Is SPF 25 enough for dark skin?
"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."
What SPF is best for dark skin? The dermatologists we consulted recommend a minimum of SPF 30 — as does the American Academy of Dermatology. However, Henry recommends you apply SPF 50 if you're outside for more than an hour.
You Can Find a Sunscreen That Suits You
The American Academy of Dermatology recommends that everyone use a broad-spectrum sunscreen with an SPF of 30 or higher every day. People who have darker skin—and the slight protection that extra melanin provides—might be tempted to skimp.
Everyone, including those with dark skin, need to wear sunscreen every day. The American Academy of Dermatology recommends using a broad-spectrum, water-resistant sunscreen of at least SPF 30 every day.
A sunscreen with SPF 30 will protect you from around 96.7% of UVB rays, whereas an SPF of 50 means protection from about 98% of UVB rays. Anything beyond SPF 50 makes very little difference in terms of risk of sun damage, and no sunscreens offer 100% protection from UVB rays.
Technically, yes. With SPF 50, 2% of UV rays are able to penetrate the skin. That's how you're still able to get a tan even with a high SPF. So in order to prevent yourself from sun damage, you need to reapply at least every two hours.

Does SPF above 50 do anything?
The SPF rating only refers to UVB rays. An SPF 15 sunscreen blocks 93% of UVB radiation, and SPF 30 blocks 97%. After that, the difference in protection is small. SPF 50 blocks 98%, and SPF 100 stops 99% of UVB rays from reaching your skin.
Black skin, compared with white skin, is generally assumed to be more resistant to the consequences of sun exposure due to its epidermal melanin content. However, recent scientific evidence shows that black skin is not completely impervious to sunlight.
Sunscreen will cause hyperpigmentation if it has any one of these effects. 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.
However, in fact, some cases are reversed: the more you use sunscreen, the darker your skin, even some people have premature aging such as wrinkles, larger pores, acne and even aging.
