Dermal fillers are one of the most popular aesthetic treatments in the UK — and for good reason. A skilled practitioner can restore lost volume, refine facial contours, and achieve natural-looking results in a single appointment. But the outcome you leave the clinic with is not always the outcome you keep. How you care for your skin in the hours, days, and weeks that follow plays a significant role in how well your filler settles, how long it lasts, and whether you avoid complications.

This guide covers everything you need to know about dermal filler aftercare: the universal rules that apply regardless of which area was treated, what swelling and bruising to expect, how to adapt your skincare routine, and the warning signs that require immediate attention. For area-specific advice, use the quick-reference section to navigate to the relevant guide.

Universal Filler Aftercare Rules (All Areas)

Whether you have had lip filler, cheek filler, jaw filler, or any other hyaluronic acid treatment, the following rules apply during the first 48 hours after your appointment. This period is critical — the filler is still integrating with surrounding tissue, and anything that increases blood flow, heat, or pressure at the injection site can worsen swelling or shift the product before it settles.

For the first 48 hours after any dermal filler treatment:

• Avoid vigorous exercise. Raised heart rate and blood pressure increase swelling and bruising. This includes the gym, running, cycling, swimming, yoga, and any sport. Light walking is acceptable.
• Avoid alcohol. Alcohol is a vasodilator — it widens blood vessels and increases circulation, which amplifies swelling and bruising. It also thins the blood, making bruising more likely and slower to resolve. Avoid for at least 24–48 hours, ideally longer.
• Avoid heat exposure. Saunas, steam rooms, hot baths, sunbathing, and sunbeds all raise skin temperature and dilate blood vessels. Heat can increase swelling and, in rare cases, may affect how the filler settles. Showers should be warm rather than hot.
• Avoid active skincare ingredients. Retinoids (retinol, tretinoin), AHAs (glycolic acid, lactic acid), BHAs (salicylic acid), and vitamin C are all exfoliating or potentially irritating at injection sites. Avoid these for at least 48 hours — ideally 72 hours for sensitive skin.
• Avoid makeup directly over injection sites. If injection points are visible, keep them free from cosmetics for at least 24 hours to reduce the risk of introducing bacteria into micro-puncture wounds.
• Avoid touching, rubbing, or pressing the treated area. The filler needs to settle in position. Unnecessary manual pressure — including sleeping face-down — can displace it.
• Avoid non-steroidal anti-inflammatory drugs (NSAIDs) unless medically necessary. Ibuprofen and aspirin thin the blood and can worsen bruising. Paracetamol is the safer choice for post-treatment discomfort.
• Stay upright for several hours. Lying flat immediately after treatment can increase fluid pooling and worsen swelling around certain areas, particularly the face.
• Stay hydrated. Hyaluronic acid filler attracts and retains water. Good hydration supports the settling process and overall skin health during recovery.

These rules are not arbitrary. Each one directly addresses a physiological mechanism that can compromise your result or increase the risk of complications. Your practitioner may provide slightly tailored advice for your specific treatment — always follow their post-care instructions alongside this general guidance.

Swelling and Bruising: What's Normal and When to Worry

Some degree of swelling and bruising after dermal fillers is entirely normal. The needles or cannulas used to deliver the filler cause minor trauma to tissue, and the body responds with inflammation as part of the natural healing process. For most patients, this is mild and resolves within a week.

What to expect:

• Day 1–3: Swelling is typically at its peak. The treated area may look fuller or puffier than intended. This is normal and does not reflect your final result.
• Day 3–7: Swelling begins to subside. Bruising may appear or deepen before it fades. Bruises often turn yellow or green as they resolve — this is a normal part of the healing process.
• Week 1–2: Most swelling and bruising resolves. The filler begins to settle and integrate.
• Week 2–4: Final results become visible. Some areas (particularly the lips) may retain mild swelling for up to four weeks.

Managing swelling and bruising:

• Apply a clean, cold compress (wrapped in a cloth — never ice directly on skin) for 10-minute intervals in the first 24 hours.
• Arnica cream or oral arnica supplements may help reduce bruising, though evidence is anecdotal.
• Sleep with your head slightly elevated on the first night to reduce fluid pooling.
• Avoid heat, alcohol, and exercise as outlined above — all worsen both.

When to seek advice:

Most post-filler changes are cosmetic and resolve naturally. However, contact your practitioner if you experience:

• Swelling that is significantly worsening after 72 hours rather than improving
• Pain that is escalating rather than settling
• A lump or nodule that feels hard and does not soften over two weeks
• Any signs listed in the vascular occlusion section below

Exercise After Dermal Fillers

The 48-hour rule on exercise is one of the most commonly asked-about restrictions — and one of the most commonly ignored. Here is why it matters.

When you exercise, your heart rate and blood pressure rise, increasing blood flow throughout the body. At an injection site where minor tissue trauma has occurred, this increased circulation amplifies swelling and increases the risk of bruising spreading. More significantly, raised blood pressure can increase the risk of post-injection haematoma (a collection of blood under the skin).

What counts as exercise for these purposes:

• Cardiovascular training: running, cycling, HIIT, rowing, swimming
• Resistance training: weights, resistance bands, bodyweight exercises
• Classes: spin, bootcamp, aerobics, yoga (particularly vigorous styles such as Bikram or hot yoga — the heat element doubles the concern)
• Sports: racquet sports, team sports, martial arts
• Any activity that causes your heart rate to rise significantly or makes you perspire heavily

Light walking, gentle stretching, and low-intensity activity are generally acceptable. If in doubt, rest.

After 48 hours, you can typically return to your normal exercise routine. If your treatment involved a more sensitive area or a larger volume of filler, your practitioner may advise waiting slightly longer. For treated areas that involve significant muscle movement — such as the jaw — your practitioner may offer specific guidance.

Flying After Dermal Fillers

Flying within 24–48 hours of filler treatment is generally not recommended. Aircraft cabins are pressurised environments with low humidity, which dehydrates the skin and can temporarily affect swelling patterns. The change in cabin pressure can also exacerbate swelling, particularly in the first 24 hours when tissue inflammation is at its peak.

If you must fly within 48 hours, stay well hydrated, apply a gentle moisturiser to the treated area (avoiding active ingredients), and avoid alcohol during the flight. Keep the treated area protected from direct air-conditioning vents.

For longer-haul travel, most practitioners advise waiting a minimum of two weeks before flying to allow results to fully settle and to ensure any complications — particularly vascular occlusion — can be identified and managed promptly. Access to a practitioner who can administer hyaluronidase (the enzyme used to dissolve filler in an emergency) is important in the immediate post-treatment period.

Sleeping After Dermal Fillers

How you sleep in the first night or two after treatment can affect the final position of your filler. The product is not yet fully integrated and remains somewhat malleable during this initial period.

Recommendations for the first 1–3 nights:

• Sleep on your back where possible, with your head slightly elevated (an extra pillow helps).
• Avoid sleeping face-down, which places direct pressure on treated areas.
• Try to avoid pressing your face into the pillow if you sleep on your side — a travel or U-shaped pillow can help keep your face off the surface.
• Avoid tight headwear or hats that press against treated areas overnight.

After approximately 72 hours, the filler has generally integrated sufficiently that normal sleeping positions are fine. If you have had a significant volume of filler or are prone to sleeping in one position, erring on the side of caution for an additional night is sensible.

Skincare After Fillers

One of the most frequent questions after dermal filler treatment is when to resume a normal skincare routine. The answer depends on which products you use.

What to avoid for at least 48–72 hours:

• Retinoids (retinol, retinaldehyde, tretinoin): These vitamin A derivatives increase cell turnover and can cause irritation at injection sites. Avoid for a minimum of 48 hours; if you use a prescription-strength retinoid, wait 72 hours or until any tenderness has completely resolved.
• AHAs and BHAs (glycolic acid, lactic acid, mandelic acid, salicylic acid): Chemical exfoliants can irritate compromised skin and should be paused for 48–72 hours.
• Vitamin C (l-ascorbic acid in particular): High-potency vitamin C formulations can be sensitising. Pause for 48 hours.
• Niacinamide at high concentrations: Generally well tolerated, but if your skin is reacting to the treatment, consider pausing for 24 hours.
• Physical scrubs and exfoliants: Avoid mechanical exfoliation directly over injection sites for at least a week.
• Facial massages and microcurrent devices: Do not use these over treated areas for at least two weeks.

What is safe to continue:

• Gentle, fragrance-free cleanser
• Hydrating serum (hyaluronic acid, ceramides, glycerin)
• Moisturiser
• Broad-spectrum SPF — this is non-negotiable. Newly treated skin is more susceptible to UV-induced inflammation, and post-treatment hyperpigmentation is a real risk if sun protection is neglected.

When reintroducing active ingredients, do so one at a time and observe how your skin responds. If you had any adverse reaction or prolonged swelling, consider waiting a full week before resuming actives.

Area-Specific Aftercare Quick Reference

Different treatment areas carry distinct aftercare considerations. The lips, for example, swell considerably more than the cheeks; the nose requires additional caution around pressure; the jaw involves significant muscle use that can affect recovery. Use the links below to access detailed, area-specific guidance:

• Cheeks: cheek filler aftercare — volume restoration, facial contouring, swelling timelines for mid-face treatment
• Lips: lip filler aftercare — the area most prone to significant swelling; specific advice on eating, drinking, and kissing post-treatment
• Nose: nose filler aftercare — non-surgical rhinoplasty carries unique considerations given proximity to nasal vasculature
• Jaw: jaw filler aftercare — jawline and chin filler; advice on eating and chewing during recovery
• Bum: bum filler aftercare — non-surgical bum augmentation with specific guidance on sitting, sleeping, and physical activity

If your treatment area is not listed above, the universal rules in this guide apply in full. Your practitioner should also provide written aftercare specific to your treatment.

How Long Does Filler Recovery Take?

"Recovery" after dermal fillers is generally mild compared to surgical procedures, but the timeline to final results is longer than many patients expect.

Typical recovery milestones:

For most patients, the social downtime is minimal — many people return to work the following day. The main concern is cosmetic: looking slightly swollen or bruised for up to a week. Strategic scheduling (avoiding important events within 2 weeks of treatment) is sensible, particularly for first-time filler patients who cannot predict how their skin will respond.

Lip filler tends to involve the most noticeable initial swelling; cheek filler tends to be less dramatic. Volume of product injected is also a factor — larger treatment volumes generally involve more swelling and a longer integration period.

When to Contact Your Practitioner Urgently

The vast majority of filler treatments proceed without serious complications. However, one rare but serious complication — vascular occlusion — requires immediate intervention and every patient should be aware of its signs.

Vascular occlusion occurs when filler is inadvertently injected into or compresses a blood vessel, restricting blood flow to the surrounding tissue. Without prompt treatment, this can cause tissue necrosis (permanent skin damage). The window for effective treatment is narrow — hours, not days.

Signs of vascular occlusion — seek immediate help if you notice any of these:

• Blanching or white patches on the skin near the injection site that do not resolve within seconds
• Sudden, severe or worsening pain that feels disproportionate to what you would expect from a cosmetic injection
• Skin colour changes — purple, blue, grey, or mottled discolouration in the treated area
• A blotchy or net-like appearance (livedo reticularis pattern) in the skin
• Vision changes — blurring, loss of vision, or eye pain after facial filler (indicates potential ophthalmic vessel involvement, which is a medical emergency)

If you suspect vascular occlusion, contact your practitioner immediately. If you cannot reach them, go to A&E. Time is critical. Any reputable practitioner will have hyaluronidase available and will prioritise emergency contact from a patient reporting these symptoms.

Other less urgent but still notable concerns include hard lumps that persist beyond four weeks, signs of infection (increasing redness, warmth, discharge), or granuloma formation. These should be assessed by your practitioner rather than managed at home.

Getting the Most From Your Filler Investment

Dermal fillers are not permanent — hyaluronic acid fillers typically last between 6 and 18 months depending on the product used, the area treated, and how your body metabolises the material. However, there is much you can do to support longevity and maintain the quality of your result.

Protect your skin from UV damage. UV radiation accelerates hyaluronic acid breakdown and degrades collagen, which undermines the structural context in which your filler works. Daily SPF 30 or higher is the single most effective thing you can do to extend results and maintain overall skin quality.

Maintain good hydration — inside and out. Hyaluronic acid holds many times its weight in water. Drinking adequate water and using hydrating skincare supports optimal filler performance and appearance.

Avoid significant weight fluctuations. Repeated significant weight gain and loss cycles affect facial fat compartments, which interact with filler. Stable body composition supports more predictable and lasting results.

Consider supporting treatments. Skincare with retinoids and peptides supports collagen production, which reinforces the structural results of volume-based filler treatments. Your practitioner can advise on a skincare routine that complements your aesthetic plan.

Book a review appointment. Most practitioners offer a two-week review after filler treatment. Attending this appointment allows your practitioner to assess how the filler has settled, identify any asymmetries, and top up if appropriate. Do not skip this — it is part of the treatment.

Plan treatment timing thoughtfully. If you have an important event, aim to have filler at least three to four weeks beforehand to allow complete settling and any touch-up work. Avoid back-to-back treatments in the same area; filler needs time to fully integrate before more product is added.

Understand that filler is not a permanent solution, and that top-up appointments before complete dissolution will generally give better, more consistent results than waiting until the filler has fully gone. Discuss a treatment plan with your practitioner that aligns with your aesthetic goals and budget.

Dermal filler aftercare is not complicated, but it does require attention during the first 48–72 hours when the outcome is most malleable. Follow the universal rules consistently, seek area-specific guidance where relevant, and do not ignore any of the warning signs for vascular occlusion.
