Types of Skin Boosters: PLLA, PLA, PDRN, and Exosomes – Which Is Right for Your Patients?

Understanding Skin Boosters: What Are They and How Do They Work?

Most skin booster products are classified as cosmetics due to their complex ingredient profiles, making medical device or pharmaceutical approval difficult. However, manufacturers develop these products with the knowledge that they are often used in injectable treatments, ensuring the highest purity and safety standards. While we do not condone or encourage the off-label use of these products as injections, it is a common practice among aesthetic professionals, and this article only provides factual information about their usage.

Skin boosters have gained significant traction in aesthetic medicine as an effective way to improve skin texture, elasticity, and hydration. Unlike dermal fillers, which primarily restore volume, skin boosters work at a cellular level to enhance skin quality.

But wait, let me tell you something—not all skin boosters are the same. The four primary categories include PLLA (Poly-L-Lactic Acid), PLA (Polylactic Acid), PDRN (Polydeoxyribonucleotide), and Exosomes. Each has unique benefits, making the choice highly dependent on the patient’s skin condition, age, and treatment goals.

PLLA (Poly-L-Lactic Acid) Skin Boosters

PLLA-based skin boosters work by stimulating collagen production over time, leading to progressive skin thickening and elasticity improvement. Rather than filling wrinkles immediately, PLLA treatments gradually rebuild skin structure, making them an excellent choice for patients with volume loss and severe skin laxity.

How Does PLLA Work?

PLLA acts as a biostimulator, triggering fibroblasts to produce new collagen fibers. This process enhances skin firmness and elasticity over several months.

Popular PLLA Skin Boosters

  • Aesthefill – A well-known Korean PLLA-based booster designed for deep skin rejuvenation and long-term collagen stimulation.

Best Candidates for PLLA-Based Boosters

  • Patients with moderate to severe skin laxity.
  • Individuals looking for long-term anti-aging solutions.
  • Those who want to increase skin thickness without adding volume.

Key Advantages of PLLA Skin Boosters

✔️ Gradual and natural skin improvement.

✔️ Long-lasting effects (up to 24 months).

✔️ Enhances overall skin density and firmness.

PLA (Polylactic Acid) Skin Boosters

PLA-based skin boosters are similar to PLLA but often have a slightly different breakdown rate. They provide gradual collagen regeneration while offering hydration and improving skin texture.

How Does PLA Differ from PLLA?

While both stimulate collagen, PLA is often used for fine lines, skin texture improvement, and more superficial rejuvenation compared to PLLA, which is preferred for deeper structural support.

Popular PLA-Based Skin Boosters

  • Etrebelle – A next-generation PLA-based biostimulator offering long-lasting results with smoother particle distribution.

Who Benefits Most from PLA Skin Boosters?

  • Younger patients who want preventative anti-aging treatments.
  • Patients with early signs of skin aging (fine lines and mild laxity).
  • Those who prefer mild collagen stimulation with hydration.

Key Advantages of PLA Skin Boosters

✔️ Provides a subtle lifting effect.

✔️ Hydrates and improves skin elasticity.

✔️ Ideal for preventative aging treatments.

PDRN (Polydeoxyribonucleotide) Skin Boosters

PDRN, commonly known as salmon DNA, is one of the most recognized skin regeneration treatments. Unlike PLLA or PLA, which stimulate collagen, PDRN repairs and rejuvenates damaged skin cells at a DNA level.

The Relationship Between PDRN and PN (Polynucleotide) in Skin Rejuvenation

PDRN (Polydeoxyribonucleotide) and PN (Polynucleotide) are often used interchangeably in the aesthetic industry, but there are some differences worth noting. PDRN is a specific type of PN, derived from salmon DNA fragments, while PN refers to the broader category of nucleotides that stimulate cell repair and regeneration. Both are known for their ability to activate fibroblasts, enhance wound healing, and improve skin elasticity.

The primary distinction lies in molecular structure and function. While PDRN is composed of smaller DNA fragments that primarily work on repairing damaged skin and reducing inflammation, broader PN formulations often contain higher molecular weight polynucleotides, which can improve hydration, elasticity, and long-term skin regeneration. This makes PN-based products ideal for progressive anti-aging treatments, whereas PDRN is often favored for post-procedure healing and sensitive skin rejuvenation.

How Does PDRN Work?

PDRN promotes tissue repair and healing, accelerating cell regeneration and increasing skin elasticity. It is often used for post-laser recovery, acne scarring, and general skin revitalization.

Popular PDRN-Based Skin Boosters

  • Rejuran Healer – One of the most popular PDRN injectables in Korea, known for skin healing, hydration, and elasticity restoration.
  • Rejuran Tone-Up – A PDRN-based product that brightens dull skin and improves overall skin quality.

Who Should Use PDRN Skin Boosters?

  • Patients with damaged or thinning skin.
  • Those dealing with post-inflammatory pigmentation or acne scars.
  • Individuals seeking fast healing and improved skin resilience.

Key Advantages of PDRN Skin Boosters

✔️ Speeds up skin recovery and healing.

✔️ Boosts hydration and skin repair.

✔️ Suitable for sensitive and damaged skin types.

Exosome Skin Boosters: The Future of Regenerative Skincare

Exosome-based skin boosters are the latest innovation in regenerative aesthetics. Exosomes are extracellular vesicles derived from stem cells, packed with growth factors, proteins, and genetic material that promote skin renewal and repair.

How Do Exosome Skin Boosters Work?

Exosomes act as cell messengers, improving collagen synthesis, reducing inflammation, and accelerating skin healing. Unlike PLLA, PLA, or PDRN, exosomes communicate directly with skin cells, ensuring a more advanced approach to skin rejuvenation.

Popular Exosome Skin Boosters

  • ASCE+ – A cutting-edge exosome-based skin booster enhancing skin regeneration, hydration, and repair.
  • Exoxe – Known for targeting aging concerns and improving overall skin texture.

Who Should Consider Exosome Skin Boosters?

  • Patients seeking rapid skin recovery and rejuvenation.
  • Individuals looking for cutting-edge anti-aging solutions.
  • Those interested in non-invasive skin regeneration therapy.

Key Advantages of Exosome Skin Boosters

✔️ Advanced skin renewal therapy.

✔️ Enhances cell-to-cell communication for better skin function.

✔️ Improves skin tone, texture, and hydration.
