There is nothing suitable or inappropriate, just use it if you like!! The real effect of cosmetics is moisturizing and hydrating! And the real full name of Q10 is coenzyme Q10, which is a nutritional medicine and is now available in the market. There are some additives in cosmetics, but there are still very few that are actually added, because it is difficult to determine the actual application effect. It is all a concept and publicity technique. Like you said, this is just the name of a brand!!
