What it is
DNA used in cosmetics is a high-molecular-weight nucleic acid most often obtained from fish sources such as salmon milt. In skincare and sun care it acts as a skin-conditioning agent that can help form a light film on the skin surface and support a smooth, moisturized feel. It appears in some Korean sun and anti-aging products as a marquee conditioning ingredient.
Safety & warnings
Cosmetic DNA preparations are generally well tolerated for topical use. Because it is frequently sourced from fish, individuals with fish or seafood allergies may wish to take note, although topical exposure differs from ingestion. It is not associated with significant irritation in normal use.
Origin & sourcing
Natural in origin. The DNA used in cosmetics is generally extracted from natural biological sources, commonly fish such as salmon.
