Between back-to-back Zoom calls and staring at a screen all day, I started noticing something I couldn’t unsee — the constant squinting and screen glare were leaving fine lines around my eyes and forehead. I started applying Astera every night, and the difference is incredible. The copper peptide and hyaluronic acid combo has really helped firm up my skin, and those fine lines are fading fast. I also love that it’s completely non-greasy, so it soaks in fast and never feels heavy before bed.

Astera has been a total game changer for my skin. I’m 28, and my face had gotten so dry that I was starting to notice more fine lines and my skin just looked tired and dull. After using this serum, I can honestly tell a huge difference. My skin feels so much softer, smoother, and deeply hydrated. It goes on nicely, absorbs quickly, and has really helped bring my face back to life. I look and feel more refreshed, and my skin no longer feels dry and tight all the time. I truly could not recommend this copper peptide serum more.

After using this serum for a few days, I have to say I really enjoy it. It hydrates my skin and makes it plump. It moisturizes my face nicely, and it’s not greasy at all — which is great. Highly recommend this serum. For the price, it’s great.

I'm finally getting serious about my skin, but every active I tried before this left my skin dry, tight, and irritated. Astera changed that completely. What surprised me most is how hydrating it is — this isn’t just a treatment serum, it’s genuinely nourishing. I apply it every night (the spa headband has become part of the routine) and wake up to skin that looks plump and dewy, almost like it’s glowing from within. No irritation, no adjustment period — it just works. If you’re chasing that youthful bounce without dealing with harsh side effects, this copper peptide serum is worth trying.

I’ve been trying to cut back on harsh chemicals in my routine, and Astera has honestly exceeded my expectations. The moisture it gives my skin is noticeable right away — no greasy residue, just a soft, healthy-looking glow. For the price, the quality really stands out. My skin feels incredibly soft, and this has quickly become exactly what my routine was missing :)
