Understanding Bruising & Swelling After Polynucleotide Injections
Bruising and swelling are common side effects of polynucleotide injections. They occur when the needle disrupts small blood vessels (capillaries), causing blood to leak into the surrounding tissue, resulting in a bruise (ecchymosis). Swelling (edema) is the body’s natural inflammatory response to the injection.
Why Do Bruising and Swelling Occur?
The cause is the injection. A needle can puncture microscopic vessels; the likelihood depends on the treatment area’s vascularity (the under-eye area is delicate), your physiology, and any medications or supplements you take. The body’s inflammatory response causes localized swelling.
What to Expect in the First 24-48 Hours
After treatment, small, raised bumps at the injection sites are normal and typically resolve within a few hours. Mild redness and puffiness may also occur. Bruising often starts as small, reddish dots that darken to blue or purple over the next day. Swelling is most noticeable the morning after the procedure, especially around the eyes, and usually subsides within 48 hours.
Immediate Aftercare: Pro Tips to Reduce Discomfort After Injections
Actions in the first 48 hours post-treatment are critical for managing side effects. Cold therapy, elevation, and gentle care constrict blood vessels and reduce inflammation, leading to a faster resolution of bruising and swelling.
The Power of Cold Compresses and Elevation
Applying a cold compress is an effective immediate step. The cold causes vasoconstriction (narrowing of blood vessels), which limits blood leakage and reduces bruise size and intensity. For facial treatments, sleeping with your head elevated on an extra pillow for one to two nights helps drain fluid, reducing morning puffiness.

Gentle Handling and Avoiding Pressure
The treated area will be sensitive. Avoid rubbing, massaging, or applying pressure for at least 24-48 hours. This includes facial treatments, massages, or cleansing devices. When cleansing, use a gentle cleanser and pat the skin dry. Do not apply makeup for at least 12-24 hours to allow injection points to close, reducing infection risk.
Supplements & Topicals: Accelerating Your Polynucleotide Recovery
Certain supplements and topical products can support healing. They help manage inflammation and accelerate the reabsorption of bruised blood cells. Consult your doctor at Rejuva London before starting any new supplement, especially before a medical procedure.
Arnica Montana and Bromelain: Natural Anti-Inflammatories
Arnica montana is a homeopathic remedy used to reduce bruising, swelling, and pain, available in oral and topical forms. Patients can take oral arnica tablets a few days before their appointment and continue for several days after. Bromelain, an enzyme from pineapple stems, has been studied for anti-inflammatory properties that may reduce swelling and discomfort. Research in journals like the Journal of Oral and Maxillofacial Surgery has explored its efficacy in post-operative settings.
Topical Solutions: Vitamin K and Healing Balms
Topical Vitamin K oxide cream can be applied to a bruised area. Vitamin K is essential for blood clotting, and topical application may help fade bruises faster by breaking down pooled blood. After 24 hours, your doctor may recommend a healing balm or serum with ingredients like antioxidants and peptides to support skin barrier repair and soothe inflammation.
Lifestyle Adjustments for Optimal Healing: What to Avoid
Lifestyle choices impact the severity of bruising and swelling. Making temporary adjustments before and after your treatment can optimize healing. Avoid anything that thins the blood or increases blood flow and pressure to the face.
Medications and Substances to Temporarily Discontinue
Some medications and supplements have blood-thinning properties that increase bruising risk. Discuss your current medication list with your doctor during your consultation. For about one week before and a few days after treatment, avoid non-steroidal anti-inflammatory drugs (NSAIDs) like aspirin and ibuprofen, and high-dose supplements of Vitamin E, fish oil, garlic, and ginkgo biloba. Avoid alcohol for at least 24 hours before and after the procedure, as it dilates blood vessels and can exacerbate bruising.

Exercise, Heat, and Sun Exposure Post-Treatment
Strenuous exercise increases blood flow to treated areas, which can worsen swelling and create new bruises. Avoid vigorous workouts for at least 48 hours. Avoid excessive heat from hot showers, saunas, steam rooms, or direct sun for 2-3 days. Heat dilates blood vessels, counteracting cold compresses and potentially increasing inflammation.
The Rejuva London Difference: Doctor-Led Precision for Safer Injections
The most effective way to minimize bruising after injections starts before the injection. The practitioner’s expertise and technique are paramount in preventing complications. At Rejuva London, a doctor-led clinic on Harley Street, every injectable procedure is performed by a medical doctor with a background in facial anatomy and aesthetic medicine, ensuring high standards of safety and care.
Why Doctor-Led Technique Reduces Complications
A doctor’s understanding of facial anatomy—the location of arteries, veins, and nerves—is critical. This knowledge allows for strategic injection placement that avoids major vessels, reducing the risk of bruising. Our doctors may use a blunt-tipped cannula instead of a needle in certain areas, which can glide past blood vessels rather than piercing them.

Your Rejuva London consultation includes a medical history review to identify bruising risk factors. After your treatment, you receive personalized aftercare instructions for your procedure and skin type. Choosing a clinic based on medical expertise is key to a safe outcome, a principle detailed in our guide on how to choose the best doctor-led aesthetic clinic in London.
Your Polynucleotide Recovery Timeline & When to Seek Advice
Understanding the healing timeline helps set realistic expectations and plan your schedule. While healing rates vary, most side effects from polynucleotide injections are mild and resolve quickly. Know the difference between a normal recovery and signs that require contacting the clinic.
Typical Resolution of Bruising and Swelling
Mild swelling and redness are most prominent for the first 1-3 days and then subside. Bruising follows a predictable course, appearing darkest in the first couple of days before changing color—from blue/purple to green, then yellow—as the body reabsorbs the hemoglobin. Most bruising resolves within 7-10 days, though smaller bruises may fade in 3-5 days. Age, skin type, and overall health can influence this timeline.
Recognizing and Responding to Uncommon Side Effects
While rare, be aware of signs of a complication. Contact our clinic immediately if you experience severe or increasing pain, spreading redness and warmth, pale or mottled skin discoloration away from the bruise, or signs of infection like pus. Our doctor-led team provides post-treatment contact information for direct access to medical advice if concerns arise.
