Na hii husababishwa na aina ya "Skin Lightening Creams" ambazo huwa na viambata kama hivi:-
Skin lightening creams which also have different names such as skin brighteners, fade or bleaching creams, and whiteners, have one aim in mind. They reduce hyperpigmentation such as liver spots, melasma, and freckles by interfering the production of melanin.
Mercury
Using mercury to fade brown spots can cause Mercury Poisoning. Although mercury is banned in U.S., unfortunately, almost 1 out of every 4 Asian made skin lightening products sold in the U.S. contain this highly toxic substance.
As a heavy metal, mercury can be toxic to your body. Using it can leave you with kidney, psychiatric, and neurological disorders. If you are pregnant, you can pass the mercury to your unborn baby.
Hydroquinone
Hydroquinone is the standard ingredients use in hyperpigmentation treatment creams. For the over-the-counter products, the hydroquinone concentration is no more than 2% while the prescription ones usually does not exceed more than 4%.
Some claim that hydroquinone is not safe to use. It may cause ochronosis, an untreatable skin discoloration when used in very high concentration or on long-term basis.
When you shop for hydroquinone creams, it is important to check the concentration. Don’t buy it if the label does not state the strength of hydroquinone because you don’t know if it is safe to use. Some imported skin brightening creams exceed the allowed hydroquinone concentration and even some of their labels may report the wrong concentration.
Steroids
Some experience acne, skin infections, slow wound healing, and skin thinning when using steroids. If you apply steroids on large areas of skin, your body can absorb it, leading to potential health risks.
There are some risks when using dark spot removal creams. Practice due diligence by going through the label. Make sure the products are especially free of mercury as it is has the lowest safety factor.
