Polynucleotides

Educational reading for licensed practitioners — not clinical or injection guidance.
The face is often well maintained while the neck, chest and hands quietly give age away. These areas share three features that make them hard to treat and revealing when neglected: the skin is thin, it takes decades of unprotected sun, and it is in constant motion. Crepiness here is a problem of skin quality rather than lost volume, which is exactly the brief polynucleotides are built for.
Why These Areas Behave Differently
Neck, décolletage and dorsal hand skin has fewer oil glands, a thinner dermis and less supporting fat than the cheek. That means it dehydrates and creases more readily, shows sun damage sooner, and recovers more slowly from any intervention. Aggressive volumising or heavy filler is usually the wrong instinct: it can look unnatural over a mobile neck or a bony hand. What these zones respond to is an improvement in the condition of the skin itself — firmness, elasticity, hydration and texture.
Polynucleotides address that directly. Rather than adding bulk, they support the skin's own repair machinery: stimulating fibroblasts, improving the tissue's ability to hold water, and exerting antioxidant and anti-inflammatory effects across a course of treatment.
The Neck
The neck shows two overlapping issues — horizontal "necklace" lines and a general loss of firmness and crepiness. Polynucleotides target the second: a series of superficial micro-injections or nappage across the treatment area aims to thicken and firm thin skin over time. Ranges such as Plinest and Newest are commonly used here, with results developing gradually over the weeks after a completed course. Set expectations honestly — deep, established necklace creases are structural and may need a combination approach; polynucleotides improve the surrounding skin quality rather than erasing a fixed line.
The Décolletage
The chest is a classic sun-damage zone: fine vertical creases (often sleep-related), crepiness and uneven tone from years of UV exposure. Because décolletage skin is thin and slow to heal, a conservative, well-spaced protocol matters more here than elsewhere. Polynucleotides suit the area's need for regeneration over volume, and pair naturally with diligent daily sun protection — without which any gains are undermined. Formulations positioned for body and larger regenerative fields, such as Newest One and the collagen-polynucleotide Nithya Body, are relevant options for practitioners planning a chest course.
The Hands
Hand rejuvenation has two separate components that are easy to confuse. One is volume — the loss of fat that exposes tendons and veins, which is addressed with fillers or biostimulators. The other is skin quality — the thin, crepey, sun-spotted surface of the back of the hand. Polynucleotides speak to the second, supporting hydration and texture of the dorsal skin. They can sit alongside a volumising plan rather than replacing it.
The hands do carry particular practical cautions: the skin moves constantly, prominent veins and tendons sit close to the surface, and bruising is more likely. Careful technique and realistic aftercare counselling are essential.
Practical Points and Aftercare
- Course, not a single visit. These areas are typically treated over a short series of sessions spaced two to three weeks apart, with maintenance later in the year.
- Slower recovery. Expect redness, small papules at injection points and occasional bruising; off-face skin can take a little longer to settle than the cheek.
- Sun protection is non-negotiable. UV is the primary driver of damage in all three zones; ongoing SPF protects the investment.
- Fish-allergy screening. Most polynucleotides are derived from fish DNA, so a fish-allergy history is a key part of assessment.
As with the rest of this category, no injectable polynucleotide is FDA-approved; these are CE-marked products used internationally, and outcomes are gradual and individually variable rather than guaranteed.
The Takeaway
The neck, chest and hands age as skin-quality problems, not volume problems, which is why polynucleotides are a logical fit: they improve the condition of thin, sun-exposed skin rather than filling it. Treat them as a course, respect their slower healing, and anchor the plan with sun protection for results that look natural on areas that are always in view.
