Skincare has a maximalism problem. Ten-step routines make great content, but they make it almost impossible to know what's working, and layering many actives often leaves skin irritated rather than improved.
We designed Cuprine as a complete routine in three steps: serum, cream, and tallow balm. Each product has a distinct job, and they're formulated to layer without conflict.
The serum delivers GHK-Cu deep into fresh, clean skin. The cream hydrates, firms and locks it in. The tallow, used at night, seals everything under a nutrient-rich layer while you sleep, the hours when skin does most of its repair work.
The most important ingredient, though, is consistency. GHK-Cu works with your skin's own regeneration cycles, which take weeks, not days. Commit to the ritual morning and night, and judge the results at week twelve. We think you'll be glad you did.
