Collagen + Retinol Anti-Aging Agents Serum

I like to use this in the PM, it nicely absorbs into the skin, and has no strong scent. Suitable for all skin types helps to smooth out the texture and reduce dullness. It has Retinol & Collagen, still doesn't dry out this skin as it also has Hyaluronic Acid. I found the formula quite gentle, though I recommend doing a patch test and also introducing this serum slowly to your routine.

I have been waiting for the perfect serum and this is it. The smell is delightful and the texture is just perfect. It goes on smoothly and a little goes a long way. I noticed results within a week of using it. My skin feels so smooth. I highly recommend.

I love, love this product, I love how this product is absorbed on my skin and how my skin feels the next day. 😍

I love this serum so much! It’s such a struggle for my dry skin to find something that exfoliates but still provides moisture. This serum does exactly that with the collagen. My skin doesn’t get irritated from the retinol and has a beautiful glow. I’ve noticed such a difference in my dark spots and acne. The texture on my cheeks that I haven’t been able to get rid of has finally started to smooth out!

I love the way this product makes my skin feel so soft and young looking yes it's the bomb and I will be ordering more!

I used it every day, but there was no difference. The reason I gave to stars, was that the product came quickly. But, I won’t be purchasing it again. I doubt this review will be posted though.

Collagen and retinol are such amazing products and I can tell MD has a good concentration coz it did not irritate my skin at all. The only thing however was the smell. I do know that lesser the fragrance the better it is for you.

I recently received the collagen retinol serum and the vitamin C serum from measurable difference. I’m in love with both of them! They are chock full of fantastic ingredients! They also are easy to apply and don’t leave my face all sticky like most serums!

I was new to Collagen based serums and I am glad I tried this one! My face feels so plump and supple in the morning. The texture is thicker not as slippery as most serums I have used but blends easily and sinks right into your skin nicely. I would recommend!

Received my order about 10 days ago. I had trouble reading the instructions because the print is so very small and I have an eye injury. I have been using the product very night for about seven days. I like the way it feels on my skin but have not seen any changes yet. I will continue using until the bottle is completed. by this time I will be able to write a more accurate review.
