Kiehl’s Cryste Marine Firming Serum is a concentrated firming serum that penetrates skin to soften the appearance of fine lines and wrinkles. The formula is made with criste marine–a naturally-derived botanical found aside the Mediterranean Sea–as well as padina pavonica and vitamin C glucoside.
It has a gel texture and feels like a hydrating serum. According to this article, criste marine has a rich cache of the “essense of youth” that delays aging. Also, the same article states that “The skin repair benefits of the plant stem cells of Criste Marine are accredited to their strikingly powerful affinity to the human skin cells. In particular, they work wonders in:
- improving skin elasticity and radiance
- promoting speedy wound healing
- expediting dermal metabolism
- preserving structural integrity of skin lipids
- reducing melanin (which causes freckles) formation
- initiating various skin protection functions”.
