Age spots occur when melanin - the pigment that causes tanning - is produced in spots in higher concentrations than normal. Along with aging, UV light and tanning beds can accelerate melanin production, so wear sunscreen or stay out of the sun when possible, particularly if you're fair-skinned.
Product treatments: Age spots can be lightened with prescription skin bleaching creams. These bleaching creams can either be used alone or with retinoids and a mild steroid. Just keep in mind that fading creams are no quick fix - it can take up to six months to see results.
Hydroquinone is a skin-lightening substance that can fade out age spots. It is available in over the counter creams in low concentrations and through physicians at higher concentrations. Be careful with this substance, as it should not be used during pregnancy and can cause hypopigmentation (excessive lightening of the skin). Other non-hydroquinone bleaching creams have become available by a number of manufacturers.
