Face Serums VS. Moisturizers : What You Need To Know

I come from a family of physicians, so when it comes to products that I use – especially on my face – I have to understand some of the science behind it.  My husband doesn’t show any empathy when I don’t think something is working AND when I don’t know anything about it.  That being said, I am a lifelong Eucerin user when it comes to moisturizer on my face , but lately I have been trying out face serums.  Naturally, I wanted to know what the heck they even are so I looked it up!

*Please note, the hydration body cream is NOT to be used on the face.  Please use an alternate face moisturizer to layer over the face serum.*

What’s The Difference?

According to WebMD, moisturizers have ingredients like petroleum and mineral oil to give it more density and in many cases creaminess.  With face serums, they have stripped out all the fluffing ingredients.  In doing that, serums are left with high impact, active ingredients like antioxidants, peptides (proteins such as collagen), and in the case of this active hydrating serum, hyaluronic acid (aka the fountain of youth).

What is Hyaluronic Acid?

Aside from being skin care’s biggest star of the moment, it is something that we naturally make in our bodies (babies have a ton of it which is why they have the best skin).  As we age we make less, which is why we use products infused with this molecule to help improve firmness and elasticity on our face.  The science is clear, check out this study which observed women who used hyaluronic acid for 8 weeks.

I have received several face serums lately, but in looking at the ingredients they are NOT all the same and so understanding what is in these products is important.  I was first introduced to Rodan and Fields a few years ago and have been a loyal Lash Boost user for years.  I also have had a great experience with their Bright Eye Complex product in the past (see my before and after photos here).  When I have had a good experience with a brand, I am more likely to consider other products in the collection.  That being said, I recently had the opportunity to test out and use their new Active Hydration  line of products and wanted to share with you why they are different, and in this case better!

The Science

By nature, human skin is ‘hydrophobic’ which means that our skin actually repels water which is why we don’t swell up when we go swimming.  With the Active Hydration Face Serum, they have paired up the hyaluronic acid with glycerin to help penetrate the skin and allow for the hyaluronic acid molecule to bind to it and sit on top of the skin providing a seal for hydration.  The science, down to the molecular level, is honestly downright amazing!

The Takeaway

I have used both the Active Hydration face serum and body cream religiously for two weeks and have loved my results so far.  I still have some uneven skin coloration so I may be headed for their Reverse collection next.

I hope that this review was helpful in understanding things that separate products from others.  If you have any questions, feel free to leave them below.  Want 10% off…email Neela Metgud at [email protected].
