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.

What it is

An extract derived from the flowers of Hoya lacunosa, a species of flowering plant in the Apocynaceae family, native to Southeast Asia.

How it works

The extract contains natural compounds like flavonoids and phenolic acids that act as antioxidants, neutralizing free radicals that can cause premature aging. It may also have mild anti-inflammatory properties, helping to calm irritated skin.

Limited research

There are very few peer-reviewed studies specifically on Hoya lacunosa flower extract for skincare, so its benefits are not as proven as more established ingredients.

  • Those with normal to dry skin who enjoy botanical ingredients

Use caution if
