There are many ways to treat hyperpigmentation-the dark spots or patches that result from sun exposure, hormone changes and certain medications. The treatment that works best for you will depend on your skin tone, sensitivity and the type of pigmentation you have (sunspots, melasma or post-inflammatory trauma).
The first line of hyperpigmentation treatment is usually a lightening cream that contains an active ingredient such as trichloroacetic acid, salicylic acid, glycolic acid or hydroquinone. These can be found in a gel, cream or ointment formula. These typically work best on lighter forms of hyperpigmentation.
Another popular option is to use face acids that exfoliate the skin, removing the top layer that can lead to scaly or uneven texture and promoting the growth of new cells that are less likely to produce excessive melanin. These are generally used as spot treatments and can be purchased over-the-counter.
Natural home remedies include the application of milk-based products that contain active ingredients such as glabridin, which inhibits the enzyme tyrosinase that is responsible for pigmentation. Some people report that applying a milk mask to the affected areas twice a day can help lighten them.
Other options for treating hyperpigmentation include low energy laser treatments such as IPL and resurfacing lasers, which can reduce the appearance of darker spots, particularly those caused by sun damage. They can also be used to remove blemishes caused by acne or other traumas to the skin, such as the marks left by surgical scarring. hyperpigmentation treatment
