If you've been wondering, "Why is my skin becoming darker?" without obvious sun exposure, it's essential to understand that several factors could be at play. Your skin can react to many triggers, both internal and external. These include hormonal changes, medications, ageing, and stress.
Causes of hyperpigmentation include: Skin inflammation (post-inflammatory hyperpigmentation) Use of certain drugs (such as minocycline, certain cancer chemotherapies, and birth control pills) Hormone system diseases such as Addison disease.
Increased Melanin Production: One common reason for skin darkening is increased melanin production. Melanin is the pigment responsible for giving color to our skin. Hormonal changes, certain medications, or underlying medical conditions can trigger an increase in melanin production, leading to darker skin (1).
The hyperpigmentation related to vitamin B12 deficiency is more common in darker-skinned patients. Few other cases of skin hyperpigmentation due to vitamin B12 deficiency have been reported in the literature. The mechanism of hyperpigmentation is due to increased melanin synthesis rather than a defect in melanin.
Estrogen and progesterone are two of the major factors responsible for catamenial hyperpigmentation of the skin.
Your skin can develop darker patches as the result of excess melanin production, typically caused by skin inflammation, hormone fluctuations, and poor lifestyle choices. Age spots – also known as sun spots and liver spots – can also be signs of skin conditions, such as Melasma.

This can cause an overproduction of melanin, which can lead to the formation of dark patches or hyperpigmentation on the skin. Also, under stress, your bodies produce more inflammation, which can lead to increased pigmentation and worsen melasma symptoms.
Overview. Tinea versicolor is a common fungal infection of the skin. The fungus interferes with the normal pigmentation of the skin, resulting in small, discolored patches. These patches may be lighter or darker in color than the surrounding skin and most commonly affect the trunk and shoulders.
Humans with dark skin pigmentation have skin naturally rich in melanin, especially eumelanin, and have more melanosomes which provide superior protection against the deleterious effects of ultraviolet radiation. This helps the body to retain its folate reserves and protects against damage to DNA.
The reversibility of skin discoloration depends on the cause. Dermatologists can recommend treatments such as topical creams, laser therapy, or chemical peels based on the specific condition.
Dimness of vision may be noted due to muted color vision or gray areas. This is a symptom of a variety of conditions, including amblyopia, optic neuritis, retinal detachment, macular degeneration, glaucoma, cataracts, or brain tumor.
The Earth's Tilt – A Quick Science Lesson
Our planet, Earth, doesn't stand straight up as it orbits the Sun. Instead, it's slightly tilted at an angle of about 23.5 degrees. This tilt is what causes the different seasons throughout the year, and it's the reason we get more sunlight in summer and less in winter.
Irregular or patchy discoloration of the skin can be caused by: Changes in melanin, a substance produced in the skin cells that gives skin its color. Growth of bacteria or other organisms on the skin. Blood vessel (vascular) changes.
Lifestyle Habits and Skin Health: Bad habits like smoking, consuming a poor diet, and not bothering with a skincare routine might trigger skin darkening by contributing to factors like inflammation and oxidative skin stress.
Addison's disease: It causes patches of dark skin around skin folds or joints. Diabetes rash: If you have diabetes, you may develop discolored skin patches or spots. Medications: Some medications can cause your skin to lighten or darken. Cancer: Certain cancers or paraneoplastic syndromes can cause pigmentary changes.
Aging. Skin discolorations often occur in those over age 50. Just as other systems in your body experience wear-and-tear, your skin becomes thinner and drier as you age and is more prone to develop scaly patches and discolorations.
The incidence of this change varies, and depends on the type of medication involved. Some of the most common drugs involved are NSAIDs, antimalarials, psychotropic drugs, Amiodarone, cytotoxic drugs, tetracyclines, and heavy metals such as silver and gold (which must be ingested, not just worn).
Numerous variables, such as sun exposure, hormone changes, post-inflammatory hyperpigmentation, ageing, skin conditions, and lifestyle choices, can cause skin darkening. Understanding the underlying reasons will help us avoid or cure darker skin tones.
Thyroid hormone contributes directly to your appearance as you age. Thinning hair, dry skin, brittle nails, feeling tired and looking puffy are all results of low thyroid levels.
