For external use only. Avoid the eye area. Do not use if allergic to any ingredient. If your skin is very sensitive, patch test on a small area first. Stop use if irritation occurs. If you use a leave-on benzoyl peroxide, apply it at the opposite time of day to SIV. If pregnant, check with your healthcare provider before starting new skincare. Store at room temperature away from sunlight.

Why do I have to shake it?

The Bacillus spores settle at the bottom. Shaking spreads them evenly so every drop works the same.

Can I use it with benzoyl peroxide?

SIV suggests using leave-on benzoyl peroxide at the opposite time of day.
