GOOD QUESTIONS

A little clarity
before you choose.

What does a peptide serum do?

Peptides are short chains of amino acids. In skincare, they are used in formulas focused on the look of firmer, smoother skin. A peptide serum is a lightweight, concentrated step applied after cleansing and before moisturizer. Peptides in skincare, explained ↗︎

Will a peptide serum firm my skin?

It can support the look of firmer, smoother skin with consistent use over 8–12 weeks, but no serum lifts skin like a professional treatment. Skin firming serums, explained ↗︎

Are copper peptides and GHK-Cu the same thing?

GHK-Cu is the best-known copper peptide. On ingredient lists it appears as Copper Tripeptide-1 (or Tripeptide-1 Copper), and both serums contain it. Copper peptides guide ↗︎

Which serum should I choose?

Start with Advanced Serum (1% GHK-Cu + 1% SNAP-8) if you are new to peptide serums or want the everyday price. Choose GLO Serum ULTRA (3% + 3%) if you already use a serum and want a high-potency, lightweight step. Use one serum, not both: they share the same peptide pair at different strengths. Take the 1-minute quiz ↗︎

How do I choose a peptide serum?

Look for recognizable peptides by their official names, a full ingredient list, a texture you will use every day, and realistic claims. Then compare the price per week of use. How to choose a peptide serum ↗︎

When should I apply a peptide serum?

After cleansing, morning and evening, before moisturizer. In the morning, always finish with sunscreen. Skincare routine order ↗︎
