THE BEST LOTION I HAVE EVER USED
Scent: Sweet Vanilla & Soft Wood, Size: 18.5 Fl Oz (Pack of 1)
THIS WINTER AND HAVING THE HEAT ON HIGHER THEN I NORMALLY DO HAS DONE A NUMBER ON MY SKIN. IT IS SO DRY AND I HAVE TRIED SO MANY THINGS AND NOTHING HAS REALLY WORKED. SO I GAVE IN AND SPENT THE MONEY AND TRIED THIS. I AM SO GLAD I DID. THIS WAS WORTH EVERY PENNY. I LOVED IT SO MUCH I BOUGHT ANOTHER BOTTLE JUST TO HAVE SO I WOULDN'T RUN OUT. I START OUT WITH THE BODY WASH WITH THE OLAY SUPER SERUM BODY WASH AND JUST AFTER ONE WASH MY SKIN WAS MUCH SOFTER AND SMOOTHER. YOU DO NOT NEED A LOT AS IT LATHERS UP NICELY IT SMELLS GREAT AND IT RINSES OFF GREAT LEAVING YOUR SKIN FEELING CLEAN AND SOFT. IT DOESN'T HAVE A STRONG SCENT TO IT WHICH IS FINE . I FOLLOW IT WITH IT WITH THIS SUPER SERUM LOTION JUST TO MAKE SURE THE SKIN STAYS SOFT. THIS LOTION IS SO SOFT AND SILKY. IT ABSORBS QUICKLY INTO YOUR SKIN WITHOUT LEAVING YOUR SKIN FEELING GREASY. IT IS LIGHTWEIGHT AND LEAVES YOU FEELING SOFT WITHOUT THAT DRY CRACKED APPEARANCE. THE SCENT ISN'T VERY STRONG TO ME WHICH IS FINE BECAUSE I WEAR PERFUME SO I DO NOT HAVE TO WORRY ABOUT THE SCENTS MIXING. I DEFINITELY RECOMMEND THIS REGIMEN TO ANYONE SUFFERING FROM DRY SKIN.

4.5/5; Great product, but smells strong
Scent: Sweet Vanilla & Soft Wood, Size: 10 Fl Oz (Pack of 1)
Context: To start off, I should say that I have dry skin. Like, VERY dry skin. In purchasing this item, I wanted a product that I could consistently apply every single day to hydrate my skin. Product: The application of this stuff was like a dream. If you’ve ever tried using ANY sort of lotion (Lubriderm, Cetaphil, etc.) you’d know that usually it leaves that greasy texture on your hands that you have to wash off. This one doesn’t do ANY of that. The cream melts into your skin and absorbs very easily, unlike other lotions. I didn’t need that much to apply to my entire body. The results were great—my skin looked better and felt softer. If there was to be a con, it would be how strong the fragrance of the lotion is. This stuff smells STRONG. It’s not an unpleasant scent, but if you wanted to wear a perfume or body spray along with it, good luck because I can’t see a world where the cream won’t overpower or at least show through your preferred scent. TLDR Overall, good product with dreamlike application, but strength of scent could be dealbreaker for some.

This everyday body lotion is the bomb!
Scent: Collagen, Size: 17 Fl Oz (Pack of 1)
This body lotion is absolutely fabulous! It really does make the skin on my thighs and abdomen look and feel firmer and the skin on my arms, legs, hands, and feet is noticeably softer and more hydrated without looking greasy or feeling sticky. I even use it on my neck and my face, which has tended to be more dry than oily as I've aged. I also really appreciate that the scent is pleasant enough to stand on its own but subtle enough to work well with other fragrances. I don't think that I have ever been this satisfied with a health/beauty product at such an affordable price point. I even purchased a few extra bottles to gift to friends and family.

Wow - my new favorites 💜👍😀
Scent: Retinol, Size: 17 Fl Oz (Pack of 1)
I just purchased this and tried it last night for the first time along with the firming version. I didn't take photos because I was skeptical as a product I had purchased from a different line for more money didn't work. This morning I notice that not only does my skin feel more hydrated but the texture appears more smooth. I recently turned 75 & lost my husband a few months ago and having been a care giver for awhile and put taking care of me aside. These products and body wash are great and I like the fragrance. Please give them a try. To have something show this much difference over night is incredible. They are also affordable which is a plus for me. Thank you Olay.
