    Really wanted to like it

    Not seeing a big reduction in oil production on my nose compared with Inkey's regular Niacinamide, esp for almost twice the price. Am also seeing a white cast too on my fair skin with grittiness when it dries- am needing to shake the squeeze tube very well before applying but some days the cast is evident when dry.

    Hello Emi,

    Thank you for taking the time to share your feedback about our Excess Oil Solution. We're truly sorry to hear that you haven't noticed a significant improvement in oil reduction compared to our original Niacinamide formula, and we understand your concerns about the value, especially given the price difference. We're also disappointed to hear about the white cast and texture issues you're experiencing. While shaking the product thoroughly before use can help with consistency, we understand this hasn't fully resolved the grittiness you're noticing. We would be grateful if you could reach out to our askINKEY Team who can support you further with your experience and help identify a more suitable solution for your oil control needs 🖤

    White Cast on Darker Skin

    It seems to do an okay job at controlling oil. However even when used as directed (under other products) it often leaves a white streaks on my skin. These tend to take a while to show up. So even if I look okay in the mirror 30 minutes later I look like an inverse racoon.
