Why aesthetic treatments now come with recovery plans

A helpful illustration comes from a small, exploratory 2026 randomised split-face trial out of Shanghai, in which 30 people with atrophic acne scars had one side of the face treated with fractional CO₂ laser and the other with radiofrequency microneedling. Both treatments produced comparable improvement in the scars, but the radiofrequency-treated side healed with shorter periods of redness, pain, swelling and scabbing, and fewer cases of post-inflammatory hyperpigmentation.

In other words, one of the most consequential decisions about your downtime is made before the recovery kit even appears: which procedure is used, and how aggressively it’s performed.

Once the skin barrier has been disrupted, the fundamentals are refreshingly unglamorous.

Contemporary dermatology guidance generally comes back to the same short list: gentle cleansing, keeping healing skin adequately moisturised, avoiding irritating ingredients while the barrier repairs, and appropriate sun protection. A 2026 international consensus identified ingredients such as ceramides, cholesterol and hyaluronic acid as generally suitable around aesthetic procedures, while ingredients with greater irritation potential—including retinoids and exfoliating acids—were considered inappropriate during the immediate healing phase.

There’s some real clinical evidence behind this. In a 2025 randomised controlled trial of 60 patients undergoing fractional CO₂ laser, a skincare regimen containing hyaluronic acid of different molecular weights produced lower transepidermal water loss—a measure of barrier impairment—two weeks later, alongside less redness and a shorter duration of pain than the control regimen.

It’s worth noting that the 2026 consensus mentioned above, along with a separate 2025 set of recommendations for energy-based treatments, were both funded by SkinCeuticals, a L’Oréal brand. That 2025 paper is also honest about its own limits: it assigns its recommendations Level 5 evidence, meaning expert opinion, and says the evidence for many skincare actives remains sparse.

Still, none of that makes the basic advice wrong—cleanse gently, moisturise, protect from the sun, avoid actives that irritate. It does mean that evidence supporting moisturising damaged skin shouldn’t automatically be read as evidence that a particular, expensive post-laser kit is necessary.

If you’ve ever watched a spot heal, only for a dark mark to linger long after the redness has gone, you already know how stubborn pigmentation can be. For many with Asian skin—that is, those often falling within Fitzpatrick skin types III to V—that risk is worth planning for from the outset, not because anything’s gone wrong, but because it's simply part of how this skin tends to heal.

This is called post-inflammatory hyperpigmentation, or PIH—when inflammation prompts the skin to produce more pigment than usual. It can follow almost any inflammatory injury, but it shows up more often after lasers and other energy-based treatments, in skin that's naturally more prone to this kind of pigmentary change. And it’s worth saying clearly: this isn't something that affects all Asian skin equally. How much you're at risk depends on your skin phototype, which treatment you're having, how intense it is, and whether you've dealt with pigmentation before.

So here’s where the evidence gets a little more nuanced. A 2025 systematic review looked at 369 cases involving skin of colour—every patient in the included studies was Asian, and more than 95 per cent of the cases followed laser procedures. It found sunscreen, alone or combined with other measures, to be the most consistently successful preventive approach, though the evidence base was still limited. Then a 2026 analysis of randomised trials complicated that picture: sunscreen alone didn’t significantly reduce PIH compared with placebo, while several clinician-directed interventions—including topical corticosteroids and tranexamic acid—appeared more effective. The researchers were careful to flag that the studies behind this were still few and relatively small.

In practice, this means recovery planning starts well before you leave the clinic. If you're considered at higher risk of PIH, your clinician may factor that into which procedure they choose and how intensely they perform it. Afterwards, the priorities are simple but important: avoid unnecessary irritation while your skin heals, and be genuinely diligent about sun protection. In some cases, your dermatologist may also recommend additional preventive treatment based on your individual risk.

None of this means Asian skin needs a shelf full of extra products. It means pigmentation can outlast the initial redness and swelling by a long way, so it's worth taking seriously from the start—rather than trying to treat dark marks after they've already appeared.

Not every recovery consideration is about risk, though—some of it is simply about comfort, and that matters too. Speed isn't the only measure of whether something helps: a treatment doesn't have to accelerate wound repair to be genuinely useful to you.

If a treatment safely reduces redness, bruising, pain or swelling by even a day or two, and you have meetings, photographs or an event on the calendar, that can be worth something real. The important question is simply what benefit is actually being promised—and whether it’s the one you need.

LED, or photobiomodulation, is a good example of this nuance. There’s legitimate research suggesting low-level light can influence wound repair. A 2024 systematic review and meta-analysis of 18 randomised trials found improvement in some wound-healing outcomes. But those 670 cases in the review spanned diabetic ulcers, burns, surgical wounds and skin-graft donor sites—not predominantly cosmetic laser procedures—and the results were highly mixed. More recent evidence in specific wound types has also come back inconsistent.

So an LED session after treatment isn’t necessarily frivolous. But knowing that light can affect wound biology somewhere in medicine isn’t the same as knowing that the particular session on offer will meaningfully shorten your downtime after a particular facial procedure.

The gap widens further with some of the newer “regenerative” additions to aesthetic recovery—and this is where it pays to ask more questions before you say yes.

Growth factors have been studied directly after laser treatment. A systematic review and meta-analysis of seven randomised trials involving 169 patients found that topical epidermal growth factor temporarily improved one pigmentation measure and increased patient satisfaction. It did not, however, significantly reduce post-laser redness or improve transepidermal water loss—so no clear acceleration of barrier repair.

Platelet-rich plasma, or PRP, has a plausible wound-healing rationale too, but the clinical results have been genuinely mixed. Some small split-face trials have reported benefits when PRP is added to fractional CO₂ laser; others found no significant improvement over laser alone. A 2025 randomised, double-blind, split-face trial of 15 patients with atrophic acne scars compared PRP, non-cross-linked hyaluronic acid, their combination and a saline placebo after fractional CO₂ laser, and found no significant differences between groups on objective measures of skin colour, water loss or hydration. On some individual biometric readings, the single-ingredient treatments actually outperformed the combination. Yet both patients and physicians reported higher satisfaction with the PRP-plus-hyaluronic-acid combination than with either ingredient alone—a useful reminder that how a treatment feels and what it measurably does to your skin don’t always move together.

Polynucleotides have become especially visible in Asian aesthetics, with much of the clinical literature originating in South Korea. A recent systematic review, though, found only nine studies involving 219 patients, and judged the evidence low to moderate in quality. The studies pointed to possible benefits for skin rejuvenation—they didn’t establish polynucleotides as a necessary part of post-procedure recovery.

Exosomes sit further along the same curve of enthusiasm. Systematic reviews have found encouraging early improvements in hydration, elasticity, pigmentation and skin appearance, but also considerable variation in the products, protocols and study designs being used. Most human studies aren’t high-quality randomised trials, and long-term evidence remains limited.

The science here is genuinely interesting. The idea that an exosome treatment is therefore required for your skin to recover properly is a much harder case to make.

At the furthest end are extras like cosmetic IV drips. A 2026 position statement from the Association of Cutaneous Surgeons of India rated the evidence for aesthetic IV drips at Level 5 and gave them a recommendation grade of D, citing a lack of high-quality trials in healthy people. Correcting a genuine nutritional deficiency is medicine. Adding vitamins intravenously because you’ve just had a laser is a different proposition altogether.

None of this means modern aesthetic treatments should come without any aftercare—quite the opposite. As procedures become more targeted and technically sophisticated, good clinicians have more reason than ever to think carefully about treatment intensity, skin type, barrier disruption, pigmentation risk and possible complications.

But sophistication doesn’t have to mean complexity, and you shouldn’t feel you need the full menu to heal well.

For many office-based procedures, the parts of recovery with the strongest rationale remain simple: choosing the right treatment in the first place, protecting injured skin, avoiding unnecessary irritation, managing sun exposure and pigmentation risk, and knowing which symptoms might signal a complication.

Everything added on top of that can be judged by one straightforward question: what exactly is this supposed to improve?

Does it repair the skin faster? Does it reduce a particular symptom? Does it lower a recognised risk? Or does it simply make the recovery period more comfortable?

All of those outcomes can have real value. They just shouldn’t be sold to you as though they were the same thing.
