“Absolutely Amazing


This serum is super silky.

I use the vitamin C first, then put this on, and the peptides work like a charm. My skin is so smooth. And glowing.

I love how fast it is absorbes and doesn’t leave a greasy after film.

I also like that I am able to do a full face of makeup and it doesn’t cake.”

– Monica (Open Formula client)

Reduce the look of lines & wrinkles

10% peptides support collagen – the protein that makes up 75% of your skin and keeps it firm and bouncy.

Plumps the skin

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
  • Like collagen production – a protein that makes up 75% of your skin, giving it the smooth, firm and bouncy look
“Matrixyl 3000 significantly reduced [the appearance of] wrinkles, wrinkle depth, and wrinkle density”
-Croda Research
“Visible smoothing in [the look of] deep wrinkle… particularly effective against expression lines by relaxing facial muscles.”

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.

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

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
