Plantamajoside is used in cosmetic and skincare formulations for its antioxidant and anti-inflammatory properties. It helps protect the skin from oxidative stress caused by environmental factors like UV radiation and pollution. Due to its ability to inhibit inflammatory pathways, it is included in products designed to soothe irritated or sensitive skin. It also supports anti-aging treatments by reducing the appearance of fine lines and improving skin elasticity. Additionally, plantamajoside is being studied for its potential neuroprotective effects, suggesting possible use in topical or systemic applications targeting neurodegenerative conditions.
