This is the only Vitamin C serum I use, and I absolutely love it. I have natural skin with a few freckles, and my skin type is dry to normal — this serum works beautifully for me.
I use it only in the morning, right after my Zero Pore Pad, and I always follow up with sunscreen afterwards — that's an absolute must with any Vitamin C serum.
I've been buying it for years now, and I always keep a full-size spare bottle at home just in case. That alone says everything about how much I trust this product.
Highly recommend it to anyone looking for a reliable Vitamin C serum that actually delivers results over time.
