Ourglax Blue Copper Peptide GHK-Cu Complex Advanced Firming Serum

This GHK-Cu serum has been a pleasant and effective addition to my evening routine. My skin feels stronger and more hydrated after four weeks and the improvement in firmness and complexion evenness is building consistently. Four stars and pleased.

I started this serum to address early firmness loss and it is doing a good job of that so far. After three weeks my skin feels firmer to touch and my complexion looks slightly more refined. Four stars I want to see the full results after two months of consistent use.

Good copper peptide serum that works gradually and consistently. I can feel my skin is more elastic and bouncy after four weeks and I can see slight improvement in my skin tone and texture. Giving four stars while I continue to build on the results.

Okay copper peptide serum that provides decent hydration and a pleasant application experience. The GHK-Cu results in terms of visible firming and complexion improvement have been quite mild after a month. Fine for hydration but not the transformation I expected.

This GHK-Cu serum is gently but consistently improving my skin quality. After a month I can feel the difference my skin snaps back more quickly and my complexion looks more radiant and even. Good product with real results.

The science behind GHK-Cu is what drew me to this serum and the results have more than confirmed the research. After six weeks my skin is measurably firmer, my fine lines are softer and my complexion has a luminosity and evenness that makes me genuinely happy every time I see my reflection.

I have sensitive post-menopausal skin that loses firmness quickly and reacts badly to most actives. This GHK-Cu serum has been completely gentle while delivering real firming and brightening results. After eight weeks my skin looks years younger and I have experienced zero irritation.

The firming effect of this copper peptide serum is something I can actually feel. My skin springs back differently now more elastic and resilient. Alongside the tactile improvement the visual results are real too. My face looks more contoured after six weeks and my friends have noticed.

My main concern was the loss of firmness in my neck and lower face. This GHK-Cu serum has addressed both areas more effectively than anything I have tried. After eight weeks my neck looks tighter, my jawline is more defined and my skin has a resilience that genuinely encourages me.

I have been using this serum for five weeks and the improvement in my skin quality is real and consistent. My face looks slightly more lifted, my skin feels firmer to touch and my complexion is more even. Good product with real potential.

My dermatologist mentioned GHK-Cu as an ingredient she wished more people knew about. After six weeks of this serum I completely understand why. My skin is genuinely firmer, my fine lines are softer and my complexion is more even and radiant. It is the real deal.

Mixed feelings after six weeks of consistent use. The serum is pleasant to apply and my skin does feel hydrated but the visible improvement in firmness and skin tone I was hoping for has been very mild. Good formula but not outstanding results for me.

The blue colour of this serum is unlike anything in my skincare collection and the formula is equally distinctive. It absorbs beautifully without any tackiness and the GHK-Cu clearly gets to work overnight. After six weeks my skin looks years younger and my friends have all asked what I changed.

This GHK-Cu serum has been consistent in delivering good hydration and genuine improvement in skin firmness and texture over a month. My fine lines look slightly softer. A good everyday copper peptide serum at a reasonable price.

This serum has not delivered on its GHK-Cu promises for me. After five weeks of consistent use my skin looks the same. No visible firming, no brightening, no improvement in fine lines. The texture is fine but the results are absent.

Good copper peptide serum that is delivering real gradual results. My skin feels firmer and more hydrated after a month and I can see my complexion becoming more even and radiant. Four stars — the results are building consistently and I am pleased.

My skin feels genuinely more resilient and springy after a month of this GHK-Cu serum. The blue formula absorbs perfectly and my skin looks more even and radiant every morning. Good purchase that I will definitely repurchase.

I have tried expensive clinical copper peptide treatments and this serum delivers comparable results at a fraction of the price. After two months my skin firmness, texture and tone have all improved measurably. The GHK-Cu concentration in this is clearly effective and well-formulated.

I notice a real difference on the mornings after I have used this serum. My skin looks firmer and more refreshed. After a month the cumulative improvement in texture and tone is becoming clearly visible. Four stars — keen to see full results at two months.

Good serum for targeting early signs of ageing. My skin looks slightly more contoured after four weeks and feels more resilient. The copper peptide formula is clearly effective. Would recommend and will repurchase when this bottle runs out.

Good value copper peptide serum with a well-made formula and genuine results over time. My skin is noticeably firmer and my complexion is more even after a month. Happy with this purchase and would recommend to anyone interested in GHK-Cu.

I gifted this to my sister who has mature skin and she called me genuinely excited after three weeks. Her skin looked firmer, her fine lines looked softer and her complexion was more radiant. She said it was the most effective serum she had ever used. That endorsement is better than any review.

It is an okay serum. Nice texture, gentle formula and real hydration. The visible firming and complexion improvement I was hoping for from GHK-Cu have been quite mild after five weeks of consistent use. Decent but not the results I expected.

My skin has responded well to this GHK-Cu serum. After a month it feels stronger, looks more even and has noticeably better hydration and firmness. I am giving four stars because I want to see if the results keep improving with another month of use.

I have been using this GHK-Cu serum for a month and the results are more subtle than I expected. My skin does feel slightly more hydrated but the visible firming and brightening effect that drew me to copper peptides has been quite mild for my skin type so far.

Real improvement in skin firmness and texture with consistent use over a month. My face looks slightly more contoured and my skin feels more springy. Four stars — I want another month to see how far the results go.
