Polynucleotide aftercare is simple, but the first few days matter. If you have booked or recently had polynucleotide injections, the main aims are to protect the injection site, reduce swelling and bruising, support product settling, and allow the skin to recover calmly.
At Angel White Aesthetics, polynucleotides are offered as a consultation-led under-eye treatment in both Littlehampton and Hove, with treatment focused on supporting under-eye skin regeneration. This guide explains what to expect after treatment, what to avoid after polynucleotides, and how the recovery timeline usually looks from day 0 to day 14.
What can I do after polynucleotides?
After polynucleotides, keep the treated area clean, avoid touching or rubbing the skin, use gentle skincare, apply SPF, drink plenty of water, and follow your practitioner’s specific post-treatment care. Avoid makeup, alcohol, intense exercise, swimming, saunas, steam rooms, hot showers, sunbeds, and strong active skincare until the skin has settled.
Mild redness, swelling, tenderness, bruising, itching, puffiness, and small polynucleotide bumps can be normal immediate responses. These are usually part of post-injection physiology, not a sign that anything has gone wrong. However, symptoms should gradually improve rather than worsen.
Why aftercare matters after polynucleotide injections
Polynucleotides, including Plinest, are injectable regenerative treatments used to support skin quality, hydration, elasticity, and repair. They do not behave like dermal filler. Instead of creating instant volume, they work through product integration and delayed regenerative responses in the skin.
Because the treatment involves tiny injection points, aftercare is important for four reasons:
- reducing infection risk at the injection site
- supporting bruising mitigation and swelling control
- allowing product settling without unnecessary pressure
- helping the lymphatic system clear temporary fluid build-up
This is especially important for under-eye polynucleotides, where delicate skin and natural fluid retention can make swelling or puffiness look more noticeable.
Day 0: Immediately after treatment
On the day of treatment, expect the skin to look slightly red, raised, or puffy. Small bumps can appear where the product has been placed. This is usually most visible straight after the appointment and can look more obvious under the eyes.
For the first 6 hours, avoid touching the treated area. Do not rub, massage, press, or apply makeup. Your skin has tiny entry points, so clean hands and minimal contact are essential.
You should also avoid heat, intense cold, direct sun, alcohol, swimming, and strenuous exercise. These can increase blood flow, encourage swelling, or raise the risk of irritation.
If your practitioner recommends it, a clean cool compress may help calm warmth or puffiness. Do not apply ice directly to the skin.
Day 1: The first 24 hours
Day 1 is usually when clients ask the most aftercare questions: can I wear makeup after polynucleotides, can I exercise after polynucleotides, or can I drink alcohol after polynucleotides?
For the first 24 hours, keep things gentle. Cleanse with a mild cleanser only after the initial no-touch period has passed. Avoid exfoliating acids, retinol, vitamin C, scrubs, facial massage, and strong active skincare.
Avoid alcohol for 24 hours, as it may contribute to bruising or swelling. Avoid strenuous exercise and swimming for 12–24 hours, or longer if your practitioner advises. Sun avoidance is also important; use SPF50 and avoid sunbeds or direct sun exposure while redness or swelling remains.
Sleep on your back where possible, with your head slightly elevated. This can help lymphatic decongestion and may reduce morning puffiness.
Day 3: Swelling, bruising, and product settling
By day 3, redness is often calmer, but bruising can become more visible as it changes colour. Mild swelling can also linger, especially around the under-eye area. This does not mean the treatment has failed or migrated.
If you are wondering how long polynucleotide bumps last, many small raised points settle within a few days. Under-eye bumps may take slightly longer because the skin is thin and the lymphatic system clears fluid gradually.
Continue gentle skincare, SPF, hydration, and sun avoidance. Avoid facials, massage, peels, microneedling, laser, sauna, steam rooms, and hot yoga unless your practitioner has cleared you.
Contact your clinic if swelling is getting worse rather than better, if the area feels increasingly painful, or if you notice heat, spreading redness, pus, fever, rash, or any visual symptoms.
Day 7: Most early downtime should be improving
For many clients, polynucleotide downtime is mild and manageable. By around day 7, most early post-injection changes should be settling. Bruises may still be fading, but swelling, tenderness, and visible bumps should be improving.
This is a good point to return to normal skincare gradually, but do not rush active ingredients if the skin still feels sensitive. A gentle cleanser, simple moisturiser, and SPF remain the safest routine.
Do not judge your final result at this stage. Polynucleotide recovery and polynucleotide results are on different timelines. Recovery is about calming the injection response. Results develop more gradually as skin quality, hydration, and regenerative activity improve.
Day 14: Returning to your usual routine
By day 14, most people are back to their normal routine. If your skin is calm, your practitioner may allow active skincare or other aesthetic treatments to be reintroduced. However, timing should be personalised, especially if you are planning facials, chemical peels, laser, microneedling, or further injectables.
At this stage, you may notice early improvements in skin hydration, texture, or brightness. More visible changes often develop over the following weeks, depending on your treatment plan, skin condition, lifestyle, and the number of sessions recommended.
For Plinest and other polynucleotide treatment plans, follow-up treatments may be advised in a course. Angel White will guide you on the right schedule during your consultation and aftercare review.
What to avoid after polynucleotides
Avoid the following until your skin has settled or your practitioner confirms it is safe:
- touching, rubbing, or massaging the treated area
- makeup too soon after treatment
- alcohol for 24 hours
- strenuous exercise and swimming for 12–24 hours
- saunas, steam rooms, hot showers, hot yoga, and sunbeds
- direct sun exposure without SPF
- retinol, exfoliating acids, scrubs, and strong active skincare
- facials, peels, laser, microneedling, or facial massage too soon
These restrictions are not just generic injectable aftercare. They help reduce unnecessary inflammation, support product integration, protect the injection site, and minimise the risk of bruising or irritation.
When should you contact your practitioner?
Mild redness, swelling, bruising, tenderness, itching, and small bumps are common after polynucleotide injections. These should generally improve within a few days.
Contact Angel White Aesthetics or your treating practitioner if symptoms persist, worsen, or feel unusual. Seek urgent advice for severe pain, spreading redness, significant heat, pus, fever, rash, hives, sudden severe swelling, or any vision changes after under-eye treatment.

FAQs
What should you avoid after polynucleotides?
Avoid touching, rubbing, makeup, alcohol, strenuous exercise, swimming, saunas, steam rooms, sunbeds, hot showers, and strong active skincare immediately after polynucleotides. These can increase irritation, bruising, swelling, infection risk, or delay product settling at the injection site.
How long does swelling last after polynucleotides?
Mild swelling after polynucleotides usually improves within a few days, although under-eye puffiness can last slightly longer because the area holds fluid easily. Swelling should gradually settle. If it worsens, feels painful, or persists, contact your practitioner.
Can I wear makeup after polynucleotides?
Avoid makeup after polynucleotides for at least the initial post-treatment period your practitioner recommends, commonly around 12–24 hours. This helps protect tiny injection points, reduces infection risk, and allows redness, swelling, and sensitivity to calm before applying cosmetics.
Can I exercise after polynucleotides?
Avoid strenuous exercise after polynucleotides for 12–24 hours, or longer if advised. Exercise increases heat and blood flow, which may worsen swelling or bruising. Gentle walking is usually fine, but avoid hot yoga, heavy lifting, swimming, and intense cardio.
Can I drink alcohol after polynucleotides?
Avoid alcohol for 24 hours before and after polynucleotides where possible. Alcohol can increase flushing, swelling, dehydration, and bruising risk. Choose water instead and follow your practitioner’s post-injection care instructions for the smoothest recovery.
How long do polynucleotide bumps last?
Small polynucleotide bumps often settle within a few days as the product integrates and swelling reduces. Under-eye bumps can sometimes be more visible because the skin is thinner. If lumps persist, worsen, or feel painful, contact your clinic.
