What the gurus are saying

This peptide serum earns consistent praise for delivering hydration alongside visible firming and help with fine lines and wrinkles. Gurus note it pairs well with tretinoin or retinol at night and works gently enough for twice-daily use, making it a good option for anyone starting to see accelerated signs of aging or looking for a peptide serum that won't irritate. It sits in the mid-price range and may be less readily available than some alternatives, but those seeking hydration plus peptide support without investing in copper peptides find it worth the hunt.

"Timeless makes a stronger one than this, and it's called Timeless Skincare Matrixyl Synthe'6 Serum."
Approved
"The Timeless Matrixyl Synthe'6 Serum is hydration with added peptides from the matrixyl complex, which I enjoy. I have other serums I use for my peptide fix, so I like this for hydration with some peptides extra. It isn't as easy for me to get as other ones and it's in the medium price range, but the Timeless range is quite nice if you want a hydration plus peptide serum and don't want to invest in copper peptides."

"I follow up with a second serum, the Timeless Matrixyl Synthe'6 Serum. The added peptides obviously won't hurt, but it is the hydration I am mainly after."

"Synthe'6 is another peptide from the Matrixyl complex, the name kind of gives it away, it's supposed to synthesize six important parts of the skin structure like collagen, elastin, and other things. Again it's Matrixyl but not the same as Matrixyl 3000, and it's a hyaluronic acid serum with some extras, perfect for those like myself who are on the more mature side and want to add hydration but with a bonus."

"I apply my Timeless Matrixyl Synthe'6 Serum, this is a peptide serum. The matrixyls help with varying signs of aging so they'll help with wrinkles, they'll help with discoloration, so help with all kinds of things. They're very hydrating."

"The Timeless Matrixyl Synthe'6 Serum is a nice clear runny liquid. I just put on about a half a dropper of this, rub it along, rub it all over my face and all over my neck. Matrixyl Synthe'6 is another peptide that hits six different signs of aging and it helps your skin to produce more collagen and helps to reduce your wrinkles."

"The second thing that I put on after that at night is my Timeless Matrixyl Synthe'6 Serum. This is another matrixyl but this one helps with six different signs of aging. This one is supposed to help with synthesis of collagens types 1, 3, 4, fibronectin, lamins, and hyaluronic acid. So this is another great peptide that has been shown to work in the skin. Very lightweight, fluid serum that's easy to apply."

"This Matrixel Sin 6 serum contains 2% Matrixel Sin 6. And this one is also kind of a double duty product because you do get the CoQ10 in there."
Approved
"This is a peptide serum that addresses fine lines and wrinkles and to help firm the skin. This is also very hydrating as well and it could be paired with retinol with tretinoin you can pair this up with a lot of things. I really like this one more so over the Timeless Matrixyl 3000. Matrixyl 3000 is very similar to this, it's peptides, but Matrixyl 3000 is more for those that are starting to see early signs of aging or maybe you haven't seen it yet but you want to prevent it. The Matrixyl 3000 would be the serum that I would go with if you're starting to experience more accelerated signs of aging, loss of firmness, fine lines, then I would say go with Matrixyl Synthe'6. I think it works a lot better from my experience with it. I do have a backup so I will be continuing with this for sure."

"Matrixyl Synthe'6 is more for accelerated signs of aging. If you're starting to develop fine lines and wrinkles, I would say go with Synthe'6, and this one from Timeless is exceptional. It's super hydrating, it never pills with other skincare products. You can use this paired up with your retinol at night time or tretinoin, or you can also use this in the morning if you wish, up to twice a day. Once a day is honestly sufficient enough, but if you want to use this twice a day, go for it. It's a peptide, it's not going to be irritating on the skin, at least for most people. It's a great product to use to firm the skin. It can also help to stimulate new collagen as well. If you're starting to see signs of aging, that sagging of the skin, go with the Matrixyl Synthe'6 because I truly believe that you will see better results with this one."

"I really like the Timeless Matrixyl Synthe'6 Serum. This is a great peptide serum to incorporate before your tretinoin or of course before your retinal because peptides really help to firm the skin and they can really give more of that youthful look to the skin with consistent use. I love pairing up peptides with tretinoin and I just think that is one of the best pairings you can do for signs of aging and to firm up the skin."

"I love the Matrixyl Synthe'6 since it's definitely underrated and I think you should try this at least once. You can use this prior to tretinoin or retinol, or you can just use this on its own and use this every day twice a day if you wish to. This is also another great alternative option if you're someone that can't use vitamin C or retinol, this would be like the next best thing to use to target signs of aging."
