As the body’s largest organ, the skin is a vital barrier against environmental stressors while maintaining hydration, temperature regulation, and overall health. However, with age, the skin undergoes structural changes: collagen depletion, reduced elasticity, and slower cellular renewal—leading to visible signs of aging and increased sensitivity.
Mastelli, an Italian pharmaceutical company, has pioneered regenerative medicine. With decades of expertise in biotechnology and tissue repair, Mastelli focuses on developing innovative solutions that restore the skin’s vitality at a cellular level. One of its most notable contributions is Plinest, a polynucleotide-based injectable designed for long-term rejuvenation. Backed by scientific research and clinical application, Plinest exemplifies Mastelli’s commitment to advancing safe, effective treatments that support skin health and aesthetic enhancement.
This article will explore Mastelli’s legacy, the science behind Plinest, and its impact on modern aesthetic medicine.

Mastelli’s History and Expertise in Aesthetic Medicine
Founded in 1952, Mastelli has established itself as a pioneer in regenerative medicine and aesthetic dermatology. Headquartered in Italy, the company has specialized in developing polynucleotide-based treatments and has created Class III medical devices designed for skin rejuvenation and anti-aging solutions.
Over the decades, Mastelli has refined its expertise in crafting intradermal revitalizers, with product lines such as PLINEST® and NEWEST®. These products combine Polynucleotides with Hyaluronic Acid to enhance skin repair, hydration, and elasticity.
Mastelli roots its innovation in a strong commitment to biocompatibility and cellular regeneration. Their proprietary PN-HPT (Polynucleotides High Purification Technology) ensures the delivery of highly purified DNA fragments that actively support tissue repair while minimizing the risk of adverse reactions. The company designs formulations to address common aging concerns while actively promoting natural skin renewal, positioning Mastelli as a leader in regenerative aesthetics.
With a strong emphasis on research, safety, and clinical efficacy, Mastelli continues to evolve its product portfolio, providing cutting-edge solutions that uphold the highest quality standards for medical professionals and patients worldwide.
Innovation Behind Plinest by Mastelli
For those asking, what is Plinest?—it is Mastelli’s flagship injectable treatment developed to support natural skin regeneration through polynucleotide-based biostimulation. Plinest utilizes PN-HPT technology to deliver highly purified polynucleotides derived from trout DNA, designed to activate fibroblasts, thereby enhancing collagen and elastin production. This process significantly improves skin texture, hydration, and firmness, offering a gradual and natural rejuvenation effect.

Key attributes that differentiate Plinest:
- PN-HPT Technology: Extracted from natural DNA sources and purified for optimal compatibility with human skin.
- Cellular Stimulation: Encourages fibroblast activity and extracellular matrix remodeling.
- Hydration and Elasticity: Improves skin texture, thickness, and elasticity over time.
- Non-Crosslinked Formulation: Ensures a more natural integration with tissue, minimizing the risk of nodules or overcorrection.
- Safe Profile: Designed with minimal additives, reducing the risk of hypersensitivity or adverse reactions.
Unlike conventional dermal fillers, Plinest’s regenerative mechanism makes it an ideal solution for treating fine lines, acne scars, skin laxity, and photoaging, providing long-term skin health improvements rather than temporary cosmetic effects.
Global Reach and Regulatory Compliance of Mastelli Plinest
Mastelli’s impact extends well beyond its Italian roots, with a global presence in over 40 countries. This widespread adoption reflects not only the efficacy of its products but also its dedication to stringent regulatory compliance and quality assurance.
