HALOCIDIN SUBUNIT A AMIDE/HALOCIDIN SUBUNIT B AMIDE
Safety score · 0–100
Moderate
Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.
A highly bioactive antimicrobial peptide, which is more of an experimental biotech active than a comfortingly bland cosmetic ingredient.
Halocidin-derived peptides are designed around strong antimicrobial activity, so they are not chemically quiet the way simple humectants are. That kind of biological potency raises more questions about microbiome disruption, irritation, and limited long-term cosmetic safety data.
Function
Skin benefits
- May help protect formulas or skin from microbial stress
- Provides skin-conditioning activity
Known concerns
