Pinus Densiflora Leaf Extract
Explained
This ingredient comes from the needles of the pine tree native to Korea and Japan. It's rich in antioxidant compounds like protocatechuic acid and shikimic acid.
Research on human skin fibroblast cells found that the extract inhibited UVB-induced cytotoxicity and suppressed the enzymes that break down collagen and reduce skin elasticity. This extract also inhibited elastase activity which is relevant for maintaining skin firmness over time.
Studies also show that it has antifungal activity against Malassezia furfur. This is the yeast that causes conditions like dandruff, seborrheic dermatitis, and folliculitis (fungal acne). It also displays anti-inflammatory activity.
On top of all this, all tested fractions of the extract demonstrated significant tyrosinase inhibitory activity comparable to ascorbic acid. This suggests it can play a potential role in fading hyperpigmentation.
