Formula IngredientChelating Agent

Phytic Acid

INCI: Phytic Acid

Phytic acid is a naturally occurring plant-derived compound (inositol hexaphosphate) found in seeds, grains, and legumes. Despite its name, it does not function as a chemical exfoliant; instead it acts primarily as a chelating agent, binding to metal ions (such as iron, copper, and calcium) that enter formulations via water, thereby stabilising products and preventing oxidative degradation. It also has antioxidant and mild skin-brightening properties, including documented depigmenting activity relevant to hyperpigmentation and melasma.

Is Phytic Acid safe? Key considerations

Can Phytic Acid cause irritation?

Low Risk

Phytic acid is generally well tolerated at cosmetic concentrations. It is not a true acid exfoliant, so it does not carry the same stinging or barrier-disruption risk as AHAs or BHAs. No Annex II or III restrictions in EU CosIng. Sensitive skin types may experience mild irritation at higher concentrations.

Does Phytic Acid increase sun sensitivity?

No Risk

Phytic acid does not increase photosensitivity. It is not an exfoliant and does not accelerate cell turnover in the manner of AHAs or retinoids. No special sun protection is required based solely on its presence in a formulation, although broad-spectrum SPF is always recommended as general skincare practice.

Is Phytic Acid safe during pregnancy?

Safe

MANUAL REVIEW: No specific clinical safety data for topical phytic acid during pregnancy was identified in available sources. Based on its plant-derived, non-exfoliating nature and low absorption profile, it is generally considered low risk. Consult a healthcare provider if in doubt.
