- Cleanse
Start with a gentle, microbiome-safe cleanser to prep your skin. - Tone (Optional)
If you use a toner, apply it after cleansing and before SIV. - Apply SIV
Shake the bottle well to activate the Bacillus spores. Dispense 1–2 pumps and gently apply to your face, concentrating on areas of imbalance, redness, or irritation. - Wait
Allow the serum to absorb for 5–10 minutes before applying other products. - Continue Your Routine
Follow with your regular skincare—serums, moisturizer, and SPF (if used in the morning).
Tips & Important Notes
- Shake Well
This ensures the Bacillus spores are evenly distributed throughout the formula. - Apply to Damp Skin
Helps improve absorption and effectiveness. - Be Patient
Waiting a few minutes before layering additional products gives the serum time to activate on your skin. - For Sensitive Skin
Apply SIV before other serums to help build tolerance. - After Treatments
Avoid using SIV for 24 hours after microneedling or invasive procedures. - Complementary, Not Curative
SIV enhances your skincare routine but is not a replacement for prescribed treatments or medical skincare products. - Morning or Night
SIV is safe and effective for use in both AM and PM routines.
