If the sunscreen you wear stresses your skin (some chemical sunscreens can do this), it may cause skin darkening. Secondly, if you use sunscreen that has hormonally-active ingredients (like oxybenzone), it can cause hormonal skin darkening.
Does sunscreen lighten skin? Sunscreen deactivates UV radiation and therefore protects the skin from its damage. As a result of reduced production of melanin – the darkening pigment, the skin tone becomes lighter over time.
Because no SPF product can protect you completely, you can still get a tan while wearing sunscreen. And given that any tan, no matter how slight, indicates the body's response to damaging UV light, this isn't necessarily a good thing. You must be careful when outside for too long or when you notice skin tanning often.
An SPF also means that a certain percentage of skin-aging UVB rays are still allowed to penetrate the skin. According to the Skin Cancer Foundation , 3 percent of UVB rays can enter your skin with SPF 30, and 2 percent with SPF 50. This is also how you can still get tan while wearing sunscreen.
Health experts advise everyone, regardless of skin color, to use sunscreen with an SPF of at least 30. Although dark-skinned people won't get sunburned as quickly, they will still burn and are still susceptible to sun-induced damage—such as sun spots and wrinkles—and cancer .
Sunscreen only prevent sun tanning, it will not make fair. You should use Depigment creams to remove the pigment issues.

For many summers, people have slathered and sprayed on sunscreens and fretted about SPF factors while scrambling to protect themselves from ultraviolet-B (UV-B) radiation, a component of sunlight. Dermatologists have linked UV-B exposure to the development of skin cancer, including lethal melanomas.
Hydroquinone is a commonly used agent in skin whiteners, though the European Union banned it from cosmetics in 2000. It works by decreasing melanin production. Tretinoin, also known as all-trans retinoic acid, may be used to whiten specific areas. It may be used in combination with steroids and hydroquinone.
Effective treatment for dark spots and patches begins with sunscreen. Whether you're treating the dark spots on your own or seeing a dermatologist, using sunscreen is essential when you'll be outside. Applied daily, sunscreen can prevent new dark spots and patches. It can also help to clear existing ones.
"Pigmented skin types – those which rarely burn and tan easily – usually Asian or black skin – are relatively more protected than fair skin types from UV radiation due to melanin. Therefore, wearing a sunscreen with SPF 15-30 is likely to be sufficient."
When you're exposed to the sun, your skin creates even more melanin. Wearing sunscreen will limit this process. Sunscreen protects the skin from UV rays, which slow down your melanin production.

Sunscreen is designed to filter UV rays and prevent sunburn, but will not prevent the production of melanin, meaning that your skin will tan.
Why is my face darker than my body? Our face skin produces more melanin compared to the rest of the body parts, so our face skin is generally a bit darker. The harmful rays of the sunlight can damage the melanin cells and as the face is more exposed to sunlight, it is the first to be impacted.
How do they do it? Some sources indicate that they use chemical peels, surgery or lasers to whiten their skin. In fact, some strong creams such as Benaquin are used as well as drugs that can inhibit production of melanin.
