Noticeably smoother skin

I’ve been using this for about 3 weeks and my skin texture feels much smoother, especially on my forehead and around my mouth. It absorbs fast and doesn’t interfere with the rest of my routine. No irritation at all, which is rare for me. I’ve been using this for about 3 weeks and my skin texture feels much smoother, especially on my forehead and...

Finally something gentle that works

Vitamin C started being too harsh for my skin, so I tried this instead. My skin looks calmer and more even, and I like that it doesn’t sting or tingle. Definitely staying in my routine.

Skin feels firmer

I’m in my early 50s and mostly bought this for sagging around my jawline. It’s not a miracle, but after a month my skin definitely feels firmer and looks healthier overall. Great texture and easy to use. I’m in my early 50s and mostly bought this for sagging around my jawline. It’s not a miracle, but after...

Good results, just moisturize after

I like this serum a lot. It makes my skin feel tighter and smoother, but I do need to follow with a good moisturizer or it feels a bit dry. Once I do that, it’s perfect. I like this serum a lot.

Simple and effective3

I appreciate that this isn’t overloaded with ingredients. It absorbs quickly and layers well under moisturizer and sunscreen. My skin just looks better since I started using it.

Subtle but real improvement

This isn’t one of those products that changes your face overnight, but after a few weeks I noticed my skin looks softer and more even. It feels like a smart long-term product.

Frequently Asked Questions

Most people notice their skin feels smoother and firmer within the first 1–2 weeks. More visible improvements in texture and firmness typically appear after 3–4 weeks of consistent use.

Yes — but not at the same time. Most people use copper peptides in the morning and retinol at night, or alternate days. This helps avoid irritation and keeps your routine balanced.

Yes. This formula is fragrance-free and designed to be gentle. If you have very sensitive skin, we recommend starting 3–4 times per week and increasing as tolerated.

Copper peptides can feel slightly tightening on some skin types. We recommend following with a moisturizer to keep skin comfortable and hydrated.
