The Copper Peptide Everyone in Skincare Is Talking About — Now in a Balm That Actually Works With Your Skin.
GHK-CU signals your skin to renew collagen. We built our richest tallow balm around it, then stacked it with seven more powerhouse ingredients so it firms, repairs, and hydrates from the very first jar.
Your Skin Is Working Harder Than It Used To
Collagen production slows every year after your mid-20s. The result shows up as fine lines, dullness, and skin that just doesn't bounce back the way it used to — no matter how much you moisturize.
We Built This Around One Ingredient That Actually Delivers
Birch & Oak formulates small batches with active ingredients that have research behind them — not just a nice smell. GHK-CU is a naturally occurring copper peptide shown to signal collagen renewal, and it's the reason we built an entire balm around it instead of burying it in a long ingredient list.
We didn't stop there. We paired it with grass-fed tallow, manuka honey, arnica, ground pearl, and more, so every application is doing real work — not just sitting on top of your skin.
Your Plan Is Simple
No guesswork, no 12-step routine to overhaul. Just three steps between you and firmer, more radiant skin.
