Turn Back Time With Copper Peptides for Skin For a Firmer, More Youthful Appearance
This Palmitoyl Peptides serum pairs Palmitoyl Tripeptide-1 and Palmitoyl Tetrapeptide-7, a dual-peptide complex known for supporting skin cell communication and minimizing the appearance of fine lines. We've included GHK-Cu (copper peptide complex) because it can support the skin's natural collagen pathways. Potential benefits of our copper peptides for face:
- Supports Skin Firmness: GHK-Cu copper peptide supports skin's natural collagen pathways for firmer-looking skin appearance
- Reduces Appearance Of Fine Lines: Palmitoyl Tripeptide-1 and Palmitoyl Tetrapeptide-7 help improve how fine lines and skin texture appear over time
- Enhances Skin Appearance: Helps retain moisture and even out skin tone for a refreshed, healthy-looking complexion
Our copper peptide serum is formulated to match published research, and customers are seeing visible improvements in skin firmness and fine lines in as little as 1-2 weeks. Weeks 4-8 are when you'll notice the more dramatic transformation in your skin's appearance, though.

Frequently Asked Questions
Are copper peptides good for the face?
Yes, and there’s plenty of research to support using copper peptides for skin. These formulas can encourage firmer-looking skin and a smoother texture.
What do copper peptides do for your skin?
They’re signaling peptides that help skin cells communicate effectively. This translates to improvements in the appearance of fine lines, elasticity, and overall skin tone over time.
What skin types react badly to copper peptides?
None! Copper peptides are generally considered safe for all skin types and ages. Although copper peptides for face are most commonly associated with mature skin concerns, they can be beneficial for anyone looking to keep their skin firm and supple, preventing early signs of aging.
Can you put moisturizer over copper peptides?
Yes - in fact, you should. It’s just important to make sure you’re following the proper order. Copper peptides go on the face first, and need to be given 30-60 seconds to absorb. THEN you can layer on your moisturizer or other skincare ingredients.
How long does it take to see results from copper peptides for face?
You might notice early signs of improvement within the first few weeks. Most users start to see more dramatic transformations around 4-8 weeks, though. Give it a full 12 weeks before making any decisions about whether or not to continue use. Like copper peptides for hair, patience and consistency are key!
Can I use copper peptides daily?
You need to use them daily for the best results. Consistency is key. A lot of our customers actually use copper peptides on the face twice daily.
What should you not mix copper peptides with?
There aren’t any ingredients known for causing adverse reactions with copper peptides for skin. You should apply our Face Tonic first, though, and let it absorb for up to a minute. Then you can follow up with other products like hyaluronic acid, vitamin C serum, or moisturizer.
Can I use copper peptides for face if I have sensitive skin?
Yes. our formula is free of common irritants like parabens, sulfates, silicones, or artificial fragrances. However, as with any new skincare product, we recommend patch testing on a small area first. You may want to ask a dermatologist before using our copper peptides for skin if you have a known skin condition, too.
Are copper peptides better than retinol?
Not necessarily better - different. Retinol targets surface renewal, while copper peptides are often used for firmness and conditioning. There’s room for each in your routine.
When do I actually use copper peptides for skin?
We recommend applying twice a day - first thing in the morning and then again before bed. Or, you can simplify the routine with just nightly application. What matters most is you’re using copper peptides on your skin daily.
