Our storyShop the GHK-Cu Series
Where luxury skincare meets powerful ingredients
PB Cosmetics is a UK skincare brand built around one remarkable ingredient: GHK-Cu, the copper peptide. We wanted skincare that felt as luxurious as it was considered — formulas that look after the skin's barrier, deliver deep hydration and help skin look firmer, smoother and more youthful, without the exaggerated promises.
The result is the GHK-Cu Series: five products designed to work together as one simple ritual, morning and night. Every formula pairs Copper Tripeptide-1 with a supporting complex of peptides, niacinamide, hyaluronic acid, ceramides, squalane, panthenol, beta-glucan and collagen — finished in navy glass and gold, with textures worth lingering over.
Our philosophyHow to use the series
Science. Luxury. Results.
Three words guide everything we make. Science — every product is built around GHK-Cu, a well-researched cosmetic copper peptide, supported by well-established hydration and barrier ingredients. Luxury — navy glass, gold accents and textures that make every step feel like a moment. Results — skincare designed to help your skin look firmer, smoother, plumper and more radiant, with consistent use, morning and night.

The people behind PB
A small family business, UK based
PB Cosmetics is run by the same two people behind Pure Bronzing — a mother-and-son team. We started out making the products we couldn't find on the shelf, and skincare is our next chapter — built with the same care, and the same refusal to settle for products that don't do what they promise.
That care goes into every order, too. We personally pack each parcel and answer every message ourselves, and we genuinely care about every person who chooses us. When you shop with PB Cosmetics, you're supporting a real family with a real passion for helping people feel confident in their own skin.
