it works
Sculptra is a brand name; the active is poly-L-lactic acid. It does not fill — it stimulates collagen. Why the result takes time, how many sessions, and when we advise against it.
Read article ↗Before you start
- What facial balancing is (and what it isn't)Facial balancing isn't about transforming the face — it's about restoring balance to what is already there. What it does, how long it lasts, the risks, and how the face looks afterwards.7 min
- How much facial harmonization costs: what makes up the priceThere is no honest price list in facial harmonization. What makes up the cost, why the per-ml math misleads, and which low-price signals are a risk.7 min
- How long facial harmonization lastsDuration shifts with the area treated, not just the product. The ranges by area, what speeds up reabsorption, and why the result declines before it ends.6 min
- What a facial harmonization consultation at RUV looks likeWhat happens in a proper assessment, how long it takes, what to bring, and why a first consultation rarely ends with a procedure.5 min
- Natural-looking facial balancing: how to spot who does itA natural result is not less product — it is the right diagnosis. The signs of a serious plan, the questions to ask, and what gives away a bad proposal.6 min
- Full face: when treating the whole face makes senseFull face is not doing everything at once. It is a plan with a sequence and intervals. When it is justified, what it costs in time, and when it is just a package.5 min
- Male facial balancing: what changes in the techniqueThe male face calls for the opposite vectors to the female one. Applying the wrong protocol is the main error in treating men. What changes, and which areas are treated.6 min
- The aesthetic medical history: why it's long and what to discloseThe intake form before a procedure is not paperwork. What each question is looking for, what people most often leave out, and why leaving it out changes the risk.5 min
Botulinum toxin
- Botulinum toxin: what it is and why people call it BotoxBotox is a brand, botulinum toxin is the substance. What it is, how it acts on muscle, what it treats beyond aesthetics, and what the dose actually determines.6 min
- How long Botox lasts: duration by areaBotulinum toxin lasts three to six months, but the timeline shifts with the area treated and the strength of the muscle. What makes it last longer, and why chasing that is the wrong goal.6 min
- Glabella: why the frown line is the most delicate areaThe glabella responds very well to botulinum toxin and carries the highest vascular risk in the face for filler. Understand the difference and why it matters so much.6 min
- Botox in the forehead: why the brow can dropThe forehead is the only muscle that lifts the brow. Relaxing it without balancing the depressors drops the eye — the most common unwanted effect in the upper third.5 min
- Masseter Botox: it treats bruxism, it doesn't cure itToxin in the masseter reduces clenching force and relieves pain. But it doesn't treat the cause of bruxism — and ignoring that is the most common mistake with this procedure.5 min
- Botox for crow's feet: lines around the eyesThe lines at the corner of the eyes are the first to appear and sit in the most delicate area of the upper face. What toxin solves, where the limit is, and when we advise against it.5 min
- Gummy smile: when toxin solves it and when it doesn'tA gummy smile has four different causes, and toxin only treats one of them. How to identify yours before treating — and why the diagnosis is a dental one.4 min
- The frozen look from Botox: why it happens and how to avoid itA frozen face is not a side effect of botulinum toxin — it is the consequence of dose and injection points. What causes it, how it is corrected, and what to ask for at your consultation.5 min
- How many units of Botox: why there is no fixed numberThe dose depends on muscle strength, sex and the goal — not on a chart. What a unit actually measures, and why units are not comparable between brands.4 min
- Does Botox hurt? The pain by area and what helpsBotox injections hurt very little, but not equally in every area. Where it stings most, what actually helps, and what to expect in the hours after.5 min
- Botox aftercare: what actually mattersNot every post-Botox instruction rests on the same evidence. What genuinely lowers risk in the first hours, what is prudent convention, and what is myth.4 min
- Botox didn't work: the most likely causesBefore concluding that there is toxin resistance, there are far more common explanations. How to tell an inadequate dose from antibodies, and what to do.4 min
- Botox during pregnancy: why the answer is to waitNo studies establish the safety of toxin or fillers during pregnancy and breastfeeding. What that means, and what to do if you were treated before you knew.4 min
- Preventative Botox: when it makes sense and when it doesn'tTreating before the wrinkle appears prevents nothing. What toxin actually prevents, in whom, and why starting too early is a cost without a benefit.4 min
- Bruxism and the face: when clenching changes your jawlineBruxism enlarges the masseter and widens the lower third. How to recognise that a change in the face has a functional cause, and why treating only the aesthetics fails.5 min
- Expression lines: dynamic, static, and what changesA line that only shows when you move and a line etched at rest call for different treatments. How to tell which one you have, and why the order of treatment matters.5 min
Fillers
- Hyaluronic acid: the one in the cream is not the one in the syringeThe hyaluronic acid in your serum and the one in filler share a name and do different jobs. What each one does, what neither does, and how to choose.5 min
- Types of facial filler: why they are not all the sameCross-linking, cohesivity and lift capacity define where each filler works. Why the right product matters less than the right place.5 min
- Tear trough filler: only one kind of dark circle respondsThere are three kinds of dark circles, and filler only treats one of them. How to identify yours, why this is the highest-risk area of the face, and when we advise against it.6 min
- Nasolabial folds: filling the crease almost never solves itNasolabial folds are rarely a local problem. Why filling the crease directly usually makes the result worse, what the evidence shows, and when not to do it.9 min
- Natural lip filler: proportion before volumeA natural lip is not a lip with less product — it is a lip whose proportions were respected. What sets the limit, how far 1 ml goes, and why overdone lips start with the touch-up.6 min
- Cheek filler: the base that supports the faceThe midface is structure, not volume. Why treating the cheek improves the nasolabial fold and the under-eye hollow, and why too much in this area ages you instead of the opposite.6 min
- Chin filler: what it changes across the whole profileThe chin is the piece that balances the lower third and the profile. Why it changes how the nose and neck are perceived, how long it lasts, and when the right answer is surgery.5 min
- Jawline filler: definition and what it takesDefining the jawline calls for a high-support product placed deep on bone, and an honest assessment of laxity. When it works and when it makes things worse.5 min
- Facial filler: what happens when it wears offDoes filler stretch the skin? Does the face end up worse once the product is gone? What actually happens to the tissue after filler is reabsorbed.5 min
- Filler swelling: what's normal and what isn'tThe swelling timeline by area, what actually reduces it, and how to tell expected swelling from a warning sign. Why nothing should be judged before day fifteen.4 min
- Lip filler migration: causes and correctionThe whitish ridge above the lip has known causes: the wrong product, a plane that's too superficial, and accumulation. How to spot it, correct it, and avoid it.6 min
- The risks of facial filler: the honest listFrom the common and transient to the rare and serious, with the likelihood of each and what actually reduces risk. No minimising, no alarm.4 min
- Hyaluronidase: how a filler is dissolvedThe enzyme that dissolves hyaluronic acid is what makes filler reversible. When it is indicated, what to expect, the risks, and why it is not a trivial decision.5 min
- Cannula or needle for filler: what changesA cannula has a blunt tip and pushes past vessels; a needle is more precise. The choice is about safety and area — and it is worth asking which will be used, and why.4 min
- Botox or filler: which one is your caseToxin treats movement, filler treats volume. A simple mirror test tells you which one you need — and why so many people ask for the wrong procedure.5 min
- Fillers and Anvisa: how to verify the productHow to check that a filler or toxin has an active registration, what to ask before treatment, and why a product with no traceable origin is a real risk.4 min
Collagen biostimulators
- Collagen biostimulator: what it is and what to expectA biostimulator doesn't fill: it makes your body produce collagen. Why the result takes months, which types exist, the real risks and when we advise against it.5 min
- Sculptra: what poly-L-lactic acid is and how it worksSculptra is a brand name; the active is poly-L-lactic acid. It does not fill — it stimulates collagen. Why the result takes time, how many sessions, and when we advise against it.5 min
- Radiesse: what calcium hydroxylapatite is and what it doesRadiesse is a brand; the active is calcium hydroxylapatite. It fills and stimulates collagen at the same time — and that is exactly why its indication is narrower.5 min
- Biostimulator or filler: how to decideOne restores volume immediately, the other gets the body producing collagen over months. One is reversible, the other is not. How the choice is made — and why it isn't either/or.5 min
- Biostimulator and Botox together: sequence and spacingThe two belong in the same plan, but not on the same day and not in any order. What you gain by separating them, and the intervals that matter.4 min
- Collagen biostimulators at 30, 40 and 50The same treatment delivers differently depending on age, because the ability to produce collagen changes. What to expect in each decade, and when it stops being enough.4 min
- Biostimulator: how long until results showThe week-by-week timeline, including the phase where it looks like nothing happened. Why assessing too early is the biggest source of regret.5 min
- Does a biostimulator hurt? What to expect during and afterDiscomfort during, tenderness for days, and swelling that misleads. What's normal after a collagen biostimulator, what's a warning sign, and what not to do afterward.5 min
- Biostimulator nodules: why they appear and what to doA nodule after a biostimulator has known causes and clear prevention. How to tell a passing lump from one that needs assessment, and why there is no antidote.5 min
- Collagen in the skin: what a supplement does and doesn't doType I and type III collagen hold the skin up, and both decline with age. What the capsule actually delivers, what genuinely stimulates production, and where the overclaiming starts.5 min
Skin quality
- Enlarged pores: what closes them, what softens them, what doesn't changeA pore doesn't open or close — it has a size and an appearance. What actually changes skin texture, in what order, and where injectables fit in.5 min
- Skin boosters: deep hydration, not volumeA skin booster is non-crosslinked hyaluronic acid — it hydrates the skin from within without adding volume. What actually changes, how many sessions, and where it doesn't help.5 min
- Facial laser: what it treats and what it doesn'tLaser is not one procedure — it is a set of device families with different targets. What each type treats, the real downtime, and when the right answer is something else.5 min
- Facial radiofrequency: real results and real limitsRadiofrequency heats the dermis to stimulate collagen. It is comfortable, requires a course of sessions, and delivers modest firming. Where it helps and where it doesn't.4 min
- Microfocused ultrasound: what it does and what it doesn'tMicrofocused ultrasound delivers heat at depth and stimulates collagen. Results take months, it hurts during, and it does not replace surgery. What to expect.5 min
- Photoaging: the damage you choose, or don'tMost of the visible aging of the skin comes from the sun, not from age. What UV does in the dermis, what is reversible and what is not — and what actually changes the outcome.5 min
- Skin in menopause: years of loss compressed into a fewThe drop in estrogen compresses into a short window a loss of collagen that would otherwise take decades. What changes in the skin, what works, and what makes no real difference.5 min
- Facial sagging: what works without surgeryAn honest comparison of the non-surgical options for facial sagging — biostimulators, ultrasound, radiofrequency and threads — with what each one delivers and where the limit is.5 min
- Non-needle facial treatment or injectable: how to chooseDevices treat the skin; injectables treat shape and movement. How to decide where to start, how to combine the two in one plan, and which intervals to respect.4 min
How the face ages
- Facial aging: the four layers that changeThe face ages from the inside out — bone, fat, muscle and skin. Understanding the order explains why treating only the skin delivers so little.5 min
- How skin ages in men and womenMale skin is thicker and ages in a more linear way; female skin changes at different rates across life. What that changes about treatment.5 min
- Facial fat compartments and why they descendFacial fat is divided into compartments that behave differently. Knowing which ones empty and which ones slide down explains the folds and guides treatment.5 min
- Facial sagging: why the skin is not to blameFacial sagging comes from bone, fat and ligaments, not just skin. Understanding where it starts explains why creams do so little, and what actually works.5 min
- Facial volume loss or sagging: how to tell them apartThe two look the same in the mirror and call for opposite treatments. One simple test separates the cases, and getting this distinction wrong is the most expensive mistake in facial aesthetics.5 min
- The golden ratio of the face: why it isn't the goalThe golden ratio has become a sales argument in facial aesthetics. What the evidence supports, what is myth, and why chasing the number produces a generic face.5 min
- Facial proportion: how to read a face in thirdsDividing the face into thirds is the basic tool of facial diagnosis. What each third reveals, what changes with age, and why there is no ideal measurement.5 min
- Facial asymmetry: when it is normal and when to treat itEvery face is asymmetric, and much of that is identity. What separates ordinary asymmetry from asymmetry that calls for assessment — including medical assessment.4 min
Safety and what goes wrong
- Who can inject Botox in Brazil: what the law allowsPhysicians, dentists, biomedical scientists and nurses can inject botulinum toxin within the scope set by each professional council. Estheticians cannot. Here is why.6 min
- Who should not get facial harmonization: contraindicationsAbsolute contraindications, relative ones, and situations where the procedure should be postponed. What to disclose at the consultation, and what to avoid before and after.6 min
- Warning signs after facial fillerWhat is an expected reaction and what needs an immediate call. The signs of vascular occlusion, the timeline that matters, and why waiting for your follow-up appointment can cost you.5 min
- Bad facial harmonization: what can be fixedA result you don't like has different paths depending on the product used. What is reversible, what takes time, and why rushing makes the correction worse.5 min
- Why the same procedure gives different resultsSame technique, same product, same amount — different outcomes. What explains the variation, and why copying someone else's result doesn't work.4 min
- Informed consent: what you are signingThe form does not exist to protect the clinic. It exists so you can decide knowing. What it should contain, what it does not cover, and what to do if nobody explained it.5 min
