FAQ
How often should I use this product?
Use morning and night right after cleansing, before toner and other serums.
Can I use this if I have sensitive skin?
Most people can use this comfortably, but if you have very sensitive or reactive skin, patch test on your inner arm 24-48 hours before applying to your face.
What shouldn't I mix this with?
This product doesn't have major known conflicts. As a general rule, avoid layering too many strong actives (retinol, high-% acids, vitamin C) in the same routine, and introduce anything new one at a time.

Skin feels smoother within 1-2 weeks, with firmer-looking skin after 4-6 weeks.
Is this product safe to use during pregnancy?
This product is generally considered safe for most routines, but as with any cosmetic product, consult your doctor if you're pregnant, breastfeeding, or have specific health concerns.
