Prescription Medications
Some people suffer from post-inflammatory hyperpigmentation, also known as hypermelanosis. It results from the overproduction of melanin in the epidermis or dermis layer. Certain types of inflammation trigger melanocyte hypertrophy, an activity that increases melatonin production. Infections, allergic reactions, trauma, and phototoxic eruptions result in hypermelanosis.
Dermatologists can recommend prescription medication for those with hypermelanosis, such as hydroquinone, tretinoin, and retinoids. Hydroquinone is a substance that acts as a skin-lightening agent. It bleaches the skin by decreasing the number of melanocytes present in the skin.
However, using hydroquinone takes about four weeks for the substance to take effect. Therefore, it can take several months of consistent usage before the individual experiences full results. Dermatologists can also recommend using hydroquinone to combat melasma, acne scars, age spots, freckles, and other post-inflammatory marks from eczema and psoriasis.
Hydroquinone doesn’t work on all skin tones and types. A person with dry skin can experience further dryness and irritation. The substance also doesn’t work that well for people with oily skin. It does work best for people with fair skin tones, and dermatologists warn against hydroquinone use for people with darker-colored skin tones as it can worsen hyperpigmentation.
