The product: A Pea in the Pod Tummy Rub Stretch Mark Oil by Mama Mio ($38)
Why people like it: This user said it did the job, but it left her skin more oily than she anticipated. "I have been using it through my pregnancy (began around 18 weeks, now I'm 31 weeks), and so far I am stretch mark free. The only reason I did not give it 5 stars is because it is quite oily. It does not stain my clothes, but I only use it after my shower at night because I don't like the feeling of the oil with my work clothes against my skin."
