Alastin Restorative Skin Complex with TriHex®

The skin's ability to produce collagen and elastin does not simply slow down with age. It becomes blocked. Damaged, degraded proteins accumulate in the dermis over decades and physically prevent the fibroblasts responsible for collagen synthesis from doing their job effectively. Most anti-ageing serums try to stimulate production without addressing this blockage. Alastin Restorative Skin Complex addresses both problems simultaneously.

Developed by a physician-founded team and backed by multiple independent clinical studies, Restorative Skin Complex uses Alastin's proprietary TriHex Technology to clear degraded elastin and collagen fragments from the dermis while simultaneously stimulating fibroblasts to produce new, healthy structural proteins. The result is not a temporary surface improvement but a genuine structural renewal of the dermis that produces progressively better skin with continued use. It is the most comprehensively studied serum in the Alastin range and one of the most clinically substantiated anti-ageing serums available without a prescription.

Multiple award-winner. Non-comedogenic. Suitable for all skin types and all ages.

Who Is It For?

• Ageing skin with loss of firmness, elasticity and structural integrity
• Menopausal skin experiencing accelerated collagen and elastin decline
• Patients on GLP-1 medications such as Ozempic, Wegovy, Mounjaro or Zepbound experiencing skin laxity and quality changes
• Those wanting to prepare skin for cosmetic procedures for better outcomes
• Those recovering from laser, microneedling, radiofrequency or peel treatments
• Those wanting the most clinically substantiated anti-ageing serum in the Alastin range
• Anyone whose skin looks dull, tired or structurally depleted despite regular skincare

How Does It Work?

TriHex Technology works in two phases. In the first phase, specialised peptides signal fibroblasts to clear the accumulated fragments of degraded collagen and elastin that obstruct new protein synthesis. This clearance phase is what makes Alastin fundamentally different from peptide serums that simply stimulate production without removing the barrier to it. In the second phase, a comprehensive peptide complex stimulates fibroblasts to produce new collagen, elastin and hyaluronic acid in the cleared dermal space. The skin rebuilds from the inside out rather than being temporarily plumped at the surface.

Key Ingredients

• TriHex Technology (proprietary peptide complex): A patented combination of peptides that simultaneously clears degraded structural proteins from the dermis and stimulates fibroblasts to produce new collagen, elastin and hyaluronic acid. The mechanism is unique to Alastin and supported by multiple independent peer-reviewed studies.
• Palmitoyl Tripeptide-1 and Palmitoyl Tetrapeptide-7: Signal molecules that communicate with fibroblasts to support collagen synthesis and reduce the inflammatory signals that inhibit structural protein production.
• Vitamin C (stable form): Provides antioxidant protection and supports collagen synthesis alongside the peptide complex.
• Niacinamide: Reduces inflammation, improves barrier function, brightens uneven tone and supports overall skin quality throughout the renewal process.
• Hyaluronic Acid: Provides immediate and lasting hydration, maintaining skin comfort throughout the structural renewal process.

Benefits

• Firms and lifts skin by rebuilding the structural protein matrix from within
• Improves skin elasticity and resilience with continued use
• Brightens and evens skin tone alongside structural renewal
• Reduces the appearance of fine lines and wrinkles progressively
• Prepares the dermis for better procedural outcomes
• Accelerates and enhances post-procedure recovery
• Suitable for all skin types including sensitive skin
• Non-comedogenic

What Results Can You Expect?

Immediately: skin feels smoother and more hydrated from the first application. At 2 weeks: improved skin texture and radiance with consistent twice-daily use. At 6 weeks: visible improvements in firmness, elasticity and overall skin quality as the TriHex clearance and rebuilding process gains momentum. At 3 months: significant structural improvement with continued use. Clinical studies confirm measurable improvements in collagen density and skin firmness over this period.

How We Use It at Face for Soul

As a pharmacist prescriber specialising in skin health, Restorative Skin Complex is the Alastin product I recommend most consistently across the broadest range of patients. It is my go-to serum for menopausal patients with significant collagen and elastin decline, for patients on GLP-1 medications experiencing accelerated skin ageing, and for anyone preparing for or recovering from an in-clinic cosmetic procedure. The clinical evidence behind TriHex Technology is genuinely robust and I recommend this serum with considerable confidence.

In clinical practice, I pair it with the Alastin Regenerating Skin Nectar for patients undergoing procedures, as the combination of clearance and rebuilding that TriHex provides before and after treatment consistently improves procedural outcomes compared to standard post-procedure care alone. For patients not undergoing procedures, I recommend it alongside the Alastin C-RADICAL Defense Antioxidant Serum in the morning for comprehensive daily antioxidant protection and structural renewal.

How to Use

Apply 2 to 3 pumps to clean, dry skin morning and evening before moisturiser. Gently smooth over the face and neck. Allow to absorb before applying the next step. Follow with a moisturiser appropriate for your skin type and SPF in the morning. Pair with: Alastin C-RADICAL Defense in the morning, Alastin Ultra Nourishing Moisturizer, and Alastin Regenerating Skin Nectar if undergoing procedures. No specific products to avoid, but allow the serum to absorb fully before layering other actives.

Frequently Asked Questions

Is it worth the money?
Restorative Skin Complex is the most clinically studied serum in the Alastin range and one of the most independently validated anti-ageing serums at any price point. The TriHex mechanism is patented and unique. If you are looking for a serum with published peer-reviewed evidence of structural skin improvement, this is one of very few that genuinely qualifies. As a prescriber who has used it in clinical practice, I recommend it with confidence.

Can I use it with tretinoin?
Yes. Apply tretinoin in the evening first and allow it to absorb, then apply Restorative Skin Complex as the next step. The two work well together as tretinoin accelerates cellular turnover and TriHex Technology simultaneously addresses the structural clearance and rebuilding process in the dermis.

Is it pregnancy safe?
Restorative Skin Complex does not contain retinoids or hydroquinone. We always recommend consulting your midwife or obstetrician before starting any new skincare product during pregnancy.

Is it suitable for rosacea-prone skin?
Yes. The formula is free from fragrance, alcohol and common rosacea triggers. The peptide actives are anti-inflammatory in their mechanism and the formula is suitable for sensitive and reactive skin types.

Can I use it after microneedling?
Yes, and this is one of the most valuable use cases. Restorative Skin Complex used in the days and weeks following microneedling directly supports the dermal rebuilding process that microneedling initiates. Wait until your clinician confirms it is appropriate to reintroduce actives, typically 24 to 48 hours, then apply consistently throughout your recovery and results maintenance period.

Can I combine it with Vitamin C?
Yes. Apply Vitamin C serum first in the morning, allow to absorb, then apply Restorative Skin Complex. The Alastin C-RADICAL Defense Antioxidant Serum is specifically formulated to pair with the Restorative Skin Complex as a morning antioxidant step.

Does it clog pores?
No. Restorative Skin Complex is non-comedogenic and has been tested across all skin types including oily and acne-prone skin.

How long will one bottle last?
A 30ml bottle used twice daily on the face and neck typically lasts 6 to 8 weeks.

Is it suitable on GLP-1 medication?
Yes. Restorative Skin Complex is one of the most targeted topical options for the accelerated collagen and elastin decline that many patients experience during significant weight loss on GLP-1 medications. The TriHex mechanism addresses structural skin ageing at a depth that most serums cannot reach.

How does it compare to a standard peptide serum?
Most peptide serums simply stimulate collagen production. Restorative Skin Complex first clears the accumulated debris of degraded collagen and elastin that blocks effective new protein synthesis, then stimulates production in the cleared space. This two-phase approach is what the peer-reviewed clinical evidence supports and what makes it fundamentally different from standard peptide formulas.

Is it vegan?
Yes. Alastin Restorative Skin Complex is formulated without animal-derived ingredients.

Is it cruelty-free?
Yes. Alastin does not test on animals.

Clinical Insight

As a pharmacist prescriber specialising in skin health, I recommend Restorative Skin Complex when a patient's skin has lost structural integrity in a way that surface hydration and standard peptide serums cannot address. The two-phase TriHex mechanism is the most compelling evidence-based approach to topical collagen and elastin restoration I have encountered. For patients on GLP-1 medications, for menopausal patients, and for patients undergoing or recovering from cosmetic procedures, this is my first serum recommendation in the Alastin range.

Research and Evidence

Restorative Skin Complex is supported by multiple independent peer-reviewed clinical studies. TriHex Technology has been the subject of published research demonstrating its ability to clear degraded elastin and collagen from the dermis and stimulate new structural protein synthesis. Clinical studies have confirmed measurable improvements in skin firmness, collagen density and overall skin quality with consistent use. Independent investigator studies have validated its efficacy before and after cosmetic procedures including laser resurfacing and radiofrequency treatments. The research is independent, published and not solely funded by Alastin.

How Does It Compare?

Restorative Skin Complex vs C-RADICAL Defense: C-RADICAL Defense is an antioxidant serum optimised for morning use and environmental protection. Restorative Skin Complex is a structural renewal serum best used morning and evening. They are designed to be used together rather than as alternatives, with C-RADICAL in the morning and both in the evening.

Restorative Skin Complex vs Regenerating Skin Nectar: The Nectar is formulated specifically for pre and post-procedure use and is more intensive than the Restorative Skin Complex. For daily home use without a procedure, Restorative Skin Complex is the appropriate choice. For patients undergoing treatments, using the Nectar around the procedure and the Complex for ongoing daily maintenance is the recommended protocol.

Restorative Skin Complex vs skinbetter science Alto Defense Serum: Alto Defense provides 19-antioxidant protection and is a morning antioxidant serum. Restorative Skin Complex provides structural collagen and elastin renewal. They address different concerns and work well as a combined protocol for comprehensive daily skin health.

Complete Your Routine

Morning: gentle cleanser, Alastin C-RADICAL Defense Antioxidant Serum, Alastin Restorative Skin Complex, Alastin Ultra Nourishing Moisturizer, SPF 30 or higher. Evening: gentle cleanser, Alastin Restorative Skin Complex, Alastin Ultra Nourishing Moisturizer. For procedure support, add Alastin Regenerating Skin Nectar before and after your treatment as directed. For the eye area, add Alastin Restorative Eye Treatment morning and evening.
