The natural scent of Hypochlorous Acid is often described as reminiscent of a pool or spa. This is because HOCI has a similar chemical structure to the chlorine used in pool water disinfection. However, unlike harsh chlorine-based cleaners, the smell of HOCI is much more subtle and faint. It dissipates quickly after application and does not linger on the skin or in the air. SkinSmart does not contain any added fragrances, so you're simply experiencing the natural aroma of this innovative, nature-derived ingredient.
