It's still too early to say if it does a good job, but what I will say is that it is very thick and takes a long time to absorb, and this is a problem when you do 6 steps for your morning routine and are in a hurry to put on makeup. I use 6 drops as the instructions say, but even then it seems like a lot of product. One thing is certain, the bottle will last a long time. I have also bought the Medik8 night restorative cream and it is amazing. I hope this serum is too.

I don't have much experience with vitamin C. This was the first one I tried after careful research due to sensitive skin with mild rosacea and spider veins (age 45+). I have been using it for 2-3 months and I am absolutely satisfied. It has a light oil texture, pleasant scent, spreads easily, is also absorbed quickly and has not irritated my skin at all. I will buy it again.

Contains Tetrahexyldecyl Ascorbate (THDA). THDA is one of the two best Vitamin C derivatives, it is extremely stable, does not irritate, and is absorbed deeply. It is much better than inferior derivatives such as Ascorbyl Glucoside, which is one of the "worst" Vitamin C derivatives. Although the gold standard (L-Ascorbic Acid) is more potent, THDA offers almost the same action without the risk of oxidation and irritation.

The best vitamin C serum I have ever used!!!!!
The first vitamin C serum that also hydrates my skin.

Nice product, but it has an oily texture, like oil, and takes about half an hour to absorb with the dosage indicated. I think I liked the pure c15 more, my skin looked more radiant.
