Klara Skincare has always blended nature’s wisdom with scientific rigour. To prove our Anti-Wrinkle Peptide Day Cream and Pep-Stem Yellow Serum truly work, we asked independent experts at Makrolife Biotech in Germany to run lab tests on human immune cells. The results show our products switch on the skin’s own repair and defence systems—so you get firmer, smoother, more resilient skin.
