After using this serum every other night, it does make a visible difference in firmer-looking skin. I'm glad I tried this and will re-purchase when the bottle is finished. It's also very economical. I use about 3 drops for my face & neck and possibly a 4th drop for my chest. The bottle will last a long while at this rate. (On the other night, I use the Timeless CoQ10 serum. I decided to not to use both serums on the same night, as possibly too much for my skin.)

I have been using Matrixyl for the past 7 years. It has made a huge difference in my 57 year old skin!

Mytrixyl Synthe 6 is the best product for my aging, dull, dry skin. Together with Vitamin C it makes my skin plump and glowy. I would purchase it again.

Lovely hydrating serum layers well.

Thank you Timeless for caring about my skin!
