What Are Peptides?

Understanding their role in Skin biology — and why we use GHK Peptides

What Are Peptides?

Peptides are short chains of amino acids that act as biological messengers.

Depending on their function, peptides can be classified into four main types: Signaling, carrier, enzyme-inhibiting, and neurotransmitter-inhibiting peptides. Among these, peptides like GHK are known for their signaling and carrier functions, stimulating skin regeneration by activating specific cellular responses.

ALTUM® Uses GHK

— A Regenerative Peptide Found in the Human Body

What is GHK?

GHK (Glycyl-L-histidyl-L-lysine) is a naturally occurring tripeptide found in human plasma. It binds copper ions (Cu²⁺) and plays a key role in skin physiology and tissue regeneration.

What It Does in the Body:

• Stimulates collagen, elastin, and extracellular matrix synthesis

• Enhances epidermal stem cell activity

• Modulates over 4,000 genes related to wound healing and inflammation

• Supports tissue repair, barrier restoration, and skin firmness

Why It Matters for Skin?

GHK levels are highest in youth but decline significantly with age, reducing the skin’s natural regenerative capacity.

Why GHK Is Trusted?

— Safe, Recognized, and Clinically Proven

• Body Recognition & Safety

  • Naturally produced in the human body

  • Biocompatible — does not trigger immune or allergic responses

  • Safe for sensitive and compromised skin

• Seamless Biological Integration

  • Works harmoniously with skin’s natural processes

  • Supports regeneration without disrupting normal function

• Clinically Proven Efficacy

  • Supported by numerous scientific studies and clinical trials

  • Demonstrated regenerative, healing, and anti-inflammatory effects
