Skincare – Polynucleotides Explained: Debunking Common Misconceptions
This is a collaborative post.
The world of beauty and skincare is ever-evolving, with new treatments and technologies emerging constantly. One treatment that’s been making waves is the polynucleotide treatment, more popularly known as the salmon sperm facial. Despite its rise in popularity, particularly among celebrities like Jennifer Aniston, this treatment is surrounded by numerous myths and misconceptions.

What Are Polynucleotides?
Polynucleotides are naturally occurring molecules made up of long chains of nucleotides, which are found in all living cells. In simple terms, they are essential biological building blocks that play a role in cell repair and regeneration. Because they already exist in the body, polynucleotides are very well tolerated by the skin, making them a popular ingredient in advanced skincare and aesthetic treatments.
In skincare, polynucleotides are valued for their ability to support skin health rather than just mask surface concerns. They work beneath the surface to improve hydration, strengthen the skin barrier, and create the right conditions for cell renewal. This makes them especially helpful for skin that is stressed, dehydrated, or showing early signs of ageing, as they focus on restoring balance and resilience.
What makes polynucleotides stand out is their gentle, regenerative approach. Instead of forcing rapid changes, they encourage the skin to repair and improve itself gradually. The result is healthier-looking skin with better texture, elasticity, and glow over time. This natural, skin-first approach is why polynucleotides are often described as “skin quality boosters” rather than quick-fix treatments.
How Do Polynucleotides Work?
Polynucleotides work in skincare by supporting the skin’s natural repair and renewal processes from the inside out. They are made up of chains of tiny molecules that are naturally found in our bodies, which means the skin recognises them easily. Once applied or injected in aesthetic treatments, polynucleotides help create an ideal environment for skin cells to function better, encouraging healthier, more resilient skin.
One of the key ways polynucleotides help the skin is through hydration and repair. They have a strong ability to bind water, which helps improve moisture levels and gives skin a plumper, smoother appearance. At the same time, they support damaged cells by protecting them from stress and encouraging regeneration. This makes them especially useful for tired, dull, or compromised skin that needs a gentle boost rather than harsh stimulation.
Polynucleotides also work by improving overall skin quality over time rather than delivering instant, artificial-looking results. They help stimulate fibroblasts, the cells responsible for producing collagen and elastin, which leads to firmer, more elastic skin gradually. Because they work with the skin’s own biology, the results tend to look natural, making polynucleotides a popular choice for people looking to restore skin health, glow, and long-term strength.
Debunking Common Myths About Salmon Sperm Facials
Despite their benefits, polynucleotide treatments are often misunderstood. Let’s address some of the most common myths:
- Myth 1: This Treatment Involves Salmon Sperm Directly to the Face
One of the most prevalent misconceptions is that the treatment involves directly applying salmon sperm to the skin. This is not the case. The active ingredient in these facials is derived from purified fragments of salmon DNA originally taken from sperm.
- Myth 2: Polynucleotides Are Highly Expensive and Exclusive for Celebrities and the Elite
While it’s true that some high-end skincare treatments can be costly, polynucleotide facials are becoming more accessible. The cost varies depending on the clinic and the specific treatment plan, but they are not exclusively reserved for celebrities or the elite. Many clinics offer affordable packages to make this advanced skincare option available to a broader audience.
- Myth 3: Polynucleotides Smell Like Fish
Another common concern is the potential for an unpleasant odour. Since the polynucleotides are derived from salmon DNA, some might worry about a fishy smell. However, the purification process ensures that there is no odour, making the treatment experience pleasant and odour-free.
- Myth 4: Salmon Sperm Facials Are Painful
The idea of a facial involving any form of injection can be daunting, but polynucleotide treatments are designed to be minimally invasive and relatively painless. The procedure typically involves micro-needling, which creates tiny punctures in the skin to allow better absorption of the polynucleotides. Most patients only experience mild discomfort, if any.
- Myth 5: They Are Just for Use on the Face
While the term “facial” suggests facial application, polynucleotide treatments are versatile and can be used on various parts of the body. Common areas include the neck, décolletage, and hands. The regenerative properties of polynucleotides can benefit any area of the skin that needs rejuvenation.
Who Should Avoid Polynucleotide Treatments?
Despite their many benefits, polynucleotide treatments are not suitable for everyone. Because these treatments harness the transformative properties of salmon DNA, they are not suitable for people with fish allergies. Additionally, they are not considered vegan or vegetarian.
As with most medical cosmetic procedures, certain groups should avoid polynucleotide treatments:
- Individuals under the age of 18
- Pregnant or breastfeeding women
The Science Behind Polynucleotide Success
Polynucleotide treatments leverage the natural regenerative properties found in salmon DNA. These DNA fragments work at a cellular level to repair and rejuvenate the skin, promoting collagen production and enhancing skin hydration. This scientific approach to skincare offers a natural alternative to traditional fillers and injectables.
Conclusion
Polynucleotide treatments, often named salmon sperm facials, are a scientifically backed skincare treatment that offers a range of benefits from reducing fine lines to hydrating the skin. Whether you’re looking to revitalise your skin or target specific problem areas, a polynucleotide facial could be your solution.
For those considering this treatment, it’s important to consult with a qualified aesthetic professional to determine if it’s the right fit for your skin type and concerns. Always prioritise treatments that are safe, effective, and suited to your individual needs.
