What do Collagen Peptides do for sensitive skin?
Collagen peptides help improve hydration, elasticity, and barrier strength for sensitive skin. They may also support a calm, smooth feel by keeping the skin well-moisturized and reducing dryness.
Skin Pharmacology and Physiology, 2021Journal of Medicinal Food, 2022
What does Argireline do for sensitive skin?
Argireline is unlikely to cause irritation and is sometimes found in products designed to calm reactive skin. Studies show it helps smooth the look of wrinkles and decrease skin roughness when used consistently.
American Journal of Clinical Dermatology, 2013Pharmaceuticals, 2021
Where does this serum go in a skincare routine for sensitive skin?
This serum goes in the evening routine after your toner and before your moisturizer. Placing treatments in the evening provides extra safety around sun exposure and keeps your routine simple.
Can I use this serum with retinol, and in what order?

How often should I use this serum?
This serum is used in the evening as part of your routine. Daily application helps keep your sensitive skin hydrated and smooth while supporting elasticity.
Journal of Cosmetic Dermatology, 2020Health Science Reports, 2021
Can this serum clog pores, cause breakouts or purging for sensitive skin?
This serum is unlikely to clog pores, cause breakouts, or lead to purging on sensitive skin because it contains gentle hydrating ingredients like glycerin and soothing peptides without any harsh additives. It is formulated to keep skin calm and hydrated while supporting firmness without heavy oils that typically trigger breakouts.
