Hyaluronic Acid, Collagen, and Peptides Oh My!

13 Mar

Hyaluronic acid, collagen, peptide….these are all terms and ingredients that are prevalent in today’s beauty industry jargon.

But what are these ingredients, how do they aid in skincare and who should use them? If you aren’t proficient in chemistry (like me!), trying to find that answers to these questions can be a bit daunting. Glycosaminoglycan… huh? Oligomers… what? Have no fear – Peach & Lily is here! I will try to answer these questions (and more!) in the most basic terms.



In general, all three compounds are all naturally formed in the human body and play an important role in keeping our skin looking youthful and healthy.


Collagen is a protein that your body produces to support the skin’s structure and keep it firm and elastic. Since collagen production decreases fairly rapidly as we age, our skin ultimately starts to sag (read: less collagen = less structure = more wrinkles)


Hyaluronic acid (HA) is described as “nature’s moisturizer” because its main function in the body is to bind with water. 50% of the body’s HA is found in the skin tissue, so it is a vital ingredient in keeping skin healthy!

Young skin is smooth and highly elastic because it contains a high concentration of both collagen and HA.  The HA acts as a space filler by binding to water and helps keep the collagen moist and elastic (read: more moisture = healthy, plump skin). Unfortunately, as we get older, the body isn’t able to maintain this same level of concentration, which results in the skin becoming drier and prone to wrinkles.


Peptides are an entirely different beast. They are short chains of amino acids that are formed when collagen and skin tissue break down.  The peptides essentially signal to cells that skin has been damaged and that it needs to produce more collagen to heal it (read: more peptides = cells produce more collagen & HA = healthy, young skin).


Obviously, all three compounds are very important in our skin care regimen. I firmly believe that you are never too young or too old to protect and care for your skin.

20’s and 30’s – We recommend investing in some form of Hyaluronic Acid and/or collagen boosters

Mature skin (late 30’s onwards) – Make sure that peptide is a major ingredient in your skin care products

Peach and Lily carries highly-concentrated HA, collagen, and peptide serums from Mizon. Note – Mizon doesn’t put just a little bit of the ingredient in there like most beauty brands, they put in A LOT. The collagen serum has 90% marine collagen. The HA serum has a 50% HA concentration, and the peptide has a 45% peptide concentration. Major ingredients = major results.

    Thanks for this info! I’ve been intrigued by all these ingredients for a while now and have even tried hyaluronic acid too. My question is though, how does oily skin play into all this? I am always afraid that these ingredients will make my skin oilier.

      Hi Lynda! How did the hyaluronic acid work out for you? Usually, it doesn’t make your skin oilier and is, in fact, a great option as far as moisturizers go for oily skin types. The collagen and peptide serums are also noncomedogenic so they shouldn’t make you oilier. In general, are you oily year round or more in the warmer weathers? And is this more in your t-zone or all over? And is your skin sensitive? Knowing a bit more about your skin type would be helpful, but as far as these ingredients as it relates specifically to oiliness, these shouldn’t make you oilier. I hope this is helpful and always feel free to leave comments or questions!

        aww thanks for your reply! I’m oily year round (it seems) but I guess more so in the warmer weathers. More in the t-zone. In the winter, there has been times when my skin is both oily and flaky (dry) so it’s been fickle and hard to find a suitable moisturizer. I’m also entering my thirties (sad) so I’m also looking for a multitasking regimen (anti-acne, anti-oily, anti-aging, anti-pores, etc). I will definitely give hyaluronic acid and/or collagen another try. And any advice/suggestions would be great!! 😉

    I needed to create you one tiny word to be able to thank you so much the moment again with the breathtaking methods you have featured on this site. It was surprisingly generous with people like you to offer publicly exactly what many people would’ve sold for an electronic book in order to make some bucks on their own, principally since you might well have done it in the event you considered necessary. The suggestions as well worked as a fantastic way to understand that someone else have the same desire like my very own to learn very much more regarding this matter. I am sure there are many more pleasurable occasions in the future for people who scan your website.

    I’ve recently added the peptide serum as part of my daily skincare routine after reading your article. As a side note, I alternate usage of other serums such as vitamin E and vitamin C. I have a few questions… is it ok to mix in the peptide with the other serum and apply it to face or is it better to apply one after another, or would it be an “overkill” (too many serums at the same time)? Secondly, do you recommend alternating serums as a day/night routine or should I just stick to one serum?

    • Peach & Lily May 7, 2013 at 6:01 pm #

      Hi Eileen – It’s OK to mix the serums altogether. It’s also totally OK to use them one after another. It just depends on your preference for the consistency of the serums when you mix it altogether. Also, it wouldn’t be “overkill” to use all of these together. 3 different key ingredients is not too much at all. As far as alternating day/night routines, there are certain serums that are much better when applied at night only because it will make you photosensitive (e.g. retinol). Other than these ingredients, you can use both at AM/PM and is better that way for your skin. I hope this was helpful!

    I’m thinking about taking pro hormones, do you think this is good idea for advanced bodybuilder like me?

    People are satisfied with the results after prohormones cycles, just google
    for – 100% pure muscles without side effects – worth a try?
