SERU was built on one idea.
Most skincare brands spend more on marketing than on the formula inside the bottle. Trace amounts of active ingredients dressed up in clinical language. Fifty ingredient lists where the hero ingredient sits at the bottom. Products that look good on a shelf and do very little on your skin.
The science behind SERU
GHK-Cu is a copper tripeptide that occurs naturally in human plasma. At 20 your body produces it abundantly. By 35 production has dropped significantly. By 60 it is a fraction of what it was. GHK-Cu is responsible for signaling your skin to produce collagen and elastin - the structural proteins that keep skin firm, smooth and resilient.
At 340 Daltons it is small enough to penetrate the skin barrier and reach the dermis where collagen is actually built. Most topical ingredients never get there.
Matrixyl 3000 works differently. It mimics the collagen fragments that naturally signal your skin to produce more. Two completely separate collagen signals. One formula.
The result is not overnight. It is not a filter. It is real structural change that builds over 8 to 12 weeks and compounds with consistent use.
