This shows how the negative messages people hear about skin tone can substantially alter their self-image and influence behavior. However, the reverse is also true — hearing positive messages may bolster self-esteem and reduce the desire for skin bleaching.
A 2019 study in Nigeria found that self-acceptance and education about the risks of skin bleaching could help prevent the practice.

Methods and ingredients
There are several active ingredients that can fade areas of hyperpigmentation. Some ingredients also reduce pigmentation in the skin more generally. Skin bleaching products may contain:
Vitamin C
Vitamin C may reduce spots of hyperpigmentation, including those from acne. A 2020 studyTrusted Source found that it is more likely to work at higher concentrations of up to 20%. Concentrations higher than this do not work any better.
Vitamin C can bind to melanin, reducing melanin production and addressing hyperpigmentation.
Niacinamide
Manufacturers often market niacinamide as an antidote to age spots and other types of hyperpigmentation. It is safe in small doses applied to the skin.
A 2020 study found that niacinamide could reduce hyperpigmentation when researchers used it as part of a blend that also contained tranexamic acid, kojic acid, and hydroxyethylpiperazine ethane. The study suggests using these products with antioxidants could address hyperpigmentation in skin of color.
Retinol
Retinoids such as retinol can help accelerate the skin turnover process, which may help the skin heal from injury. A 2021 studyTrusted Source found that retinoids can reduce post-inflammatory marks from acne, as well as hyperpigmentation in skin of color.
Retinoids are generally safe. However, forms such as tretinoin can causeTrusted Source adverse effects. These substances are also not safe for use during pregnancy or breastfeeding.
As with vitamin C, retinoids make the skin more sensitive to the sun, so sunscreen is necessary. It can also cause side effects such as:
dryness
peeling
stinging
Hydroquinone
Hydroquinone is a depigmentation agent that is present in many skin bleaching products. A person can buy a 2% solution over the counter or seek a prescription for a stronger 4% solution. Results usually appear within 3–6 months after applying hydroquinone one to two times per day.
Hydroquinone has many potential adverse effects. It can increase the skin’s sensitivity to the sun, so it is important to use sunscreen. Some other potential side effects include:
blue-gray skin discoloration
skin irritation and redness
burning
damage to the skin
skin dryness
false elevation of blood glucose on a blood glucose test that uses blood from capillaries
The WHOTrusted Source considers hydroquinone to be a “hazardous chemical.”
Mercury
Mercury is a toxic metal that harms humans and the environment. Despite this, it is in manyTrusted Source skin-lightening products, including soaps, creams, and other cosmetics. It inhibits the formation of melanin, resulting in a lighter skin tone.
People who use mercury-containing products on the skin may develop:
skin rashes
skin discoloration
reduced resistance to skin infections
anxiety
depression
psychosis
peripheral neuropathy
kidney damage
With enough exposure, mercury can cause death.
Mercury may appear on product labels under the following names:
mercury
Hg
mercury oxide
mercuric iodide
ethyl mercury
mercurous chloride
phenyl mercuric salts
However, not all manufacturers list their ingredients transparently, making it hard to know if skin lightening products contain mercury. Instructions to avoid contact with metal jewelry can be a warning sign, as mercury bonds to some precious metals, such as gold.
Numerous countries have banned mercury for cosmetic use, but not all. Even in places where it is illegal, it is often still possible to buy products that contain it online.
When people wash mercury-containing products off their skin, it eventually ends up in the ocean, where it can enter the food chain and contaminate fish. Eating these fish can also harm humans, as well as other animals.
Other ingredients
A 2018 systematic reviewTrusted Source found preliminary evidence to support the use of some other ingredients for treating hyperpigmentation but emphasizes a need for further research. These ingredients include:
aloesin
azelaic acid
turmeric
arbutin
green tea
ellagic acid
koji berry

eesults of skin bleaching
The results of skin lightening treatment, whether for specific areas or the whole complexion, vary greatly.
Safer ingredients, such as niacinamide and vitamin C, may modestly reduce hyperpigmentation. However, the extent of the reduction depends on the individual case.
Attempts to change the entire skin tone are often much riskier. It can result in patchy, uneven pigmentation or in hyperpigmentation, making the skin darker in places.
For example, hydroquinone can causeTrusted Source ochronosis, which is blue or black discoloration. Ochronosis is more common when a person uses hydroquinone at high doses.
Is skin bleaching ever safe?
Treating areas of hyperpigmentation can be safe if a person uses dermatologist-approved methods and avoids harmful substances.
However, attempts to bleach the entire skin are always risky, even if someone uses safer methods. It may causeTrusted Source:
an uneven skin tone
irritation, rashes, or eczema
discoloration
Globally, the biggest risk of skin bleaching by far comes from mercury.
The Minamata Convention on Mercury established an upper limit of 1 milligram of mercury per kilogram (mg/kg)Trusted Source in topical products. However, any amount of mercury is harmful. Many skin lightening creams contain more than this.
For example, a 2020 studyTrusted Source of Jamaican skin bleaching products found that many contained mercury, with six out of 60 products containing more than is permissible in the United States. Of the participants, 51% of women and 49% of men used such products at least once per day.
Even when mercury products are illegal, they are easy to obtain. The WHO calls this “a global crisis expected only to worsen with skyrocketing demand, especially in Africa, Asia, and the Middle East.”
Is it possible or safe to bleach skin at home?
There is no DIY or home remedy that can safely bleach the skin. The recipes people can find for this online may contain unsafe or risky ingredients. Even ingredients that do seem relatively safe may cause damage over time.
For example, some DIY skin lightening recipes call for lemon juice. Lemon juice is an acid that can exfoliate the skin and contains vitamin C. However, it is strongly acidic and can cause:
irritation
dryness
uneven skin tone and white patches
sensitivity to UV light
burns
For this reason, it is best to purchase skin products that are diluted to a safe pH level and that a third party has tested for safety.
Speak with a health professional before using any homemade or store-bought skin-lightening product, even if it seems safe.
