Measurable Difference MD Collagen Retinol Serum Universal Use

Does what it's supposed to do. 👍

I just purchased my 4th or 5th bottle. I now have dry skin which used to be a combination skin type. My husband came across an article about this acid and I decided to try. Considering that at the moment I use nothing but this product it WORKS even for my very dry dehydrated skin. I love it and plan on using it for a long time. Value is incredible! I use it at night but only for the reason that my puffy eye morning treatment cannot be used in combination with any creams. This product, Semantika and my eye lid cream make my face look like I had a surgical face lift.

It’s my go to after i wash my face every night. Doesn’t make me break out and doesn’t leave my skin feeling oily or heavy. I no longer get dryness from the weather that leaves my makeup looking patchy.

La verdad no conocía la marca y tenía mis dudas por el bajo costo del producto en comparación con otras marcas, sin embargo estoy maravillada, le cayó muy bien a piel y comenzó a reparar algunos problemas que tenía, no puedo quejarme, es excelente producto y está haciendo maravillas!

I originally purchased this to use in a lip roller. I ended up using it twice daily as the first step of my skincare routine (after cleansing and toning). It is the perfect serum as it hydrates and plumps my skin. Very impressed—it is a keeper!
