No need for dry chapped lips
After trying many different products designed to help your lips feel soft and healthy it was such a pleasure to find something that really worked! Vaseline is a brand that is tried and true so I wasn’t apprehensive about the purchase. I noticed an improvement right away. My lips no longer hurt or felt chapped and dry. There is no need to wait days or weeks for a solution. But it now!

Worked wonders on dry hands!
This is definitely very hydrating! Worked so well on my very dry hands without leaving a greasy feeling. I have noticed after using it on my legs they feel a little sticky, so not sure what that’s about. Overall satisfied though.

Miracle cream: excellent quality
I had dry skin. I come from a country that is very hot and being in this cold country. My skin has grown a little too thin. I really had to go to a dermatologist and he recommended this product and I recommended this product to him. I give a mile of 10 imagine I'm joining it. The foot carcasses if you have it. My carcasses are like a baby's feet really are. Can they buy it that they can buy it wherever they want from Walmart? I'm giving him a mile out of ten.

Best lotion I have bought.
Great relief for dry skin without being greasy! This is very important as I have looked for a long time for a clean and effective lotion like this. I keep the small tube in my lunch bag for work. I will buy this in bulk if I can. No odor I can detect. Gives my old skin a glow I haven't seen in many years and keeps my over worked fingers from drying and cracking.
