Customer Reviews
So happy with my order!
Oh my goodness, I just received my Skin Signals Solution and a Folligen for Hair! I'm so excited to start using these. The website was super easy to navigate, and my package arrived in just a few days, which was awesome. Everything was packed carefully, and the products look really high quality. I'm already telling my sister about this place. Can't wait to see the results!
Got my serums, all good
Yeah, so I ordered some GHK-Cu Copper Peptide Serum and a LacSal Serum from Skin Biology last week. It was pretty straightforward. The site wasn't hard to figure out. My package showed up today, like 5 days after I ordered, which is decent. Everything looked fine inside, nothing broken or anything. Just got what I wanted, no fuss.
Decent products, slow shipping
I ordered the GHK Luxury Copper Peptides and a Retinol Cream. The products themselves seem high quality, and I like the texture of the cream. My only real gripe was the shipping time; it took almost 8 days to reach me in Florida, which felt a bit long. Customer service was responsive when I inquired about the delay, though. The packaging was secure, and everything arrived intact. I'm happy with the items, just wish delivery was a little quicker.
Quick delivery, good product
Ordered Super GHK-Cu Cream. Arrived fast. Product was as described. No issues. Will buy again.
Good value with bulk discount
I was looking for a good deal on copper peptides and found Skin Biology. I bought the Super Cop 2X and also grabbed a GHK-Cu Eye Cream because there was a bundle offer. The savings were noticeable, especially compared to other brands. Shipping took about a week to get to me in Oregon, but the products arrived well-packaged. Overall, I feel like I got a solid amount of product for my money.

Share tips, ask questions & help fellow shoppers save more
hey, was thinking of trying the Super Cop 2X. Does anyone know how long shipping usually takes to, like, California?
What's the return policy like? just in case something doesn't work out.
can you use more than one coupon code at checkout? like a first time buyer discount and something else?
i'm thinking about trying some of their hair signals stuff but worried about irritation. my scalp is super sensitive. anyone else with sensitive skin use their products?
is skin biology actually legit? saw some stuff online and just want to make sure before I drop money on the GHK-Cu serum.
Has anyone compared The Ordinary's copper peptides to Skin Biology's? is the difference worth the price jump?
