Skin quality. Individual attention.
Plinest is a family of polynucleotide treatments developed by Mastelli in Italy. The range uses PN-HPT polynucleotides for skin-quality goals, with different formulations and presentations for different areas. Your doctor confirms the exact product chosen for your plan.
We assess hydration, texture, elasticity and the concerns you would like to improve. Delicate eye-area treatment needs a different assessment from a broader facial plan. Our listed clinic options are Plinest Eye 1 ml at £349 and Plinest Face 2 ml at £449 per session.
Our practice focuses on collagen stimulators, skin-quality treatments and devices. Experience with Korean aesthetic protocols, careful anatomical planning and clear advice about product, amount and care help you feel informed before deciding on a Mastelli treatment.
We take time to understand what matters to you, review your health and previous treatments, and explain why an option may suit your needs. Your comfort and safety take priority over proceeding with treatment. You can ask questions, consider the alternatives and make your decision without pressure.
Your plan explains the agreed coverage, expected changes and care afterwards. We aim for a considered improvement that respects your natural anatomy, with a clear reason for every treatment we recommend.

Our clinic’s experience · Polynucleotide care
We offer the treatment options and prices above so you can make an informed comparison. For many suitable skin-quality concerns, our clinic usually recommends Rejuran: we have found its range useful when planning hydration, texture and selected scar care. This is our clinical preference, rather than a claim that one product is best for every patient.
Rejuran I is our preferred option for delicate eye-area skin where suitable; Rejuran S is frequently selected for broader skin-quality and texture concerns. Your anatomy, skin condition and previous response guide the choice.
Compare Rejuran products and prices →Dryness, fine lines, crepey texture and selected scars may need different formulations, coverage and appointment plans. We explain what the proposed treatment is intended to improve and how we will assess your progress.
If pigmentation or melasma is part of your concern, your doctor assesses the cause and may discuss a separate pigment-focused plan alongside skin-quality care. We also compare Juvelook when collagen support and skin thickness are a greater priority.

Mastelli’s range includes Plinest, Plinest Eye, Plinest Fast, Plinest One and other presentations. Formulations, concentrations, pack sizes and intended areas differ; they should not be treated as interchangeable simply because the names share Plinest.
PN-HPT refers to Mastelli’s high-purification polynucleotide technology. Polynucleotides are purified DNA fragments of fish origin used in these formulations for skin hydration and tissue-quality support. Tell your doctor about fish allergy and previous product reactions during consultation.
The photographs show genuine product presentations from our existing image library. Your doctor explains the specific formulation, clinic treatment amount and proposed coverage before starting. You can ask to see the packaging and discuss each part of the plan.
A plan for your skin
Discuss skin that looks dull or feels less supple, with selected texture and elasticity concerns. Your doctor confirms the formulation, distribution and coverage within the agreed 2 ml facial option.
The 1 ml eye option focuses on suitable skin-quality concerns following a careful assessment. We distinguish texture and hydration from hollowing, puffiness or other causes that may need a different approach.
Neck and other concerns can be discussed individually. Product choice, area, original quantity and price are confirmed separately rather than being assumed within a face or eye booking.
Different Plinest formulations have different roles. Your doctor assesses the concern, confirms the product and explains appropriate coverage. A skin-quality treatment should not be confused with automatically correcting every eye bag, deep hollow or structural contour concern.
A personal polynucleotide plan
A delicate eye area and broader facial skin have different needs. We explain the selected Mastelli product and why it fits the tissue and goal, rather than choosing by a product name alone.
The listed clinic option states the amount used at your appointment. A photographed retail pack or syringe may have a different total capacity, so we make your actual quantity and agreed price clear.
The number and spacing of sessions depend on the formulation, area and response. Your doctor explains a proposed course and its cost before treatment, with progress reviewed before further appointments.
Before. During. After.
Tell us what you would like to improve and bring details of earlier treatments, medicines, allergies and your home skincare. Your doctor assesses the skin, explains suitable options and agrees your plan before any treatment.
We prepare the area, discuss suitable numbing and select the technique for the formulation and treatment depth. Clear communication and comfort checks help you feel supported throughout the appointment.
Leave with guidance on skincare, activity and when to review your response. Your complimentary skincare routine advice focuses on a manageable routine, moisturising and sun protection suited to your skin.
Temporary small injection bumps, redness, swelling, tenderness or bruising can occur, particularly in delicate areas. Your doctor explains personal skincare, sun protection, activity and review guidance and how to contact the clinic for advice.
Plan. Treat. Review.
Your doctor reviews skin quality, earlier procedures, allergies, medicines and goals. We discuss suitable options and confirm the exact formulation and original quantity before you decide.
Suitable Korean topical numbing where appropriate, careful technique and regular comfort checks help you feel supported. The technique is chosen for the product and area, with time to pause and ask questions.
Skin-quality changes develop gradually over weeks. Personal aftercare and complimentary skincare routine advice support your next steps, while review guides any further sessions or maintenance.

Trustpilot · Aya.T · Dr Eroglu changed my life, honestly. I had a dent from a bad steroid shot on the side of my face and he advised me appropriately and gave me a Lenisna PDLLA Injection. Within 6 months I had my life back, my confidence back and I am forever grateful. He knows what he is doing, and he is a great doctor and practitioner. I will be back soon to try a new treatment – maybe the Rejuran for my neck lines. Thank you Dr, you gave my confidence back and I am forever grateful <3
