Benefits of Wintergreen Oil
Natural Astringent: Wintergreen oil’s astringent properties make it an excellent choice for toners and cleansers. It helps tighten and refine skin pores, leading to a smoother and clearer complexion.
Soothing Sensation: The cooling effect of wintergreen oil can soothe irritated skin, making it a preferred ingredient in after-sun products and creams for inflamed skin.
Muscle Relaxation: In massage oils and balms, wintergreen oil is known to relax and ease muscular tension, offering a refreshing relief. Wintergreen Oil is a natural source of Methyl Salicylate, an organic compound that makes pain sensors in the skin less sensitive to pain. It also widens the blood vessels in the skin. Together, these two properties help control muscle pain while stimulating blood flow to the region.
Potential Antibacterial Properties: The inherent antibacterial qualities can help maintaining clear skin and reducing the occurrence of breakouts. The antibacterial action of Wintergreen Oil is attributed to certain compounds present in its composition, which have been shown to be effective against a wide range of harmful bacteria.
Invigorating Aroma: Beyond its benefits for the skin, the minty and uplifting aroma of wintergreen oil can enhance mood and stimulate the senses, making it a popular choice in aromatherapy-based cosmetics.
