Step 1: Shake the bottle vigorously before every use to evenly distribute the Bacillus spores throughout the formula.

Step 2: After cleansing and toning, apply 1–3 drops to dry or slightly damp skin.

Step 3: Gently pat the serum into your face, avoiding the immediate eye area.

Step 4: Follow with any additional hydrating serums and your favorite moisturizer. Finish with SPF during your morning routine.

Frequency: Use once daily.

Good To Know: Natural settling and small white or beige particles are normal! These are part of the spore-based formula. Shake thoroughly before each application.

Important: If using a leave-on benzoyl peroxide treatment, use it in the opposite routine from SIV unless your skincare provider advises otherwise.

Patch test first if your skin is highly sensitive. Discontinue use if irritation occurs.
