Our 90-day promise

You have bought skin products before that did nothing. You waited, you checked the mirror, and nothing changed. So we are not going to ask you to just trust us. Here is exactly how the promise works.

  1. Give it the full 90 days.Copper peptides do not work overnight. Your skin starts to calm down in the first week or two, but the real change — firmer, thicker, stronger skin — builds up slowly and peaks at about 90 days. That is why we give you 90 days instead of 30.
  2. Take a photo on day one.Snap a quick photo of your face before your first drop. Then use BioGlo at night, every night. On day 90, take another photo in the same spot and the same light, and put the two side by side.
  3. Do not like what you see? You do not pay.If day 90 comes and your skin does not look different — or you just do not feel like yourself again — then we have not earned your money.
  4. Getting your money back is easy.Email us at support@bioglo-toronto.com with your order number. We put 100% of your money back on your card. No phone calls, no forms, and you never have to mail the bottle back. Keep it, even if it is empty.

COMMON QUESTIONS

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.
Can I use this with retinol or vitamin C? Retinol yes. Just not on the same night. Use BioGlo one night, retinol the next. Simple.Vitamin C no. This one is important. When GHK-Cu and vitamin C mix they create a chemical reaction that breaks down both ingredients. You end up with a weaker serum and a wasted vitamin C. Neither one does its job.The fix is easy. Use BioGlo at night. Use vitamin C in the morning. Never in the same routine.Most copper peptide brands never tell you this. That's because they have so little GHK-Cu in their formula it doesn't matter. Ours has 2%. It matters.
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 90-day guarantee
The Ordinary Buffet + Copper Peptides is 1% GHK-Cu in a multi-peptide blend. NIOD CAIS retails at $90. BioGlo is 2% single-active, independently verified by HPLC, at $49.99 CAD. You're not paying for a name. You're paying for the dose and the proof.
Yes. Our formula includes panthenol and allantoin specifically to support sensitive skin. Copper peptides are generally very well-tolerated. We recommend patch-testing on your inner arm for 24 hours before full application. If you have a diagnosed skin condition, consult your dermatologist first.
2–3 drops is all you need for your full face and neck. Apply to clean skin before moisturizer. The serum works morning and night — morning before SPF, evening before your night cream. One 30ml bottle typically lasts 6–8 weeks with twice-daily use.
