Does not reduce age sagging skin but does make skin soft. smells pleasant
Scent: Light Scented, Size: 26 Fl Oz (Pack of 1)
Used body wash for awhile along with the lotion. Doesn't firming like it says but kept my skin so soft and smooth. Smells good. Stopped using the lotion tho and did notice slight difference in sagging skin. So pretty much tells me works just not as good as expected. I do love the product overall. Must use faithfully for better results. Texture is great. Not to heavy.

This body wash goes above and beyond. I love the way it makes my skin feel, hydrated and soft. Also has a wonderful fresh smell. It's so much better than any hydrating bar soap. Leaves your bathroom smelling fresh too!!! Highly recommend!!!
