turmeric

Turmeric is a spice made from the dried, ground root of the Curcuma longa plant. It contains curcumin, a lipophilic, polyphenolic antioxidant pigment that gives turmeric its golden-yellow colour.

In addition to being a food seasoning, turmeric has numerous health benefits whether consumed orally vis foods and supplements or applied topically. Ongoing research has shown turmeric and the curcumin it contains play a safe and compelling role in promoting healthier, normalised skin.

On skin, in vivo research has shown that turmeric and its derivatives interrupt signaling in surface cells that trigger signs of irritation. Turmeric helps calm skin and may even play a role in reducing the look of acne-related redness by modulating pathways to restore a healthier, more even appearance.

Research has conclusively shown that turmeric is a potent antioxidant, largely due to its curcumin content (although turmeric also contains other antioxidants). Applying turmeric to skin can help offset signs of environmental damage and, to some extent, thwart the skin-damaging effects from UVB light.

As with many antioxidants, turmeric requires protection from air and light, as routine exposure causes it to break down and limits its availability to skin.

Beyond being an antioxidant, some research has shown the curcumin portion of turmeric boosts skin’s hyaluronic acid content, meaning turmeric can also be considered hydrating.
