Caffeine is a topical active used in skincare for its antioxidant properties and ability to constrict blood vessels, which may temporarily reduce puffiness and the appearance of under-eye darkness. It is also studied for reducing localized fluid retention and protecting against UV-induced oxidative stress.
Niacinamide (vitamin B3) is a water-soluble active that supports the skin barrier, regulates sebum, brightens hyperpigmentation, and reduces inflammation. It is widely tolerated across skin types and used in concentrations commonly ranging from 2% to 10%.
Acetyl Tetrapeptide-5 is a synthetic peptide used in cosmetics primarily to reduce periorbital puffiness and improve skin elasticity by inhibiting angiotensin-converting enzyme activity and reducing fluid accumulation and glycation. It is commonly found in eye creams and anti-aging formulations.
Bidens Pilosa Extract is a plant-derived ingredient rich in polyphenols, flavonoids, and phytic compounds, used in skincare for antioxidant, anti-inflammatory, and retinol-like skin-conditioning effects. It is sometimes marketed as a gentler botanical alternative to retinoids for improving skin texture and tone.
