I use this twice a day as a toner. I've read that your body slowly stops producing Coq10 at the age of twenty, so by that logic I would imagine the older you are the more effective this product might be. I love using it, it's moisturizing to the point that I sometimes don't need to even use a moisturizer.

This toner is one of my favorites and not only is it a great toner ! It is also one of the best packaging I’ve ever had ! It’s so good ! I love this product line ! 

This toner was really great snd it’s worth it to mention that bottle itself is amazing - excellent packaging ! 

Not only is this a great toner , but I’d also like to mention that the packaging is really excellent! It’s in a beautiful purple bottle that is just really good packaging . I love this toner though bc it really makes my skin feel clean and refreshed ! 

This toner is really great! I would definitely recommend it and I’ve been using all types and kinds of toners for a whole now , and this one leaves my skin feeling refreshed and no residue ! 

I really really love this toner - I’ve been obsessed with toners lately , and this toner is definitely my top 5 that I will keep going back to in the future ! 

I recently learned about the benefits of CoQ10 and how our bodies slowly stop creating it once were twenty years old. I've gone through one and am on my second bottle now. Though I am young and not old enough to have noticeable wrinkles, my skin feels more bouncy and firm. Would recommend to anyone, I use it in combination with a peptide serum.

Love this, does not strip my skin or leave it feeling dry. Does not cause my skin to have any bad reaction. Will keep purchasing!

I cannot believe this product isn't as talked-about on Asian Beauty sites... I know this is Japanese rather than Korean, but it's great AND it has CoQ10! This is hydrating and calming, and really helps my non-DHC moisturizer absorb better. I put this DHC lotion on, and immediately follow up with moisturizer, to lock in the hydration immediately as well as to give the moisturizer a damp base to sink into. Since it has CoQ10, I feel that it's more beneficial to use this as a toner, compared to using a random toner with the fad-ingredient-of-the-quarter. I wish it came in a spray bottle, though. The droplet-dispensing function doesn't help me control how much to use each time.

I use this twice a day and it does it's job. It leaves my skin feeling balanced and hydrated
