Alastin - Restorative Neck Complex

ALASTIN Restorative Neck Complex 50ml — TriHex Neck and Décolleté Treatment

ALASTIN Restorative Neck Complex is an advanced neck treatment, which ALASTIN reports is clinically shown to improve the appearance of crepey skin, wrinkles, uneven texture and discolouration across the neck and décolleté.

Powered by patented TriHex Technology®, this advanced 50ml formulation helps clear damaged collagen and elastin fragments while supporting the skin’s natural production of new, healthy collagen and elastin.

Phytoene, phytofluene, niacinamide, flax seed extract, Acetyl Tetrapeptide-2, ceramides and intensive hydration ingredients provide additional support for visible firmness, elasticity, pigmentation, redness and moisture.

This is the established UK Restorative Neck Complex with original TriHex Technology and original product packaging. It is distinct from the new TriHex+ formulation used specifically in Restorative Skin Complex 2.0.

A Dedicated Treatment for the Neck and Décolleté

The skin between the chin and upper chest has characteristics that make it particularly vulnerable to visible ageing. It is thinner than much of the facial skin, has fewer sebaceous glands and is regularly exposed to ultraviolet radiation, movement and environmental stress.

These factors can contribute to:

• Crepey or finely folded skin texture.
• Horizontal neck lines and wrinkles.
• Reduced visible firmness and elasticity.
• Redness and uneven pigmentation.
• Photo-ageing across the neck and upper chest.
• Dryness and reduced suppleness.
• A visible contrast between the face, neck and décolleté.

Restorative Neck Complex combines peptide technology, pigment-focused antioxidants and intensive moisture support within one specialised treatment for this often-overlooked area.

What Does ALASTIN Restorative Neck Complex Do?

• Improves crepey skin: helps the neck appear smoother, firmer and more refined.
• Reduces visible lines and wrinkles: targets fine creasing across the neck and décolleté.
• Supports collagen and elastin renewal: patented TriHex Technology helps clear damaged protein fragments and supports new, healthy collagen and elastin.
• Improves visible firmness: supports skin that appears tighter, stronger and more resilient.
• Targets pigmentation: phytoene, phytofluene and niacinamide address visible discolouration and photo-aged skin.
• Minimises redness: antioxidant technology helps promote a calmer and more even-toned appearance.
• Increases hydration: flax seed extract, hyaluronic-acid-supporting ingredients, ceramides and emollients nourish and soften the skin.
• Supports the décolleté: treats visible ageing across both the neck and exposed upper chest.

TriHex Technology: Remove, Rebuild and Replenish

TriHex Technology is ALASTIN’s patented blend of active peptides and botanicals developed to support collagen and elastin renewal.

Its approach is built around three connected stages:

1. Remove: help clear aged and damaged collagen and elastin fragments from the extracellular matrix.
2. Rebuild: establish a more favourable environment for the production of new structural proteins.
3. Replenish: support the continued natural production of healthy collagen and elastin through consistent use.

Within Restorative Neck Complex, TriHex is applied to an area where visible laxity, crepiness, wrinkles and thinning can become particularly noticeable.

Why Collagen and Elastin Matter for the Neck

Collagen

Collagen provides structural support and tensile strength. Ageing and ultraviolet exposure can reduce both the quantity and organisation of collagen, contributing to wrinkles, uneven texture and reduced firmness.

Elastin

Elastin allows the skin to stretch and recoil. The neck is continually moving through turning, looking down and changes in posture, making visible elasticity especially important in this area.

TriHex supports both damaged-protein clearance and the skin’s natural production of new collagen and elastin, helping improve the visible quality, resilience and smoothness of neck skin.

Key Technologies and Ingredients

TriHex Technology

A patented combination of peptides and active ingredients that helps clear damaged elastin and collagen while supporting the skin’s ability to produce new, healthy structural proteins.

Palmitoyl Hexapeptide-12

A lipid-linked peptide central to the TriHex platform. It supports the extracellular environment associated with elastin renewal, visible firmness and skin resilience.

Palmitoyl Tripeptide-1

A collagen-supporting peptide incorporated into the TriHex system to help improve the appearance of lines, texture and structural skin quality.

Acetyl Tetrapeptide-2

A specialised peptide selected to support elastin production and improve the appearance of skin tightness and firmness.

Phytoene and Phytofluene

Phytoene and phytofluene are potent colourless carotenoid antioxidants derived from Dunaliella salina. They help address visible redness, pigmentation and photo-aged skin while supporting antioxidant protection.

Niacinamide

Niacinamide supports a brighter, more even-toned appearance while contributing to barrier resilience and antioxidant defence. It strengthens the formulation’s approach to redness and visible discolouration.

Flax Seed Extract

Flax seed extract supplies omega-3 fatty acids and antioxidants while supporting natural hyaluronic acid levels. It helps restore and retain hydration while nourishing and softening the skin.

Ceramide NP

Ceramide NP reinforces the skin’s moisture barrier, supporting improved water retention, comfort and resilience.

Silver Mushroom Extract

Tremella fuciformis provides additional moisture-binding and conditioning benefits for dry or crepey-looking skin.

Squalane and Shea Butter Extract

These emollient ingredients help replenish softness, smoothness and comfort across the naturally drier neck and décolleté.

Restorative Neck Complex for Crepey Skin

Crepey skin has a finely wrinkled, paper-like appearance associated with changes in collagen, elastin, hydration and skin thickness. It is particularly common across the neck and upper chest because these areas combine thin skin with frequent movement and cumulative sun exposure.

Restorative Neck Complex addresses crepiness through several pathways:

• TriHex support for collagen and elastin renewal.
• Acetyl Tetrapeptide-2 for visible firmness.
• Flax seed extract and silver mushroom for hydration.
• Ceramide NP for moisture-barrier support.
• Squalane and shea-derived emollients for softness and suppleness.

Consistent morning and evening use helps the skin appear smoother, tighter, more hydrated and more resilient.

Restorative Neck Complex for Pigmentation and Sun Damage

The décolleté is one of the most sun-exposed areas of the body, but it is often excluded from daily skincare and sunscreen application. This can lead to visible mottling, redness, uneven pigmentation and accelerated photo-ageing.

Restorative Neck Complex combines phytoene, phytofluene, niacinamide and additional antioxidants to address:

• Uneven-looking pigmentation.
• Visible redness.
• Dull or photo-aged skin.
• Uneven tone between the face, neck and chest.

Daily broad-spectrum sunscreen over the neck and décolleté helps protect the visible improvements supported by the treatment.

Clinical Results

ALASTIN has clinically evaluated Restorative Neck Complex when used twice daily across the neck and décolleté.

Clinical photography recorded visible improvements in:

• Crepey skin texture.
• Neck lines and wrinkles.
• Wrinkles across the upper chest.
• Skin smoothness.
• Visible tone and pigmentation.
• Overall neck and décolleté appearance.

Visible improvements in crepey skin and wrinkles were documented after four weeks of twice-daily use. The photographed subjects used Restorative Neck Complex without an accompanying professional procedure, allowing the changes to be assessed within a dedicated homecare regimen.

Why Use a Separate Neck Treatment?

A facial moisturiser can provide general hydration, but Restorative Neck Complex is built specifically around the biological and visible characteristics of the neck and chest.

Its dedicated formulation offers:

• TriHex peptide technology for collagen and elastin support.
• Acetyl Tetrapeptide-2 for visible tightening.
• Phytoene and phytofluene for photo-ageing and pigmentation.
• Niacinamide for visible tone and barrier support.
• A richer moisture system appropriate for an area with fewer oil glands.
• Clinical evaluation specifically involving the neck and décolleté.

This allows the area to receive targeted care rather than relying entirely on products developed principally for the face.

Who Is Restorative Neck Complex For?

This advanced neck treatment is particularly relevant for adults concerned about:

• Crepey or finely wrinkled neck skin.
• Horizontal neck lines.
• Wrinkles across the décolleté.
• Reduced firmness and elasticity.
• Uneven pigmentation or redness.
• Sun damage across the neck and upper chest.
• Dryness and reduced suppleness.
• Visible ageing following weight change.
• A mismatch between facial and neck skincare results.

ALASTIN formulates Restorative Neck Complex for all skin types, including dry, oily and combination complexions.
