A Guide to Skin Booster Aftercare
Skin boosters, including polynucleotide-based products and injectable hyaluronic acid formulations, have become a popular part of many practitioners’ skin quality offerings. While the treatments themselves are typically quick, how a patient looks after their skin in the days that follow can influence both comfort and the overall outcome. This guide sets out general aftercare principles that practitioners may wish to adapt into their own patient advice sheets.
Immediately After Treatment
It is common for patients to experience some redness, mild swelling, or small bumps at injection points in the hours following a skin booster treatment. These effects are generally expected to settle within a day or two, though this can vary between individuals and treatment areas. Patients should be advised to avoid touching or applying pressure to the treated area unnecessarily, and to hold off on applying makeup for several hours, or as advised by the treating practitioner, to reduce the risk of irritation or infection.
A cool compress may help with comfort in the initial period, though this should be guided by individual clinic protocol rather than presented as a universal fix, as sensitivity varies from patient to patient.
The First Few Days
Patients are often advised to avoid strenuous exercise, saunas, steam rooms, and swimming for a short period after treatment, as increased blood flow and heat may worsen swelling. Sun exposure and sunbeds are typically best avoided too, and a broad-spectrum SPF is generally recommended as part of daily skincare regardless of recent treatment. Alcohol may increase the likelihood of bruising and is often advised against for a day or so post-treatment.
Patients should be encouraged to keep the area clean and to avoid harsh actives such as retinoids or strong exfoliants until any visible reaction has settled, resuming their usual skincare routine gradually and in line with practitioner advice.
Setting Realistic Expectations
Skin boosters are generally understood to work gradually, with hydration and skin quality improvements building over a course of sessions rather than appearing after a single visit. Clinical studies suggest that ingredients such as polynucleotides may help support the skin’s own repair processes, but individual response varies and results are not guaranteed. Practitioners should ensure patients understand that maintenance treatments are usually required to sustain results over time, and that skin booster treatment is not a substitute for a broader skincare and lifestyle approach.
Clear written aftercare advice, alongside a way for patients to contact the clinic if they have questions or concerns, helps support both patient confidence and safety.
When to Seek Advice
Patients should always be told what a normal healing response looks like versus signs that warrant contacting the clinic, such as significant or worsening swelling, signs of infection, or a reaction that does not settle within the expected timeframe. Having this information available in writing, in addition to verbal advice given at the time of treatment, supports better patient understanding and follow-up care. A simple traffic-light style leaflet, covering what is expected, what to monitor, and when to call the clinic, can be a useful addition to verbal aftercare instructions given on the day.
Supporting Consistent Aftercare Across a Clinic
Where more than one practitioner delivers skin booster treatments within a clinic, it is worth reviewing aftercare advice periodically to ensure it remains consistent, up to date, and aligned with the specific products being used, since formulations and manufacturer guidance can differ. Building aftercare communication into the patient journey — for example, a follow-up message a day or two after treatment — can also help identify any concerns early and reinforces a sense of ongoing care beyond the appointment itself.
Documenting the aftercare advice given, alongside batch numbers and any reactions noted, supports good clinical record-keeping and can be valuable if a patient has questions further down the line.
