Safety

Enzyme preparations belong to protein, which may induce sensitization and cause anaphylaxis in sensitized individuals. Long-term exposure may cause minor irritation for skin, eyes or nasal mucosa, so any direct contact with human body should be avoided. If irritation or allergic response for skin or eyes develops, consult a doctor.
