All of our products are safe for use during pregnancy and breastfeeding, with the exception of our three Retinol Treatments (not to panic if you have used these products during pregnancy and breastfeeding since there is such little absorption by the skin – we are just being very cautious). The other thing we caution our customers on is that your skin does tend to change with pregnancy and breastfeeding. Some people notice their skin is dryer while others experience more oiliness and breakouts. You might select different products than you normally would. Most women find their skin is very sensitive to the sun so it is important to wear sunscreen every single day, even when it's cloudy or you are inside for most of the day. If you have particular questions about which products you should be using, email us at info@miracle10.com or give us a call at 1-877-515-8978.
