Does a skin booster hurt?
It can sting: a skin booster is a run of many small injections, so it feels like a series of quick pricks across the area and not a single one. How much it bothers you varies from person to person, and published pain scores are averages from small trials, not a promise.
The authors of one polynucleotide trial describe the treatment as multiple intradermal injections, often placed as micro-droplets, that can be highly uncomfortable even with prior topical anaesthesia. In contrast, in the US trial behind the FDA summary of a hyaluronic acid booster that contains 0.3 per cent lidocaine, participants assessed the pain during injection as minimal. Both can be true, because the product, the numbing and the method differ.
What pain scores did the trials report?
In a split-face trial of 15 people, a conventional polynucleotide product averaged 5.04 out of 10 and a modified, ionisation-adjusted product averaged 3.39 (p < 0.005). The modified product also had less redness (40 against 60 per cent) and fewer raised injection marks (13.3 against 56.7 per cent), with no difference in the wrinkle scores. That tells you formulation matters, and not that any product used in a clinic will behave the same way.
No study read for this article compares polynucleotide and hyaluronic acid boosters head to head for pain, so this page does not say which hurts more. Polynucleotide products generally do not contain lidocaine, so numbing is usually separate for them; the article on PDRN, polynucleotides and salmon DNA explains what they are.
Do needle-free jets or devices hurt less than manual injection?
In one very small trial they did. Ten people had a polynucleotide product by 33-gauge needle, in a serial puncture pattern about 1 cm apart, on one side of the face, and by a needle-free jet on the other, after 5 per cent lidocaine-prilocaine cream for 30 minutes. Pain on a 10-point scale was 5.4 with the needle and 2.9 with the jet (p = 0.017), and satisfaction was higher on the jet side.
That is one device in ten people, and such devices are not available everywhere, so it is a pointer. Vibration is another non-drug aid: a review of 35 papers found it useful for lessening discomfort with needle procedures, with some literature on toxin and filler injections, though few dermatology papers were available and the techniques are not standardised.
Does numbing cream help for a skin booster?
Numbing cream is commonly used, but the booster trials read here gave cream to everyone, so none measures cream against none. What they show is that pain is lowered and not removed: scores were still around 5.4 out of 10 with manual injection after 30 minutes of cream, and creams differ from each other. In a randomised trial of 100 people having facial rejuvenation procedures, a compound lidocaine cream averaged 2.51 and a lidocaine-prilocaine cream 3.75 (p < 0.001), although the participants were not blinded.
A numbing cream is a medicine with limits on how much, over what area and for how long, and the article on numbing cream before a cosmetic procedure explains them. Ask what pain control is planned, instead of applying a cream yourself beforehand.
Is the pain the same for everyone, and are later sessions easier?
No two people rate it alike, and the same person can rate two sides of the face differently. In a study of 20 patients who had a poly-D,L-lactic acid skin booster injected into both cheeks over four sessions three weeks apart, the left cheek scored higher for pain than the right (p < .05). Men first reported more pain than women, but that difference faded over repeated sessions, and age was not linked to pain. The authors suggest right-sided brain dominance in pain processing as one possible reason and call for larger studies, so treat it as a curiosity and not a rule.
There is also a hint in the US hyaluronic acid booster data that later visits go more smoothly: injection site responses were recorded by 51.4 per cent after a touch-up and 54.4 per cent after a repeat treatment, against 79.4 per cent after the first treatment. That counts redness, bumps and the like, not pain scores, so it is not proof that the injections themselves hurt less.
What does a skin booster session involve, step by step?
The sequence below is the shape of a session. First, an assessment: your skin concerns, medical history, medicines and supplements, and anything that means waiting, such as an active infection or cold sore, an autoimmune flare, pregnancy or a recent facial procedure, as set out in the article on skin booster side effects and who should wait. This is where a doctor decides whether a booster is the right tool; what skinboosters fix and what they do not explains the aim.
Second, consent and photographs for the record. Third, the skin is cleansed. Fourth, numbing, according to the agreed plan, for example a cream left on for the time it needs. Fifth, the injections: the product is placed in many tiny points across the area, about 1 cm apart in one trial, which is why the area is covered quickly but felt repeatedly. Sixth, a check together and advice for the days ahead. Boosters are usually given as a course, and how long skin boosters last and how often to repeat sets out the evidence.
What can make a skin booster session more comfortable?
Three things have evidence behind them in the studies above: the numbing method, the product, and how it is delivered. A lidocaine-containing hyaluronic acid booster was rated minimal for pain during injection in the US trial; a modified polynucleotide gel scored lower than a conventional one; and a needle-free jet scored lower than manual injection in a very small trial. None of these is a guarantee, and not every option is offered everywhere.
Practical points follow from that. Say if you are anxious about needles, so that the plan can allow for it. Tell the doctor about blood thinners, fish oil and other supplements, since bruising is one of the common effects and the article on blood thinners and supplements before injections explains which to mention. Ask whether you can pause if it becomes too much.
What happens in the days after?
Redness, small bumps, swelling, bruising and tenderness are the usual local effects. In the US trial of a hyaluronic acid booster, 79.4 per cent of 199 treated people recorded some injection site response over 30 days: redness in 68.8 per cent, lumps and bumps in 63.3 per cent, swelling in 61.3 per cent, bruising in 57.8 per cent and pain in 52.8 per cent. Most were mild and lasted seven days or less, and the pain was mild in 47.2 per cent and lasted one to three days in 41.2 per cent.
Bumps lasted beyond 30 days in 8.0 per cent, so persistent bumps, pain that is getting worse, a spreading red area, fever or any reaction that is not settling are reasons to contact the clinic. The skin booster side effects article separates the aftercare rules that have evidence from those that are convention.
What should you ask before a skin booster?
Ask what pain control is planned, how the booster will be placed, how many sessions are expected and what the days after usually look like. At The Retreat Clinic in Setia Alam, skinboosters, including polynucleotides, are performed by Dr Ong, and the page on skin booster treatment describes the treatment.
