Are Hypochlorous Acid (HOCl) Sprays Safe During Pregnancy?
Hypochlorous acid (HOCl) is a gentle antimicrobial used in dermatology to calm redness, support wound care, and reduce breakout-causing bacteria. Topical HOCl mists are generally low risk in pregnancy because they act on the skin surface and are non-sensitising. They shine as a calming step between cleansing and moisturising, especially for reactive or acne-prone skin.
