Ingredient review
Hoya Lacunosa Flower Extract
INCI: Hoya Lacunosa Flower Extract
A gentle, antioxidant-rich flower extract with limited research but a good safety profile for most skin types.
In plain English
Hoya lacunosa flower extract is a plant-based ingredient made from the flowers of a tropical vine. It's added to skincare products mainly for its antioxidant content, which can help protect skin from environmental damage. Because it's a natural extract, it also brings a mild, pleasant scent and may offer some soothing benefits. However, there isn't a lot of scientific research specifically on this flower extract, so its effects are not as well-documented as more common ingredients like green tea or vitamin C.
