A consistent aftercare protocol does more for review scores than any single product upgrade.
For licensed UK aesthetic practitioners, the post-treatment window is where clinical outcomes are won or lost. Patients who understand what to expect, and what to avoid, heal faster and report fewer complications. Yet aftercare guidance across HA fillers, skin boosters, polynucleotides, and thread modalities is often fragmented across manufacturer leaflets and clinic-specific handouts. This reference consolidates the key evidence-based principles into a single practitioner resource, covering immediate management through to the 72-hour mark and beyond.

General First-24-Hours Principles
Regardless of modality, the first 24 hours post-treatment share common management priorities. The injection zone will typically display erythema, localised oedema, and some degree of tenderness. These are expected inflammatory responses and are not, in isolation, indicative of complication. Your aftercare communication must make this distinction clearly for each patient.
- Apply a clean, cold compress wrapped in gauze (not ice directly against skin) for 5 to 10 minutes post-procedure to reduce immediate oedema, in line with guidance from the British College of Aesthetic Medicine (BCAM) on filler aftercare (source: BCAM patient information on dermal fillers).
- Keep the patient upright for at least four hours post-treatment if any material was placed in the mid or lower face.
- Advise patients that mild asymmetry in the first 48 hours is common and attributable to differential swelling, not placement error.
- Document the batch number, volume, and injection depth for all products used. This is essential if a vascular event or delayed hypersensitivity occurs.
HA Filler Aftercare
Hyaluronic acid fillers attract water by nature. Patients should be counselled that treated areas may appear more voluminous in the first 24 to 72 hours as the material hydrates. Final results are typically assessable at two weeks (source: manufacturer post-treatment guidance for HA filler products; consult individual product summary of product characteristics).
Key instructions for HA filler patients:
- No massage or manipulation of the treated site for a minimum of two weeks unless specifically instructed by the treating practitioner (for example, to smooth a visible bolus).
- Encourage gentle facial cleansing with clean hands and a mild, non-foaming cleanser from 24 hours post-treatment. Avoid flannel cloths or exfoliating brushes over the treated zone for at least one week.
- Arnica-based topicals (for example, Auriderm post-procedure gel) may be applied to reduce bruising in the peri-orbital and perioral areas. There is observational clinical data supporting the use of vitamin K oxide formulations in bruise resolution (Auriderm manufacturer clinical information).
- Signpost patients to your dermal filler aftercare range for appropriate topical products.
Skin Booster and Polynucleotide Aftercare
Skin booster products that work by intradermal hydration and polynucleotide preparations that stimulate fibroblast activity share a common mechanism: they require an intact dermal environment to deliver their effect. Post-treatment, multiple injection papules are normal and typically resolve within 12 to 24 hours.
Practitioner-level aftercare notes:
- Advise patients that full results from polynucleotide protocols develop gradually over four to six weeks, reflecting the time required for collagen remodelling. This timeline applies to preparations operating through PDRN receptor stimulation (manufacturer post-treatment guidance; consult individual product SPCs).
- For hydration-focused preparations, patients may notice visible papules for longer (up to 48 hours) due to placement depth and volume per depot. This is expected and not a red flag.
- Avoid pressure on papule sites during cleansing for 24 hours.
- Topical antiseptic aftercare is particularly important for skin booster and polynucleotide patients, given the higher number of injection points per session. See the antiseptic prep section below.
- View the skin booster collection for products in this category.
Thread Aftercare
Absorbable PDO and PCL thread treatments carry a distinct aftercare profile compared to needle-injected modalities, owing to the mechanical tissue manipulation involved. Patients experience more pronounced oedema, a degree of puckering at entry points, and a longer recovery window than with most injectables.
- Advise against large jaw movements (wide yawning, chewing hard foods) for the first five to seven days, particularly where lifting threads have been placed in the lower face or jowl region.
- Patients must sleep on their back, elevated, for the first three nights to limit dependent oedema and mechanical displacement risk.
- Entry point sites must be kept clean and dry for 48 hours. Apply a small amount of antiseptic preparation (see below) to entry sites at each dressing change.
- Visible suture ends at entry points, if present, should not be pulled by the patient. They should return to clinic for trimming.
- Final thread results are typically visible at eight to twelve weeks once inflammation resolves and collagen apposition around the thread has occurred (source: manufacturer post-treatment guidance; consult individual product instructions for use).
What to Avoid: Heat, Exercise, Makeup, and Pressure
All injectable and thread patients should receive written guidance on avoidance behaviours. The following timeframes represent a pragmatic, evidence-informed baseline. Individual clinical judgement and patient risk profile may indicate extending these windows.
- Heat exposure (saunas, steam rooms, hot baths, sunbeds, direct sun): avoid for 48 hours post-treatment. Heat increases vasodilation and oedema, and may accelerate product migration in superficially placed HA. Sun protection (SPF 50) is required any time the patient is outdoors in the two-week post-treatment window.
- Strenuous exercise: avoid for 24 hours minimum. Elevated heart rate increases blood pressure at injection sites and prolongs bruising and swelling. For thread patients, extend to 48 to 72 hours.
- Makeup: avoid for a minimum of 12 hours post-treatment to allow injection points to close and to reduce infection risk. Use only clean brushes and fresh products when returning to makeup application.
- Pressure and massage: as above, two weeks for HA filler. Thread patients should avoid any facial massage for four weeks minimum.
- Alcohol: advise patients to avoid alcohol for 24 hours, as it promotes vasodilation, worsens bruising, and increases oedema.
- Dental treatment and facial procedures: defer for two to four weeks. Any needle-based or physically manipulative procedure risks displacement or secondary infection in the treated zone.
Red-Flag Symptoms and When Patients Must Call
Every patient must leave the clinic with a clear, written list of symptoms that require immediate contact with the treating practitioner. Verbal communication alone is insufficient. The following are the minimum red-flag criteria to communicate, referenced against NICE Clinical Knowledge Summaries guidance on facial procedure complications and the BCAM emergency guidance framework.
- Vascular compromise signs (call immediately, do not wait): blanching or white discolouration of skin beyond the immediate injection zone, mottled or dusky skin colour, severe pain disproportionate to the procedure, or any loss of vision including blurring, double vision, or partial field loss. These signs indicate possible vascular occlusion and require emergency intervention within minutes. Practitioners must have hyaluronidase immediately to hand for any HA filler treatment session (source: NICE Clinical Knowledge Summaries; BCAM emergency protocols).
- Signs of infection (call within the day): increasing rather than resolving redness after 48 hours, warmth, pus, fever, or spreading erythema. Late-onset nodules appearing more than two weeks post-treatment may indicate biofilm and require prompt clinical assessment.
- Delayed hypersensitivity: firm, tender nodules appearing two to four weeks post-treatment are a recognised complication of HA filler and may require hyaluronidase or corticosteroid management. Patients must not self-treat.
- Thread-specific concerns: visible thread extrusion through skin, or a sudden loss of the corrective effect with localised swelling, requires immediate clinical review.
The Role of Antiseptic Skin Prep in Aftercare
Post-treatment antiseptic care is a continuation of the sterile field principle, not an optional extra. For all modalities, advise the use of a medical-grade skin antiseptic for the first 24 to 48 hours on injection points and entry sites. Clinisept+ (manufactured by Clinisept Aesthetics UK) is widely used in aesthetic practice. It contains stabilised hypochlorous acid (HOCl), which matches the body's own immune chemistry and is appropriate for use directly on broken skin. It carries a CE medical device classification for wound and skin management. Clinisept+ does not require dilution and will not disrupt healing tissue in the way that some alcohol-based preparations can (source: Clinisept Aesthetics UK clinical information, available from the manufacturer).
Practical guidance:
- Instruct patients to apply a small amount of Clinisept+ to a clean cotton pad and gently blot (not rub) each injection point twice daily for 48 hours.
- Clinisept+ may also be used for initial skin decontamination pre-treatment as part of standard prep.
- Where Clinisept+ is unavailable, a 0.9% saline wipe is preferable to alcohol swabs on broken skin post-treatment.
Key Takeaways
- First-24-hours management is largely shared across modalities: cold compress, upright posture, no heat or exercise, no makeup for 12 hours minimum.
- HA filler patients should avoid massage for two weeks and may use arnica-based topicals (for example, Auriderm) for bruise resolution.
- Skin booster and polynucleotide results develop over four to six weeks. Multiple injection papules are expected and resolve within 24 to 48 hours.
- Thread patients have a more restricted recovery window: no large jaw movements for five to seven days, sleep elevated for three nights, defer all facial massage for four weeks.
- Written red-flag criteria are mandatory for every patient, with specific emphasis on vascular compromise signs requiring immediate action.
- Clinisept+ (HOCl) is a suitable aftercare antiseptic for injection points across all modalities and does not disrupt healing tissue.
- Every clinic should hold hyaluronidase and an emergency protocol. The BCAM and NICE Clinical Knowledge Summaries provide the reference framework for complication management.
