The best laser for facial rejuvenation

The question arrives ready-made: which one is the best. The honest answer is a little disappointing, because laser is not one thing. It is a family of devices that do different jobs, and the "best" one changes with your skin, your concern and how many days you can live with a red face.

Whoever answers "CO2" is really saying "the most aggressive". Whoever answers "Fotona" is repeating the name that shows up most on Instagram. Neither one is a recommendation. They are shortcuts.

What actually changes the result is understanding three things before choosing: what the laser does to the skin, what you want to fix, and what your skin can tolerate.

How laser works, in an explanation that's actually useful

Every facial laser is a variation on the same move: it delivers energy at a specific depth in the skin, causes a controlled injury, and the body responds by rebuilding that tissue — with new collagen, redistributed pigment, a smoother surface.

The difference between devices lies in how that energy gets past the surface. And that is where the only distinction that really matters comes from.

Ablative and non-ablative — the distinction that matters

• Ablative removes layers from the surface of the skin. CO2 is the classic example. It delivers more result per session, and charges for it in recovery: raw skin for days, redness that lingers for weeks, strict sun care.
• Non-ablative heats the deeper layers and spares the surface. Recovery is fast, discomfort is low, and for that reason it takes more sessions to reach a comparable result.

There is also fractional, which is a delivery method, not a separate category: instead of treating the whole area, the beam is split into microcolumns that leave intact skin between them. The intact skin speeds up healing. Almost every modern laser is fractional.

Translated into the real decision: you are choosing between a concentrated result with a long recovery, or a gradual result with a normal life. There is no third option, and be wary of anyone who offers one.

CO2 laser or Fotona: which is better

These are fundamentally different things compared as if they were direct competitors, and that confusion comes from marketing, not from the clinic.

Fractional CO2 is ablative. It works on skin texture: acne scars, enlarged pores, fine lines, accumulated sun damage. It is the most powerful surface tool available today, and the one that demands the most recovery.

Fotona is a platform that combines different wavelengths in the same device, with mostly non-ablative protocols. It works through heating and stimulation, with a short recovery.

Asking which is better is like asking whether a drill is better than a screwdriver. If the concern is marked texture and you have ten days, CO2 delivers what non-ablative cannot. If the concern is skin quality and you have a normal schedule, the non-ablative route makes more sense.

There is a second point marketing hides: the brand of the device matters less than who operates it. The wrong settings on the best machine in the world produce pigmentation, scarring and a result worse than doing nothing. The right settings on an ordinary device get the job done.

The best laser for enlarged pores

Enlarged pores respond to lasers that work on the surface — fractional ablative, above all. It is the classic CO2 scenario.

It is worth understanding what to expect, because this is where expectations tend to drift. Pore size is largely genetic and does not disappear. What the laser does is reduce how they look: it tightens the rim of the opening, improves the surrounding texture and lessens the shadow that makes a pore look bigger than it is. The skin becomes visibly more even. The pores are still there.

A detail rarely mentioned: oily skin with enlarged pores almost always has a component of mild laxity underneath. Skin that loses support stretches the pore vertically, and it starts to read as larger. In those cases, treating only the surface delivers half the result — and it is one of the reasons the assessment here looks at the whole face before treating the concern the person came in with.

The best laser treatment for sagging skin on the face

This is the question where the answer frustrates the most: sagging is not the best indication for laser.

Laser works on the skin — surface, texture, pigment, superficial and mid-level collagen. Sagging in the midface and lower face is a problem of deeper layers: fat, support, bone structure that has receded. Laser improves the quality of the skin covering that structure, and so the face looks better. But it does not lift what has dropped.

What works at depth with a focus on support is a different family: microfocused ultrasound. At RUV we use Ultherapy, by Merz. It delivers energy at depth without touching the skin's surface, and the transducer chosen defines the action — the shallower ones stimulate collagen; the deeper ones act on fat. We use all of them, according to what each area calls for.

CO2 laser or microfocused ultrasound

The most useful comparison in this article, because it is the one that settles many cases correctly.

An important point for Brazilian skin: microfocused ultrasound does not interact with melanin, because it does not use light. In higher skin types — the majority of the population here — that removes a risk ablative laser carries: dark patches on the treated area after the procedure.

And they are not mutually exclusive. One treats the skin, the other treats what holds the skin up. Many plans include both, at separate times.

The most advanced laser for the face

Newest is not the same as best for you, and that is the trap in the question.

Every year a new technology appears with a strong brand name and a promise of "results with no downtime". Some become established. Most are the same physical principle in different packaging, with heavy marketing investment in the first eighteen months.

What I would look at before "the newest":

• Registration with Anvisa for the intended use. Imported devices without registration do circulate, and the problem shows up when something goes wrong.
• Time in the literature. A technology with ten years of publications has its side effects mapped. A technology with two years has a brochure.
• Whether the protocol was tested on your skin type, and not only on fair European or North American skin.
• Who operates it. I repeat it because it is the most decisive factor and the least discussed.

How much a laser session costs

We don't publish prices on the site, and there is a practical reason: the same procedure name covers jobs of very different sizes.

What actually makes up the cost:

• Area treated. The full face, just the eye area or a single scar are different jobs.
• Depth and aggressiveness of the protocol, which determine time in the room, the anesthesia needed and the follow-up afterward.
• Number of sessions planned. Ablative usually gets there in fewer passes; non-ablative works in a series.
• Follow-up structure. Return visits, adjustments, aftercare guidance — what sustains the result after you leave.

Comparing one loose number against another loose number is the fastest way to choose wrong. What you compare is the plan.

How the assessment decides the laser

The whole face before the complaint. A person arrives asking for "that laser I saw", and the assessment starts somewhere else: what the real concern is, what in the structure of that face produces it, and which tool answers it.

In practice, this conversation decides four things:

• What actually bothers you — texture, pigmentation, pores, skin quality or loss of support. Often it is not what the person named on arrival.
• Skin type, which restricts protocols and is ignored with alarming frequency in a country of mixed-heritage skin.
• The real recovery window the person's life can accommodate. Prescribing ten days of hiding at home to someone who doesn't have ten days is prescribing that they quit halfway.
• History — recent isotretinoin, recurrent cold sores, a tendency toward keloid scarring, previous procedures in the area.

Natural-looking here is a criterion, not a slogan. Treated skin has to keep looking like your skin, with pores, with texture, with movement. Skin that is too smooth gives the procedure away as much as a face with no expression.

Safety

Laser carries real risk, and it is higher in pigmented skin: post-inflammatory hyperpigmentation — the dark patch that appears weeks later on the treated area. It is the most common complication in higher skin types, and the most avoidable, because it depends on the choice of settings and on preparing the skin beforehand.

When the plan combines laser with filler already present in the face, another layer comes in. Doppler ultrasound assessment is part of the process here: before, to understand the structure of that face — including material from previous treatments, which changes the plan; and after, to confirm there is no vessel compression. That is what turns "it's safe" from a promise into a verification.

When we advise against it

• When the main concern is sagging in the midface or lower face. Laser improves skin; it does not lift structure. The path is a different one, and saying so up front avoids a series of sessions that won't deliver what the person wants.
• When the expectation is skin with no pores and no texture. That does not exist, not even with the most powerful device on the market.
• When the recovery window doesn't fit the person's life. An ablative treatment interrupted halfway is the worst of both worlds.
• With recent isotretinoin use, because of its effect on healing.
• With an active lesion in the area — cold sores, infection, ongoing inflammation. Treat that first, do the procedure later.
• Pregnancy and breastfeeding. An elective procedure waits.

Frequently asked questions

Is there anything better than CO2 laser?

For surface texture, fractional CO2 remains the most powerful tool. "Better" only makes sense within a goal: for support, microfocused ultrasound delivers what it cannot; for redness and visible vessels, other families respond better. There is no overall winner.

What is the best device for facial rejuvenation?

No single device rejuvenates a face, because facial aging happens in layers — skin, fat, support, bone. A device treats one or two of those layers. A plan treats the whole.

How many sessions are needed?

It depends on the aggressiveness. Powerful ablative protocols usually get there in a few passes, sometimes one; non-ablative ones work in a series, with intervals between them. The number comes from the assessment, not from the name of the device.

How long until results show?

What you see in the first days is an inflammatory reaction, not a result. New collagen takes weeks to organize, and an honest reading happens after that. Anyone promising a final result in a week is talking about swelling.

Does laser hurt?

There is discomfort, proportional to the depth. Ablative protocols use topical anesthesia and, depending on the area, other comfort measures. Non-ablative ones are usually well tolerated with topical alone.

Does laser lighten dark spots?

Some types do — and the same laser poorly calibrated can darken them. In Brazilian skin this is the most delicate decision in the whole topic, and it is the main reason for preparing the skin before the procedure.

Can I have laser in the summer?

You can, with strict sun protection and by avoiding direct exposure. But if your schedule lets you choose, the less sunny months reduce the risk of dark patches afterward. It is one of the few timing recommendations that makes a real difference.
