Peptides are one of the most misunderstood ingredient categories in beauty. They’re everywhere on ingredient lists, rarely explained, and frequently lumped into vague “anti-ageing” claims that don’t explain what they actually do.
Here’s the honest explanation — and why they’re in the Glow Base Radiance Serum.
What Peptides Actually Are
Peptides are short chains of amino acids — the building blocks of proteins. In skin, the most important protein is collagen, which gives skin its structure, firmness and the ability to bounce back. Collagen is constantly being produced and broken down, and as we age, breakdown outpaces production.
Peptides work by sending signals to skin cells. Specifically, the peptides we use — Palmitoyl Tripeptide-1 and Palmitoyl Tetrapeptide-7 — signal fibroblasts (the cells responsible for collagen production) to produce more collagen and reduce inflammation simultaneously.
The Specific Peptides in the Glow Base Radiance Serum
Palmitoyl Tripeptide-1 mimics a fragment of collagen that tells skin cells collagen has been broken down and new production is needed. It’s sometimes called a “messenger peptide” — it doesn’t directly add collagen, it sends a signal that triggers the skin’s own production mechanism.
Palmitoyl Tetrapeptide-7 works alongside it by reducing the production of interleukins — inflammatory messengers that, when elevated, accelerate collagen breakdown. Together, the two peptides create a dual action: more collagen produced, less collagen broken down.
What This Means in Practice
In the short term: peptides contribute to a plumper, firmer surface appearance that makes fine lines less obvious.
In the long term (8–12 weeks of consistent daily use): measurable improvements in skin density and elasticity.
These are not cosmetic effects that disappear when you stop. Unlike some ingredients that work only while they’re on skin, peptides trigger biological processes that continue after application.
Why Peptides + Niacinamide + Vitamin C Work Together
The Glow Base Radiance Serum combines all three because they address different parts of the same outcome: brighter, smoother, firmer skin.
Niacinamide addresses tone (brightening, pore refinement, barrier strengthening). Peptides address structure (collagen support, firmness). Vitamin C addresses oxidative stress (the environmental damage that accelerates both dullness and collagen breakdown).
Each works independently. Together, they address the same skin goal from three different biological directions.
That’s why the Glow Base Radiance Serum looks different on skin than a single-active product. It’s not one thing working — it’s three things working together.
