The Science

THE SCIENCE

What Are Peptides

Peptides are short chains of amino acids that act as messengers in the skin. They signal your skin cells to perform specific functions, such as producing collagen, repairing damage, and maintaining the skin barrier. Unlike harsh active ingredients that force results, peptides work with your skin's natural biology to deliver real, lasting change.

GHK-Cu — Copper Peptide Complex

GHK-Cu is one of the most extensively researched bioactive compounds in modern dermatology, with over 50 years of peer-reviewed clinical studies behind it. Naturally present in human plasma, GHK-Cu levels decline significantly with age, which contributes to the visible signs of skin aging.

Clinically, GHK-Cu has been shown to:

  • Stimulate collagen and elastin synthesis
  • Activate the skin's natural repair enzymes
  • Strengthen the skin barrier
  • Reduce inflammation and oxidative stress
  • Promote cellular renewal and regeneration

SNAP-8 — Acetyl Octapeptide-3

SNAP-8 is one of the most advanced anti-wrinkle peptides available in cosmetic science. It works by moderating the release of neurotransmitters that cause facial muscle contractions — the same mechanism responsible for the formation of expression lines and wrinkles. Clinical studies show SNAP-8 can visibly reduce the depth of expression wrinkles by up to 63%.

Hyaluronic Acid

Hyaluronic acid is one of the most clinically validated hydration ingredients in skincare. Naturally found in the skin, hyaluronic acid holds up to 1000 times its weight in water. Our multi-weight complex delivers hydration at multiple skin depths — instantly plumping the surface while supporting long-term moisture retention deep within the skin.

Panthenol — Vitamin B5

Panthenol is a proven skin conditioning agent that penetrates deeply into the skin to provide long-lasting hydration, soothe irritation, and strengthen the skin barrier. It works synergistically with peptides to support the skin's natural repair process.

Why Radova

Most skincare brands start with a trend and work backward to find ingredients that fit. We do the opposite. Every Radova formula starts with peer-reviewed research and is built around ingredients with documented clinical efficacy. No fillers. No trends. Just science that works.
