Skin changes are one of those unpleasant pregnancy symptoms that can mar this otherwise joyous period in your life. Melasma, also called the "mask of pregnancy," is caused by hormone fluctuations and appears as dark splotchy areas on your face. Fortunately, it should disappear after you give birth and your hormone levels return to normal; but until then, try these easy tips to decrease its occurrence and appearance.

Melasma worsens in sunlight, so avoid direct exposure to the sun and use a moisturizing sunblock with an SPF of at least 30 every day, regardless of the weather or how much time you spend indoors or out. Remember to reapply sunblock often throughout the day and, for added protection, consider wearing long sleeves and a hat when you're outside. Also, you should not tan in an attempt to hide the dark spots; it will only make them worse.

To cover up melasma on your face and even out your skin tone, apply a yellow-toned concealer and a foundation that matches your skin color. If the dark patches continue to bother you several months after giving birth, talk to a dermatologist about available treatment options.
