Genuinely visible results
Six weeks in and my skin looks noticeably firmer and more even. Feels luxurious to use — nothing like the drugstore peptide serums I've tried.

Complete your skincare routine with ULTIMATE SEAL Advanced Barrier Lock Moisturiser. Developed specifically to complement the ULTIMATE peptide serum collection, SEAL is the essential final step designed to lock in your copper peptide treatment while helping maximise hydration and support optimal serum performance. Applied after GHK-Cu 1%, GHK-Cu 2% or the Copper Tripeptide & Ectoin Advanced Repair Serum, SEAL forms a breathable moisturising barrier that helps reduce transepidermal water loss, seal valuable actives against the skin and create the ideal environment for prolonged hydration and enhanced peptide performance. Rather than simply moisturising the skin, SEAL has been precision formulated to work alongside advanced copper peptide technology. By helping maintain skin hydration and reinforcing the skin's natural barrier, it allows your ULTIMATE serums to remain where they are needed while leaving skin smoother, softer, firmer and more resilient-looking. Powered by Ceramides, Squalane, Sodium Hyaluronate and Vegetable Glycerine, this advanced formulation delivers long-lasting hydration while supporting barrier function without leaving a heavy or greasy finish. Manufactured using pharmaceutical-grade ingredients, SEAL reflects ULTIMATE's commitment to precision formulation, ingredient quality and scientific excellence.

The real deal
Pharma-grade credentials show. Clean formula, no fragrance, works with my retinol routine without irritation.

My barrier finally feels calm
Struggled with reactive skin for years. Introduced this slowly and within a month redness has dropped dramatically.

Best I've used
Tried several UK peptide brands — ULTIMATE is a clear step above. Considered packaging, professional feel, real results.
