Alastin - Restorative Skin Complex 2.0

ALASTIN Restorative Skin Complex 2.0 — TriHex+ Peptide Serum, 29ml

ALASTIN Restorative Skin Complex 2.0 is an advanced, peptide-powered rejuvenating serum designed to improve the appearance of collagen- and elastin-depleted skin. This daily multi-tasking treatment targets skin texture, tone, visible volume, hydration, elasticity, fine lines and wrinkles within one comprehensive formula.

The updated 29ml formulation introduces TriHex+™ technology, enhanced with proprietary Octapeptide-45, alongside magnolol, niacinamide, ceramides and antioxidants. Together, these technologies support the skin’s natural production of new, healthy collagen, elastin and high-molecular-weight hyaluronic acid while promoting visible, long-term volumisation in thinning skin.

This listing is for the new-generation Restorative Skin Complex with TriHex+ and its updated packaging. Other ALASTIN products available in the UK retain their individual product-specific TriHex formulations.

A Powerful Peptide Serum for Multiple Signs of Ageing

Visible skin ageing rarely presents as a single concern. Loss of collagen and elastin can appear alongside reduced firmness, thinner-looking skin, fine lines, dehydration, dullness and uneven texture.

Restorative Skin Complex 2.0 is formulated as a high-performance daily treatment for these interconnected changes. Its benefits include:

• Improving the appearance of fine lines and wrinkles.
• Supporting visibly firmer and more elastic-looking skin.
• Promoting long-term visible volumisation in thinning skin.
• Helping restore facial plumpness and fullness.
• Improving skin texture and surface smoothness.
• Supporting long-lasting hydration.
• Targeting dullness and uneven-looking tone.
• Helping protect the skin against environmental stressors.
• Supporting the skin’s natural regenerative abilities at every age.

What Is TriHex+ Technology?

TriHex+ is ALASTIN’s next-generation peptide technology, enhanced with proprietary Octapeptide-45. It is designed to support the skin’s natural production of new, healthy collagen and elastin while adding support for high-molecular-weight hyaluronic acid.

These three components are central to the appearance of youthful skin:

• Collagen contributes to structural support, firmness and surface smoothness.
• Elastin allows skin to stretch and return towards its original position, contributing to visible resilience.
• Hyaluronic acid binds water and contributes to hydration, suppleness and visible plumpness.

By targeting all three, Restorative Skin Complex 2.0 provides a more comprehensive approach to visible skin regeneration than a conventional moisturising or single-peptide serum.

How TriHex+ Differs from Original TriHex

Original TriHex Technology uses a proprietary blend of peptides and supporting ingredients to help clear damaged proteins from the skin’s extracellular matrix and support the production of new collagen and elastin.

TriHex+ advances this platform by incorporating Octapeptide-45, extending its focus to include the skin’s natural production of high-molecular-weight hyaluronic acid. This gives the updated Restorative Skin Complex a combined focus on:

• Collagen renewal.
• Elastin renewal.
• Long-lasting hydration.
• Visible skin plumpness.
• Structural and surface skin quality.

Read the complete ALASTIN TriHex and TriHex+ technology guide for a detailed explanation of the two platforms.

Octapeptide-45: Collagen, Elastin and Hyaluronic Acid Support

Octapeptide-45 is ALASTIN’s proprietary peptide incorporated into the new TriHex+ platform. Within Restorative Skin Complex 2.0, it helps support the skin’s natural production of:

• New, healthy collagen.
• New, healthy elastin.
• High-molecular-weight hyaluronic acid.

This makes Octapeptide-45 a central component of the serum’s approach to firmness, elasticity, hydration and visible volume.

The same proprietary peptide is also used within ALASTIN HA IMMERSE Serum, where its role is concentrated around hyaluronic acid support and advanced hydration. Restorative Skin Complex places it within a broader multi-peptide rejuvenating formula.

Magnolol and Visible Facial Volumisation

Magnolol is one of the most distinctive additions to Restorative Skin Complex 2.0. ALASTIN includes magnolol to support the body’s natural production of healthy facial adipose tissue and improve the appearance of skin plumpness and volume.

Facial fat contributes to youthful contours and surface support. As the face changes with age or substantial weight loss, reduced fullness can make lines, laxity and thinning skin more noticeable.

Magnolol complements the collagen-, elastin- and HA-supporting activity of TriHex+ to promote visible, long-term volumisation. This gives Restorative Skin Complex 2.0 a valuable position for skin that appears thinner, less supported or less full than previously.

Key Peptides in Restorative Skin Complex 2.0

The serum contains a sophisticated combination of peptides rather than relying on a single peptide pathway:

• Palmitoyl Hexapeptide-12: a key component of ALASTIN’s original TriHex platform associated with elastin support and visible firmness.
• Palmitoyl Tripeptide-1: supports the formula’s collagen-focused approach to skin structure and smoothness.
• Palmitoyl Tripeptide-5: contributes further collagen-supporting peptide activity.
• Palmitoyl Dipeptide-5 derivatives: complementary peptides used within the broader regenerative complex.
• Acetyl Hexapeptide-38: included within the volumising and skin-conditioning formulation.
• Octapeptide-45: enhances TriHex+ support for collagen, elastin and high-molecular-weight hyaluronic acid.

Niacinamide, Ceramides and Antioxidant Support

Niacinamide

Niacinamide supports the appearance of more even-toned, resilient and refined-looking skin. Its position near the top of the ingredient list makes it an important part of the finished formulation rather than a minor supporting addition.

Ceramides AP and NP

Ceramides are naturally occurring skin lipids that contribute to barrier integrity and moisture retention. Their inclusion complements the serum’s focus on hydration, resilience and skin quality.

Ergothioneine and Antioxidants

Ergothioneine, tocopherol and botanical-derived antioxidants help defend the skin against environmental oxidative stress that can contribute to visible ageing and dullness.

Squalane and Phytosterols

These skin-conditioning lipids support softness, comfort and suppleness, helping the advanced peptide complex sit within an elegant daily treatment formula.

Clinical Results

In an ALASTIN clinical study, Restorative Skin Complex with TriHex+ produced strong participant-reported results in as early as 12 weeks:

• 98% agreed that it improved skin hydration.
• 89% reported improvements in overall skin texture.
• 93% reported overall satisfaction with the product.

Clinical photography also documented visible improvements in surface roughness, redness, fine lines and wrinkles, skin dullness and loss of volume.

Who Is Restorative Skin Complex 2.0 For?

This multi-tasking serum is particularly well suited to adults experiencing several signs of visible ageing together, including:

• Fine lines and wrinkles.
• Loss of visible firmness or elasticity.
• Thinning or less supported-looking skin.
• Reduced facial plumpness and volume.
• Uneven or rough skin texture.
• Dullness and uneven-looking tone.
• Dehydration and reduced suppleness.
• Visible effects of environmental stress.
• Age-related or weight-loss-associated changes in skin quality.

Its multi-functional formulation makes it especially valuable for people who want one premium serum to address several aspects of visible skin ageing rather than building a routine from numerous overlapping treatment products.

Restorative Skin Complex and Collagen-Depleted Skin

Collagen depletion can contribute to fine lines, reduced firmness and changes in surface texture. The peptide system in Restorative Skin Complex is designed to support the skin’s natural production of new, healthy collagen while helping optimise the extracellular environment in which collagen and elastin are formed.

This regenerative approach is central to the ALASTIN philosophy: support the removal of damaged or fragmented proteins and promote an environment favourable to renewed collagen and elastin production.

Restorative Skin Complex and Elastin-Depleted Skin

Elastin is essential to the skin’s ability to stretch and recoil. Unlike collagen, mature elastin has a particularly slow natural turnover rate, making elastin-focused skincare technology relatively specialised.

TriHex technology was developed with elastin support as a defining objective. The updated TriHex+ formulation retains that focus while adding enhanced support for collagen and high-molecular-weight hyaluronic acid.

Restorative Skin Complex for Thinning and Less Plump Skin

Restorative Skin Complex 2.0 combines three complementary approaches to thinning or less full-looking skin:

1. Structural support through collagen- and elastin-focused peptide technology.
2. Hydration and visible plumping through Octapeptide-45 and high-molecular-weight HA support.
3. Visible volumisation through magnolol and its support for healthy facial adipose tissue.

This multi-pathway approach is one of the product’s strongest differentiators and makes it particularly relevant where ageing or weight change has affected skin firmness, resilience and visible facial fullness.

How to Use ALASTIN Restorative Skin Complex

1. Cleanse the face and allow the skin to dry.
2. Apply one to two pumps of Restorative Skin Complex.
3. Distribute evenly across the face morning and evening.
4. Follow with additional targeted skincare and moisturiser as required.
5. Complete the morning routine with broad-spectrum sunscreen.

Consistent twice-daily application provides the best opportunity for the formulation’s cumulative peptide, hydration and volumising benefits to develop.
