Polynucleotides
Polynucleotide treatment courses: why results are gradual
Polynucleotide treatment is usually planned as a course rather than a one-off appointment. Understanding the timeline helps you judge subtle skin-quality changes realistically and plan around possible downtime.
Why the change is not immediate
Polynucleotides are injectable chains of purified DNA fragments used with the aim of supporting skin quality. Unlike a traditional dermal filler, the purpose is not to create immediate facial volume or reshape a feature. Any visible improvement is expected to develop gradually as the treated skin responds over time.
For this reason, the appearance immediately after an appointment is not the final result. Early swelling or small raised areas can temporarily make the skin look different, but these are treatment reactions rather than the intended longer-term change. Progress is better judged after the skin has settled and enough time has passed between sessions.
Why several sessions may be recommended
Published facial studies have commonly assessed a series of treatments rather than a single session. A 2026 prospective split-face study, for example, evaluated three sessions at three-week intervals and measured outcomes up to week 12. Other observational work has examined three-session courses for areas including the face, neck and décolletage.
At Dr Maryam Aesthetics, an initial polynucleotide course is commonly planned as three sessions spaced approximately two to four weeks apart. That is a starting framework, not a promise or a universal prescription. The product, treatment area, interval and total number of sessions should be chosen after assessment and may need to change according to tolerance and response.
What can be reviewed during the course?
The aim may include a gradual improvement in hydration, fine texture, elasticity or the appearance of fine lines. These changes can be subtle, and different concerns may respond differently. Standardised photographs, taken in consistent lighting and without filters, can be more useful than checking the mirror every day.
A review should consider whether the original concern is changing, whether the treatment has been tolerated and whether the plan still makes sense. It should not assume that more treatment is automatically better. If there is little meaningful benefit, the clinician should reconsider the diagnosis, expectations and alternatives rather than simply continuing the same course.
What does the evidence tell us?
Recent prospective and observational studies report improvements in several measures of facial skin quality after polynucleotide treatment. However, the evidence base remains limited: studies are often small, may use different products and outcome measures, and some lack an untreated comparison group. Findings from one product, technique or population cannot automatically be applied to everyone.
This means polynucleotides can be discussed as an option for suitable patients, but guaranteed collagen changes, dramatic lifting or a fixed duration of effect should not be promised. A balanced consultation should explain both the possible benefits and the uncertainty that remains.
Downtime between appointments
Redness, tenderness, swelling, bruising and small raised bumps at injection points can occur. These reactions often settle, but their severity and duration vary by person and treatment area. Delicate regions may look more swollen, and appointments should be planned with work, travel and important events in mind.
Follow the aftercare advice provided and contact the clinic promptly if pain, swelling, colour change or another symptom is severe, worsening or unexpected. Recovery from the previous session should also be considered before the next one proceeds.
Suitability comes before the schedule
Treatment may need to be avoided or postponed during pregnancy or breastfeeding, with active infection or inflammation, or when allergies, medical conditions, medicines or previous reactions require further review. Because products differ, their specific ingredients and contraindications must be checked rather than assuming all polynucleotides are interchangeable.
A consultation is therefore essential before committing to a course. It should confirm the concern being treated, establish realistic goals, discuss alternatives and risks, and leave room to stop or adapt the plan if the response is not appropriate for you.
