I usually use the Clarins Firming Bust Gel, but when I got pregnant, I was looking for something that uses as few chemicals as possible. This Mama Mio lotion is great - it's kept my skin firm and smooth despite my increasing bust size. It also absorbs quickly so you don't have to rub it in extensively which is nice when your breasts are sensitive and you don't want to tug your skin too much. Also, it smells very nice but is not overpowering at all.
Love this product! I started using it in my third trimester, mostly to avoid getting stretch marks. But then I read that it was great for re-toning after pregnancy so I used it for the first 3 months after the baby was born. It smells great, absorbs quickly and now that most of my pregnancy weight is gone I feel like my decolletage area is smoother and tighter.
