Thank you yes you are right it would be difficult to promote 2 in 1 product. But I just thought if you are suffering from acne both would be great for skin and more time efficient. Also not sure why Vitamin c is just few drops being advertised, as acorbic acid oxidises so quickly you should use it as quickly as possible. I am using at home and it is not a big issue to put more actually i think my skin looks better from bigger quantity. Thank you both for your help.
