About Pepcare Lab

Science-Led Peptide Skincare. Designed for Sensitive Skin.

At Pepcare Lab, we've chosen to build our collection around copper peptides (GHK-Cu) because of their long history of cosmetic research and their role in supporting healthy-looking skin and the skin's natural barrier.

Our philosophy is simple: combine science-led peptide technology with carefully selected active ingredients to create formulations that support concerns like fine lines, texture, hydration and scalp health—without unnecessarily compromising sensitive skin.

No unnecessary fillers.
No exaggerated claims.
Just purposeful formulations designed to work with your skin, not against it.

Why Copper Peptides?

Peptides have become one of the most talked-about ingredients in health and skincare, but many people don't realise they've been used in cosmetic formulations for decades.

At the heart of every Pepcare Lab product is GHK-Cu (Copper Tripeptide-1), one of the most extensively researched peptide ingredients in cosmetic science.

Naturally occurring in the body, copper peptides are recognised for their role in supporting the skin's natural renewal processes, maintaining the appearance of healthy, resilient skin and supporting the skin barrier.

Rather than chasing trends, we formulate with ingredients chosen for the strength of the research behind them, using purposeful concentrations to deliver meaningful cosmetic benefits.

Because science—not hype—should lead skincare.

Peptide Formulations That Respect Your Skin Barrier

Healthy skin starts with a healthy skin barrier.

Your skin barrier plays an essential role in retaining moisture, supporting skin resilience and protecting against everyday environmental stressors.

Many active skincare routines can leave sensitive skin feeling dry, irritated or compromised.

That's why every Pepcare Lab formulation is designed to balance performance with barrier support—helping improve the appearance of fine lines, uneven texture and dehydration while respecting your skin's natural function.

We believe active skincare should support your skin, not challenge it.

From Face to Scalp

Healthy hair starts with a healthy scalp.

While facial skincare has advanced significantly, scalp care has often been overlooked.

At Pepcare Lab, we apply the same science-led peptide philosophy across our entire collection, extending barrier-focused skincare principles beyond the face to support a healthy scalp environment and healthier-looking hair.

Because your scalp deserves the same thoughtful care as the rest of your skin.

Our Philosophy

Everything we create is guided by a few simple principles.

  • Science-led peptide formulations
  • Designed for sensitive skin
  • Barrier-first skincare
  • Purposeful concentrations of active ingredients
  • Evidence-informed cosmetic formulations
  • Complete ingredient transparency with full INCI lists
  • Australian designed and formulated
  • Cruelty-free

We believe you deserve to know what's in your skincare, why it's there and how it supports your skin.

Meet the Founder

Hi, I'm Marianne, founder of Pepcare Lab.

I created Pepcare Lab because I was searching for active skincare that was effective enough to target fine lines and texture, yet gentle enough for my sensitive skin.

Time and time again, I found myself choosing between products that promised results and products that kept my skin feeling comfortable. Every time I reached for stronger actives, my skin barrier seemed to pay the price.

Why should improving your skin come at the expense of your skin barrier?

That question became Pepcare Lab.

Built around copper peptides and thoughtfully selected active ingredients, every product is designed to support healthy-looking skin and scalp while respecting the skin's natural barrier.

I believe skincare doesn't need to be complicated. It doesn't need ten different steps or the latest viral ingredient. It should be simple, science-led and something you can use consistently with confidence.

My goal is to help people build routines that support healthy skin over the long term—because when your skin barrier is healthy, everything else has a stronger foundation.

Thank you for trusting Pepcare Lab to be part of your skincare journey.

Marianne 💙
