Klara's
New Pep-Stem Yellow Serum
A super absorbent serum, which delivers stem cells from a rare Swiss apple deep into your skin tissue.
New Improved Formula of Klara's Rejuvenating Serum
Powerful Peptides. Plant Stem Cells. Visible Radiance.
Reveal smoother, firmer, and more radiant skin with Klara’s Pep-Stem Yellow Serum, a luxurious blend of biomimetic peptides, plant stem cells, and botanical extracts. This high-performance serum targets the early signs of ageing, boosts skin regeneration, and improves skin tone and elasticity — naturally and effectively.
Formulated with: 🌿 Acetyl Hexapeptide-3 (Argireline®) – A powerful peptide that helps reduce the appearance of expression lines by relaxing facial tension, often called “botox in a bottle.”
🌱 Phytocelltec™ Malus Domestica (Apple Stem Cells) – Protects skin longevity and promotes regeneration at the cellular level.
💧 Hyaluronic Acid & Hydrolysed Collagen – Deeply hydrate and plump the skin, improving firmness and reducing fine lines.
🌸 Rose Water, Cucumber Juice & Aloe Vera – Soothe, calm, and tone the skin for a fresh, healthy glow.
🧬 Peptide Complex (Palmitoyl Oligopeptide & Palmitoyl Tetrapeptide-7) – Stimulates collagen and elastin production, helping to firm and smooth the skin over time.
🌼 Niacinamide & Panthenol – Brighten dull skin, reduce pigmentation, and strengthen the skin barrier.
🌿 Sea Buckthorn, Rosemary & Lotus Extracts – Provide antioxidant protection and support skin healing.
Perfect for all skin types, especially mature, sensitive, or dehydrated skin, this serum absorbs quickly and leaves no sticky residue — just smooth, luminous skin ready for the day.
