Well to be specific about the Tiam Red VIT C serum, despite the tight seal a large drop of the serum had come out of the bottle onto the inside of the box which had oxidized. So I was like oh boy! When I opened the bottle, it was same as though I was opening a cola or any aerated and shaken bottle seal with the same sound. But turns out the product was entirely fine, it was just the drop that I attribute to packing fault. There was an additional dropper which fits the bottle and seals it tighter than it’s cap itself.

The serum is red but is good, spreads well, absorbs and effective. Although note that it is more serumy than any other VIT C I have tried. It can feel a tad bit tacky but it gets absorbed for sure and there are visible results. This is the other weird smelling product that I spoke about. Some say it’s the tuna smell and some say it’s the indian food poha smell. Whichever it is, it stays only until application and goes away immediately after.

I would give it a bonus for after being 20% concentrated it did not irritate me at all like some others have. It has got to be the good formulation and stability as well I guess. My guess will be the B12 and Glutathione it has in it help with the no-irritation part. This can also be blended with other brightening products with no irritation. I have seen some visible results in about 10 days.
