Polynucleotides vs. Other Skin Boosters

Whilst the temperature drops further and our skin feels tighter and duller, we’re all looking for a healthy boost to add back into our skin. In this blog, we’ll discuss the difference between Polynucleotides vs skin boosters, to allow you to make the right choice for your skin needs.

What Are Polynucleotides?

Polynucleotides are injectable biostimulators derived from purified fish DNA (often salmon DNA) that work to repair and rejuvenate the skin from within. Highly compatible with human DNA, they safely trigger fibroblast activity to boost collagen and elastin production, improving elasticity and reducing visible signs of ageing. With additional antioxidant and hydrating benefits, Polynucleotides help restore healthier, smoother, and more radiant skin.

Rather than simply filling or hydrating, Polynucleotides repair and restore at a cellular level, making them an advanced option for long term skin rejuvenation.

The Science Behind Polynucleotides

Polynucleotides work by supporting your skin at a cellular level; helping it to repair, regenerate, and renew itself naturally. These innovative injectables contain highly purified DNA fragments that, once introduced into the skin, signal your body’s own cells to begin healing and rebuilding.

Here’s the science bit: Polynucleotides act as ‘bio-stimulators’, meaning they activate fibroblasts: the skin cells responsible for producing collagen, elastin, and hyaluronic acid. This renewed activity helps to strengthen the skin’s structure, improve elasticity, and restore firmness. At the same time, they enhance microcirculation and reduce oxidative stress, providing antioxidant protection and promoting a brighter, more even complexion.

In simple terms, Polynucleotides don’t just hydrate or fill the skin, they encourage it to function like younger, healthier skin again. The result? A smoother, firmer, and naturally revitalised complexion that continues to improve over time. This treatment is perfect for tired, dull or sun-damaged skin in need of repair and rejuvenation. Take a look at our blog ‘Understanding Polynucleotide Injections: The Science Behind Skin Rejuvenation’ for a more in-depth look.

Treatment Areas

Polynucleotide treatments are incredibly versatile and can be used across multiple areas to rejuvenate and restore the skin’s natural health. Common treatment zones include the face, neck, under-eye area, décolletage, and hands: all areas that typically show early signs of ageing or dehydration.

They’re especially effective for thin, crepey, or sun-damaged skin, where loss of elasticity and dullness are most noticeable. The under-eye area, in particular, responds beautifully to Polynucleotides, helping to reduce fine lines, puffiness, and dark circles by improving microcirculation and skin firmness.

Because of their regenerative and healing properties, Polynucleotides are also an excellent option for post-procedure recovery, such as after laser treatments, microneedling, or chemical peels. They help calm inflammation, repair the skin barrier, and accelerate tissue renewal: leaving the skin smoother, stronger, and more radiant overall.

Popular Skin Booster Alternatives

• Profhilo

Profhilo is a hyaluronic acid based injectable treatment that deeply hydrates dry and dull skin through a process of ‘bio-remodelling’. This process works by stimulating collagen and elastin production through a high concentration of hyaluronic acid injected into the skin. This treatment is used to improve elasticity and firmness without adding volume to the skin, with effects typically lasting around 6 months.

• Seventy Hyal 2000

Seventy Hyal 2000 is a newer-generation skin boosting treatment that focuses on hydration and glow. This bio-stimulating product contains one of the highest molecular weight hyaluronic acid formulations of skin boosters, which helps with intense moisture retention and nourishment deep within the skin surface. This treatment is best for younger skin or first-time injectable patients and lasts around 6 – 12 months.

• Sunekos

This treatment combines amino acids with hyaluronic acis to stimulate collagen and elastin production, helping regenerate the skin from within. Sunekos helps increase hydration, elasticity and overall skin health making it a great option for fine lines and delicate areas such as the under eye, décolletage and neck. This treatment requires around 3 – 4 sessions for results to show.

Polynucleotides vs. Other Boosters: Key Differences

(And why many patients now search for “Polynucleotides vs skin boosters” when choosing a treatment.)

Choosing the Right Treatment for You

Your skin’s needs are as individual as you are, and the right treatment depends on what you’re hoping to achieve. When comparing Polynucleotides vs skin boosters, Polynucleotides work beneath the surface to heal, regenerate, and strengthen the skin over time; making them ideal for restoring elasticity and improving texture. Meanwhile, traditional skin boosters deliver instant hydration and glow; perfect for a quick refresh or special occasion.

Understanding the difference helps you choose a treatment that truly aligns with your skin goals and lifestyle.

Polynucleotides may be best for you if:

• You’re noticing a loss of firmness, fine lines or early signs of sagging
• You’re wanting to heal and regenerate the skin rather than simply adding hydration back into the skin
• You have sensitive, sun-damaged or acne-prone skin

Other skin boosters may be best if:

• You’re looking for an instant glow or moisture boost before an event
• You’re new to injectables and looking for a subtle introduction
• You’d like smoother and more radiant skin with minimal downtime
