I don't use it for heat protection at all.
CVS is NOT authorized to sell it, could be old, counterfeit/fake, improperly stored/ineffective, etc. . .
I'd buy it online, they send samples if you do
Thank you Swanky, for the clarification!! If they are fake or counterfeit, I would not know since I do not buy them there.
It is great to know what to look for, though!!!
I am very lucky since the distribution center for Latin America is in my hometown so when I go there, I stock up!
