Skin Boosters vs Polynucleotides

What’s the Difference?

In the world of aesthetic medicine, new treatments emerge constantly each claiming to deliver better hydration, smoother texture, or a more youthful glow. Two of the most talked-about options today are skin boosters and polynucleotides. Though both aim to rejuvenate the skin, they work in very different ways. Understanding the distinction can help clients choose the treatment that best suits their needs.

What Are Skin Boosters?

Skin boosters are injectable treatments made primarily of hyaluronic acid (HA) a molecule naturally found in the skin that attracts and holds moisture. Unlike dermal fillers, which use thicker HA gels to add structure or volume, skin boosters are very thin and soft.

How They Work

Skin boosters hydrate the skin from within. Once injected, they:

• Improve skin hydration

• Boost elasticity

• Enhance smoothness and luminosity

• Reduce fine crepey lines

They do not change facial shape or add volume, instead they create a healthy, plump, dewy complexion.

Best For:

• Dry or dull skin

• Fine lines (especially around mouth, eyes, or cheeks)

• Younger clients seeking prevention

• Anyone wanting a more refreshed look without structural changes

What Are Polynucleotides?

Polynucleotides are bio-stimulating injectables derived from purified DNA fragments (commonly salmon or trout DNA, although highly refined and sterile).

Unlike HA-based skin boosters, polynucleotides are not moisturizers. Instead, they act as cellular messengers, triggering the skin’s natural repair mechanisms.

How They Work

Polynucleotides stimulate fibroblasts, the cells responsible for producing collagen and elastin. Their effects include:

• Enhanced tissue regeneration

• Improved skin firmness and elasticity

• Reduced inflammation and redness

• Strengthening of the skin barrier

• Long-term improvement to texture, wrinkles, and overall quality

Polynucleotides don’t offer an immediate “glow” like HA does. Their results appear gradually as the skin regenerates over a period of time from a course of treatments.

Best For:

• Ageing or thinning skin

• Acne scarring

• Inflammation, rosacea-prone skin, or compromised skin barriers

• Under-eye rejuvenation

• Clients wanting long-term strengthening of the skin
