Copper Elixir - Advanced Youthful Skin Face Serum - GHK-Cu (Copper Peptides), EGF (Epidermal Growth Factor) - Science-Backed - Witch Hazel, Grapefruit Oil, Shea Butter - .50 fl oz (15mL)

I'll be honest: I was skeptical going in. Copper peptide serums have exploded in popularity on social media, and it's hard to separate hype from substance. After using Mirror Skin's Copper Elixir for about six weeks, here's where I've landed. What it is: A lightweight serum built around 1.25% GHK-Cu (copper tripeptide-1) and EGF (epidermal growth factor), along with supporting ingredients like witch hazel, apple stem cell extract, shea butter, and grapefruit oil. It has a distinctive blue tint — that's the copper peptide itself, and it's actually a good indicator that the product contains a meaningful concentration of GHK-Cu rather than a token amount. What I noticed: The first week, not much. By week two, my skin started looking noticeably brighter and more "alive" — not in a dramatic before-and-after way, but like my complexion had a healthy, well-rested quality to it. By week four, I noticed improved texture and a subtle tightening effect, particularly around my jawline and forehead. Fine lines looked softer, not erased, but definitely diminished. The serum absorbs quickly and doesn't leave a greasy residue, which made it easy to layer under sunscreen in the morning and moisturizer at night. What I like: The ingredient list is thoughtfully composed. GHK-Cu is backed by decades of research suggesting it can promote collagen production, support wound healing, and encourage skin to behave in a more youthful way at the cellular level — not just cosmetically mask aging. The addition of EGF and apple stem cell extract rounds out the formula nicely. The liposomal delivery system is a smart touch that should help the actives penetrate deeper rather than just sitting on the surface. I also appreciate that the brand is transparent about the actual GHK-Cu concentration (150mg per 15mL bottle), which is more than many competitors disclose. Where it falls short: The bottle is tiny. At 15mL (0.5 fl oz), using a full dropper per day gives you roughly a 30-day supply, and at this price point, that cost-per-use adds up quickly. You can stretch it to 60 days with lighter application, but then you may be underdosing the actives. I'd also note that the ingredient list includes alcohol fairly high up, which could be a concern for people with very dry or sensitized skin — though I personally didn't experience any irritation. Finally, results are cumulative and slow-building. If you're someone who needs instant gratification from a skincare product, this isn't it. The brand itself says optimal results come at the 2–3 month mark, and based on my experience, that tracks. Younger users with minimal skin concerns will likely see more modest improvements than those with mature skin who have more visible signs of aging to address. Bottom line: Mirror Skin Copper Elixir is a legitimate copper peptide serum with a well-formulated, research-backed ingredient profile. It delivers on the promise of improved radiance, texture, and subtle firming — it just asks for patience and a willingness to invest in a small-but-potent bottle. If you've been curious about GHK-Cu and want a product that actually contains a verified, meaningful concentration of it, this is a solid pick.

Fantastic. I use this product with Red Light Therapy and find the effects of glowing skin amplified.

This copper peptide serum delivers a lovely boost of hydration while helping improve my skin’s texture and firmness. Over a few weeks of morning and night use, I noticed that fine lines looked softer and my skin appeared more radiant and plump. The lightweight formula absorbs quickly and layers beautifully under moisturizer or sunscreen without feeling sticky. I also appreciate that it doesn’t irritate even sensitive areas around my eyes. It feels like a gentle but effective step that enhances my overall skincare routine. For anyone aiming for smoother, more resilient skin, this is a strong everyday pick.

I lik this product I use it every now and then though but it does make my skin look nice and shiny! Very moisturizing!

My wife is really liking this serum so far, so she asked me to leave a review. The blue color of the serum is cool and it feels very lightweight. It absorbs super fast, doesn't leave any residue or sticky feeling, and doesn't dry out skin. The bottle and box look really sleek, stylish and high-quality. It is a bit pricey for the size, but she’s hoping to see good results with continued use. Would recommend if you're looking for a serum that feels like nothing on your skin.
