iS Clinical Youth Serum | Copper Tripeptide-1 Firming & Antioxidant Serum

Immediate firming and long-term structural renewal in one serum. Youth Serum uses advanced technologies that visibly firm the skin on application while Copper Tripeptide-1 works beneath the surface to stimulate collagen synthesis and progressively reduce fine lines and wrinkles over time. The Extremozyme technology adds a layer of patented environmental protection that defends against the ongoing damage that makes these improvements necessary in the first place.

Who is Youth Serum best for?

• Fine lines, wrinkles and loss of firmness
• Those wanting both immediate and long-term visible results from a single serum
• Mature or menopausal skin experiencing accelerated collagen loss
• Those on GLP-1 medications experiencing facial volume loss and skin laxity
• Those wanting to complement or extend the results of aesthetic treatments
• Anyone wanting the most comprehensive anti-ageing serum in the iS Clinical range

Key ingredients and why they matter

• Copper Tripeptide-1: Clinically proven to stimulate collagen synthesis in dermal fibroblasts and visibly reduce fine lines and wrinkles over time. The most scientifically substantiated peptide in professional skincare for collagen stimulation
• Extremozymes (proprietary enzyme complex): iS Clinical's patented technology that protects skin proteins and DNA from environmental damage, defending against the UV and pollution exposure that accelerates collagen breakdown
• Immediate firming complex: Advanced technologies that provide a visible tightening and firming effect from the first application, delivering an immediate result while the Copper Tripeptide-1 builds structural improvement over time
• Antioxidant blend: Comprehensive free radical defence that works alongside the Extremozymes for complete environmental protection

What results can you expect?

A visible firming and smoothing effect from the first application. Progressive improvements in fine lines, wrinkles and overall skin quality over 8 to 12 weeks of consistent use. Copper Tripeptide-1 benefits continue to build with long-term consistent use. 30ml.

How we use Youth Serum at Face for Soul

As a pharmacist prescriber specialising in skin health, Youth Serum is the iS Clinical serum I recommend for patients whose primary concern is loss of firmness and fine lines. The combination of immediate visible firming with progressive structural renewal from Copper Tripeptide-1 is genuinely compelling, and the Extremozyme protection adds a clinically distinctive dimension that standard peptide serums lack.

For patients on GLP-1 medications experiencing facial volume loss and accelerated skin laxity, Youth Serum addresses the collagen stimulation and firming dimension of their skin changes. I typically recommend it alongside the iS Clinical Super Serum Advance+ for patients wanting the most complete iS Clinical anti-ageing protocol.

Complete your iS Clinical anti-ageing routine

Apply Youth Serum morning and evening after the iS Clinical Cleansing Complex. Follow with iS Clinical Moisturizing Complex, Youth Intensive Crème or Reparative Moisture Emulsion, and finish with iS Clinical Extreme Protect SPF 40 or Eclipse SPF 50+ in the morning. For the eye area, the iS Clinical Youth Eye Complex applies the same Copper Tripeptide-1 technology to the periorbital skin.

Frequently Asked Questions

Is it suitable if I am on GLP-1 medication?
Yes. The collagen stimulation from Copper Tripeptide-1 and the immediate firming complex directly address the skin laxity and volume loss that many GLP-1 patients experience. It is one of my most consistent serum recommendations for this patient group.

How does it work alongside aesthetic treatments?
Youth Serum pairs well with microneedling, radiofrequency, laser and injectable treatments where collagen stimulation and antioxidant protection between sessions supports and extends clinical results. Always follow your clinician's post-treatment advice on when to restart actives.

Is iS Clinical cruelty-free?
Yes. iS Clinical does not test on animals.

Is it vegan?
iS Clinical formulates without animal-derived ingredients in the majority of its products.

How to Use
