What Should I Avoid Before and After Lip Injections?

Most of what decides how your lips settle happens in the 48 hours either side of the appointment, not in the syringe. Bruising, prolonged swelling and uneven results are far more often the consequence of a glass of wine the night before or a hot gym class the morning after than of the filler itself. This guide sets out exactly what to avoid, when, and why.

Before lip injections, avoid blood thinning medicines and supplements, alcohol, and anything that raises your body temperature or blood flow. Afterwards, avoid touching the lips, makeup, heat, exercise, straws and smoking for the first 24 to 48 hours. At Halcyon Medispa, an aesthetic clinic in Marylebone, London, every lip filler treatment is planned in a consultation overseen by our Medical Director so the aftercare you are given fits your own medical history rather than a leaflet.

What to avoid before lip injections

In the week before your appointment the aim is simple: reduce anything that thins the blood, irritates the skin or dilates the vessels around the mouth, because all three make bruising and swelling more likely. None of the points below are absolute rules if a medicine has been prescribed to you, and you should never stop prescribed medication without asking the doctor who prescribed it.

1. Blood thinning medicines and supplements. Aspirin, ibuprofen and other non steroidal anti inflammatories thin the blood and raise the chance of a bruise. So do several common supplements: fish oil and omega 3, vitamin E, ginkgo biloba, high dose garlic and St John's wort. Where they are not prescribed, stopping them for about a week beforehand is the single most effective thing you can do to avoid bruising. Paracetamol is usually the sensible alternative for pain relief, and your practitioner will confirm this at consultation.
2. Alcohol, and a lot of caffeine. Alcohol dilates blood vessels and thins the blood, which is why a night out before treatment so often shows up as a bruise afterwards. Leave it for at least 24 to 48 hours beforehand. Heavy caffeine dehydrates and can leave you more sensitive on the day, so moderate it rather than eliminate it.
3. Makeup on and around the lips. Come to the appointment with a clean face, or at least clean lips. Makeup around the injection sites has to be removed anyway, and residue is an avoidable infection risk in an area that will have several small punctures in it.
4. Retinoids and strong exfoliating acids. Retinol, tretinoin, glycolic and salicylic acids all thin and sensitise the skin surface. Pause them on the lip area for a few days beforehand so the skin is calm rather than reactive when it is treated. This matters more than most people expect if you already have thin lips with delicate perioral skin.
5. Intense exercise and heat the day before. A hard training session, a sauna or a hot yoga class raises blood flow to the face and keeps it raised for hours. Treating warm, flushed tissue makes swelling and bruising more likely.
6. Arriving hungry, dehydrated or unwell. Eat before you come and drink water through the day. Feeling faint during an injectable appointment is common and almost always down to an empty stomach. If you have an active cold sore, a mouth ulcer, a dental infection or any infection near the lips, the appointment should be rescheduled rather than worked around.

There is one more thing worth planning rather than avoiding: timing. Give yourself at least two weeks between lip filler and any event you care about, and book dental treatment either two weeks before or two weeks after, never in the days around it.

What to avoid after lip injections

Aftercare matters more than preparation, because for the first day or two the filler has not fully settled and the tissue is inflamed and more vulnerable than usual. The list is short, and the first 48 hours carry almost all of it.

• Touching, pressing or massaging the lips. Fresh hyaluronic acid filler can be moved by firm pressure before it integrates, and the puncture sites are an entry point for bacteria. Leave them alone unless your practitioner has specifically shown you a massage technique and asked you to use it.
• Lipstick, balm, gloss and makeup for 24 hours. Anything applied to the lip surface risks introducing bacteria into the injection points, and plumping balms in particular contain irritants such as menthol and capsicum that are the last thing inflamed tissue needs.
• Alcohol and smoking for 24 to 48 hours. Alcohol worsens swelling and bruising. Smoking narrows the small vessels that supply the healing tissue and adds a repetitive pursing movement, so it works against you twice.
• Straws, and anything that makes you purse your lips. Sip from the glass, skip the straw, and postpone the wind instrument practice for a couple of days.
• Heat and hard exercise for 24 to 48 hours. Saunas, steam rooms, hot tubs, hot showers, sunbeds and vigorous training all raise blood flow and body temperature, which prolongs swelling. Gentle walking is fine.
• Sleeping face down. Sleep on your back with your head slightly raised on an extra pillow for the first two nights. Pressure on fresh filler is exactly what you have spent the day avoiding.
• Strong sun and tanning for a few days. Ultraviolet exposure increases inflammation in tissue that is already inflamed. Use an SPF lip balm once the first 24 hours have passed.
• Dental work, facials, peels and lasers for two weeks. Anything that stretches, heats or presses on the treated area belongs outside the settling window. Tell your dentist you have had lip filler if an appointment cannot be moved.
• Flying in the first 24 to 48 hours where you can avoid it. Cabin pressure and dry air tend to accentuate swelling rather than cause any harm, but most people would rather not spend a holiday at peak puffiness.

The recovery timeline, day by day

Knowing what is normal at each stage is what stops people panicking at the 24 hour mark, which is almost always the worst it looks. The pattern below is typical for hyaluronic acid lip filler, though everyone settles at their own pace.

How long do swelling and bruising last?

Swelling peaks at around 24 to 48 hours and settles substantially within three to five days, with the final shape usually clear at two weeks. Bruising, when it happens, follows the same course as any other bruise and typically fades over five to ten days. Both are normal parts of healing rather than signs that something has gone wrong.

A few practical things genuinely help. Cool compresses in the first 24 hours reduce swelling more than anything else available to you. Sleeping with your head slightly raised stops fluid pooling overnight, which is why lips look worst first thing in the morning. Staying well hydrated and keeping salt moderate for a couple of days makes a visible difference. Arnica, taken or applied as your practitioner advises, is popular for bruising, though the evidence for it is mixed and it is no substitute for avoiding blood thinners in the first place.

If small firm lumps persist beyond two weeks, that is worth a review rather than worry. Most soften on their own or respond to a light massage technique shown to you in clinic. Where filler has moved beyond the lip border over time, that is filler migration, a separate issue with its own assessment and, if needed, a dissolving treatment to reset before rebuilding.

When to contact the clinic straight away

Complications after lip filler are uncommon, and the great majority of what people notice in the first days is ordinary healing. A small number of signs are different, and they are time critical, so it is worth knowing them before treatment rather than looking them up at midnight.

• Skin that turns white, blotchy, dusky or grey around the lips or towards the nose, particularly with a mottled pattern.
• Pain that is severe, or that increases after the first few hours instead of easing.
• Spreading redness, heat, hardness or fever, which can indicate infection.
• Any change in vision, which needs emergency medical attention immediately.
• Blisters, ulceration or an area that feels cold compared with the surrounding skin.

These can indicate a vascular event, where filler has affected the blood supply, and it is treatable when acted on quickly. Contact the clinic that treated you at once, at any hour, and do not wait to see whether it settles overnight. This is one of the reasons to have injectables performed in a medical setting where an experienced practitioner and dissolving agents are available rather than at a pop up appointment.

Aftercare at Halcyon Medispa

Good lip results come from conservative technique, the right product for the anatomy, and a plan you can actually follow afterwards. At our Marylebone clinic every injectable plan is overseen by our Medical Director, Dr.OBT, and starts with an assessment of your lip shape, proportions and medical history rather than a set amount. You are given written aftercare, a point of contact, and a review so the result is judged once it has settled rather than while it is still swollen.

If you are still deciding, our Patient Journey page explains how consultation, treatment and review fit together, current treatment prices are published, and any packages and offers are listed openly. For lip texture and quality rather than volume, regenerative options such as polynucleotide treatment are sometimes the better first step, and we will say so if that is the case.
