Our story
365 days a year, we think about one thing.
For those who are truly devoted to beautiful skin, RENOPTI is devoted to collagen — refining every detail to create a difference you can see and feel.
The science
What's inside, and why.
Our collagen is low-molecular-weight hydrolyzed marine peptide, sourced from wild-caught deep-sea fish off Jeju Island. We chose this form specifically because it absorbs more efficiently than bovine or standard collagen — your body actually gets the dose on the label.
Every lot is third-party tested for heavy metals, microbes, and peptide molecular weight. Every formula is reviewed by a board-certified dermatologist. Every detail — down to how a stick tastes dissolved in cold water — gets refined, again, until it's right.
FAQ
What people ask us most.
How long until I see results from the collagen sticks?
Most of our customers notice visible changes in skin bounce and hydration between two and four weeks of daily use. Fine lines and texture take closer to eight to twelve weeks — the clinical window where collagen synthesis actually catches up with the dose.
Are these safe during pregnancy?
Our Synerup collagen sticks and Signature Mask do not contain retinoids or restricted actives. We still recommend running any new supplement past your OB before starting.
Where do you source your collagen?
Our marine collagen is low-molecular-weight hydrolyzed collagen peptides from wild-caught deep-sea fish, processed in a GMP-certified facility in Korea. Each lot is third-party tested for heavy metals and purity.
