Retinol and peptides get bundled together in a lot of formulas, but they're not doing the same job.
Retinol is a derivative of vitamin A. It's one of the most studied ingredients in skincare for supporting the appearance of smoother, more even-looking skin over time — which is why it's almost always a nighttime step, since it can increase sun sensitivity.
Peptides are short chains of amino acids — the building blocks proteins are made from. In skincare, certain peptides are used to support the skin's own structural proteins, working alongside actives like retinol instead of replacing what retinol does.
Putting them in the same formula isn't about doing more — it's one product covering two different mechanisms instead of two separate steps.
How to use it
Apply 3–4 drops to clean, dry skin at night. Follow with a moisturizer. Because retinol can increase photosensitivity, use sunscreen the next morning — no exceptions.
What not to expect
Retinol works gradually. Most people don't see meaningful texture change overnight — give a formula several weeks of consistent use before deciding whether it's working for you.
