Real results from real customers, mapped across time
Week 1
Peptides begin penetrating the dermal layer. Skin feels softer and more supple to the touch. The Hyaluronic Acid delivers immediate hydration dissolve cleanly with no residue, pilling or tightness.
Week 2
Fine lines soften. Skin tone becomes more even. Customers report a subtle glow. Skin looks less dull and tired and the kind of subtle shift where someone says "you look well" without knowing why.
Week 3
This is where the 30 signal peptides compound. Collagen and elastin production has been consistently triggered. Jawline looks more defined. Under-eyes look less hollow. Friends start asking what you've been doing.
Week 4
The face in the mirror matches how you feel again. Firmer skin, softer lines, visible lift without a single needle, filler or clinic visit. Just a serum that finally delivered what it promised.
Most copper peptide serums use GHK-Cu at 3 to 10 parts per million — a concentration so low it produces no measurable effect. BioGlo is 2% — roughly 200 to 700 times the concentration of most products on the market. The dose is the difference. It wasn't you. It wasn't the ingredient. It was the amount.
We had the formula tested by an independent third-party laboratory using HPLC — a method that confirms the exact molecular structure and concentration of GHK-Cu in the bottle. The Certificate of Analysis is available on this page.
Most customers feel skin is softer and more hydrated within the first week. Visible improvements in tone and texture typically begin around week 3–4. For firmness, elasticity, and reduction in fine lines, consistent use over 8–12 weeks delivers the most noticeable results. That's exactly why we offer a 60-day guarantee
