"Mask of Pregnancy":

Melasma, often called the "mask of pregnancy", typically results in dark patches on the cheeks, forehead, lips and nose.  It is believed to be a result of hormonal changes, sun exposure, or a combination of both.  Commonly used over-the-counter and prescription bleaching creams should be avoided during pregnancy, as studies have not been conducted on its safety during pregnancy.  Some examples of products that contain hydroquinone are the following: AMBI® EVEN & CLEAR™,Lustra, Epiquin Micro, Eldoquin, Melanex, and Tri-Luma Cream®.

Something Safe for Mom & Baby:

An ounce of prevention is a pound of cure with the use of sunscreen everyday, whether you are pregnant or not.  It can also help prevent melasma.  A physical sunblock with SPF 30 or higher will protect your skin from pesky free radicals, shielding it from cancer causing UV rays.  I highly recommend a physical sunblock such as Neutrogena® Ultra Sheer™ Dry-Touch Sunblock (SPF 55, 70 & 85) and the AVEENO® Continuous Protection® line.  It is important to just make sure the physical sunblock contains non chemical, insoluble ingredients such as zinc oxide and titanium dioxide, which protect against damaging UVA and UVB sunrays.  In addition, consider Vitamin C creams as well as glycolic and kojic acids, which are safe treatment options during pregnancy especially for melasma.
