And it is here that we see the growing success of peptides in cosmetics and the importance of their dual role, both as messengers and as diligent allies in the health and youthfulness of our skin.

In fact, when it comes into contact with a fragment of collagen such as Tripeptide-1 or GHK, the skin may think that a collagen depletion process is taking place and therefore tells the body to take action to reproduce again. 

And the consequence of all this is younger-looking skin and a completely regenerated epidermis.

Le Opinioni su Mary & May 6 Peptide Complex Serum Le recensioni sul siero viso coreano ai peptidi di Mary & May.


Skin: Mixed

Excellent serum

I have purchased other products from this brand before and have always been very happy with them. The serum is super light and moisturizes without being sticky. And then the ingredients are all natural and certified.  Great!


Skin: Normal

What a pleasant surprise.

I was looking for an anti-aging serum to help improve my skin. I had heard a lot about peptides and copper, but mostly how not to combine them. I decided to try it and it seems to help retain moisture in my skin. I also apply it to my eyelids in hopes that it will help improve elasticity. It’s been a couple of weeks, so I can’t say I’ve seen a miracle, but my eyes look more rested and my eyelids less droopy. So far so good!


Skin: Dry

Moisturizes and does not dry

This peptide serum from Mary & May is a really good product! After application, I feel my skin pull slightly but I don’t feel a dry feeling. The only downside for me is that my skin literally drinks it up. This serum penetrates the skin too fast, so I have to use more than other serums.




I love the ingredients in Mary & May’s peptide serum. The serum has a light consistency and penetrates quickly and perfectly into the skin. For this reason, I use it during the day because it does not cause any oiliness. I have acne prone skin and with this serum, I have not had any problem with rashes!


Skin: Sensitive

More definition, firmness and hydration for my skin.

I’ve been using this serum daily for two weeks now and I can confidently say that although I’ve only done a few applications yet, I can feel my sensitive skin smoother, tighter and definitely more hydrated.



It goes well with my skin: I can’t recommend it enough!

I love the packaging, especially the sensitivity of the pipette. It’s so easy to use to dose the serums and you can be sure to apply the right amount of product to your skin.


Skin: Dry/Sensitive

Never Again Without Peptides

This serum is formulated with 6 types of peptides for a synergistic effect: carperpeptide, hexapeptide and trapeptide promote skin regeneration, while palmitoyl tripeptide and palmitoyl pentapeptide have excellent effects on wrinkle reduction. The six peptides are combined in a golden ratio designed to regenerate collagen and skin elasticity.

This is a clear, unscented serum with a viscous but weightless texture upon application and a watery consistency that absorbs almost instantly and is the lightest of the peptide serums I’ve tried so far.

I’ve been using this serum in my nighttime routine along with other active ingredients (including retinoids) and I have to say this one layers really well, considering my wide range of layers. The increase in elasticity can be felt immediately after application.

It’s been a stressful couple of months for me, with a lot of tension at work compounded with holiday stress, but this serum has done wonders to not let any of that “drama” seep out of my face. 🤪

Thanks to this product, I’ve come to the conclusion that a peptide serum needs to be a staple in my routine. Sure, I like to vary brands, but this will definitely have a spot in my personal “Heavy Rotation”


Skin: Oily

The Hydration Boom

This serum is what I call a hydration blast! It has an interesting gel-like consistency that turns into a watery serum upon contact with the skin, the feeling of which is that you just splashed your face with water! 

Unscented. It absorbs immediately without leaving any residue or generating stickiness. Already after the first applications my skin was plumped and hydrated. Another bonus point for the price, really low for what it offers.
