Laneige Cream Skin Cerapeptide Refiner Versus Chanel N°1 de Chanel Revitalizing Serum

A separate study found the flower extract had solid antioxidant activity and reduced the reactive oxygen species that urban air pollution triggers in skin cells.

Newer work also points at anti-aging and calming effects:

One 2025 paper tied the extract and its component hyperoside to collagen III and elastin production plus better skin-barrier protein expression. A mouse study on eczema-like skin found four weeks of topical camellia extract reduced inflammation and itch-related markers.

Just know that most of these studies are cell-culture and animal work and not human trials. For now, it's best to treat it as a nice supporting antioxidant rather than a headline active.

At this time, there's no published regulatory use-level for this specific ingredient; suppliers usually sell it as a water/glycerin-based extract used in the low single-digit percent range.

There's no published contact-allergy case reports for this ingredient but as with any botanical, a patch test is sensible if you react to plant extracts generally.

Your skin makes glycerin on its own (mostly from sebaceous oil breakdown) and shuttles it to your outermost layer of skin, or your epidermis, via aquaporin-3.

Aquaporin-3 is a transporter that is essential for normal skin hydration, elasticity, and repair. Interestingly, mice lacking in AQP3 have dry and less elastic skin that can be fully corrected with glycerin.

This ingredient is non-irritating, plays well with almost every ingredient, and works across all skin types. Typical use is anywhere between 3-10% but can go up to 79% in some leave-on products.

Just know very high concentrations (>40%) can feel tacky in low humidity.

Glycerin is the name for this ingredient in American English. British English uses Glycerol/Glycerine.
