What is Phytic Acid?
Phytic Acid is a natural compound found in the seeds and fibre of plants such as grains, legumes and rice bran. It is how plants store phosphorus. In food, it is known for reducing how well the body absorbs minerals like iron and zinc.
In skincare, phytic acid is used as an antioxidant, a mild exfoliant and a soothing ingredient. It is gentle compared with most exfoliating acids and is often added to formulas that aim to even out skin tone.

How Does It Work?
Phytic acid has a few jobs. As an antioxidant, it helps neutralise free radicals, the unstable molecules that stress skin cells. It also has a calming reputation, which is why it is often added to antioxidant-focused formulas.
It is also a mild exfoliant. At around 2 to 4 percent, it is often combined with glycolic or salicylic acid, and it appears in some professional peels aimed at uneven pigmentation. The exfoliating effect of phytic acid is based on newer research than the antioxidant and soothing effects.
A 2021 clinical study in the Journal of Cosmetic Dermatology tested a facial emulsion with 10 percent glycolic acid, 2 percent phytic acid and a soothing complex for 12 weeks and reported improvements in hyperpigmentation, texture and tone with good tolerance. Because the product combined several actives, the results cannot be credited to phytic acid alone.
