The Serum of Your Dreams: Measurable Difference Collagen and Retinol Serum Review

How I Discovered Measurable Difference

I happened to be in Marshall’s a few weeks ago and stumbled upon their skin care aisle filled with what seemed to be inexpensive gems (eeeek!!). I walked out with this baby and a hyaluronic acid serum that I gave to my sister (you’re welcome, Moreen). Leaving Marshalls I was a bit skeptical because how can one find two amazing serums for ONLY $6 each?!

My Experience:

The first night using this product, my skin instantly felt plump and had a subtle, from within type of glow. I’ve used this for about 2 months now and I’m absolutely in LOVE. I cannot exactly say if it’s the retinol in this that has caused my dark spots to fade, because I have been using other products specifically for that. I WILL say, it definitely has sped up the process.

Also, I would recommend using this product only at night. Retinol is very sensitive to the sun and becomes ineffective after being exposed to sunlight for too long. Therefore, it would be a bit counterproductive to use this during the day. But it definitely would not harm you if you applied it during the day here and there, just don’t make that a habit.

By far my favorite thing about this is how much a little goes a long way! ONE drop is enough to cover my entire face. The more I put, the more I had to work to ensure it all was absorbed. Oh, it also absorbs very quickly which is a plus!

This serum has a very light consistency. It’s almost like water except a tad bit thicker. When it fully absorbs into your skin, it has a sticky but very smooth feel, which is amazing under makeup. It applies a bit slippery but fully dries down after a few seconds. I would recommend patting it into your skin as I received the best results when I did this and it also absorbs quicker this way. Again why this is best to use at night because who has time to pat a watery serum into their skin every morning? Surely not I!

How to Apply:

I applied this nightly right after toning. The few times that I used it during the day, I applied it after toning but before my moisturizer with SPF 30. It is crucial to wear SPF if you plan on wearing this during the day. Retinol and the sun do not go well together.

Overall, I would give this serum a 10/10. It has really helped moisturize my skin (the collagen part) as well as even out my complexion (the retinol part). I plan on keeping it in my daily skin care rotation because it’s just that amazing. I have absolutely no complaints (surprisingly). Wanna buy it? Check it out here

When I think about the main reasons I am so passionate about skincare, one of them has to be how skincare product formulation is constantly evolving for the better.

    I too found this at TJ Max and was skeptical because if the low price but figured what do I have to lose? I’ve been using this for about a month and it has changed my 51 year old skin that was feeling “ruddy”. My face is brighter and although I do not notice a decrease in fine lines I feel like it has been evened out. Will definitely continue to use this! Love it!

      Hi, Linda!

      I’m so glad you found this gem! It may take a few months of consistent use before you see any significant results with it. Keep me updated! 🙂
