Injectable treatment supporting skin quality

What is a polynucleotide treatment?

Polynucleotide treatment is an injectable treatment intended to support hydration, elasticity and surface quality. It is not the same as dermal filler and is not primarily used to add facial volume.

01

What are polynucleotides?

Polynucleotide products contain purified DNA fragments. BeautyBell lists Plinest, Plinest Fast and the eye-area product Plinest Eye.

PDRN is sometimes used in marketing, but PN and PDRN are not interchangeable in every product or study. The exact product is discussed at the appointment.

02

What is the aim?

The aim may be to support hydration, elasticity and skin texture. Results develop gradually and vary.

Evidence in aesthetic use remains limited and treatment methods vary, so BeautyBell does not promise DNA repair, regeneration or a specific increase in collagen.

03

How is treatment planned?

The area, goal, health information, allergies and tendency to swell are reviewed first.

BeautyBell’s current plan commonly lists a series of three sessions at 2–4 week intervals, adjusted individually.

04

Recovery and safety

Temporary redness, swelling, tenderness, small bumps or bruising may occur.

Active infection or inflammation prevents treatment. Pregnancy, breastfeeding, fish allergy, medication and health conditions are reviewed beforehand.

Frequently asked questions

Clear answers to common questions

Do polynucleotides add facial volume?

Their main aim is to support skin quality, not to reshape the face like filler. Temporary swelling can occur.

When can results be assessed?

Changes develop gradually and are assessed after recovery and the planned series. A fixed result cannot be promised.

How do the Plinest products differ?

They are intended for different areas and goals. Plinest Eye is the eye-area option; the product is selected after assessment.

Does fish allergy matter?

Yes. Disclose fish and other allergies so product suitability can be assessed.
