What it is
An essential oil extracted from the needles and small branches of Pinus cembra, also known as Swiss stone pine or Arolla pine. It is rich in aromatic compounds like monoterpenes and is used primarily for its fragrance.
How it works
In a cosmetic product, this oil provides a natural pine scent and may contribute to a feeling of freshness. Some of its compounds have been studied for antioxidant or anti-inflammatory activity, but in typical skincare formulas, its main job is to add fragrance and a sensory experience.
Pros

Contains compounds like monoterpenes that have shown antioxidant effects in lab studies, which may help protect skin from environmental stress.
Cons and cautions
