I’ve tried so many vitamin C serums (especially ascorbic acid, and this one from TIRTIR is by far my favorite. First off, I love that the formula isn’t watery—I can drip it directly on my face without it sliding off instantly. It has a smooth, slightly thick texture and a beautiful shiny finish that feels great on the skin.
What really stood out to me is the lack of that harsh, metallic vitamin C smell you get from other serums. This one has either no scent or a very faint, pleasant one, which I really appreciate. The serum comes with the pump separate in the box, which I thought was a nice touch—probably to help with stability. And honestly, the pump is perfect—no mess, no waste.
At 24% pure vitamin C, it’s rare to find something this potent that also includes great additions like collagen and calming ingredients—and I’ve had zero irritation or side effects. It’s amazing for my skin or for anyone who’s looking into effective serums. I also keep it in the fridge, and I love that this serum is formulated with tech that extends its shelf life and resists oxidation. The fact that it stays fresh longer really makes a difference.
On top of all that, TIRTIR is a clean brand I trust—and I appreciate how they manage to keep it so affordable without cutting corners. Highly recommend this for anyone looking for a high-quality, powerful vitamin C serum that’s actually enjoyable to use.

I use this 2 to 3x per week during the daytime and have noticed a visible change in my complexion, including a more even complexion, and a reduction in the size of some of my dark spots. Its very hydrating, and slightly oily, but that doesn't bother me much. There is no tackiness that I've experienced in other serums with this high of a vitamin C concentration.
