Retin-A is a topical medication used to treat severe forms of hyperpigmentation (dark spots) caused by certain genetic disorders such as melasma, erythrodysplasia verruciformis, and vitiligo. A number of other conditions are associated with dark spots including melasma, erythrogenic alopecia and vitiligo.
The most common form of hyperpigmentation seen in women is melasma. Melasma occurs when excess oil secreted from the sebaceous glands causes the skin to appear darker than normal. Other types of hyperpigmentation include vitiligo and alopecia areata, which affect hair follicles. These conditions cause patches of hair loss or baldness in some cases.
In addition to these conditions, there are many other factors that can contribute to the development of hyperpigmentation. For example, exposure to sunlight during pregnancy may lead to the growth of melanocytes (skin cells), which produce pigment. Some medications may also increase pigmentation levels. Women who smoke have been found to have higher rates of melasma than nonsmokers.
Melanoma is another type of cancer that affects skin and hair. Though rare, it can sometimes be linked to sun exposure, as well as some of the conditions mentioned above. In some cases, hyperpigmentation may be caused by an underlying medical condition that requires treatment. People who suffer from a skin disease known as erythrrodysplasia verruciformis may also develop hyperpigmentation.
Retin-A for Acne: What to Expect
Acne is a common skin condition that affects people of all ages and can lead to the development of permanent scars (such as hypertrophic or keloid scarring) that can affect someone for life. Most people tend to think they will ‘grow out’ of acne when they reach their twenties but many continue to suffer from breakouts into their thirties, forties, even fifties and beyond.
