Computed with the same four public criteria as every profile. The human-evidence grade on an indexed profile is set automatically and may change when it is hand-reviewed. It is not a safety score, not a purity rating, and not medical advice, and not a claim that this compound treats, cures, or prevents any condition.

What it is

Soybean peptide refers to short protein fragments derived from soy, used mainly as an ingredient in cosmetic and skin care products. The listed database formula corresponds to a specific small peptide, though the name is also used broadly for mixtures of soy protein hydrolysates, so the exact composition can vary by product. Soy peptides are thought to act as skin conditioning agents and have been studied in the lab for antioxidant and moisture-related effects.

What the evidence shows

Automatic summaryLimited human data

There are about 161 published papers and 2 registered human trials, with no clear advanced-phase clinical testing, so the human evidence for any specific effect remains limited and not conclusive. It is not FDA-approved for any medical use and is regulated as a cosmetic ingredient.
