10% peptides support collagen - the protein that makes up 75% of your skin and keeps it firm and bouncy.
As the skin loses collagen, it "deflates" and the texture shows wrinkles. The collagen peptide moisturizer helps plump up the skin to improve the look of skin texture.

How peptides work
- Peptides are “messengers” that send signals to the skin to turn on and off certain processes

I’ve been using this for my smile lines. And I see an improvement. Like the texture. It goes well under makeup. Nice serum overall.
I prefer the collagen peptide serum over the cream. It’s lighter and absorbs faster. I’m in my 50s and recently discovered peptides - they are great.
It’s one of the best serums I’ve used. Leaves the skin nice and moisturized. I use the retinoid afterwards, and don’t even need a cream. In the morning, my skin is soft and smooth.
It’s a staple in my skincare routine now. I also use the vitamin C and the SPF from OPen Formula in the morning. My skin looks so glowy. I’m even getting compliments.
I think this is my new favorite skincare product. I use 5-6 other Open Formula products and they are all very nice. But this one just leaves my skin feeling so nice.
Good product. I wish they had a larger size available
It is great for my neck. I won’t say it’s like a ‘neck lift’ but it’s pretty damn close for a skincare product
I totally recommend this product. The lines on my forehead and around my mouth look a lot better after a few weeks. And the skin on my neck feels more firm
It’s a very thin serum, but still nice and moisturizing. I use the squalane in the dry winter months for an extra moisture boost. But in spring/summer, this one is perfectly sufficienrt
It’s a good product. They recommended it to me for saggy skin on the neck. And it’s done a good job
