The duration of SPF 50 is only last for about two hours. It means that you can reapply it every after two hours. It makes sense why we need to consider knowing the effect on people's skin. However, dark skin tone is more resistant to the sun's heat.

SPF 50 sunscreen should be reapplied every 2 hours or after sweating or swimming. Sunscreen can lose effectiveness over time, so check the expiration date.
