Power Up Silk Peptide Concentrate for Hydration and Fine Lines is a versatile, ultra-light serum designed to blend seamlessly into any leave-on skincare step. It features SF-VII®, a specialised silk-peptide complex developed by tissue-repair researchers, combined with niacinamide, hyaluronic acid, and ceramides to support skin hydration and overall appearance. When added to your existing routine, this concentrated serum helps soften the look of fine lines, enhances radiance, and promotes a smoother, more comfortable skin feel.
The formula is free from oil, fragrance, and parabens, giving you a clean way to personalise your daily skincare. Just one to two drops added to your moisturiser, serum, or treatment step offers an easy method to elevate hydration and support a healthier-looking complexion.
Power Up Silk Peptide Concentrate for Hydration and Fine Lines uses a blend of silk peptides in different molecular weights to target multiple layers of the skin, giving stronger and more visible results. SF-VII® has shown in in-vitro studies that it stimulates keratinocyte and fibroblast activity, which supports collagen production and healthier skin structure. The formula brings together hyaluronic acid, niacinamide, ceramides, and cholesterol to reinforce the skin barrier and maintain long-lasting hydration, clarity, and resilience. With no oil or fragrance, the concentrate mixes easily with any leave-on product, helping you enjoy smoother, stronger, and more radiant skin.
THIS IS SILK was founded by Sonal Keay, whose own experience with a rare skin condition led her to uncover silk’s remarkable regenerative properties. Her research into medical literature inspired her to work with leading scientists to transform silk into high-performance skincare, culminating in the creation of SF-VII®, a UK-developed peptide crafted from ethically sourced silk. Rooted in science, heritage, and sustainability, the brand focuses on evidence-based formulations that support repair, renewal, and long-term skin health. Through this thoughtful approach, THIS IS SILK helps you experience smoother, calmer, and more resilient skin every day.
