In terms of ingredients, most of the skin whitening and spot-clearing products contain hydroquinone and fruit acids, which may cause allergic reactions. For those with sensitive or allergic skin, using these products may lead to itching, redness and swelling of the skin. Long-term use of whitening products containing hydroquinone may also increase the risk of cancer.
In addition to allergic reactions, whitening products may also have side effects on the skin. Many whitening products contain high concentrations of ingredients such as fruit acids and niacinamide, which can weaken the skin's barrier function with prolonged use, making the skin more fragile and prone to damage.
Most skin whitening skin care products contain sunscreen. Although sunscreen is necessary, some sunscreen ingredients are controversial, such as zinc oxide and titanium dioxide. While these sunscreen ingredients are effective in absorbing UV rays, they can also cause skin sensitization and irritation. Therefore, you need to choose carefully when using these skin care products.
Besides the problems mentioned above, the long-term use of skin whitening and blemish removal skin care products may also lead to increased skin dependence. When you stop using these products, your skin may become duller and uneven. Therefore, we should be careful to use whitening products wisely and avoid over-dependence.
There is a risk of potential harm to the body from skin whitening skin care products. Although these products can help us improve skin brightness and lighten dark spots, we should be aware of the risks and choose the right products for us. If you are in any doubt, consult a professional or doctor for advice.
