Which ingredients make this serum a good fit for dry skin?
Glycerin and butylene glycol help quench dryness and flakiness, while peptides like acetyl hexapeptide-8 and palmitoyl tripeptide-1 support your skin barrier and plump dry skin. Additional peptides like palmitoyl tetrapeptide-7 further enhance these firming and moisturizing benefits to ensure your skin stays soft and smooth.
What do Collagen Peptides do for dry skin?
Collagen peptides help improve dry skin by boosting hydration and keeping skin soft and smooth over time. Taking them daily helps lock in moisture and supports your skin barrier so it holds onto water better.
What does Argireline do for dry skin?
Argireline helps smooth out fine lines and reduce skin roughness when applied twice a day. It may also improve overall hydration, though it works best when paired with ingredients that deeply moisturize dry skin.
American Journal of Clinical Dermatology, 2013Journal of Cosmetic and Laser Therapy, 2013
Where does this serum go in a skincare routine for dry skin?
This serum goes in your evening routine, applied after cleansing and before your moisturizer. Putting it in the evening keeps things simple and helps avoid any extra sun sensitivity.
Can I use this serum with retinol, and in what order?
You can use this serum with retinol by applying the serum first to keep your dry skin hydrated and comfortable. This combination is unlikely to cause irritation because the serum helps support your skin barrier while delivering deep moisture.
How often should I use this serum?
This serum is a great fit for your dry skin and is used in the evening routine. Applying it daily helps tackle dryness and flakiness while supporting your skin barrier with peptides and glycerin.
Journal of Cosmetic Dermatology, 2020Health Science Reports, 2021
Can this serum clog pores, cause breakouts or purging for dry skin?
This serum is unlikely to clog pores, cause breakouts, or lead to purging on dry skin. It has a very safe profile with gentle, soothing ingredients and no harsh components that typically trigger irritation or breakouts.
Can I use this serum around the eyes or on my body?
You can use this serum around the eyes, where skin is thin and benefits from firming peptides, but using it on the entire body may be impractical due to the small bottle size. It is unlikely to cause irritation and helps improve fine lines in delicate areas safely.
