okay
I've been using the Vit. C serum and retinol every day. I've been taking the collagen as much as I can tolerate (I hate the taste it imparts). I see absolutely no difference in my skin.

Hi Erica, We appreciate your feedback and are sorry to hear that you have not yet noticed visible improvements. The Vitamin C serum, retinol, and collagen are designed to support skin health, but visible changes typically require consistent use over several months rather than just weeks. Some users may also experience taste sensitivity with collagen, and we understand how that can make daily use difficult. Our medical experts are available to review your case and provide tailored guidance on how to maximize your results and adjust your routine if needed. Please reach out directly to [email protected] so we can assist you further.
