Mastelli is a recognized Italian pharmaceutical company with a history dating back to 1952. Over the decades, Mastelli has established itself as a global player in developing innovative therapies, particularly in polynucleotide-based skin regeneration. Their commitment to scientific research and product quality has positioned them at the forefront of aesthetic medicine, offering solutions that emphasize both safety and natural-looking results.
One of Mastelli’s most notable innovations is Plinest, a dermal injectable that utilizes highly purified polynucleotides derived from natural sources. Unlike traditional fillers, Plinest stimulates the body’s collagen and elastin production, promoting improved skin hydration, elasticity, and overall rejuvenation. This minimally invasive treatment enhances skin texture while also helping protect skin cells from oxidative stress, offering a comprehensive approach to facial and body revitalization.

The History and Innovation Journey of Mastelli and Plinest

Mastelli has been a trailblazer in biopharmaceutical innovation since its founding in 1952 in Sanremo, Italy. With a longstanding focus on dermatology, wound healing, aesthetic medicine, and regenerative therapies, the company has continuously contributed to advancing skin treatment technologies that blend science with patient-centered care.
One of Mastelli’s most notable contributions is its polynucleotide-HPT (High-Purification Technology)—a proprietary method that ensures the highest purity and biocompatibility of polynucleotides for medical use. This groundbreaking innovation ultimately led to the development of Mastelli’s Plinest, a product that has since defined a new standard in non-surgical facial rejuvenation.
Key milestones in Mastelli’s development include:
- 1952: Mastelli is established, specializing in pharmaceutical and dermatological solutions.
- 1980s: Research into polynucleotides and their regenerative potential begins.
- 2005: Plinest is introduced as the first polynucleotide-based aesthetic injectable.
- Present: Mastelli continues refining its proprietary technology and expanding its global presence in regenerative medicine.
Scientific Research and Clinical Evidence Supporting Plinest

Mastelli offers Plinest and its related innovations across Italy and various global markets. Using PN‑HPT®, this injectable delivers highly purified trout-derived polynucleotides that activate fibroblasts, boost collagen production, and enhance skin hydration—collectively improving skin elasticity, radiance, and structure.
If you’ve ever wondered what is Plinest, it is an injectable biostimulatory treatment that does not simply fill lines, but instead works at a cellular level to rejuvenate and repair the skin.
A study by Araco, Araco, & Raichi (2022) found that PN‑HPT® significantly improved skin texture and the appearance of nasolabial folds, particularly in patients with moderate to severe facial aging. Moreover, it showed potential for prolonging the effects of cross-linked hyaluronic acid treatments, offering more comprehensive and lasting outcomes.
That said, more clinical trials and regulatory approvals are still needed—especially for U.S. markets. Once FDA approval is secured, Mastelli’s reach could expand significantly. When this happens, they could bring Plinest to even more patients seeking safe and effective skin rejuvenation.
Manufacturing Standards and Quality Control Behind Plinest

Practitioners often ask, “What is Plinest and how is it made?” As a member of Farmindustria, the Association of Italian Pharmaceutical Industries, Mastelli adheres to Good Manufacturing Practices (cGMP) and enforces stringent quality control standards at every stage of production.
Plinest’s development leverages advanced purification technologies that minimize contaminants, improve biocompatibility, and ensure consistent product performance. The use of High-Purification Technology ensures that every vial meets exacting quality benchmarks.
Regular audits, process validation, and batch testing maintain safety and product integrity, aligning with both European and international pharmaceutical standards. These controls are critical for maintaining patient trust and clinical reliability.
Expanding the Mastelli Portfolio Beyond Plinest
While Plinest remains the company’s flagship product, Mastelli continues to evolve its portfolio of aesthetic and regenerative medicine. In addition to Plinest, the company offers:
- Plinest Fast: For rapid rejuvenation
- Plinest Eye: Targeting delicate periocular skin
- Plinest Hair: Stimulating scalp vitality and follicle health
These formulations use the same polynucleotide technology but are optimized for targeted applications, ensuring clinicians can customize treatment for eyes, scalp, and facial skin. Each formulation reflects Mastelli’s focus on minimally invasive, high-efficacy approaches to aesthetic care.
Continuous R&D ensures the brand remains at the forefront of the global regenerative aesthetic market. The company aims to provide clinicians with a scientifically grounded and results-driven product line that meets evolving patient expectations.
