I started using the Timeless Coenzyme Q10 Serum because I used to use (and love) Timeless’ 20% Vitamin C+ E serum. I no longer use their Vitamin C serum (now I spend $$$$ to use Skinceuticals CE Ferulic) but I am still using their CoQ10 serum.

Mia’s review: 

Similar to their 20% Vitamin C+E serum, I have not experience any irritation or break outs but was concerned about

the benzylalcohol drying out my skin. I haven’t noticed that it dries out my skin.I have used at least four of the 1 ounce sized bottles and am now committed enough to the serum that I just purchased the 4oz refill size.

I honestly use the Timeless Coenzyme Q10 serum simply because I haven’t found any other Q10 serum that doesn’t include ingredients that I don’t use on my face like silicones, caprylic/capric triglyceride, or essential oils. because it has a large % of active ingredients and a great price. I will always use a CoQ10 serum because of this research paper that shows topically applying it topically to skin has some benefits. The only issue is that the amount they used in the experiment was in micrometers and I don’t know how (or if) that translates to % of ingredients. Also, the paper was written by current/former employees of Beiersdorf AG whose brands include La Prairie, Nivea, and Eucerin. To me, that means the results of the study may or may not be true because they may be using the study results for marketing purposes.

The serum also includes Matrixyl 3000 and hyaluronic acid, both of which I don’t mind having in my skincare routine. So to me, those are both additional reasons why I don’t plan on quitting this serum at anytime.

I recently started using DHC’s CoQ10 face cream on my neck, thinking that it can’t hurt to use CoQ10 on my neck, too.

Updated January 2025: I love this serum so much! I’ve used it twice a day for at least 5 years now. I believe the company says it has 2% coenzyme Q10 and 8% matrixyl 3000. To me, that is a lot of actives for the price. And I think very few companies state how much active ingredients are in their products because it is usually a tiny amount (i.e., often those ingredients are at the end of the ingredients list and listed after the preservative). Just be sure to shake this when you first get it to make sure it is mixed and then occasionally shake it because it separates. If it looks clearish in the dropper, you should shake it.
