What it is
Fullerene is a hollow, ball-shaped carbon molecule that can interact with free radicals, which is the basis for its use as an antioxidant in skincare. It is popular in Japanese and Korean formulas, including sunscreens, where it is added as a supporting antioxidant ingredient. Because the raw molecule is poorly soluble, it is usually supplied in stabilized water-dispersible or oil-dispersible forms.
Safety & warnings
Fullerene used in cosmetics is supplied in purified, stabilized grades and is generally well tolerated in finished products. As with any specialty ingredient, tolerability depends on the specific grade, carrier, and concentration in the formula.
Origin & sourcing
Synthetic; an engineered carbon allotrope produced industrially and then purified and formulated for cosmetic use, typically as a stabilized dispersion.
History
Fullerenes were first identified in 1985, a discovery later recognized with a Nobel Prize in Chemistry. Their use in cosmetics emerged later, becoming especially established in the Japanese market.
