Product Review: Timeless Coenzyme Q10 Serum

I'm back today with a review of another product from Timeless Skincare - their Coenzyme Q10 Serum. From the name, you might think that it's simply a serum containing CoQ10, but it has a few other beneficial (and necessary IMO) ingredients for a good anti-aging skincare routine.

If you're not familiar with Coenzyme 10, you might recognize it as CoQ10 or ubiquinone. It is an antioxidant that when applied topically, may improve signs of aging. The Timeless Coenzyme Q10 Serum also contains Matrixyl 3000™, a polypeptide which helps maintain and restore collagen to fight wrinkles. Another beneficial ingredient is hyaluronic acid, which is capable of holding up to 1000 times it's weight in water. That means it brings a lot of moisture to the skin and can instantly improve the look of lines and wrinkles.


This product is packaged in a 1 oz. cobalt blue glass bottle with a dropper top. It has a pale yellow color with a serum consistency. It's thicker than the Timeless 20% Vitamin C + E + Ferulic Acid Serum, but it applies in much the same way. It glides easily over the skin, and while slightly tacky initially, it absorbs completely. I really like the way this feels on my skin!

I used this serum both in the morning and evening. In the morning, I used it after my vitamin C serum, and in the evening, I applied it 30 minutes after Differin or tretinoin (whichever one I was using). With my hands damp, I placed about 7-8 drops in the palm of on hand, gently rubbed my hands together to distribute the serum, then applied the serum to my face, neck, and decollete. Any remaining serum I rubbed onto the backs of my hands.


Ingredients: water, ubiquinone, aloe barbadensis, Matrixyl 3000™, glycerin, hyaluronic acid, vitamin E, benzylalcohol, dehydroacetic acid.

As with all Timeless products, this serum is paraben-free, cruelty-free, dye-free, fragrance-free, and made in the USA.

I quite liked this serum. I always appreciate a skincare product that is fragrance-free and absorbs completely. I never had an issue with applying my sunscreen and makeup or other skincare products. I didn't experience any irritation or breakouts. Again (I feel like I always say this!), I didn't see a change in my skin during the 2 months that I used the product, but I've been using Matrixyl 3000™ and hyaluronic acid products for several years, so I don't know that I would necessarily see a change. Does that make sense? (Update June 2018: I stopped using this for a few months, then started again. I do believe that my skin feels "plumper" and more hydrated when I use it. It's now a permanent part of my skincare routine!)

I used this twice daily for 2 months, and that emptied the bottle. Your mileage may vary depending upon how often and how much you use. The shelf life of the product is 2 years. Timeless occasionally has specials, one of them being 50% off, but you need to spend $75. (Update June 2018: I purchased my 1 ounce bottles on Amazon, but I purchased my 4 oz. refills from Timeless during one of their 50% off sales. They also have the 4 oz. refills on Amazon.)

This is definitely on my "repurchase" list. The only reason I didn't repurchase immediately is that I am testing the multi-peptide serum from The Ordinary which also contains hyaluronic acid (in the form of sodium hyaluronate) and Matrixyl 3000™, so there was no need for me to have two products with the same active ingredients.

(Update June 2018: My routine for using this product is now a little different. I'm only using it in the morning. No special reason for that, I just like to use some of my topicals in the morning and some in the evening. I felt like this one was better in the morning round-up.)
