Key Takeaways
- Different types of skin boosters support different aspects of skin quality and should not be treated as interchangeable.
- Hyaluronic acid (HA) skin boosters are generally used when hydration and tissue suppleness are the main concerns.
- Polynucleotide (PN) skin boosters may be considered when greater emphasis is placed on dermal repair, resilience and skin recovery.
- Treatment choice depends on the specific formulation, treatment indication, anatomical area, skin thickness, medical history and previous treatment response.
- Aesthetic clinics may sometimes use HA- and PN-based injectables at different stages of a broader treatment plan, provided that each treatment has a clear indication.
Introduction
Skin boosters are often grouped under a single treatment category, but different formulations support different aspects of skin quality. This means choosing between different types of skin boosters depends less on the treatment category and more on the condition of the skin being treated.
At AEON Medical & Aesthetic Centre, we therefore start by identifying what is contributing to the skin concern. Dehydration may present as roughness, reduced suppleness, or more visible fine lines, while thin skin, fine lines and uneven texture may require a different approach from dryness alone. The appropriate treatment depends on the anatomical area, underlying cause and specific injectable formulation.
Below, we distinguish between HA and PN skin boosters and the factors we consider when deciding which treatment may be more appropriate for your skin.
What Are HA Skin Boosters?
HA is a naturally occurring glycosaminoglycan found in the skin and extracellular matrix. Injectable HA products intended for skin quality may improve hydration, suppleness and the appearance of selected fine lines. Their behaviour depends on factors such as HA concentration, molecular weight, cross-linking or stabilisation method and injection technique. When introduced into the dermis, HA skin boosters can help increase tissue hydration, support suppleness, and reduce the appearance of fine lines associated with dryness.
Our doctors will therefore recommend this type of skin booster when concerns include:
- Dry or rough-feeling skin
- Reduced suppleness
- Fine lines that become more noticeable with dehydration
However, not all HA formulations behave in the same way. At AEON, our hybrid HA formulations combine high- and low-molecular-weight HA within a stabilised complex. It is designed to disperse through the treated tissue and is used primarily for skin hydration and tissue quality rather than focal volumisation or structural contouring.
After injection, these formulations can diffuse through the treated tissue and may also support biological processes associated with collagen and elastin remodelling.
Depending on the particular HA formulation and injection protocol, common treatment areas may include the face, neck, décolletage or hands. Treatment near the eyes, however, will require a formulation and technique that is specifically suited to the area. The thin skin around the eyes and lymphatic drainage can increase the risk of visible product or prolonged swelling.
What Are PN Skin Boosters?
PN skin boosters contain purified chains of nucleotides, commonly obtained from fish-derived DNA sources. They have been studied for their potential to improve measures such as skin hydration, elasticity, texture and the appearance of fine lines.
Proposed mechanisms include effects on fibroblast activity and the extracellular environment. Outcomes vary according to the formulation, treatment area and individual response.
We consider PN skin boosters where the skin is:
- Thin or delicate
- Uneven in texture
- Showing persistent textural or skin-quality concerns after the skin has fully recovered from a previous procedure
- Affected by selected types of acne scarring
Elective injections are generally deferred where active inflammation, dermatitis, infection or incomplete healing is present.
Common treatment areas include the face, neck and selected under-eye areas. PN may also be considered as an adjunct where general skin quality is a concern, but established acne scars usually require scar-directed assessment and may need treatments such as subcision, microneedling, RF microneedling or laser procedures, depending on scar type.
How Do We Decide Which Skin Booster Suits Your Skin?
At AEON, we choose between the two types of skin boosters based on the skin concern being treated and the support the tissue needs.
In short, while HA skin boosters primarily restore tissue hydration and surface suppleness through water retention, PN skin boosters focus on supporting cellular repair, collagen remodelling, and dermal resilience.
| HA may be considered when… | PN may be considered when… |
| Hydration or reduced suppleness is the main concern | Fine lines, reduced elasticity, or uneven texture are among the concerns |
| The selected HA formulation is appropriate for the treatment area | The selected PN formulation is appropriate for the treatment area |
| A broadly distributed skin-quality effect is intended rather than focal volume | Improvement in general skin quality is intended rather than focal volume |
| The patient has no contraindication to the proposed HA product | The patient has no contraindication to the proposed PN product or its source |
Other considerations include:
- Product and formulation: Composition, concentration, rheological properties and intended treatment area.
- Treatment area and anatomy: Particularly around the eyes, where thin skin and lymphatic drainage can increase swelling or product visibility.
- Skin condition: Including dryness, fine lines, elasticity, active inflammation and scarring.
- Medical and treatment history: Previous injectable response, allergies, medications and tendency to bruise or swell.
- Treatment goals: Whether the priority is hydration, texture, elasticity or another defined concern
In some cases, one formulation may be sufficient. Where more than one skin-quality concern is present, HA and PN treatments may be considered at separate stages. Combining them is not automatically necessary or more effective, and the sequence should be based on the treatment area, formulation and response.
What Can You Expect After Skin Booster Treatment?
Small raised injection marks, sometimes described as papules or bumps, can occur after skin booster treatment because the formulation is placed within the dermis. These marks are usually temporary and often settle into the surrounding tissue within 24 to 72 hours, although this can vary with skin thickness, treatment area, injection technique, and the formulation used.
Mild swelling may also improve over several days, while bruising can remain visible for one to two weeks or occasionally longer.
Less common complications can include infection, persistent swelling, inflammatory reactions, nodules, asymmetry or visible product. As with other injectable treatments, vascular compromise is rare but potentially serious. Product-specific allergies and contraindications should be reviewed before treatment.
Patients are advised to seek review for:
- Increasing pain
- Blanching or unusual skin discolouration
- Worsening swelling or redness
- Visual symptoms
- Signs of infection
Frequently Asked Questions
Q: Can HA and PN skin boosters be combined in one treatment plan?
Yes. When skin presents with both dehydration and reduced dermal thickness, doctors may sequence HA and PN treatments at different intervals to address tissue suppleness and structural repair concurrently.
Q: How do doctors determine whether my skin needs HA or PN?
Treatment selection is guided by clinical assessment and diagnostic imaging (such as VISIA), which evaluate epidermal moisture levels, skin thickness, barrier resilience, and underlying tissue quality.
Q: Are skin booster results permanent?
No. Because skin boosters integrate into the tissue and undergo natural metabolic breakdown over time, maintenance sessions tailored to individual skin turnover and aging rates are typically recommended.
Conclusion
HA- and PN-based injectables are not interchangeable, but their potential effects may overlap. HA-based treatments are commonly considered when hydration and suppleness are the main priorities, while PN treatments have been studied for possible improvements in hydration, elasticity, texture and fine lines. The choice between different types of skin boosters should be based on the specific product, treatment area, clinical findings and individual goals.
At AEON Medical & Aesthetic Centre, Dr Jeslin Wong assesses these factors during consultation. VISIA imaging may be used where appropriate to document visible features such as pigmentation, pores and surface texture, and to provide a consistent photographic reference over time.
