GHKCU, is a naturally occurring copper peptide that shows up when your body is healing. It helps repair tissue, build collagen, and improve blood flow, which is why it’s become the fan favorite for skin, hair, and anything labeled anti-aging. You don’t need to inject this one. It’s built into face serums, healing creams, and scalp treatments.
On skin, it smooths fine lines and wrinkles, fades redness, and helps tissue recover faster after micro needling or lasers. On the scalp, it’s used to strengthen follicles and improve circulation, which may help slow thinning and support hair retention. And this one isn’t just hype. Studies show measurable improvements in collagen, skin thickness, and elasticity with regular use.
Research on hair is less extensive, but early results suggest it may help reduce shedding and support new growth over time. It’s easy to get in both over-the-counter and prescription forms and gentler than most active skincare ingredients. Unlike retinol, it rarely causes irritation, dryness, or flaking, which makes it easier to stick with long term. If there’s one catch, it’s patience. GHKCU takes time to work, but if you’re willing to keep at it, it could be a relatively painless way to shed a few years.
