According to the American Society of Plastic Surgeons, skin hyperpigmentation can be treated with one of several skin rejuvenation treatments such as prescription creams, chemical peels and laser resurfacing. Some skin care lines offer at-home chemical peels and moisturizers that slowly lighten the appearance of dark spots as well. However, these are not as strong as those used by dermatologists.
Also known as freckles, sun spots and liver spots, most skin pigmentation issues are caused by sun damage and the natural aging process. However, some point to an underlying medical condition. For example, melasma, a condition that commonly affects women during pregnancy, causes symmetric dark patches to appear on the face according to Johns Hopkins Medicine. Other conditions that can cause dark spots include pigmentation disorders, Addison's disease and psoriasis.
In addition to treating skin spots with over-the-counter skin care options, prescribed brightening creams and dermatological treatments such as laser resurfacing, it is vital to prevent future skin damage and dark spots by wearing sunscreen and protective clothing in the sun. Proper skin care is also essential. Some home remedies may help as well. Homemade masks containing lemon, honey, milk and orange peel can soothe, soften and brighten skin says New Health Guide.
