Can I use this if I have sensitive skin?

This formulation is quite potent with 15% vitamin C, so those with sensitive skin should start slowly. Begin with every other day application and gradually increase. Consider our SkinIQ analysis to determine if a lower concentration might be better suited for your skin.

Why does the serum sometimes look darker or yellow?

Vitamin C serums naturally oxidize when exposed to light and air, causing color changes from clear to yellow or brown. While slight yellowing is normal, significant darkening indicates the product has lost potency and should be replaced.

Can I layer this with retinol?

Use vitamin C in the morning and retinol at night to avoid potential irritation. If you want to use both in your AM routine, apply the vitamin C first, wait 10-15 minutes, then follow with retinol - though this is typically unnecessary.

How long before I see results?

Most patients notice improved brightness and radiance within 2-4 weeks of consistent use. Significant improvements in dark spots and fine lines typically become apparent after 6-12 weeks of daily application combined with proper sun protection.
