In terms of skin whitening, it seems like the most common advice we hear is: be sure to watch out for allergies... Some women, in their haste to become whiter, end up not only failing to lighten their skin after using whitening products, but also experience varying degrees of sensitivity and inflammation. In fact, those products that claim to be "quick-effect" often contain hormones, and long-term use can lead to health issues such as capillary atrophy and excessive hair growth. Especially for those with inherently sensitive skin, staying away from irritating ingredients and allergens is the first priority if you want to whiten your skin. Since whitening doesn't happen overnight, by making a little progress every day, you'll get closer and closer to having porcelain-like skin.
