The Science

Nature's master regenerator.

GHK-Cu (Glycyl-L-histidyl-L-lysine copper) is a naturally occurring copper complex found in human plasma. Discovered in 1973, it remains one of the most studied peptides in regenerative science - activating over 4,000 genes responsible for skin repair, collagen synthesis and hair follicle stimulation.

FAQs

Is this right for my skin type?

Nature meets science in our GHK-Cu collection, designed to harmonize with every skin journey. Since copper peptides are already a natural part of your body’s biology, our formulas work intuitively with your skin rather than against it.

  • Glow-Seekers & Mature Skin: Our absolute favorite for restoring that bouncy, youthful resilience and softening fine lines.
  • Sensitive Souls: Unlike harsh synthetics, GHK-Cu gently nurtures and strengthens your skin barrier, making it a dream for those prone to redness or irritation.
  • Oily & Balanced Profiles: Lightweight and breathable, it clarifies and refines texture without ever feeling heavy or clogging your pores.
  • Dry & Dehydrated Skin: It acts as the perfect "support system" to help your skin better retain moisture and look instantly more revived.

How long does it take to see results for skin?

Most people begin to notice improvements in skin hydration, smoothness, and overall appearance within 2–4 weeks of consistent use. More noticeable improvements in skin texture and appearance typically occur after 6–12 weeks of regular use.

Results can vary depending on skin type, consistency of use, and overall skincare routine.

How long does it take to see results for hair?

Hair growth and thickening is a slow process, so results take longer than skincare. With consistent use, most people may begin to notice improvements in hair thickness, shedding, or scalp condition after 8–12 weeks, with more noticeable results after 3–6 months.

Consistency is very important for hair products.

What is GHK-Cu, the beauty peptide?

GHK-Cu is a naturally occurring copper peptide found in the human body. It is commonly used in skincare and hair products to support skin appearance, hair appearance, and overall scalp health.

In cosmetic products, GHK-Cu is known for helping improve the appearance of:

  • Skin firmness
  • Fine lines and wrinkles
  • Skin texture
  • Hair thickness appearance
  • Scalp condition

It is often called “the beauty peptide” because of its wide range of cosmetic uses for both skin and hair.
