Décolletage & Neck Rejuvenation

Why the neck and décolletage age differently

Facial skin is supported by dense collagen, muscular attachments and a relatively thick epidermis. The skin over the neck and upper chest is not. Its stratum corneum — the outermost barrier — is measurably thinner, and the underlying dermis contains fewer fibroblasts producing new collagen. Add cumulative sun exposure (the décolletage receives more incidental UV than almost any other body site), repeated mechanical folding from side-sleeping, and the downward pull of gravity on relatively unsupported tissue, and the result is a predictable pattern of ageing:

• Crepey, tissue-paper texture from dermal thinning and dehydration.
• Horizontal 'necklace' lines — habitual creases that become permanent.
• Vertical cleavage wrinkles from side-sleeping and reduced elasticity.
• Sun-induced pigmentation: freckling, mottling, poikiloderma of Civatte.
• Loss of firmness along the jawline-to-neck junction.

Because several causes coexist, one modality is rarely enough. We categorise treatments by depth of action — from superficial to deep — and build a protocol that addresses each layer in turn.

Layer 1 · Superficial

Chemical peels for pigmentation, texture and tone

Peels work on the epidermis and upper dermis. On the neck and chest they are used to lift sun damage, brighten mottled pigmentation and encourage a smoother surface — the essential first step before any biostimulator, because a healthier epidermis reflects light more evenly and lets deeper treatments show their true result.

• Glycolic acid peels (20–40%) — light, well tolerated, ideal as a course of 4–6 sessions for early sun damage and dullness. See glycolic peel.
• Lactic acid peels — the gentlest option, safe on very thin décolletage skin and on darker Fitzpatrick types. Lactic acid peel.
• Salicylic acid peels — best where the chest is prone to blocked follicles or congestion alongside sun damage. Salicylic peel.
• TCA peels (medium depth) — used cautiously on the neck at lower concentrations for entrenched pigmentation and fine crepiness. TCA peel.

Peels are the least expensive step and set the stage. They will not restore lost dermal thickness or lift crepey skin on their own — for that, we move deeper.

Layer 2 · Intradermal

Skin boosters for hydration and quality

Skin boosters are micro-injections of soft, non-crosslinked hyaluronic acid (often combined with amino acids or vitamins) placed just under the surface. They do not add volume in the way a dermal filler does — they rehydrate the dermis, improve elasticity and restore a healthy 'glow' to the neck and cleavage.

• Profhilo — the most studied HA bio-remodeller. Ultra-pure hyaluronic acid that spreads through the tissue and stimulates all four types of collagen and elastin. Delivered as 5 BAP points either side of the neck, two sessions one month apart. Ideal first-line for early crepiness.
• Sunekos — HA plus a patented amino-acid blend that rebuilds the extracellular matrix. Particularly useful on thin décolletage skin.
• Jalupro — amino-acid rich booster that supports fibroblast activity; a good option for lifestyle-related dullness.

Skin boosters are the pivot point of any décolletage protocol: they treat the cause of thinning rather than masking its symptoms.

Layer 3 · Regenerative

Polynucleotides for wrinkles and dermal thickness

Polynucleotides are highly purified DNA fragments (typically from salmon or trout milt) that act directly on fibroblasts. Rather than filling a line, they instruct the skin to rebuild its own scaffold — collagen, elastin and extracellular matrix. On the neck and cleavage this produces a genuine increase in dermal thickness, visibly softer horizontal necklace lines and reduced crepiness over a course of 3 sessions spaced 2–3 weeks apart.

We consider polynucleotides the definitive answer for patients whose main concern is quality rather than volume: thin, tissue-paper skin that looks fragile even when hydrated. See polynucleotide treatment for the full clinical protocol.

Layer 4 · Deep biostimulation

Radiesse and calcium hydroxylapatite biostimulators

For patients with established laxity, loss of firmness and a papery, sagging quality across the whole décolletage, hyper-diluted Radiesse (calcium hydroxylapatite) is the most effective option we offer short of surgery. The microspheres are diluted with saline and lidocaine and delivered through a blunt cannula in a fanning pattern across the chest and lower neck.

The calcium hydroxylapatite microspheres act as a scaffold for the patient's own fibroblasts to lay down new type I and type III collagen and elastin. Results build gradually over 3–6 months and last 12–18 months. Because it is diluted, Radiesse used here is a collagen stimulator, not a volumiser — the result is thicker, firmer, more resilient skin, not a filled-out appearance.

Radiesse is particularly well suited to the chest because the area tolerates biostimulation beautifully and shows visible textural improvement that no HA product can match at the same depth.

Layer 5 · Targeted correction

Dermal fillers for cleavage wrinkles and necklace lines

Where individual lines remain after the layers above — vertical cleavage creases from side-sleeping, or a single deep necklace band — soft, low-G′ hyaluronic acid fillers are placed intradermally with a fine needle or micro-cannula. The goal is to smooth the line without creating a visible ridge; this is technically demanding and belongs in doctor-led hands.

How we combine the layers

A typical décolletage rejuvenation programme runs over 8–12 weeks and combines two or three of the layers above. Examples of protocols we frequently prescribe:

• Early sun damage, tone concerns: course of 4 glycolic peels + prescription antioxidant homecare.
• Crepey texture, no lines yet: 2 sessions Profhilo, spaced 4 weeks, followed by one polynucleotide session at week 12.
• Thin skin plus visible cleavage wrinkles: 3 polynucleotide sessions, then soft HA filler placed intradermally in the residual lines.
• Established laxity across the whole chest: hyper-diluted Radiesse, one to two sessions, layered over an initial peel to optimise skin surface.

What we do not recommend

We do not use thick, highly cross-linked structural fillers on the neck or chest — the risks of visible lumps and vascular events outweigh any benefit. We also avoid aggressive ablative resurfacing on very thin décolletage skin. If crepiness has progressed to true surgical laxity, we will say so and discuss appropriate onward referral rather than over-treating.
