Smell: No noticeable smells.

Package: The package is similar to It's Skin ampoules with the glass-colored bottle and tube. The only major difference is that this serum needs to stay away from the sun. Hide it in your fridge or under your bed. Either or, try to keep it from being oxidized or the clearish liquid will turn yellow.

Application: The texture is watery, but it's a little thicker. Just be very careful if you have any cuts/open wounds because it will burn. The irritation isn't too bad since it goes away after at most 1min. Also, make sure to wear sunscreen if you're going to implement this into your routine. The ingredients in this serum will make your face more sensitive to the Sun and will likely pigment if there is lack of care. I'll also note if you're messy during application, you'll know since the lid's lips will get crusty.

Summary: This stuff is great. Better than It's Skin VC Effector for sure - just be wary of the initial burning sensation since it's pure VitC, not a derivative of it.
